Xbox One (Durango) Technical hardware investigation

There's a problem in how the information has been run through the filter of the writer's interpretation of the comments of the AMD PR rep, then further filtered by a translation from (English/?)German/English and finally filtered by my own understanding. Having said that, it looks like the writer is taking disparate information and drawing a conclusion.

AMD has said that hUMA will greatly increase performance.

AMD rep said that PS4 has hUMA while XBOne does not.

Therefore, PS4 should have greatly increased performance over XBOne. This (PS4 having better performance over XBOne) is supported by statements made by developers.

I didn't read the specific article but did the AMD person ACTUALLY say that the xb1 has no Huma or was that another issue to be clarified.
 
If there is one quirk, it is that not all of the bullet points for hUMA are strictly necessary for Xbox One games. Until recently, I would have thought the same for the PS4.

The page fault and removal of the pinned memory requirement is not something the game VM would need to worry about since that memory is dedicated and kept loaded in RAM.
 
Sounds fishy. Not the fact the PS4 architecture could be more adapted to Huma ( I suspect it is, actually), but the idea of an AMD representative going out of his-her way to signal the advantage of a platefrom solution over the other...:smile:
Yes, the article flies in the face of protocol. We can't be particularly confident in it.

How high is the performance impact for full cpu/gpu cache coherence anyway. Sure it's a must for mixed code designs where you share data a lot but it doesn't come for free.
I don't think anyone knows at this point. It's an untested technology in the field.

Note, the original article is gone.
That doesn't help! Was it pulled because it's true? Or false? Pulled just means the website doesn't want to run it any more, but we don't know why. Now the cat's out fo the bag, as it were, hopefully we'll get some more investigation to clarify if there ever was a cat in the bag in the first place.

Yeah so full Huma compliance isn't needed just a subset or a functional equivalent of such. Whatever amd ip in either chip would be nda until... Whenever. Would there actually be anything amd derived Huma in either chip in anyway case?
 
Oooo a vi based gaming system! It's an efficient text editor sure but where do you put your fingers since there no home row or keyboard for that matter :D


It looks like there has been a change in the hot chips scheduling. MS presentation has been moved to the SOC session. So that is no longer a key note but is a confirmation that it is about the SOC.
 
I just read this.. what it says is:

AMDs Senior Product Marketing Manager Marc Diana told C'T that only the PS4 would have HUMA.
C'T then speculates that it will result in a even bigger performance gap vs the XB1.
There is no quote but they claim they were told so by Marc Diana.

C'T then adds that behind the scenes they heard unofficial words from developers that the PS4 was far ahead in 3D performance vs the XB1

Unfinished hardware/software tools? because what we have seen is not representative of that statement.

Huma or a specific subset of Huma functionality or... ?

Well Huma helps when it comes to compute and it would seem Sony is investing resources into that particular way of doing things so I would believe that the PS4 could be more huma-ish I don't think that the xb1 has lost it's huma-ity :rolleyes:

Not 4D? PS4 not as good as PS3 confirmed.

Posted by warchild in june from the arch panel.

Sort of been mentioned before, but i wanted to point out that alot of the technologies we have to go and investigate on the hardware really belong in a data center. So with 64 bit processors we need to support hardware virtualization to be able to have multiple operating systems, we have to invest a lot in coherency throughout the chip, so there's been io coherency for a while but we really wanted to get the software out of the mode of managing caches and put in hardware coherency for the first time on the mass scale in the living room on the gpu.

So if the Xb1 doesn't have hUMA it has its own solution to enable coherency across durango.

Holy crap, people made a big fuss out of this. The news is everywhere. The thing is ... I read the original article and the AMD guy allegedly said that PS4 is hUMA /which is fine if true/ and then everything in the article is the opinion of the journalist.

That's what I got from the article JUST after reading it. What's the big deal? Why wouldn't Sony just publicise their memory solution and say it is hUMA from the very beginning?

Dave and AMD have hinted at the fact that someone is wrong regarding the news.

I wish we could get clarification on this, Sonygaf is running a party over there placing this as fact. Anyway, what do you think we will get out of the hotchips conference on Monday? anything noteworthy? thanks in advance?
 
I'm reading the NeoGAF post, the people are thinking that thanks to hUMA, PS4 is super powerful against Xbox One.
Can we please stop posting what GAF thinks. I personally don't give a shit what GAF thinks, any more than I care what the comments section of Eurogamer thinks, or the local pub's current population thinks, or the Milton Keynes Women's Institute thinks. The opinions who people who don't enter into a discussion on this board are irrelevant to conversations on this board except where they are referenced as part of the conversation, ideally because they are persons with something to contribute and not just some random internet identity.

Sorry, I posted because posts (and opinions) in GAF are like a snow ball, but you're right, GAF is another forum, not B3D.
 
Jeez, i didn't think this "hUMA" would be so important. maybe a bios update is the only thing standing in Microsoft's way from venturing in the direction.
 
whatever the case is, I hope we get full details at the hotchips conference. I still don't know why Microsoft hasn't detailed the GPU, even if its 600 gigaflops below the PS4. the Xbox one has shown its more than capable of delivering next gen games, actually has show more than Sony at this point. Ryse is comparable to anything on PS4.
