The GPUs in the PS6 and next gen Xbox hardware will allegedly use AMD’s UDNA architecture, allowing for 20% improvement in rasterization and 2 times in Ray Tracing and AI over RDNA4.
Hardware insider KeplerL2 took to the NeoGAF forums to respond to a fellow member’s comment on the PS6 potentially doubling, tripling, or even quadrupling AI upscaling and Ray Tracing performance over current-gen PlayStation hardware. In his response, the insider shared that both the PS6 and next Xbox will use the same GPU architecture, referring to AMD’s UDNA, so the improvements in Ray Tracing and AI-related performance will come for both consoles.
Launch Year
Regarding when both consoles will see the light of day, the insider stated that both are likely to be launched in 2027, though him and other people in the know are aware that Microsoft wants to launch ahead of the PS6. As such, a 2026 launch for the next Xbox may be possible, especially given that the company is, as per them, releasing some of its biggest games next year, namely Halo CE Remake, Forza Horizon 6, and Gears of War E-Day. Of the three aforementioned titles, the latter is the only one that has officially been announced thus far.
PS5 & Next Gen Xbox SoC Customization
On SoC customization specific to PS6 and the next Xbox, KeplerL2 mentioned that both Microsoft and Sony vastly overstate the degree of customization they make to their respective console’s AMD chips, and most of the time it’s entails re-adding features that the chip maker removed from recent architectures in order to enable backwards compatibility or removing features they don’t use. In terms of actual CPU or GPU performance, they said that it’s 99% AMD’s work that matters.
RDNA4 vs UDNA
As for the expected gains that AMD’s UDNA architecture will offer over RDNA4, the insider estimated around a 20% improvement for raster performance and around 2 times better Ray Tracing and AI-related gains. He added that neither console will feature 3D cache. As of now, he is not aware of the number of Compute Units (CUs) present in each consoles GPU.
