PlayStation 4 May Not Feature AMD HUMA Support [UPDATE]

During a recent gamescom 2013 interview, an AMD spokesperson made inaccurate statements regarding the details of our semi-custom APU architectures. AMD will not comment on the Microsoft Xbox One and Sony PS4 memory architectures and will not speak for Microsoft, Sony or other AMD customers.

Upon asking AMD about HUMA’s implementation on either platform, i got the following reply:

Thanks for the response. Can’t go into any more details since it is up to Microsoft and Sony to talk about their products and implementations…but what I can say is that the comments coming out of gamescom were inaccurate.

AMD has their reasons for not commenting on this matter and PCPer also acknowledges that HUMA isn’t officially supported by currently available Jaguar powered chips aka Temash and Kabini which is a fact. But the possibility remains of HUMA on the semi-custom APU built by AMD. Only an official response from Sony and Microsoft can confirm whether or not their consoles utilize from... (PC, PS4, Tech, Xbox One)

But I bet people will still say that PS4 IS featuring HUMA, even the AMD itself said it will NOT.

you know the "UM" in HUMA
Stands for "unified memory" right? There was an article posted about this months ago.

"hUMA is a cache coherent system, meaning that the CPU and GPU will always see a consistent view of data in memory. If one processor makes a change then the other processor will see that changed data, even if the old value was being cached."

I remember Mark Cerny saying that both the CPU and GPU can access the same pool of memory. Thus PS4 supports "huMA".

Posted back in March

Here you read up. Microsoft probably made a fuss about it. AMD is now only saying "no comment". Sony has teamed up with AMD and other in the HSA foundation.

AMD never said they PS4 didn't support it. They said "no comment". "You should ask Sony and Microsoft on what they support." I'll give a moment to let you finish the rest of that crow you're eating now.

AMD provided the chips to both Ms and sony and it was their own (MS/Sony) design teams that came up with the layout. If it is supported in one design, it is likely supported in the other but the implementation may be different due to the factors like how the traces are laid out to the type of memory in the unified pool.

both platforms are using a unified pool of memory and their respected cpu/gpu designs are able to access that unified pool in different modes depending on the application.

That effectively means that it is up to the developers and how they create their code if both the cpu/gpu access memory at the same time or not.

We wont see any real benefits of how this works until these systems have gone through at least the first generation of titles. By then the devs will have found each platforms sweet spot to harness the power efficiently.
Maddens Raiders  +   897d ago
Muerte that's brilliant and exactly what I was thinking. AMD is not going to sink its ship with either company by coming out and flat saying this one does and this one doesn't. That's not their place, and quite frankly, they would be divulging information that only their client should be releasing to the public on this subject. We'll get confirmation of this soon enough I'm sure.

+1 for a well said comment.

edit/ @golding89 - you are one of the worst trolls I've seen here in a very long time. At this point I think you might even have Lightning beat. Keep it up, that one bubble is begging to be popped.

Nice response. Backed up with consistent messaging.
jelydonut  +   897d ago
Just because the CPU and GPU can access the same memory pool definitely does not mean that cached changes from either core can be instantly seen by the other core (HUMA). If the CPU makes a change to memory, it may reside in cache until the cache controller sees fit to store it to shared memory. The GPU will not see the change until the CPU cache controller does the write.

From a design perspective, HUMA would definitely be a advantage for pumping data to and from the CPU/GPU. Hopefully the PS4 has it, but there is no proof. And this is a case of it either having it or not. There is no software change that can create HUMA, it's pure digital logic in silicon.

Edit: I don't get the disagrees as I am stating a fact as a digital logic/silicon engineer. I never said that PS4 has or hasn't HUMA, just saying that Shared Pool != HUMA.

MasterCornholio  +   897d ago
Yep because if it wasnt true AMD would just say no and that would be the official confirmation that the PS4 doesnt have hUMA. Instead they stated that not all the information that the directive gave was correct. Which probably means that while the PS4 doesnt use the same hUMA technology as the Kabini chip it probably uses something similar which is further backed up with the bus that Mark Cerny mentions.

But heres the thing people assume that the PS4 and the XBOX One are exactly the same which isnt true. There are some technologies that the PS4 has that the XBOX One doesnt have and vice versa. In the end the most important thing is how the developers take advantage of the hardware and if one system is truly more powerful than the other that will be proven with the way games look on the console.

