is that its creators do not know how it acquires emerging capabilities

by

A surprising idea is circulating among engineers who are dedicated to artificial intelligence (IA), and that sounds almost like a confession. It was raised by Dario Amodei, the CEO of Anthropic, in a essay published in April 2025 in which he acknowledged that not even his team fully understands how your AI models work. It is not an occurrence, although it may seem pure marketing. Deep down he is the CEO of one of the AI ​​companies most valuable in the world admitting in writing that his team doesn’t have the inner workings of their own product down pat. Most tellingly, Amodei is not alone. Geoffrey Hinton, award Nobel Prize in Physics in 2024 and one of the figures who has made deep learning possible as we know it, He said essentially the same thing. In other words: he only provided the learning algorithm; What happens next inside the machine is understood by no one, not even its creator. And Chris Olah, co-founder of Anthropic and head of its interpretability team, has been describing neural networks like a scaffolding on which the circuits grow on their own, without anyone having designed them directly. It is important that we keep in mind that we are dealing with three radically different profiles: a CEO with obvious commercial interests, an academic retired from industry, and a researcher who literally lives inside this problem. Even so, all three converge on the same idea, which also has a technical name: emergent capabilities, which are nothing more than abilities that the model did not have on a smaller scale and that appear suddenly when the size increases, without anyone having programmed them or seeing them coming. Scientific warning or sales pitch? This suspicion is reasonable and we are interested in stating it bluntly. Anthropic has built much of its brand identity around security and interpretability, versus competition, such as OpenAI or Google DeepMind, that prioritize rapid deployment. That its CEO publishes an alarmist essay about how little we understand about AI, when this company has been selling us for years the promise of being very careful with its models, fits perfectly with a commercial story: the more mysterious and powerful the creature seems, the more valuable the company that claims to be taming it is. Geoffrey Hinton left Google in 2023 precisely so he could speak without the ties of a corporate salary However, this reading begins to break down as soon as it is applied to Hinton. This scientist left Google in 2023 precisely to be able to speak without the ties of a corporate salary, he does not earn money from any generative AI company and his public discourse is systematically more pessimistic than any executive in the sector. You don’t have any products you need to sell or any funding rounds you need to justify. If this were only marketingit would be a marketing that does not benefit anyone specifically, least of all him. On the other hand, we should not overlook the work of Chris Olah, whose contribution does not consist of making statements: it consists of publishing scientific articles. The induction loops, the learning leaps that suddenly appear during training, the millions of monosemantic features extracted from Claude 3 Sonnet: This is all technical evidence accumulated over years, not a loose phrase in an interview. When Olah describes the inside of a model as arrays of billions of numbers from which we don’t fully understand how cognitive tasks emerge, he’s not selling anything. He is describing, with obvious frustration, the real state of a field that he co-founded. For this reason, the most plausible explanation is not the conspiratorial one, but the more uncomfortable of the two: it is probably true. The people who are building the most powerful AI models in the world appear to have no precise map of how and why those systems acquire capabilities for which no one explicitly designed them. This simply means that the convergence of an executive with incentives to exaggerate the alarm, an academic without any commercial incentives, and a researcher who has spent a decade documenting it empirically points less to an orchestrated campaign and more to an uncomfortable consensus within the field itself. The question that remains in the air, then, is not whether they are selling us smoke. It’s what happens when we continue to scale systems whose interior we still cannot fully explain, while the entire industry admits, almost in unison, that run faster than you understand.

