The latest round of PS5 Pro hardware rumours suggest that AMD's RDNA 4 could lift Radeon ray tracing up to Nvidia's level

pcgamer.com:

The PlayStation 5 celebrated its third birthday last month, with Sony marking the event by releasing a chassis refresh (aka the unofficially named PS5 Slim). With that all out of the way, the interwebs rumour network is now in 'PS5 Pro' mode and there's much talk about what the beefier model will have inside its case. So let me bring you up to speed on what the current specs are supposed to be and what this could mean for PC gaming, if any of it happens to be true.

Just like Wccftech and Videocardz, I've been following the trail of PS5 Pro gossip on X/Twitter, following the usual crowd of reputable leakers. But let me just cut to the chase and summarise what's been said so far. To begin with, the CPU inside the all-in-one chip made by AMD will still be a Zen 2 design, comprising eight cores and 16 threads. The boost clock is reportedly going to be 4.4GHz, which is 0.9GHz higher than the standard PS5.

Not surprisingly, most of the changes are expected to be in the GPU. The PlayStation 5 uses a custom design, based on the RDNA 2 architecture that powers the Radeon RX 6000 series of graphics cards. It's not a massive graphics processor, with just 2,304 shaders and a boost clock of 2.23GHz.

The PS5 Pro's GPU is apparently going to be based on RDNA 3 but with some elements from RDNA 4. To increase the rendering capabilities, the shader count is going to be increased to around 3,712 (some sources are saying higher, others claiming it to be lower) but the boost clock will drop to 2GHz, to keep the power consumption down. Given that RDNA 3 compute units can be dual-issued with commands, it's potentially an enormous increase of shading ability.

But as we've seen with the Radeon RX 7000 graphics cards, games can't always utilise