I wouldn't be so tied up on cache coherency. This might not even be true. We know the GPU has additional cache line control logic and a non-cacheable direct bus to RAM. Since neither GPU nor CPU can read from the other's cache, they must share data through RAM. This explicit bus basically could almost seen like "SW controlled cache coherency" IMO.

What's much more interesting, however, is how addresses are seen by either one. If CPU and GPU see the memory through a shared memory controller, than they share the same addresses. This is inherently important because an address can simply be handed over from CPU to GPU and vice versa. No data need to be copied between the two. Again, important if you e.g. create matrix arrays which you need to move with the CPU but you'd want to use GPU power to transform those which is only possible if the GPU can access this memory - otherwise latency of moving that "tiny" block costs you more than multiplying 4x4 floats. Things like this will make a huge impact. Full cache coherency isn't even required to do this.

This however, is not hUMA according to AMDs next gen design which we will see in Kaveri, which has full cache coherency between CPU and GPU - and the PS4 chip is one (or a half) generation before that.

And by having said that, I guess, that some of the Kaveri design made it into the PS4 chip - e.g. mem controller probably (it differs from other APUs because those can max address 2GB through a "PCIe" like "virtual" interface) and with it shared address spaces.

The XBone has a complete different memory setup mainly because how it implements and depends on eSRAM. I doubt if there is any address sharing there - or maybe there is. I just doubt it, but have no idea. More like an educated guess.

Eventually we'll find out. The truth always comes out.

NewMonday  +   896d ago

the XB1 dosn't have hUMA because it doesn't have unified memory, it is split into DDR3 and ESRAM.
JsonHenry  +   896d ago

Kabini doesn't support huMA. Both systems have a kabini GPU in them. You do the math. Unless that "semi" part of the "semi-custom" was specifically to add huMA support then I doubt the system will be supporting huMA.
NewMonday  +   896d ago

non of them are Kabini, they may be equivalents but they are both custom designed, they are not "off the shelf" like some like to say, they need a specific manufacturing process, they just use standard architecture .

some of the customization are the increased ques and cache bypass on the PS4 and move engines on the XB1.

and like Muerte2494 said, Cerny described the same process as hUMA working on the PS4, maybe it's just they can't call it that.

Thank god Meurte2494 you are living proof that other humans can use simple logic and reasoning to work things out :) well done :D (I'm not being patronising if that's how it sounds sorry) the whole thing is rediculous the only reason theyve had to withdraw previous comments is bwcuas MS are partners and they can't be seen to promote one console over the other. However on the whole AMD have said several thinfs I've been surprised MS let go I mean if I were them I'd be pissed off tbh. True or not the "ps4 our most powerful APU" comments among others must have ruffled some feathers.
darthv72  +   896d ago
@newmonday you do know the ESRAM is not really RAM in the same sense right?

think of it as 32mb of Cache or a 32mb buffer. The rest of the memory in the system is unified just like in the 360.
H0RSE  +   896d ago

But Xbox does have it...
"The AMD chips inside the PlayStation 4 and Xbox One take advantage of something called Heterogeneous Unified Memory Access (HUMA), which allows both the CPU and GPU to share the same memory pool instead of having to copy data from one before the other can use it."
"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. "

It seems Xbox One has the same features, they just don't call it hUMA due to the extend of customization of the chip.
JoGam  +   896d ago
AMAZING response.
NewMonday  +   896d ago

- the Idea of hUMA is for the CPU and GPU to read data with fewr re-writes, I can't figure how the ESRAM setup works with this

- the XB1 DDR3 ram is one block but it is still partitioned between CPU and GPU like the usual conventional method, tasks don't need to be split like on the PS3, but just like on the PC re-writes are needed between CPU and GPU, so no hUMA.

Unified memory doesn't exactly mean that it is using hUMA. The Xbox One also has unified memory architecture.

It's actually easier to program from a unified read/write pool. That is true, However I must point out that the Xbox one eDRAM can only be used by the GPU. It's pretty safe to say that Sony's custom GPU is using hUMA, and I believe that's where the PR word "Supercharged PC" comes from cause this wont be out on desktop PCs until next year!

they did not day such a thing, where did AMD confirm the PS4 does not contain Huma? no where, AMD did not retract anything.

so i claim i get a response from AMD and that is somehow, more credit worthy information than a freaking named, interviewed Sr. Product Manager AMD employee?

first off here was what was stated:

"Upon asking AMD about HUMA’s implementation on either platform, i got the following reply:

at least the orig. news source gave out a freaking AMD product manager name and it was in an interview, and AMD yet confirmed it was an interview out at gamescom.