will pay them up to 25% more pension if they do so

by

Although it is a stage of life that most of us look forward to, not everyone accepts the arrival of retirement. in the same way. There are people who, for the love of their profession or to continue running their company, decide to work beyond the age of 65. Others, however, do so under the obligation of a too fair retirement pension to face a cost of living that has not stopped rising. For the latter, we have good news. From now on, working beyond the ordinary retirement age will have a reward. The Government has decided to pay more to those who decide to return to work after retiring, and it will do so with a formula that until now was hardly used: the flexible retirement. The day opens wide. Until now, those who wanted to combine pension and self-employment could only do so between 25% and 75% of a full day. A very narrow margin for that would be profitable continue working beyond 65 years (or the 67 if the necessary contributions have not been made). Also, nothing self-employed in this formula. The new Royal Decree 416/2026which comes into force on August 28, changes that range by allowing retirees to work a day of between 33% to 80% of a full day. The other novelty, perhaps the most striking, is that the self-employed are entering this modality for the first time. They will be able to make their pension compatible with self-employed activity, as long as they have not been registered as self-employed in the three years prior to retiring. With more than 3.47 million of RETA members in May, the group is not exactly small. A reward for waiting six months. However, the entry into force of the Royal Decree comes with a detail that really does encourage those who have already retired to return to work. If you retire, wait at least six months without working, and then return to work, your retirement pension will increase significantly. If a retiree returns to work under these conditions to work between 55% and 80% of the full day, he or she will receive a 25% increase in the pension he or she received just before starting to work. With a working day of between 33% and 55% of the full day, the increase rises to 15%. “Our goal is for workers to have more and better options when it comes to retiring or combining employment and pension and now we propose an improved flexible retirement modality,” Minister Elma Saiz explained in a statement. Previously, the pension only decreased in proportion to the hours worked. Now there is a plus for coming back. Spain needs people to continue working. Behind this reform there is a serious demographic and financing problem: there are fewer and fewer young people contributing and more retirees earning for more years. According to the INElife expectancy at birth in Spain is already around 84 years, with women exceeding 86 and men close to 81. That is, there are more and more people with the right to collect a retirement pension, and they collect it for a longer period of time. Social Security, meanwhile, remains in the red. The system closed 2025 with a deficit of 5.58 billionalthough the data improves year after year thanks to employment. Let people extend their work life helps alleviate these bills, and that is why the Executive pushes in that direction from several frontsnot only with flexible retirement. Those who retire early are not so lucky. It’s not all good news. Who decides to retire before the legal age still suffers penaltyand especially those who have accumulated more than 40 years of contributions. Even if they have far exceeded the required period, a reducing coefficient cuts their pension just like any other early retiree. The collective, grouped in the association Asjubi40has been asking for this cut to be eliminated for some time. The Government has refused, and the reason is purely economic: removing that penalty would cost 3,358 million per year to Social Security.

80 years ago Portugal planted an Australian tree to stabilize its soils. Radically changed the way fires spread

by

In the 1950s, much of Europe resorted to large reforestation programs to curb erosion and supply wood to a rebuilding economy. Portugal, for example, opted for an Australian tree which seemed perfect to hold down their soils and feed their paper industry. Eight decades later, that decision is still written on the ground: it forever changed the way fire spreads across the country. The solution of a problem. to understand the current crisis You have to travel to Portugal in the fifties. The country was suffering serious erosion problems, large rural areas were being depopulated, and Salazar’s dictatorship sought to promote a forestry industry capable of generating wealth. That was the main reason that the eucalyptus seems to gather all the qualities imaginable: it grew very quickly, fixed degraded land and provided excellent raw material for the manufacture of paper. What then seemed like an almost unquestionable decision would end up altering the behavior of fires for generations. He not only planted, he transformed his landscape. The real change was not introducing a new species, but redesign the territory. Where previously there was a mosaic of crops, pastures and diverse forests, huge continuous areas of pine trees and, especially, eucalyptus trees began to spread. This new landscape was much more profitable from the economic point of viewbut it also eliminated many of the natural barriers that previously hindered the fire’s advance. Without knowing it, Portugal had created a scenario in which flames could travel for kilometers much more easily. Eucalyptus does not cause fires, it transforms them. One of the biggest mistakes is to think that the tree is the origin of the problem. Fires can start for multiple reasons, but the eucalyptus radically changes his behavior once the flames appear. Its essential oils are extremely flammable and, when they reach sufficient temperature, they cause the tree to burn with enormous intensity. Added to this is a fibrous crust It is easily detached and transported by the wind, converted into small embers capable of crossing roads, rivers or firebreaks and causing new outbreaks hundreds of meters from the main fire. Eucalyptus planted in Portugal When the forest becomes fuel. Fast-growing industrial plantations have little to do with a mature and diverse forest. Being practically made up of a single species, store less carbon long term and offer much less resistance to the advance of the fire than ecosystems where trees of different characteristics and a more humid undergrowth coexist. The result is a vicious circle: Fires return again and again to the same areas, making it difficult for the landscape to recover the diversity that would precisely help stop future large fires. Climate change and a threat. Increasingly frequent heat waves and prolonged droughts have multiplied the risk that this forest model already presented. This year and same as in SpainPortugal is once again facing one of its worst fire campaigns, with tens of thousands of hectares devastated and thousands of interventions by emergency services. The magnitude of the situation has even forced the Portuguese Government to activate the European Civil Protection Mechanism to request international help, aware that some fires already exceed the response capacity of a single country. The solution is not just to put out fires. The experts match in which fighting the flames will be insufficient as long as the landscape continues to favor its spread. The challenge is to recover mixed forests, reintroduce agricultural and livestock activities that fragment the continuity of plant fuel, and diversify forest species. In short, it is about rebuilding little by little a territory that for decades was designed with productivity in mind and not resilience against fire. The consequences of a decision from almost a century ago. The history of the Portuguese eucalyptus demonstrate that some political decisions transform a country far beyond what those who promoted them imagined. What began as an ambitious program to protect the soil and strengthen the economy ended up modifying the country itself. forest fire dynamics. Eighty years later, the great challenge no longer consists only in putting out the summer fires, but in reversing a landscape whose configuration favors each new heat wave to find terrain that is increasingly prepared to burn.

