The most bestial data centers on the planet, gathered in this graphic

July 26, 2025 by usatoday24

The development of AI has promoted a New ‘Armamentistic’ career globally. It is not sought to dominate another territory, but to get the more computing power, the better. The main technology companies are deploying centers from Data around the world With a goal in mind: train the artificial intelligence. There are data centers that are authentic burged, and in this graph we can see the most powerful data clusters in the world with an outstanding protagonist: Elon Musk. Cluster. Before entering numbers, a nuance. When we talk about calculation power, we can talk about a computer cluster or a supercomputer. The latter is a system Extremely powerful which can be built with processors specially designed to reach extreme calculation powers or, most commonly common, from thousands of high performance servers. They are used for scientific simulations and tasks that require a huge calculation process, and its cost is brutal. On the other hand, We have the “affordable” version of a supercomputer: the computer cluster. It is a series of interconnected work stations that work in parallel solving problems. It is similar to a supercomputer, but the advantage is that It is a more flexible system Because, as you need more teams, you can expand the cluster. In addition, the components are more standard, which also allows the cost to be lower. But well, it is a concept that has blurred in recent years. The 100,000 club. That said, let’s go back to the graph elaborated by Visual Capitalist With the data of EPOCH AI. In it, we can see the most powerful clusters currently, but with some trap: they are both planned and operational. X, Elon Musk’s company, lit the XAI Colossus Memphis Phase 1 last year, a huge data center with 100,000 NVIDIA H100 GPU With the aim of training ‘Grok’, his AI model. It was something that He even surprised Jensen HuangCEO of Nvidia. It is a computing monster with an enormous calculation power, but the figure is expected to increase up to 200,000 GPU. We will see later the energy consequences of this. Following Musk’s company, we have Meta by stating that they have a cluster “greater than 100,000 GPU H100“For her model ‘calls 4’. Then there are those who maintain something else the mystery. For example, Microsoft with its cluster For Azure, Copilot and the OpenAi AI estimated they have 100,000 GPU between H100 and H200, Two worlds. Out of that 100,000 club we have Oracle With its 65,536 NVIDIA H200, another Musk company -you with the Cortex Phase 1 and its 50,000 GPU, and the United States Department of Energy with The Captainhe Most powerful supercomputer in the world. Officers or estimated, what is clear with this graph is that there is a country that has taken the calculation of AI seriously: United States. They are the ones that seem to push stronger with their data centers in the United States (of the 10 clusters, the first nine are in the US and the last in China) and are not only building inside their borders: Also outside. An example is the finish plan for Build data centers in Spain or the one who has practically Manhattan’s size. European expansion. In the graph, we can see two European clusters. On the one hand, The Jupiter from the Jülich Supercomputing Center in Germany with its confirmed GPUs. On the other hand, the Nexgen In Norway, with about 16,300 GPUs. Europe has undertaken several financing initiatives with the objective of Promote your competitiveness Thanks to programs such as Genai4eu and its budget of 700 million euros between 2024 and 2026. The objective is to build large data centers and, for the call of 2025, 76 proposals were presented in 16 different countries. Now, that development of the European AI must be aligned with Ai actthe agreement in force since February of this 2025 that ensures transparency and an ethical AI. Number vs. efficiency in China. Who has put the batteries in AI, beyond US companies, is China. Following one Road map very different from the westernChina is focusing on having (supposedly) less GPU working, operating with greater efficiency, much lower costs than those of American companies and with equivalent results. Deepseek or the most recent Kimi They are two samples of it. Nvidia rubs her hands. And of all this battle for AI, there is a clear winner: Nvidia. As much as it may be, and beyond who has more or less GPU to do the job, the clear winner is Nvidia. In China it is not so clear due to the commercial veto, but the main world data centers use Nvidia’s architecture with their GRAPHS H100 Y H200. And that if we talk about “normal” cards for AI, since they have the B200 with four times the performance of H100. In fact, the company seems so focused on that AI career that would have neglected what led by AMD for years: Your players cards. Those are servers of Lenovo data centers. Companies seek to reduce the footprint reusing hot water after dissipation to, for example, fill pools or showers. Image | Xataka The planet, not so much. And the consequence of that expansion of the AI is that data centers not only need huge energy amounts To function, also water to dissipate the heat of the equipment. There is an important absent in the graph, Google, which also operates its data centers for AI and that, together with others as goal or Microsoftneeds nuclear centrals to feed its facilities. Consumption is so exaggerated that renewables are insufficient during demand peaks, Using fossil fuels like coal or gas ( esteem That, the 200,000 Colossus GPU consume 300 MW, enough to feed 300,000 homes) and, as we said, the Water use has become discussion material in the candidate territories to house new data centers. So much dissipation needs China to already Building at the bottom of the ocean. In Xataka | China wants to become AI world engine. … Read more

