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

Looks amazing yeah, but not any better than Gears 5 next gen IMO.

Shame Sony had to go down the route of €80 graphically enhanced old games rather than free 😔


Gears ain't a bad looking game but nowhere close to this for me.
it is a total remake not a remaster so it makes sense, and by the look of the views on that video, is not stopping the masses from wanting it

XSX has hardware support for i4 and i8 math that isn’t part of the RDNA 2 spec. No evidence shows PS has this.


And yes, if PS had an imaginary ML tech they don’t have, that would match what MS has. But they don’t.

Then thats not part of this rdna 2 argument then, there is much we still don't know about implementations of either, both still cagey, Sony more so but we know that's how they have been this gen.

Let's wait and see, how many time have xbox fans celebrated prematurely, ps5 didn't have ray tracing hardware at one point too.

I doubt any potential advantage worthy of investigation is overlooked by them if they wanted it, given how in such fine detail they are trying to make ps5 super efficient like cu utilisation etc. Given that path taken id wait until bragging until we know for sure.

If not and its actually a meaningful advantage then no problem saying so. But ps5 already has significant advantages that we do now about for facts.

just dropping it here to get some facts rite which ppl seems to have forgot :p

Not a great article to be honest. They didn't help build it, they paid AMD to build it for them with some input. Lets give credit where due. AMD are GPU research and development experts, and sony isn't. Doesn't mean Sony wasn't involved in some way.

Come on you just don't want to give cerny credit he deserves. He invented liquid metal, SSD, hardware IO and RDNA 2,3 and4 since 2013. Just you wait until the rdna4 nda is up and he can talk about the PS5 SOC!

it is easy, AMD said that xbseries will be pinnacle of innovation when it launches, yesterdays blog post from ms specifically says that ms decided to wait for AMD to finalise their rdna2 before ms finalised their architecture for xbseries, then we have got lots of ms studio games announced that will probably start launching late 2021 and roll from this point onward. This suggests couple things, that that wait for AMD caused Xbox architecture to be finalised later than Sony, but also resulted in Sony missing out on some rdna2 features (making ps5 not a “full” rdna2 platform), question is, how will these missing features impact ps5 games?

if ms states that they have waited for rdna2 to be finalised, they suggest that Sony didn’t want to wait, and depending on what these features are, long term ps5 might not be able to deliver some stuff possible only with these missing features
Microsoft waited because that their choice. It revolves around Directx12 Ultimate. XSX for all intents and purposes is a PC. Microsoft is looking for scalability for their platforms. Whether its on PC, Xbox or xCloud.

If people actually took time to understand something, they wouldn't be coming with pieces that sound like fan fiction.

The comparison to PS5 does not make any sense IMO. Both parties would have complete knowledge about RDNA2 they then decide how and what they want their chip to be. Both can customize to their needs accordingly. Neither of them have infinity cache which play a big part on the PC. In fact PS5 is the one with something called cache scrubber on it's chip.

VRS is part of Fidelity FX

FidelityFX is a toolkit that includes these functions. Many of them only require RDNA1 and VRS requires RNDA2. If a company is using FidelityFX, then it does not mean VRS is also used if the hardware does not support it.

I agree, Sony doesnt need PC components of RDNA 2, they want to customize it and integrate it with their own console goals and purpose.

MS does need it due to unification and ease of development for both PC and XsX utilizing Direct X 12 ultimate API.

Its just different goals for Sony and MS.

sure "no games" doesn't literally mean "no games", it's open to interpretation but mine is "no games of note at/around launch that aren't already available or aren't coming to other platforms".

If Xbox Series X had 'Infinity Cache' I don't think they would be trying to balance 10GB of fast GDDR6 with 6GB of slower GDDR6.

Exactly what i was thinking yesterday, i can not understand how xbox fans think this is a win and are celebrating like there is no tomorrow.

Over what exactly

All that has happened is, they are now closer to a pc in terms or parts and architecture and Sony has changed those parts and customized it with their very own versions.