Someone had the brilliant idea of ​​sorting the IKEA catalog by assembly difficulty: it was just what we needed

by

It has happened to all of us at some point: we see a piece of furniture, a lamp or any small home accessory and for a few seconds we imagine the final result, already placed, as if it had appeared there by magic. Then comes the second image, much less pleasant: the box on the floor, the pieces spread out and that doubt as to whether we have the patience, the time and the necessary tools to finish it without regretting it. Buy something to ride It’s not just choosing a product; It is also accepting a small future task. That’s where it comes in IKEA Complexity Indexa website as simple as it is effective that turns that previous suspicion into a sortable table. It is not an official IKEA tool, and the site itself makes it clear by presenting itself as a fan project, but its starting point is very recognizable: gathering more than 21,000 products from the store and classifying them according to the effort that assembly may require. To accomplish its mission, it calculates a score from steps and parts, and adds data such as manuals, estimated time, and ease ratings. This allows us to look at the catalog from a very different question than the usual one: not how much it costs, but how much it will require of us. The price tells how much work remains ahead The page does not try to impress with design. As we can see in the screenshot, we have a table, a search engine, a category selector and a very specific filter to only be left with products that have a single PDF of instructions. From there, we can sort by price, steps, part types, total parts, manual pages, complexity or estimated time. There is an important precision: the prices are in dollars and the items link to the American IKEA store, so not everything has to be available in Spain or other European markets. IKEA Complexity Index has a simple design When we start sorting by complexity, the table leaves some quite curious scenes. At the bottom, products with a score of 1 appear, such as FÄLLSVIK mini glass door for BESTÅ furniture wave NYMÅNE work lamp with wireless chargingtwo articles that the index dispatches as minimal assemblies. At the other end, when consulting the page, a PAX corner wardrobe with 175,348 points and an estimate of 624 minutes. It is a large combination, with several associated manuals and a clear warning on the IKEA sheet: it takes two people to assemble it. The FÄLLSVIK mini glass door has a score of 1 on the IKEA Complexity Index The index also serves to dismantle a fairly convenient intuition: thinking that the most expensive will necessarily be the most difficult. By consulting the table, the JÄTTEBO Sectional six-seater It appears with a price of $5,345, but with a score of 684, very far from the PAX that we just saw. And something similar happens downwards: STRÅLA decorative screen and the UTSÅDD hook shaped like a cat cost $2.99, but they don’t demand the same by this metric. The first scores 40 points; the second, 6. The PAX corner wardrobe reaches 175,348 points in the IKEA Complexity Index The usefulness of this classification is better understood when we look at a job published in 2022. The Journal of Business Research analyzed reviews of IKEA products and found that ease of assembly weighed on satisfaction and subsequent recommendation. That is to say, it is not enough for the furniture to be pretty or cheap: how it treats us during the process also matters. The famous “IKEA effect” adds another angle, because putting something together can make us value it more, as long as we manage to finish it. In Xataka Neither buy nor rent: Navarra launches a housing model that also rescues barracks, mills and convents The best thing about this project is that it allows us to look at the catalog from another perspective. It is enough to organize a column so that a piece of furniture stops being just a pretty photo, a price or some measurements, and also becomes a promise of work. Before falling in love with a purchase, perhaps it is worth knowing how many pieces separate the initial illusion from the final result. And someone has thought about helping us in the process.