"HUMA isn’t officially supported by currently available Jaguar powered chips aka Temash and Kabini which is a fact."

and the fact is these are not just a off the shelf Temash, And Kabini processor's that are in PC's they are custom made and tweaked.

Nice, they mention the PS4 specifically while stating no other chips will feature this till 2014.

"The arrival of HSA is still some way off, with the first AMD chips set to use the architecture expected to arrive early next year. However, the PlayStation 4 is expected to feature an HSA type processor, so we'll see some indication of what we can look forward to when that console arrives in Q4 this year"

That's all the validation I need, lol.

you're naive in thinking that AMD aren't calling marc diana's statements "inaccurate" as a form of damage control.

just like how phil harrison's comments after the xbone reveal about the used game fee was "inaccurate" (even though, at the time - before they flipflopped - it was true). in fact, they were so "inaccurate" that he called in the journalist twice to further explain the way it was going to work, and those statements were only "inaccurate" as a form of damage control as a result of the outrage people had towards that kind of policy.

The Xbox 360 actually used a similar architecture but instead of using eSRAM it used 10MB eDRAM for the "daughter die".

Dang it... so disappointing to hear. I love HUMAS... totally would love these consoles to come with as well as a few triscuits.
BattleTorn  +   897d ago
Yo, triscuits are overpriced, wheat thins are 50% more powerful! :P

saber00005  +   897d ago
Listen guys. Microsoft complained to AMD about the comment being made about the PS4 being more powerful. Since AMD is partnered with BOTH companies, they are NOT liable to say what is better. Of course they will go back and not comment. But as for the rumor of HUMA not going to be out for the PS4, it's simply not true. AMD works closely with BOTH companies to make the game consoles. They know the ins and outs. AMD is reframed from talking about what is better since both Microsoft and Sony are their clients. You don't talk crap about your client's products.

Wait...they just said that ITS A FACT that the jaguar chips don't support also the chips that power both next gen unless these chips were custom made to support huMA how would you expect it to work if the chips themselves don't support the feature...unless you guys are MAKE the ps4 have it an the xbox not....
quenomamen  +   897d ago
And the chips in the PS4 are custom made, they are not off the shelf Jaguar chips.
riseer23  +   897d ago
These Jaguar chips are custom,the fact that Sony added a Bus to help out with a bottleneck tells you it's not the same as a standard Jaguar chip.

There's overwhelming proof in support of the original interview.

Sorry it hurts bots....really.
BattleTorn  +   897d ago
That's some strong fanboy logic there.

An official "no it's not" as overwhelming proof that "yes it is"...

How can you take what their saying 'isn't the case' as overwhelming proof towards what their NOT saying, and thus in fact 'is the case'?

If you read the article it quotes an AMD source saying PS4 does use it. We can all safely assume it does.

The XB1 may not use it. Therefore the PS4 will have some extra source on top like we all suspect it does.

Lets see what developers do with both consoles. They are both way above current gen so we can all enjoy the benefits. Microsoft will have the snazzy OS's and software integration and the hardware giant Sony will have the edge on grunt.

Nothing here we all do not know. Let the Games begin..

Who cares if it has huma or not. It doesn't make up for an outdated gpu and severely outdated 1.6ghz cpu. It can't even render hi res textures in cod ghosts for crying out loud

But hey, huma.
windblowsagain  +   897d ago

Or how about the best version of NEED4SPEED.

PS4'S GPU is about as fast as a 580gtx. That's good enough for 1080p.

CPU in PS4 is slightly faster then a i5 2500k.

It will plenty PC games maxed. Simples.

jlo, da hell are you on about. COD - ROFL.
jlo  +   897d ago
Exactly, 'COD ROFL'... and the PS4 can't even render the high res textures for this ROFL game

What a beast!
Whitey2k  +   897d ago
Actually the gpu us faster then a 580gtx and the ps4 gpu is just equivalent to a 660ti considering the cores of a 580gtx is 512 I think!
Pain_Killer  +   897d ago
BF4 PS4 60FPS 64PLAYERS? Yeah on 720P

Or how about the best version of NEED4SPEED? Out of the consoles, sure. But nothing even comparable to what the game would be on the PC.