The fact remains, those games from ubisoft show parity in settings and modes at 120fps, 4ketc, ps5 with 10 Tflops is matching a 12 tflop machine, why are Xbox people celebrating this fact.?

Btw if anyone has not seen it yet there is a Nice Shinney demon souls gameplay video out a few minutes ago, its pretty spectacular.

Stop playing dumb.

There is nothing playing dumb about it, what exactly are xbox fans celebrating?

Lets hear it.

You are well aware of the blatant bullshit thats been spread about both sides to the ramp up of both these machines. This is simply a product of people claiming Xbox was somehow not RDNA 2 like Mr Tik Tok. When you have two sides throwing baseless claims about hardware that neither side has you are bound to get bit. I see most people are not "celebrating" that Xbox is RDNA 2, they are "celebrating" that once again people who claim to know things, to the shock of no one, still don't know jack shit and pull stuff from their arse.

Then you need to go back and read these posts again, cos either your not reading them correctly or purposely avoiding alot of the bits where xbox boys are stating this as a one up. Why do you think are are a dozen plus posts from people trying to explain that custom silicon is not a bad thing.

As for the tick-tock, that was a reference to the infinity cache not rdna2. And with great disappoint it looks like both consoles are not getting that, that is a bummer.

There are no fast and slow memory chips. All have the same clock speed. Therm 10gb part ist just connected with more bits. It was the only way to get higher bandwidth + 16 GB of memory without the need for even more expensive and faster chips. More memory would have been much better, but consoles are always compromises of price vs performance. And they could increase the cost more, so they chose this strange setup to maximize bandwidth at lower cost.

Post history shows all you need to know, no need to question integrity.

The xbox RDNA1 shit went left when confirmed as the "only" full RDNA2 next-gen console. Just like 9tf is an automatic ban, xbox RDNA1 should be exactly the same. An automatic ban as well.

Ps5 secret sauce, nowhere to be found "only 10 days now tick tock". All that bullshit they spread just backfired on them.

I'm pretty sure machine learning was confirmed and I believe it can just be done on an rdna2 gpu.

Yes mentioned back in that old wired article.


Vrs I believe was unofficially confirmed o know RGT mentioned it somewhere but Sony have their own methods for stuff too.



Again though with the PS5 doesn't have directML. That's a Microsoft tech, of course it doesn't have that exact version.

If Sony has PSML, haha xbox doesn't have PS machine learning, that would be a ridiculous argument no?

This isn't proof, just youtube tech channel with an obvious bias.

This is what I would call proof:

Learn the difference.
 
Again, for people who are trying to spin this as some kind of objective negative for Sony. Both Sony and Microsoft had AMDs roadmap, both had the opportunity to include the full PC Desktop feature set, the reason Microsoft basically kept their GPU in line with the PC counterpart is because Microsoft wanted ease of porting between Series X and PC.

Sony didn’t have to do this, so they simply took part of the RDNA 2 feature set they thought was most beneficial and then added in their own customizations that are exclusive to the PS5. There is no better or worse, just different.

Praying nobody gets caught out by this obvious bait
What exactly are these customizations that are equivalent to mesh shaders, machine learning silicon, vrs, and SFS? You have Sony's stated equivalent to each of these, right? Or are you just making stuff up.

*Primitive shaders are not equivalent to mesh shaders*

No idea what you’re on about mate. I was referencing someone saying Demon Souls is a simple remake that looks as good as Gears 5.
 
XSX truly is a next gen console. Can't wait till they take full advantage of all the power and features.

Yes it is. However, modifying game engines and utility libraries to fully support these new DX12U features + Velocity Architecture takes some time and a few tries I'm sure. Late 2021 games should have a pretty good support for these.

And since these DX12U features are supported by all major GPU manufacturers with their current or up coming products, these will be widely used in the future giving a clear advantage to XSX in console space.

i don’t see this as a win for anybody as we knew all the info they provided.

I see it as a giant L to those saying wait until the 28, crowd sending out the horns.

I specifically called out geordiemp geordiemp and sircaw sircaw in different threads, as they constantly referred to this date as the day of reckoning.

