TFLOPs aren't everything: The PlayStation 5's 10.3 TFLOP GPU is a custom RDNA 2 part with 36 CUs running at 2.23 GHz

[Redaktion]

Sony's Mark Cerny spoke in detail about the PlayStation 5's GPU, which is a custom designed AMD RDNA 2 chip. The PS5's GPU has a lower CU count than the Xbox Series X but has higher clocks and boosts differently compared to PCs and the Xbox. Sony intended to drive home the point that TFLOPs alone do not account for all the factors that collectively impact GPU performance.

Not as pretty as the leak, also the notion that fewer CUs at higher clocks provide better experience seems counterintuitive and could use more clarification.

Instead of "better experience", the right way to look at it is how much of a practical difference does the the 1.8 TFLOP difference make in real life when comparing both consoles head to head. You are already creating games that can leverage the full GPU. Running faster fully saturated 36 CUs may actually be more useful than semi-used slower 52 CUs.

Those stuff can be done with software or shaders. It still sounds like mostly shader based ray tracing. No mention of path tracing.

Yeah probably gotta do with those reduced CUs. This might have a cost benefit though.
