Forums - Gaming - AMD: PS4 performance advantage over XB1 bigger than many expect thanks to hUMA

Fail lol :)

It is actually the opposite, people who are developping for both console says that.
The internet, on the other hand, states that the PS4 is an half-god

And this one is another great internet story from NeoGAF :) AMD did not say "PS4 performance advantage over XB1 bigger than many expect thanks to hUMA" like the title of this thread suggests... It is the internet who, again, extrapolated and as always the Playstation fans are jumping on it :) (but they do not believe developpers who are actually developping for these consoles.... so funny)

According to the original article, what the actual video game developers developing for both consoles said was actually even worse than what the AMD spokesperson said, suggesting that PS4's 3D performance is "very far ahead".

And this is not just some fanboys on the internet telling crap. c't magazine is by far germany's most respected computer technology magazine. They're not fanboys of any console either, they're actually hardly reporting about video game consoles at all. There's just no reason why they should lie about the video game developers saying that PS4 performance is clearly ahead.

But it's somewhat interesting that these video game developers apparantly wanted to stay anonymous. Seeing AMD's immediate reaction to Microsoft's pressure though, I guess it makes sense.

I think some people fail to understand what exactly is going on with this. The APU in the One is made by AMD. It is not MS' tech, it is AMD's. MS' apu was not built MS. MS had AMD make a custom apu. This is exactly the same thing Sony did. MS does not have HUMA or anything similar. Either you have it or you don't. There is no in between. You can't sort of have heterogeneous unified memory access. This isn't software. It isn't just hardware. It is a different approach to computing. A more efficient way that allows CPU and GPU to cancel each others bottlenecks out. With current architecture you have to communicate with the CPU and GPU seperately. When data needs to get passed between the two, it has to be copied. HUMA eliminates that so one algorithm can communicate with CPU and GPU at the same time. Impossible without HUMA.


Thank you!  Someone else here actually knows what he is talking about!


Yeah it took me all of 15 minutes to read up on hUMA and the differeneces between that and Ones archetechture to figure it out. I had no clue what hUMA was before that. All I knew was that the PS4 had it and AMD was going to start putting it in PCs. The rest was just common sense and logic.

PS4 performance is not "very far ahead" because the hUMA... the PS4 have everything more POWERFUL than Xbone... only the CPU is on pair... everything else is better on PS4.

We can discuss here if the PS4's RAM POWER will show in games but that PS4 performance is better is a common fact already.

I guess yosp agrees with AMD.

Or with the previos question:  The emoticon is a recent boom?? (Lol)
As translated.

I don't even understand what you are meaning. Sorry.

You have software, code, in hardware.  If you think otherwise you're fooling yourself.  Both GPUs and CPUs have code associated with them that determines how they operate.  Microsoft or AMD could easily alter AMD's hUMA for Microsft's specific needs.  Hell, that's one of the reasons why Microsoft went with AMD in Gen7 for their GPU.  AMD would customize the processor based on their needs. 

Nothing you've said can substantially contradict what Microsoft has stated nor that the Xbox One APU doesn't have hUMA.  The development documentation states it.  Microsoft's Marc Whitten has said it.  So who are you to contradict it?  Because a guy from AMD who may not be aware of the design of Microsoft's APU?  Is there the distinct possbility that Microsoft may have a NDA agreement with AMD where AMD can't reveal any details about the APU before launch?  Which might just justify why AMD made a retraction with no comment instead of elaborating?  Seems entirely logical to me.

Not to mention, AMD just retracted their statements for being inaccurate. 

But the Sony fanboys will just say MS paid them since they say that to anything.

Whoops, double post.

AMD retracted their statements for being inaccurate! Xbox One has same/similar hUMA tech so can we put this thread to rest now?

No I do research, Which you obviously don't. I read up to try to understand the situation, you take what some talking head says as fact and run with it. There's a big difference there. HUMA is a hardware solution that can change the way you code. You can still code the classic way, but hUMA allows a new way previously impossible.

There are plenty of articles out there stating exactly what hUMA is, and what it means for computing, not just gaming. Please read some before you tell me I'm fooling myself. It is impossible for MS to have hUMA because of the archetecture they chose. They cannot implement it at a later time.

You can believe MS if you want, but I believe facts and science before talking heads.

The name is not a marketing word.  As someone who actually understands these things, I can say hUMA is a pretty big deal that could increase performance by a ton.  

Also I am tired of this "MS said this" crap to.  Everything MS has said in the past half a year has either been changed, retracted, or proven to be total BS (Teh CLOUD).  Of course they say they have something similar!

I'm sorry.  Microsoft talked about coherency back at the Xbox One reveal in May.  They had an architectural panel where Nick Baker, the main hardware engineer for Xbox, explains that they're using it.

Do you think they just can yank that out?
