Unveiling New Details of PlayStation 5: Hardware Technical Specs [UPDATED]
Watch live for a deep dive into PS5's system architecture and how it will shape the future of games.blog.us.playstation.com
According to this:
"The new findings are very interesting as Sparkman and Arden have ray tracing and variable rate shading mentioned, while Oberon and Ariel don't. If they are indeed related to the PlayStation 5 console, this means that Sony will not be using AMD technology for ray tracing and variable rate shading."
PlayStation 5 May Not be Using AMD Hardware for Ray Tracing - Rumor
According to a recent leak, the PlayStation 5 may be using another hardware solution for ray tracing and variable rate shadingwccftech.com
If Sony did shoehorn RT support because they had their pick of selections of RDNA2 features they can add on without increasing the complexity and price. But didn't pick Mesh shaders and VRS for some reason. Then OP would be right.
Why I don't hold any belief either way. It is interesting that they marketed RDNA 1 (Primitive Shaders, Geometry Engine) features rather than RDNA 2 features (Mesh shaders, VRS). Again I don't believe it but its an interesting thought process.

I care if next-gen is 1440p at 30 fps. I would be disappointed.
They need something to point to as a 'win' after their games start coming out...

Primitive Shader: AMD's Patent Deep Dive
Primitive shader was mentioned in The Road to PS5 video, many suspected it was just another term for Mesh Shader, some said they are different concepts and thus PS5 would not support mesh shader. AMD's own marketing did not help clear the confusion, so I decided to take a look at their patent...
It's just a bit of fun... the last game there in the meme will be on PS5 too.
I don't mean to be rude, but honestly, your kind makes me go mad. Fps I can understand somehow, even though I like 30 more than higher fps (it reminds me of soap operas) but why do you care so much about the resolution? Do you really think Pacman in 120k looks better than a game that looks like Avatar in 720p? The people like you who only care about these numbers will be the reason if nextgen will feel again a small step compared to the previous.
What a way to overreact... Guess this is already the time for me to leave this thread.
Brother it's ok for different people to care about different things, trust me. The world is better that way.
Well, there it is. Github was fully true. The only thing RDNA2 in PS5 is the clock rates and thermal profile to run at such high clocks. Features are RDNA1.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 .....
Perhaps an old soc thing is in this particular instance I will choose to believe Cerny and Lisa and Sony's blog stating the PS5 gpu is RDNA2. Hell if I'm wrong and the people that helped engineer the PS5 gpu are all lying I will gladly fall on that sword. Still think title change is needed.
That's the thing, they won't. Just like no game has matched the UE4 PS4 tech demo.
I didn't mean to offend you, so sorry if it felt like that. It is just that I really can't understand how can resolution be so important for so many people when it's not the main component of graphics that defines a game.
