A Closer Look at How Xbox Series X|S Integrates Full AMD RDNA 2 Architecture

Whats embarrassing is people fighting for a piece of plastic constantly trying to claim they are smarter than everyone else and then when its proven for the 100th time they are talking out their ass they still double down.

These threads wouldnt be so toxic if that didnt happen.

I am not sure if you included me in that? I am just interested in hardware and is still curious about the customisations to the PS5 chip with regard to RT, geometry engine and cache management system. I had hoped to get more information regarding the infinity cache today in general but the presentation was very thin - that was disappointing. Still believe the PS5 has a larger than assumed L2 cache (that both addressed the cache-management system and the RT since RT is very memory intensive cache wise).

I am still of the belief that the PS5 has worked hard in those three areas and more information is to come.

Sony claimed PS5 is RDNA2.

MS claims Series S/X are the only fully integrated RDNA2 consoles.

It can literally mean PS5 is 1% RDNA2. You'll never know because Sony shut their mouths about RDNA2 feature set.

Look at the quote.

With the upcoming launch of the Xbox Series X|S on November 10, together we are ushering in the next generation of gaming delivering a level of power, performance and compatibility never before seen in console gaming, powered by AMD’s latest “Zen 2” and RDNA 2 architectures. Xbox Series X|S are the only next-generation consoles with full hardware support for all the RDNA 2 capabilities AMD showcased today.

PlayStation 5 doesn't support sampler feedback
PlayStation 5 doesn't support DirectX Raytracing.


PlayStation 5 has their own custom hardware.


It's PR bs as usual and Xbox fanboys are falling for it again.

If that is the case why the hell were they so coy with it for all these months, including back-tracking on wording that included RDNA 2 and replacing it with simply 'RDNA' as an example?

Lmfao, so MS went with standard RDNA2, while Sony customised theirs?

And this is meant to be a bad thing?
Well, MS also has customised hardware. But pretty much.

EDIT: Yes, standard RDNA2 though, with a few bells and whistles.
Sony just swapped out some RDNA2 features and replaced them with their own versions.

Have cancelled my PS5 pre-order, set my PS4 on fire and have sent my shit in a letter addressed to Jim Ryan.

Fuck you Sony.
Yes, I just put my PS5 pre-order up for sale...

I see the error of my ways. I cant wait for next E3, the best Xbox E3 ever and Chris Lee's masterpiece of a game next year....it will truly showcase the ultimate graphics the industry has to show.

Xbox it going to win Japan over in a year and make everyone hate Nintendo and Sony and see how anti-consumer their games are...with the lack of options to pay for skins and paints for your muscle-man armor.

I hear all of Europe has returned their PS5 pre-orders now and are really excited about how much RDNA2 Xbox is.... it's so much RDNA2, SO MUCH!

It's a monster that also eats monsters for brunch and 12 tflops to the power of X...X gon give it to ya.....

Goal post has moved geordiemp geordiemp now says its rdna 3 in the spec thread guys. We'll just have to wait a little longer for that event


this troll account was trying to mind gymnastic that ps5 has infinity cache :messenger_unamused:

boom! in fact, only MS has experience with amd on gpu cache

The generation is long. Time will tell how well these features will be implemented in the long run.

I am curious to know if this means Xbox Series X includes Infinity Cache. the article does say "all the features" after all.
 
This thread is slightly embarrassing. And to be honest I think the MS marketing team should also be slightly embarrassed with themselves.

But you could argue that it is working given some posts in this thread. The key sentence is: "Xbox Series X|S are the only next-generation consoles with full hardware support for all the RDNA 2 capabilities AMD showcased today."

So it is not that they have all hardware features of RDNA2. it means they support all RDNA2 capabilities that was shown today. Or in other words there is at least one feature on this slide that Sony has chosen to have their own solution for:

So the Xbox series X has full hardware support but not all hardware support what the hell are you talking about?

No, Sony have been consistent in saying the PS5 has a custom rdna2 gpu, Lisa Su also tweeted something like 'it's great seeing rdna2 in action' after the UE5 demo.

