Sony says the GPU in the PS5 Pro is mostly very old tech but previews the ray-tracing upgrades from future RDNA 4 graphics for PCs

The GPU in the hot new PlayStation 5 Pro is mostly pretty old tech. But it does preview the ray-tracing upgrades that are coming with AMD's new RDNA 4 graphics chips for PC gamers.

That's the low down from the same PS5 Pro deep dive that also revealed Sony went its own way with AI hardware in the console rather than using AMD technology.

Sony's lead architect for its PlayStation consoles, Mark Cerny, has explained that the GPU in the PS5 Pro is still RDNA 2-based at its core, just like the original PS5.