“We don’t see the promise of the four-hour work week reaching society. I don’t expect AI to change that”

by

Every technological advance brings the same promise: fewer work hours, more leisure time and a less stressed life for employees. It happened with the steam engine, with the computer and with the arrival of the internet. Now it’s up to the AI ​​to take charge. that collective illusion. Sam Altman, the man who more has pushed This wave with ChatGPT has just spoiled the party. He did it in a talk with host Ti Morse, on the podcast ‘Relentless‘. There he made a devastating statement: the founder of OpenAI does not believe that AI is going to bring the four-hour day. Not even now, nor ever. A promise that is never fulfilled. “For a long time, technology has promised people that they will work less and have a lot of free time,” Altman said. He acknowledges that this has been partly the case. Today we have more leisure and a better quality of life than decades ago. But that’s where the consolation ends for the dedicated employees. “For some reason, we never see the promise of the four-hour work week reach society on a large scale. And I don’t expect AI to change that,” the manager said. In itself it is a powerful phrase, but it is even more so coming from the founder and CEO of the company that has most promised to change work. as we know it. A game of comparisons. Why doesn’t it happen? According to Altman, human nature itself is to blame. “We always want more. We think of new things to do, to create for others, to wish for ourselves,” Altman justified. “It’s like a comparison game. People focus a lot on how they are doing relative to others.” That’s the key, according to him. Productivity does not translate into restbut in new goals. “I think we are all going to be much busier than we thought in a post-superintelligence world,” the manager concluded. “We will continue to complain, but secretly we will be happy.” Competition, he says, drives the economy and he doesn’t believe that will stop. What is already happening in the offices. The data, for now, give him some reason. a study of Harvard Business Review confirms it. After eight months observing a US technology company, he found that AI does not simplify work. Expand it and modify the processes. The report Work AI Indexfrom the Glean Institute, goes further in its conclusions. Workers spend an average of 6.4 hours per week just doing make AI work well: check errors, relaunch prompts, clean results. They call it “botsitting“Almost 70% admit to having submitted AI-generated work without reviewing it first. Not everyone thinks like Altman. On the other hand, Altman’s statements contradict what OpenAI itself recently published in its report Industrial Policywhere proposes just the opposite: 32-hour days without touching the salary, thanks to the so-called “efficiency dividends” that AI brings. Bill Gates is also among the supporters that AI will be a key piece in the arrival of the reduction of working hours. In a talk with host Nikhil Kamath, the millionaire founder of Microsoft assured that “you’ll be able to retire earlier, work shorter work weeks.” Jamie DimonCEO of JPMorgan, and Anthony Scaramucci also talk about three- or four-day weeks in the coming decades. The human that survives. Meanwhile, the technological labor market no longer aspires to reducing working hours, but rather to not continue losing jobs. According to Layoffs.fyimore than 200,000 people have lost their jobs so far this year in the technology sector. Altman himself recognized that many companies were using the AI as an excuse to apply the staff cuts that were carried out after the overhiring of 2021 and 2022. Altman, however, believes that certain aspects of human work are not going away. In his speech he used a curious metaphor: cooking for others. “You’re not creating much economic value in the world, but it shows love. I think people will continue cooking and eating together long after robots can cook just as well.” The four-hour day may still be a myth, but at least we will have the kitchen homemade.