And yes, Sony have quite a long history of not publicly revealing information about their api feature set.

XboxGAF doesn't realize that this doesn't mean PlayStation 5 isn't RDNA 2.

Watch RedGamingTech video. Sony doesn't need all RDNA features for console.
I knew this Sony employee wasn't BSing back in the spring.


Rosario Leonardi, an engineer at Sony Computer Entertainment Europe, gave us some interesting explanations, responding to a private message on social media: “I know you are curious, but I am legally bound and I cannot say anything that has not been made public. As you probably know, the architecture of PS5 is a middle ground between RDNA1 and RDNA2, with unique characteristics. Even PlayStation 4 Pro was a sort of hybrid between GCN2 and 4 ". Recall that for RDNA we mean Radeon DNA and it is a GPU architecture coming out in 2020, which should provide a 50% improvement in performance compared to RDNA1.

XboxGAF has been told for weeks by pseudo-engineers/bullshitters like geordiemp geordiemp that Series X/S wasn't full RDNA2 and the reckoning was coming on Oct 28th. We're mostly just relieved these FUD spreaders are confirmed to be wrong.

I've always maintained there will be parity between the consoles and I still believe it 100%

He had to backtrack because the pitchforks came out. Twitter is such a toxic site.

I mean, if Sony made up their own equivalences I don't see what the big deal is? We'll find out soon enough which solutions are better, won't we?

It has some of the full feature set in parts customised by Microsoft to be 100% RDNA2 in certain parts of the complete range of the architecture.

I hope that clears things up for you.

You are correct but the point is more there are many that tried claiming that XSX wasnt RDNA 2 and are still trying to claim it now.

As was pretty well explained in the RedTechGaming tweet and as I said in the other thread, they can only say this due to DirectX features being the focus of the PC GPUs, and Xbox using directX. Since PS5 doesn't use directx, they can't "technically" say the have the exact same features, but they really do. Sony just has they're own custom version of it.
People that use RedTechGaming as source should be banned

Don't forget that infinity cache could have been under NDA's at that time.
So where are these MBs of cache in the 360mm2 Series X chip?
I have only two pics from them.

That render from the Xbox video.
SOC-1400x700.png


And that X-ray from the Hotchips:

Both are the full 360mm2.

I know what it means, was just confused why he just posted FUD when I only quoted the article.

But what you said just confused me more.
So far I got that it's Software RT with dedicated hardware to accelerate it.
But now you're saying it's not software based so how can it be Hardware Accelerated if it has hardware based RT Cores?

All RT is initially software based off of the API (direct x 12 in this case) and then GPUs can accelerate that so that there's enough compute power to make them run in real time. both xbox and ps5 use hardware RT acceleration off of the direct X API software

What has changed? Aren't these are all features we knew about yesterday

The only thing that seems new is infinity cache which neither system seems to have

Seems like co-branding goes along way

So the Xbox series X has full hardware support but not all hardware support what the hell are you talking about?

You just need to separate architecture improvements under the hood (clock-gating, new data paths, infinity cache etc) from new features (RT, Mesh shaders, Sampler feedback, DirectStorage integration, VRS etc).

What MS is saying is that Xbox Series X/S are the only consoles to support all those features.

If you want to be cruel it could be as simple as Sony does not support DirectStorage (duh) since that was mentioned on the AMD slides.

The point is that it does not say anything about architectural improvements at all - that is not what the PR is about. And you can see that from the simple fact that no Xbox as infinity cache for example.

That is why the PR is slightly disingenuous since it is very easy to misinterpret.
 
Sorry but that statement is delusional lmao.
This is Greenberg tier posting.

It' infuriating that they can say that the competitor will have all of the same features but somehow not the same performance.
If Sony reveals that their die have a single megabyte of Infinity Cache this will turn out very funny.

I'm taking it there just wasn't room for it in the XSX console design. The transistor count just isn't high enough to figure in 1.5-2b CPU, the GPU and have room for a sizable additional cache.

If PS5 doesnt fully support RDNA2, then don't call it RDNA2 console trying to BS people with their custom RDNA Kind of 2.0.
