That video shows that frecuency has diminishing returns after a point and the more CUs of XBOX series X will make a difference. I think Sony strategy is pricing. |
It's a balancing act.
At some point driving frequency will not net you a linear increase in performance as bottlenecks in the design come into play. (I.E. Cache sizes.)
And the same with just adding more CU's, you eventually reach a point where you won't have a linear increase in performance as bottlenecks come into play. (I.E. number of ROPS.)
Digital Foundry was just demonstrating one aspect of this issue... And I wouldn't be using it as gospel of how the Xbox Series X/Playstation 5 scales in terms of clockrate or CU counts because neither console is using the exact same RDNA hardware as the Radeon demonstrated in that video so scaling will be completely different.
Sony and Microsoft have spent years working with AMD on fine-tuning their designs, they made the best decisions to meet their design goals and get the most performance possible, both consoles are great pieces of kit.

"And at the nuts and bolts level, there are still some lingering question marks. Both Sony and AMD have confirmed that PlayStation 5 uses a custom RDNA 2-based graphics core, but the recent DirectX 12 Ultimate reveal saw AMD confirm features that Sony has not, including variable rate shading."
This part seems to give credential to the post @Pemalite made that it is quite possible PS5 was designed on RDNA1 with some features of RDNA2. |
Pretty much just waiting on more info before I do a full breakdown on that... And what it could potentially mean for gaming... I do tend to get "information" before most people because of the Enthusiast tech circles I engage with.