“Regarding reading ability, there is no safe age for children to start using mobile phones”

by

Most millennials we don’t understand that children today have mobile phones since primary school. In my case, for example, I had my first cell phone in high school. A brick inherited from my sister. The point is that times change and it is logical that children begin to interact much earlier with technological devices. However, there is a lot of controversy regarding the ideal age for them to start doing it. Some experts believe that it is good for them to start early, while many others point out that it can be harmful. For example, there is a lot of talk about the effects it can have on the reading ability of the little ones. And they don’t just talk about reading without syllables. The main handicap seems to be in reading comprehension. They read, but they don’t understand the content. Neither age nor mobile phone use at school matters. In a recent studycarried out by UCLA psychologists, analyzed the effect of having a mobile phone on the reading ability of primary school children. 106 third and sixth grade children participated in the study. This, in the United States, is exactly equivalent to the third and sixth grades of primary school in Spain. All children had to take a reading comprehension test and answer a survey about mobile phone ownership. That is, they not only had to say if they have one, but also talk a little about their habits with him. It is important to emphasize that there were not only children of different ages. Culturally and linguistically different participants were also included. With all this, it was seen that children who have a mobile phone obtained worse results in reading tests. This effect was maintained in both third and sixth grade students and it did not matter whether they carried their phone with them at school or if they had left it at home. The language in which they normally spoke with their family did not matter either. From all this it is concluded that the problem is the possession of a mobile phone. Not the distractions that may be caused by school or the child’s age. There is no ideal age to start using a mobile phone, at least when it comes to reading. That is precisely what one of the authors of the study, Patricia Greenfield, said. in statements collected by Phys. The only exception. In the study there was one exception, referring to children from non-English-speaking families. In those cases, for those who had a cell phone, their reading skills were better when they used games on the phone and they had been texting with other children for a long time. It is an exception that, in reality, fits with other studiesin which it is pointed out that the problem is not in using the mobile phone, but in the use made of it. Using it to watch TikTok challenge videos is not the same as using it to use educational games. The same thing happens with television or tablets, for example. More than the ability to read as such, reading comprehension is affected. Beyond reading. In reality, reading is not the only quality that is affected by premature use of mobile phones. For example, there are studies that suggest that it can affect mental and physical health, increasing the risk of phenomena such as insomnia or obesity. In these cases, reference is made to age. In fact, in a study published in 2025negative effects inversely proportional to age were pointed out. And we’re not talking about very young children. In 12-year-old students with a mobile phone, a 60% increase in the risk of poor sleep and a 40% increase in the risk of obesity was seen compared to those who did not have this device. Observational studies. It is important to highlight that a good part of these studies are observational. For example, in the case of reading tests, a statistically significant correlation was found between having a mobile phone and obtaining worse results in reading tests. However, it cannot be proven that the problem is actually with the phone. As they say, Correlation does not imply causation. It could be more of a coincidence. In any case, there are many studies that indicate that screens are not the best allies in those stages in which the mind begins to develop. Of course we are more influenced by technology than we were 20 years ago. Perhaps it is not necessary to wait for a brick inherited in high school, but it is not the best idea in the world to give a mobile phone to a 6-year-old child.

If the question is whether trees and vegetation serve to combat the heat, the Bioparc of Valencia has the answer: 13 degrees less

