I think you're being overly restrictive in your interpretation. It doesn't necessarily have to be hardware disabled to not have commands issued to it. It just has a little more power overhead, which is absolutely fine given it's in a reduced performance mode with much lower clocks.

Right in the white paper is in an initialization signal sent to the wave controller for a WGP. It's not unreasonable to think that controller could be left idle and not fetch commands.

Think about it logically. Does it make sense to architect a design around a legacy support mode, including changing baseline mode performance and cost, instead of adding a simple enable signal to an instruction unit?

The Xbox One X's 44 CUs aren't a clean multiple of 12, and it supports S games all the same.

This.

well Sony even being seen as the underdog when they outsold 360 globally, suggests a US-centric world view in the reporting

They only outsold the 360 after the gen was over. Or at least it only came to light by then.

Thanks,Let me know if you find it.

To address your request: Did I make that assertion somewhere? I don't have a source for an assertion I did not make.
54 CU was my guess if it isn't 36 because of this. Makes more sense with what we know than going to 40/44/48. More expensive though (also considering it'd be 60 CU with 6 inactive), so did Sony go for it? 🤔
Chocolate covered bananas dipped in walnuts?


Was it Miniature Kaiju?

As far as I can see, there's nothing in the RDNA whitepaper that alludes to the assertion that disabling SEs is easier/less likely than SAs.
Maybe it was Miniature Kaiju, I can't really recall who it was. But let's assume for a second that it is possible to disable a single SA, even if that's the case we still have a lot of limitation to consider once your BC mode relays on SA disabling. Disabling just a WGPin real-time? That's even a larger logic leap over disabling a SA. But disabling individual WGPs will be the only way Sony will have real freedom to build whatever CU count GPU they want without a bloated die size.

Wow, those things are getting better every week....

chocolate covered banana with walnuts on it?
I wouldn't have thought about that in my dreams....
yes
Huh? Both the PS4 Pro and Xbox One X disable CUs when running games that don't have a specific profile for them. Even their boost modes disable CUs.
The pro disables a shader engine in real-time, not a shader array and not CUs. The X doesn't disable any CUs when running older games. What I was talking about works exactly like the Pro, disabling a shader engine.

Maybe it is possible to disable a single WGP just like that, in real-time on the fly, but it was never done before including on the PS4 Pro which was designed around legacy support, exactly what you say is illogical :)

Regarding the Xbox One X BC as an example, it doesn't disable any CUs in order to support S games, it uses a completely different method (it does have cut performance by almost half). I wouldn't use MS as an example considering they handle BC mostly by their thick abstraction layer and they don't care how many CUs are running under the hood.

Disabling at the SE level makes sense because that's how Navi 10 is portioned out. As I pointed out above, Xbox One X supports S games despite not having an integer multiple of CUs (44/12). For that matter, Xbox Series X likely won't have an integer multiple of either of them, yet we've just been taking BC for granted there.

different approach for MS BC though - if they have more of an abstraction later then maybe they're less sensitive to CU/GPU configuration?

How much did the PS3 sell in it first month and then first year?
I remember that it didn't sell that well within the first months to year in The Netherlands. Some shops still had their Day One consoles even after the holidays where over.

The point is that there are multiple ways to accomplish the end goal, and a patent application isn't binding or all encompassing. To suggest that they'd change their whole GPU structure just to support BC mode is asinine. Imagine hampering the performance of a console just to support BC. What they did on PS3 is take out BC instead to cut costs.

As informative as they can be, many patents become visible after a technology has been deployed to the market. The BC patents describe many of the ways the Pro does it. There's nothing stopping them from evolving that approach which will get future disclosures.

what assumptions are being made in the speculation for chip layout? If 3 SEs mean too much die size, are people assuming 2 for series x? If that is 56CU as speculated, does it have other negatives like less efficient utilisation having 28CUs Per SE?

