the ps5 soc are custom design and we have seen sony use tech from a forthcoming architecture on a current architecture before , ps4pro features
rapid packed math and the pro is polaris based , we didn't see rapid packed math on the desktop polaris cards .. they said rdna2 based gpu .. until
they say rdna2 gpu i am sceptical

Within AMD's official IPs:

RDNA = NAVI 12/10/14 Class = GFX 10 **

AMD has classified ARIEL (shaded) as GFX10 ** (RDNA) architecture as the 5700/5600/5500 in its Open IP.

It is known from AMD's documentation that RDNA2 is NV2 * (GFX 20 **) and indeed:

NV21 (Bignavi, high-end)

NV22 (upper middle range)

NV23 (mid-range)

This adds to the suspicions (from weeks ago) of Cerny's presentation where he highlights the Geometry Engine and Primitive shaders (Characteristics of RDNA 1) instead of its VRS / Mesh Shaders (RDNA2) variants.

Presentation of Cerny:




The official AMD documentation on the Primitive shaders / Geometry Pipeline in RDNA 1 mentioned in the presentation.



______________________________________

Finally the Epic demo intended to show the new features of PS5, does not strangely use any of the features of RDNA 2, and its presentation WCCF TECH highlights the following

According to Senior Graphics Programmer Brian Karis, Epic used PlayStation 5's primitive shaders (properly introduced by AMD with the RDNA 1.0 architecture), though the developers also made 'hyper-optimized' software shaders.

I personally think Ariel is an RDNA 1 customized to support some RDNA 2 features. There is nothing in the Sony or AMD documentation that indicates that it has full support of all the features of RDNA 2. We will see .....
Boy the PS5 is such a mess of a console.

Sony are the one who started finalizing the specs before microsoft ,it's expected to be weaker, but they are slightly ahead on next gen games development.