by

Going out for a walk through the center of a big city at three in the afternoon in the middle of July is a great challenge for many people because they literally begin to roast due to the high temperatures. But in these situations, taking shelter in a dense park promises relief almost immediately, as has been demonstrated in different areas of Valencia such as the Bioparc, where the wind chill drops 13 degrees with respect to the asphalt environment, as its sensors have demonstrated. A question of perception. When we read “13 degrees minus”, our brain immediately thinks about the air temperature. And this is where it is important to qualify, since a tree is not going to take air at 40 °C and magically convert it into air at 27 °C. However, air temperature is only part of the equation. What really determines whether we are comfortable or on the verge of heat stroke is the cthermal comfort, measured by indices like PET (Physiological Equivalent Temperature). These indices take into account air temperature, but also humidity, wind speed and, above all, the average radiant temperature. On the street. Science in this case shows that direct solar radiation on our skin and the heat radiated by hot asphalt trigger our thermal stress. A specific study on shade infrastructure and outdoor thermal comfort demonstrated that urban shading can reduce the PET index between 9.4 and 17.1 ºC. Therefore, the 13-degree drop cited by the Valencia data fits perfectly with what science has been measuring for years. The air temperature does not drop drastically, but the radiant load does plummet. Why are trees so good? Here science has shown that tree canopies block direct solar radiation, and a field study of tree shading confirms that this interception of sunlight causes large drops in the mean radiant temperature under the canopy, eliminating the “oven effect” of direct sun. But they also act as a natural air conditioner, since, unlike a metal awning or pergola, which heat up and radiate heat, the trees are alive. This means that they absorb water through the roots and release it in the form of vapor through the leaves. This process consumes thermal energy from the environment, actively cooling the air around them, even if it is a few tenths or a couple of degrees. We need trees. The debate about whether to put more or fewer trees in a square is no longer a purely aesthetic or landscaping issue. It is directly a matter of public health, since science is quite clear that exposure to extreme heat triggers mortality and morbidity. That is why these natural environments act as a protective shield that is very necessary. It is no coincidence that institutions such as the Climate Cities Network are publishing technical guides to integrate “climate shelters” into urban planning. And it is no wonder because a climate shelter is nothing more than a space that offers safe thermal conditions for the vulnerable population during episodes of extreme heat. And the data makes it clear, since a well-designed park, with trees with wide, dense crowns, is one of the best possible refuges.

six seconds and a rope are enough to know who is good for the factory

by

Human resources departments increasingly devise more curious tests to detect certain qualities or candidate skills which are especially interesting for the since it is sought to be covered. As and how they counted our colleagues MotorpassionToyota uses one of those tests to recruit employees for its assembly line and it has gone viral as a result. from a video that has circulated on social networks. A wall with six pegs and a rope. Nothing else. Does this really help decide who works in a car factory? Toyota says yes. And behind this skill test there is more logic than it seems. One string, six pegs and no margin for error. The challenge that Toyota proposes to its candidates is called “Rope Twist” and consists of winding a rope around six pegs fixed to a wall. It must be done in a very specific order and direction. It is not worth rolling it in any way. There is only one correct path and it must be achieved in less than six seconds. A mistake in the direction of rotation and it’s time to start again. toyota confirmed to Jalopnik magazine that it is one of their “dojo training tools.” According to the Japanese manufacturer, the viral video was recorded at its Kentucky experience center and has years of history behind it. In reality, the test seeks to measure the candidates’ muscle memory and coordination ability under time pressure, just the skill they will need on a daily basis in their position on an assembly line. It is not the only filter. The “Rope Twist” is just one of the various skill tests with which Toyota tests its candidates. The Japanese brand also applies the “Flip and Place” challenge, a test inspired by the Minnesota test. This is a clinical test used for decades to measure manual dexterity and hand-eye coordination. In that case the complexity doubles since you have to use both hands. Ten pairs of hockey-like pucks must be rotated and placed in place. Toyota assures that it takes an untrained person about 20 seconds to solve this test. A plant employee does it in 14 seconds. The brand combines these tests with other similar tests such as passing bolts with both hands and assembling tiny parts against the clock. They all seek the same thing: to measure and train the ergonomics, rhythm and precision of the employees who assemble the parts of their cars. Why Toyota cares so much about the hand of each operator. These skill tests are supported by the Japanese obsession with always doing things equally well. Toyota has been relying on the kaizenthe philosophy of continuous improvement. Push each worker to improve your own processstep by step, without hurry but without pause. This attention to detail is part of the Toyota Production Systemthe model pursued by maximum optimization in production and eliminate any waste. It seeks to ensure that each car comes out with the same level of quality, no matter who builds it. That’s why it’s not enough for the company to know if someone winds a rope well. You want to know if that person will follow the exact procedure, without shortcuts. The result of so much rigor: the largest car manufacturer in the world. It may sound like a stretch to put so much effort into a six-second test. But the numbers support the methodology of the Japanese brand’s hiring system. Toyota was the largest in 2025 car producer of the planet with a production of 11.3 million unitsfar ahead of Volkswagen, which stood at 9 million. That number of cars is only sustained if each operator responds equally well, shift after shift, in all of the manufacturer’s plants. That’s where all these skill tests fit in. They look for hands trained not to fail, not creative geniuses with the rope. “They help illustrate how we invest in the training of our employees,” said a Toyota spokesperson.

