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

PS5 has RDNA2. It might not have a feature or two that Sony decided they didn’t need or came up with they own implementation.
First off we don't know if Sony has their own implementations. Digital Foundry has went on record that Sony has refused to answer if they have SFS, VRS, etc... equivalents.

Secondly even if Sony has custom implementations that doesn't mean they will be as good/performant as what MS and AMD were able to come up with.

If Sony's implementations were better AMD would be using those solutions on PC (Mark Cerny mentioned this himself) which AMD is not. So that should give you a clue.

Fear Uncertainty and Doubt. The XSX has hardware based ray-tracing


he dual compute units (DCU) of the Big Navi-like GPU inside the Xbox Series X do have specific hardware dedicated to accelerating the real-time ray tracing process. But that seems to be the only change to the RDNA 2.0 dual compute unit compared with the first-gen ones found in the AMD RX 5700-series cards.

Well if part of the featureset is anything to do with DirectX its obvious that Sony have no need for it given they have their own API. Really not a fan of how MS tries to brand every aspect of its technology, its understandable in the context of the wider PC space I guess but its really not helpful when comparing with technologies outside of that sphere.

so i still dnt know what this means, and on top of it all, why this announcement now? Wasn't this known before? wtf is happening

AMD just announced their RDNA2 GPUs.
So naturally Microsoft was now allowed to talk about what the full feature set of RDNA2 actually is after AMD showed it off.

Basically AMD put an embargo on MS in regards to talking about RDNA2 features.

I was hoping AMD would demo it today but I guess we are gonna have to wait for that down the line.

Well, Sony is using a customized RDNA2 chip, which actually if you think that's a plus for sony, why would they get out of their way to create extra functions when they could have used the stock RDNA2.

It's gonna be an interesting battle, probably multiplats will be better at launch on xsx then when devs use the specific functions sony created things will be different. Exclusives certainly will take advantage of the custom functions sony baked in.

Sony always did that, on ps4 it was the same.

I don't think it has to, but fanboys gonna be fanboys.

We don't know PS5's approach to RT. We don't know what custom features are there. We don't know what custom hardware is there apart from the fast I/O. What we do know from multiple sources is that the PS5 is easier to develop for and no dev seems to feel concerned about it, while the same can't be said about XB GDK.

That the XSX is stronger based on the hardware has never been in question IMO, the real question is just by how much, and judged from multiple sources as well, the difference has never been so narrow. 🤷‍♂️
We DO know PS5's approach to RT, this was discussed long time ago in "the road to PS5" Cerny talk. He said FLAT-OUT that their RT implementation is the same as AMD. (i.e. RDNA2)

Because "full" is not a good or bad thing. If sony took one RNDA2 feature that used 5m^2 die space and gave a potential 15% improvement and replaced it with something not part of RNDA2 that was 5mm^2 and gave a potential 30% improvement, then what decision should they make?

RDNA2 feature set is AMD stand alone PC GPU featureset. If you want a PC, buy a PC.


Some of you guys completely miss the point. Both consoles will mostly have parity besides maybe one with a better framerate or higher res or even better rt.

The point is the majority of people have been in the spec thread saying Xbox is RDNA 1.5 and that apparently today some secret sauce for ps5 would be unveiled.

The opposite happened. What was already known to everyone besides some fanboys was confirmed. Xbox is RDNA2 and no Ps5 secret sauce.

Guys are way too bent out of shape over this. The ones who were wrong just admit it and move on.

Like I mentioned in the past full RNDA2 is going to create an even larger difference between the consoles than just the raw performance difference between the two consoles.

I can easily see a performance difference between the systems going above 25% and even up to 35% when you add up the raw performance and features set of RDNA2 down the line in a year or two when developers start properly optimizing for the Series X.

This is a significant boost for the Series X|S that will become more and more evident the deeper we get into the generation. Get ready to see a lot of Dynamic vs. Native games just like with the Pro vs X from this generation.

In terms of specifics, using Direct X API and having features sure it's full RDNA2. Not really arguable and nobody should argue it. Both are RDNA2 though. This narrative one isn't and one is, is just silly. They both clearly adhere to the AMD roadmap in their own ways. But to be fair, if a feature isn't missing. Well it can be built in house, it just won't have the same name. The same way other APIs can be used in place of the other. Both are custom with their own end game, nothing more, nothing less.

This being spun into clickbait and console waring is dumb.

All hail those accelerated 4bit/8bit tops, will probably be the most important addition to RDNA2 GPUs.

Well that's all you had to say, so it is software based but has a dedicated hardware to accelerate it, so no cost.
👍


All RT has a performance cost. Hardware typically only does the calculations of the rays themselves (Raymarching IIRC)

Those rays have to be shaded, which is done via traditional rasterization.

Yeah but what about the DGPU?

Well I assume it's good in one aspect as software can be updated?

Wrong about what? The only people that are wrong are those saying either console is not RDNA2. Both were designed at the same time and had a menu of features that AMD was designing for their PC GPU. From there they deviated in design. That is what we have today, two similar but different designs. The two APUs are siblings, same mom, different dads. It's a little sad that MS plays into the public's ignorance, adding to the console war mentality.

Fuck me. I'm glad on days like this I'm not overly tech minded and just wanna play games like a kid again.


I feel the same but when launch lineups are as weak as they are now. We have retards slinging mud at each other over everything but the games. These guy were warring over the cardboard packaging for cry out fuckin loud..... CARDBOARD PACKAGING.... let that sink in lol

This is interesting, it remains to seen exactly what customizations Sony made but Series S/X are the only fully RDNA 2 next gen consoles. This doesn’t mean the PS5 is inferior since we don’t really know much about it’s customizations. Could had been a timing thing, since Sony started earlier with their next gen console production and was ahead of MS. Maybe they had to cut down on the costs to match Series X, so maybe they research their in house options and came up with cheaper solutions. Or maybe it just fits their philosophy and console design better. Who knows though, both consoles have me excited.

But yea a lot of members were harassed about this. Should be an interesting thread.

Isn’t this old news? GAF has been telling us for months that PS5 doesnt support all RDNA2 features.




It’s more like RDNA 3

FTFY.

Wrong about Xbox being RDNA 1.5

Guys only have an issue with calling out "fud" on their console of choice. I bet you, one moron tweets "Xbox tf are gcn not RDNA2" and some morons will believe it without question.

Idk what any of this means I just want to know if multi platform will be better on one console or another

Sony have said nothing about ML support if thats not part of the feature set they thought they needed, this is gonna be a long generation for them.
You are going to build in DirectML abilities after the fact from scratch and expect it to run in real time?
Alright.

Yeah. I'll always remember the day several hundred £ consoles were slated and argued over because of the £2.50 packaging. Gotta love this place :messenger_grinning_squinting:

There is something fishy happening in that PR.

If you looks at the SoC pics the Series X clearly lacks Infinite Cache that is one of the new hardware features in RDNA 2.
So it is not full RDNA 2 hardware.

RDNA 2 features Infinite Cache.
Xbox Series X hardware doesn't have Infinite Cache.

So Xbox Series X doesn't have full RDNA 2 hardware.

What's FUD?

it's a tactic used in marketing, politics, propaganda etc... basically pushing disinformation to put a competitor at a disadvantage while appealing to others sense of fear. it's not always done intentionally (like in your case when you said XSX has software based RT (it doesnt)).
