DDR6 memories promise a new era for the PC. And also a new way of riding them

The next generation of RAM memories It is getting closer. While we continue adapting to DDR5the industry It already works at full speed in the DDR6, which promise to double the current performance and arrive in a novel format for the domestic user. Under these lines we wanted to collect everything we know about this new version so far.

Vertigo speeds. DDR6 do not promise a simple evolution. And they will also offer a radical change in memory architecture. With Minimum speeds of 8,800 mt/s According to the Jedec standard and the possibility of reaching 17,600 mt/s, they practically double the performance of the current DDR5. Samsung, Micron and Sk Hynix They have already passed the prototype phase and work together with Intel, AMD and NVIDIA in the validation processes.

THE SECRET OF THE PERFORMANCE. The key is in The new 4 × 24-bit sub-channel architecturecompletely different from the 2 × 32-bit structure of DDR5. This change allows to manage more data simultaneously, but also introduces new challenges in the integrity of the signal. Jedec is evaluating the use of NRZ standard (Non-back to zero) For communications, abandoning the current PAM system that already shows limitations with the highest speeds of DDR5.

Goodbye to traditional modules. Here comes the most visual change: DDR6 is likely adopt the CAMM2 formatwhere the modules are placed in parallel to the motherboard instead of perpendicular such as the Dimm and So-Dimm of a lifetime. This modification has its explanation. And it is that the current Topology of the memory slots generates interference that limit the maximum speed up to 400 mt/s. CAMM2 eliminates these problematic welded connections and transfers signal management to the module itself.

A change when setting up a PC. The change of format involves completely redesigning the motherboards, but opens new possibilities. CAMM2 connectors could be located at the back of the plate, allowing more compact factors. Although initially require several screws for their fastening, Jedec works on installation systems without tools. In parallel, everything indicates that we will see more portable and Mini PCs with Solded memory directly (something increasingly common today), sacrificing the ability to expand for better performance.

In a few years. The deadlines are more or less clear. The validation of platforms will begin in 2026, they will reach servers in 2027 and the availability for consumers is expected to be between 2028 and 2029. This staggering is similar to that with DDR5, but analysts predict faster adoption in artificial intelligence environments and high performance computing. Everything indicates that the initial prices will also remember those of DDR5 in 2021, limiting early adoption to data centers and research laboratories.

What comes after. DDR6 will not only offer more speed: they promise greater energy efficiency and higher capabilities thanks to New NAND chips in development. For players and content creators, it will mean more bandwidth for work loads that involve AI and demanding applications. However, this evolution will require new motherboard, compatible processors and a different way of mounting a PC.
