While we already discussed the latest speculation surrounding the PS6 Portable yesterday, leaks continue to come thick and fast. This time, attention is turning to the main machine: the future PlayStation 6. Several alleged technical details, revealed by the leaker Kepler (already behind revelations about the PS5 Pro), allow us to glimpse what Sony could be preparing behind the scenes for its next generation of home console... and the close ties it could have with the portable model.
An architecture tailored for AI and performance for the PS6
According to the latest rumors, the PS6 should be based on a 3nm chip, with a power consumption of 15W. That's relatively low for a home machine, but it suggests Sony may be banking on increased power efficiency, likely with a view to dissipating less heat while maintaining high performance.
The PS6 is reportedly confirmed to have 16GB of RAM, a configuration equivalent to the PS5, but this memory would come with new components, such as 4MB of L2 cache and 16MB of MALL (Memory Access Level Layer), which are absent from current models. These additions could significantly improve loading times, multitasking, and texture management.
The integration of AI at the heart of the system
Another central element is the PS6's artificial intelligence upscaling. Sony is said to be using AMD's new capabilities in this area, via the RDNA 5 architecture, or even a derivative called "UDNA." These technologies would allow the console to offer finer and more detailed graphics, without increasing the raw computing load. This system would be particularly useful in the context of high-frequency 4K gaming, or to maintain fluidity in the most demanding titles. Kepler specifies that RDNA 5 and RDNA 6 would both be based on the same base, dubbed "gfx13", which suggests technological continuity rather than a clear break with the previous generation.
Even if the subject has already been widely discussed for the PS6, it should be noted that several of these technical rumors concern both the home console and its portable version. The Low Power Mode recently mentioned for the PS5 would serve, according to some sources, to simulate the performance of the future portable console. This mode would drastically reduce the memory bandwidth, which would correspond to the supposed limitations of the portable model (about a third of the PS5's bandwidth).
Sony therefore seems to be working on a complementarity between its two formats. All in order to facilitate the porting of games and maintain technical consistency between the platforms. Developers would have to make little effort to adapt their titles... Which could guarantee a rich catalog from the start of the new generation.