The most “walkable” cities in the world, gathered on a map with an overwhelming winner: Europe

March 16, 2025 by usatoday24

Little by little, Europe has been expelling the car. It’s something that goes beyond low emissions areas: It’s almost cultural. The cities of the continent were designed tailored to the pedestrians in which the cobbled streets and the squares were usual and, although they have given way to the roads, that pedestrianization is coming back. And show that pedestrian power is this map elaborated by Visual Capitalist in which we see the 20 most passable cities in the world on foot. Spoiler: The 20 are European. The map. The data to prepare the map have been extracted from the study ‘A universal frame for inclusive cities of 15 minutes‘and the graph of The Economist And it allows us to visualize the average time that someone living in a city of 500,000 inhabitants or more has to walk to reach some basic service. These services or comforts include places such as schools, restaurants, stores or hospitals and, although cities must be scored to choose an order, the truth is that the average time is very, very similar among them. Average time. Thus, of the 20 most pedestrian or more passable cities on foot in the world, the first would be Milan (with an ideal center to walk, everything is said) and the last one would be Oslo. Of course, as we can see in the table that we leave below, the difference between them is not a nonsense: Milan 6 minutes and 24 seconds Copenhagen 6 minutes and 36 seconds Turin 7 minutes and 6 seconds Dublin 7 minutes and 24 seconds Lyon 7 minutes and 24 seconds Munich 7 minutes and 30 seconds Paris 8 minutes Marseilles 8 minutes and 6 seconds Genoa 8 minutes and 6 seconds Edinburgh 8 minutes and 12 seconds Berlin 8 minutes and 12 seconds Vienna 8 minutes and 18 seconds St. Petersburg 8 minutes and 18 seconds Bilbao 8 minutes and 24 seconds Bordeaux 8 minutes and 30 seconds MINSK 8 minutes and 36 seconds Stuttgart 9 minutes and 6 seconds Lille 9 minutes and 6 seconds Barcelona 9 minutes and 12 seconds Oslo 9 minutes and 30 seconds Characteristics. The European advantage over other countries and the characteristics that make cities more friendly to pedestrians are diverse. On the one hand, these big cities usually have historical centers that have been pedestrianizing or that were already. There are many examples, but cities like Amsterdam or Paris, among many others, They have gained ground to the car In recent years with more pedestrian areas of both the center and the school streets. Another important factor is that many of them were founded before the arrival of the car, so they were designed to reach everywhere. That is why there is a greater proximity to essential services and there is a green infrastructure such as squares, gardens and parks that are also inciting, in addition, to walk. On the other hand, public transport is also very developed, reducing the dependence of the private car. Advantages. There are many, but we can encompass them in one: health. Walking more and taking less the car implies that air quality improves because there is less pollution. Noise is also reduced, although these two factors are something that the electric car has potential to change. Having a more active lifestyle, it has positive consequences on health and the cardiovascular system and is something that promotes community life. Projects. All this has led to the fact that, as we say, Europe is friendly with the pedestrian, there are cities that are rethinking their urban model. In Spain, there are cities like Logroño that They have gained space to the car. Pontevedra is Another curious casewith 80,000 vehicles in the center in the late 90s only 7,000 in 2018. The idea is to have “15 minutes cities”And, although in Spain we already live in them, there are projects for large cities to be even more friendly. An example is the Supermanzanas of Barcelonahe XPANDE project of Burgos to convert 23,000 square meters into pedestrian areas, the regeneration of Bilbao, Valencia either Sevilleamong other large and small throughout the territory. Out of Europe? And, in fact, it is something that has been encouraged at European level. He WALKING PANEUROPE PLANor European Walking Plan, was an initiative to promote that pedestrian mobility throughout Europe, driven by common policies and focused on improving health. Outside Europe, then … there is everything. To find the first most passable city on the list, you would have to go down to 28th place, where Kyoto is. And, within the top 50, there are other cities that are not European such as Taipei, Katmandú, Taichung or Tokyo, all in the lowest part of the list. USA, Cochista region. On the other side of the end is North America. The United States and Canada are countries that have developed cities in a completely opposite way to European: prioritizing the use of the private car. The first on the list is Vancouver in 53 position and it is something that will be difficult to change despite the projects individuals of each city. The reason is that it is something cultural due to the urban design of its large cities, where suburban areas are They expanded big before and after Second World War and where the highways They won the ground to the neighborhoods very quickly, destroying communities and that model of “cities of 15 minutes”. Cities like Houston or Los Angeles They could not sustain themselves without the car, in fact. In the end, it is curious as, at least in Europe, the cities of the future seem to look at the past to recover a healthier and closest urban model.