We are at a time when we have to decide if upgrading the PC’s graphics card is worth it or it is better to eat for a month. Data center gobblers for AI have destroyed the RAM and SSD consumer marketand the rest of the components have gradually followed behind. The price of HDDs It’s crazy, motherboards have also gone up and graphics cards are a case study. It’s not that the stock is a drama sometimes or that it doesn’t even Nvidia neither amd have launched a renovation of their families, but prices have begun to rise a lot in a very short time. And there is more bad news: everything points to a new significant rise in Nvidia GPUs. Up to 30% for the third time so far in 2026. In short. As point According to Taiwan’s Economic Daily News, Nvidia is raising the price of GPU (graphics chip and associated graphics memory) packages to assemblers. It would be the third increase so far this year and we would be talking about an increase of up to 30%. In recent months we have seen increases in different ranges, with a significant one in May that only affected the RTX 5090 (already very expensive at base), but the economic newspaper expects that the new increase will affect all ranges. Translation. For landing it, NotebookCheck As an example, the Asus TUF Gaming GeForce RTX cost about $1,199 in winter 2025 and is now almost $1,600. In Spain it is something that varies a lot, but the trend that we see comparing prices on CamelCamelCamel is that in the last six months, prices have increased. There are others examples similar for the RTX 5070 Ti, with a rise of about $500 in just six months. After all, graphics cards also have memory. It is GDDR and not LPDDR or DDR like other consumer devices, but these modules are manufactured by the same three companies that have been abandoning the consumer market to focus on AI, and it would be the main component that is affecting the price of GPUs for gaming. AMD is not spared. The news comes just a few hours after AMD put us in a DeLorean to return us to 2022 with its new RX 9050 graphics. This is an entry model for which we do not yet have information on the price, but we do know that it will have a 64-bit bus and a VRAM of just 4 GB. It is a sufficient amount for undemanding independent games and titles from 10 or 15 years ago that we have pending, but in slightly more current releases (and I’m not talking about graphic marvels like ‘Halo Campaign Evolved‘ or such recent games) will be difficult to run even at a resolution of 1,080p. Brown also for Nvidia. Going back to Nvidia, although this whole situation is going great for them because have become the glue of the AI ​​industry with its platforms, the shortage will also reach them. Jensen Huang’s company is finalizing the launch of Vera Rubin, its new AI platform that is designed for both training and inference, especially focused on era of agentic AI. Well, according to a report by TrendForceit seems that Nvidia could cut Vera Rubin’s SOCAMM memory in half, going from 192 GB to 96 GB per module to control memory prices. We talked about that, per full rack, they would go from 55 TB of memory to “”””only”””” 28 TB, being an example that if there is no memory, there is no memory. The same thing would be happening to Huawei, by the way. The Chinese giant is preparing the supercluster to feed local industry of AI and would have asked CXMT to give them a ‘price’ to be able to acquire the RAM they need, but CXMT would have refused because is playing the same game than Samsung, Micron and SK Hynix in this matter of RAM production. Buy now…We have said it on more than one occasion. The best time to buy something was yesterday, but the second best time is today. No matter how expensive things are, which they are, everything indicates that they are going to get much worse before they get better (if they do, as companies like Lenovo they are not at all clear). With the consoles we have seen that Xbox Series and PS5 are more expensive (and quite a lot) today than when they were launched almost six years ago. nintendo switch 2 It had not even been on the market for a year when They announced a price increaseand even Raspberry Pi, which uses very outdated memory, has had a considerable rise. Nothing is spared and if you consider that you are going to need any device today, you better buy it as soon as possible because there is still a storm left for a while. In Xataka | There is a shortage of RAM because of AI. That will make your next console much more expensive.