PS4'S GPU is about as fast as a 580gtx. That's good enough for 1080p? Haha, Keep on imagining the GPU being faster than a GTX 580. Its performance is lower than the Radeon HD 7870 due to lower clock frequencies. You expect AMD to put a 1000 MHz GPU clock speed onboard the APU die? That's hardly possible even if it is a semi custom chip.

CPU in PS4 is slightly faster then a i5 2500k?

What? Seriously what? AMD's FX-8350 which is the top tier x86 Piledriver chip has hard time keeping up with the i5 2500K and you think a low power Jaguar based chip is faster than the 2500K? lol dude, you gotta try hard

It will plenty PC games maxed. Simples. Your grammar makes me laugh. Simples.. lol.. first tell Sony to max out their own exclusive titles such as Killzone which can't even do 60 FPS.

FrigidDARKNESS  +   897d ago
AMD retracted that statement made by the AMD staff member. You Sony guys should do research on Huma and learn about the ps4 technology.. Like i said the ps4 architecture never designed to support Huma with the off the shelf pc components from AMD.
ziggurcat  +   897d ago
retracted for the purposes of damage control, which doesn't take away from the fact that a senior staff member confirmed it does have huma.

prove that PS4 has "off the shelf" components.

starchild  +   897d ago
You Sony fanboys are f-en morons. You claim that AMD said the earlier statements by an AMD representative were false simply for damage control or because Microsoft paid them. Yet you have ZERO proof of that. Zero.

Not only are you delusional tin-foil hat-wearing morons for coming up with such an absurd claim with zero proof, but you also are too dumb to realize that people could just as easily claim that Sony paid the AMD rep to make those comments in the first place.

Neither scenario makes a damn bit of sense, though. What clearly happened is that the AMD rep misspoke or his comments were misinterpreted by the journalist that did the interview. Thus AMD saw that misinformation was being spread in their name and they felt the need to step forward and set the record straight.

"Of course it wont its architecture never supported it."

really: So now developer's even for the xboxone are now saying that it does support it, and that the XBOXONE SUPPORTS SOMETHING like Huma but not the same thing!


June 21, 2013

"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. " -->hUMA is AMD's definition of a unified memory implementation with certain features. It seems Xbox One has the same features implemented but they just don't call it hUMA due to the extend of customization of the chip.


"The AMD chips inside the PlayStation 4 and Xbox One take advantage of something called Heterogeneous Unified Memory Access (HUMA) " 2488/amd-sparks-x86-transition - for-next-gen-game-consoles


Not all game developers license game engines from other companies, though, and AMD's Marc Diana says those engines aren't as efficient as could be. "The publishers still had to take their time and decide, do they really want to launch on the PC?" Diana said. "I don't think they have to answer that question anymore."

So which is there sparky? Huh, is Microsoft's xboxone developer now not telling the truth?

How about Marc, who is from AMD?

Here is a hint the cats out of the bag, since june to now the xboxone for its design choice does not have Huma built in, and the PS4 does, just like the XBXONE has HDMI in /out while the PS4 only has HDMI out.

The PS4 can have something in its hardware that the xboxone does not have right? or is that to far fetched?

"The AMD chips inside the PlayStation 4 and Xbox One take advantage of something called Heterogeneous Unified Memory Access (HUMA), Good for gaming, good for AMD which allows both the CPU and GPU to share the same memory pool instead of having to copy data from one before the other can use it."

Or maybe they can both have it and everyone can move on right? Why is this such a big deal anyways? If they both have it and they both do the samething no matter what it's called then who cares.

Ulf  +   897d ago
I would actually be MORE surprised if the PS4 supported hUMA, than the XB1. The original Kaveri/Jaguar design supports hUMA with DDR3 on laptops, after all -- it comes for free with the basic design.

Sony would have to pay extra for the GDDR5 unified interface design.. maybe they did, I dunno. But in any case, its almost certain that the XB1 has it. The PS4, with its GPU-oriented memory setup, is the one that deviates from standard AMD laptop setups, and really seems like it would be the one in question.

They could easily have been payed by MS to not comment. The only way to withdraw a claim is say it was wrong.
