According to KeplerL2’s latest disclosure on the NeoGAF forum,Although Sony PlayStation 6 will use AMD RDNA 5 architecture, it will not fully support all the features of this architecture. This move is obviously due to cost control considerations.There is a precedent for a similar strategy on the PS5. The PS5 is actually a combination of the RDNA 1 architecture and part of the RDNA 2 light tracing function, rather than pure RDNA 2.
The PS6 will continue this idea and may only select the parts of RDNA 5 that have the most core impact on game performance, such as the greatly improved ray tracing performance.
Previous estimates from Moore's Law Is Dead suggested that the PS6's computing power would be about 34-40 TFLOPS, and its light-tracing performance would be 6 to 12 times higher than that of the PS5. However, in order to avoid the rising costs of silicon chips and memory, Sony had to abandon some unnecessary features.
In addition, analyst David Gibson has predicted that Sony is considering postponing the release window of PS6 from the original 2027 to 2028 or even 2029 due to the skyrocketing price of global storage components, which means that the life cycle of PS5 will be significantly extended.
Mark Cerny also revealed that PS6 will be equipped with three core features:
Neural Arrays neural array unit realizes collaborative computing similar to a single AI engine;
Radiance Cores ray tracing core provides high-performance real-time ray tracing and path tracing;
Universal Compression technology significantly reduces memory bandwidth pressure.