Now that we have seen all their reckoning, and me specifically asking either of them if they would apologize to the community, they both seem to have doubled down.

Instead of apology they continue to try to mislead people into some sort of rabbit hole that doesn’t exist.

They are the FUD they cry about.

Microsoft's Xbox™ Series S|X® is the only console that supports RDNA2's full suite of Microsoft DirectX 12 Ultimate™ API features.

Of fucking course it does. Cause Sony doesn't use DirectX API features.
They're preying on their own fanbase's crippling insecurity, and apparently it's working!! Well played Microsoft.

And you know the funniest shit here is that the Series S|X don't use infinity cache (neither does the PS5 so don't get your panties in a twist), one of RDNA2's hallmark features.
Does that make it any less RDNA2? Not really because RDNA2 is a bit more complicated than that. All GPU architectures are. Custom console architectures even moreso.

Fucking babies on this forum, I swear. Christ almighty.

So is Sony better or MS better based on this?

I need to see the math, that you obviously have.

Or are you shitting in the wind?

Yes. I am sure this will help Xbox greatly and that their many many exclusives will look much better than anything that the competition puts out. Everything is pointing that way. It's all about the RDNA2, nothing else matters 💥🤘🔥

You understand that these API features need to have hardware support as well? Meaning that these specific DX12U features are implemented in hardware level in the GPU? And these hardware features (which, BTW, are also supported by Nvidia Turing/Ampere) are then used through the API by games?

Apparently the PS5 won't have all these features implemented in the hardware level, and thus won't have all the performance increases that XSX/XSS will have.

This whole month , that was the narrative in the spec thread. "Only 10 days now, tick tock".

The show came and went and we got nothing. Instead the opposite happened. Xsx turned out the only full RDNA2 next-gen console. And they mostly ignored this thread 🤣🤣.

The new narrative is Ps5 has RDNA3 features and xsx has RDNA1 CUs lol. At some point posting bullshit as facts should have its repercussions.
 
I didn’t I was asking you. I don’t think it was that hard.
If you're asking, I don't think Sony will be better. From what I know so far, they'll have feature parity. Lower compute performance, lower texture throughput, slightly worse Raytracing performance, but a higher pixel fillrate and higher triangle throughput.

Will they have hardware VRS? I don't see why not, as it's a hardware feature for RDNA2 - one that benefits VR quite a lot I might add. It might not have the same name, but more or less the same functionality.

I'm not entirely sure what the point of this line of questioning is here, but there's your answer.

Im not going to call out the mods or how they do their jobs, but if 9.x teraflops is bannable on sight so should RDNA 1.5 IMO.

The last time they said Xbox 1.5 the 360 happened, so let them say what they want.

Like what for example?

It does not help that Sony has detailed less of the GPU customisations, but again absence of evidence is not evidence of absence. Geometry Engine enhancements (on this we have one of their ex principal engineers going on record on it too), same number of shared resources in the GPU running at a much higher frequency, cache scrubbers, but sure more needs to be unveiled. The XSX claim can be true if they integrated features helping with DX compatibility (big push from MS for a unified GDK) that does not mean all exclusive features are a massive mega performance boost (as we know have on record thanks to MS’s Andrew Goossen about SFS, the baseline for the 2.5x memory efficiency boost was raw HW capability not PRT or virtual texturing of any kind).

The games seem to be looking good, but more data is good too.

So you're saying people from XboxGAF should be ban for saying PS5 is RDNA 1.5 or not a true RDNA 2?

It is interesting as it is starting to look that Xbox will have better audio solution, better ML, more raw power, full RDNA2 and that IO speed, outside of load times might not be noticeable in games design due to MS solutions, unfortunately there will not be games at launch to showcase this, but I am guessing that from 2021 onwards next gen only games will rollout regularly from almost 30 first party studios that they have got

Them waiting on amd to finalize the architecture for RDNA2 also make sense why sdks are behind. Hence nothing at launch. This could actually turn out to be a great generation.
