PS5 GDC Reveal and PS5 specs/performance Digital Foundry Video analysis : 3.5 Ghz 8 core Zen 2 CPU along with 10.3 TF RDNA 2 RT capable and 16GB GDDR6 RAM and also super crazy fast 5.5 GB/Second S

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.

Will look for your breakdown and also to compare with whatever "professionals" do, because except key folks on DF and Ars Technica I wouldn't trust other "pros", so you and CGI would be a good comparison from SW and HW side of what to expect.

From "Pros" we got from negilible difference, to PS5 is the most revolutionary console, to XSX advantage is massive. While it mostly is XSX is more powerful but the around 15% power difference won't be noticeable for most gamers since the output on the TV will be 4k30fps or the like.