For that matter, Xbox Series X likely won't have an integer multiple of either of them, yet we've just been taking BC for granted there.
a) Xbox uses hypervisor/VM provisioning which is a SW approach.
b) The way it works on the X is similar to what Sony is doing on HW but on that SW level. Nothing will be disabled or enabled on the hw. It all works by resource provisioning.

regarding b):
The One GPU consists of 2 SE with each 6 CUs in it. The One X consists of 4 SE and 10 CUs per SE.
What One X does in regard of BC for Xbox One games is that the Game VM gets a provision of one half of One X GPU.
Means: An Xbox One game gets 2 SEs with 10 CUs and full clock and thus runs at 3TF of GPU compute (documented by MS)

Speculation!!
regarding "BC is seen as a given on Xbox":
Xbox will use a similar approach on the Series X. But differently. Instead of provisioning being structured in SEs the provisioning of resources will be moved to Shader Arrays because I expect the Series X chip will have still 2 RDNA Shader Engines with 4 Shader Arrays.
A Xbox One game will get a provision of 2 Shader Arrays (each Shader Array has 7 WGPs) --> in correspondence to 2 SEs in the old console
A Xbox One X game will get a provision of all 4 Shader Arrays --> in correspondence to 4 SEs in the old console.
So in result a Xbox One Game would run now on a GPU capable of 6TF (at an assumed clock of 1675 Mhz).

Regarding memory the provisioning will be dependent on the XDK version used. Xbox One SDKs will only get 5GB of memory for the game, Xbox One X SDK games will get 9GB of memory for a game (this includes patched games).

Edit:
As this all works in software it will be even easier than what I wrote above. They may just configure a profile for Xbox One that is provisioning 1 SE for Xbox One and 2 SE for Xbox One X and Series X. That is the beauty of not being hw dependent! Simplified, you just can change the configuration profiles of the hypervisor.

As much as I want MS to lead by a huge margin, and also believe the Github leak, here is what I think to be the most reasonable prediction one can make:

Xbox Series X - 12-13TFlops: 499$
PS5 - 12-13TFlops: 499$
Xbox Series S - 4-5TFlops : 299$

Deep down we all know that both Sony and MS will have very similar specs, but the one uncertainty is the XSS being a game changer. I for one cannot wait for the reactions once it gets announced.

I wanna say March, but there's a lot of uncertainties going on in the industry right now and so part of me thinks it will be later. At the same time, I can't see the reveal being right around the release date of TLOU2, and I know many third parties like to reveal their games before E3, so I don't think it will be May. That leaves March or April. I'm gonna go ahead and say March 10th since that's actually my birthday and it would let them beat GDC by about a week.

They don't want to say a specific number because things can change.

I remember reading that, but it's not a confirmation of anything, it's just his opinion. Remember what I said about third parties having different development kits?
That's what I am talking about here. Where are his sources? Is it third party? Is it Sony's first party?

We need more information and we don't have it. Just because he said that, doesn't make it true. I am not saying that he is lying, I am saying once again that not everyone is privy to the true specifications.

You have to be specific and look how one generic sentence that doesn't really say anything calms people's nerves.

It's simply not enough to convince me.

I was talking about bananas in chocolate coating with a walnut topping.
But i always like to get some technical insight, so thanks. ;-)
I also can see that the github leak doesn't have to show the full picture,
and they were just testing BC.
I think there is a possibility for more CUs then shown in the leak.

That's all Matt was asking with that post.

Nobody said it was 15%.

Lot of insiders said they were very close, or even twins.

Matt clarified at one point that he would consider 15% close.

That doesn't mean the difference is 15%, but implies that the difference would be < 15%.
But shouldn't it be listed as "what close means" for Matt! It adds context to all the other quotes!

And you can judge "performance" from target specs of systems that have customizations, and use different OS's / etc.?

Don't get me wrong, the whole process is fascinating, and I love exploring why certain decisions are made, but the end result is really neither here nor there. One will be more powerful, and I'll purchase third party games on whatever system that is. But I will buy both of them on Day 1, and I'm sure I'll enjoy them both very much.

But, as I have stated before, since the X came out that has been my main platform (save for exclusives on PS and PC, and a fair bit of Switch as well), and, back against the wall, I expect that trend to continue for the foreseeable future.

Nintendo will never chase "power" again, but as mobile chipsets get better and better I still expect lots of beautiful and fun games to come from them.

But as you can tell by his other posts, he definitely knows the specs and is updated on the info.
Like I said, too bad he stopped posting here maybe we'd learn something new from him.

And to be clear, I don't give a damn if PS5 is stronger than XSX or not. I'm just saying the github thing some of you guys keep pushing is not what PS5 will end up being.

I think both systems will be very close, something like 11 vs 12 TF (worse case PS5 ~10.24 TF), both will have advantages and disavantages. Both will be great machines.
