PS4 Boasts "hUMA" And Has The 3D Edge Over Xbox One

Update: We've received the following clarification from an AMD spokesperson on this story-

"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."

So, make the appropriate alterations in your head. :)

Original Story:

If you're interested in all sorts of technology, and you have a special interest in 3D tech, check this out-

According to a German publication (as translated by PSU), the PlayStation 4 utilizes hUMA (Heterogeneous Uniform Memory Access), and that supposedly gives Sony's system a significant edge over Xbox One when it comes to 3D.

This came from AMD Senior Product Marketing Manager Marc Diana. It's just a tad intricate:

"Xbox360 and older APUs have a unified RAM. This means that the RAM is no longer physically separated, but even though it's the same RAM chips, the system still distinct between memory partition for the different processors. You still need to copy the data between CPU partition and GPU partition, but this will be much more efficient than copying it between physically separated pools. But it's still too much latency for a CPU, GPU, CPU roundtrip.

PS4 will have hUMA wich means that you no longer need a distinction between CPU partition and GPU partition. Both processors can use the same pieces of data at the same time. You don't need to copy stuff and this allows for completely new algorithms that utilize CPU and GPU at the same time. This is interesting since a GPU is very strong, but extremely dumb. A CPU is extremely smart, but very weak. Since you can utilize both processors at the same time for a single task you have a system that is extremely smart and extremely strong at the same time.

I have no idea what any of that means, but Diana adds that all of this is a "game changer," so Sony is going in the right direction. The only question is whether or not 3D will be an oft-used feature on the PS4; one would assume it would be, what with all technology getting better over time, but 3D-enabled games haven't exactly exploded on the PS3.

What do you think?

I think she should divorce Anthony Weiner.

I don't see what any of that stuff has to do with the now defunct and exploded theory of 3D gaming being good but it sounds like it could help with pop-in in normal games.

Ben, maybe you should have let Beam write this one.

the only thing that i could think this has to do with 3d gaming is that you could write more efficient coding for the ps4 with the unified cpu/gpu grouping.

Errr hahahaha.

This isn't talking about 3D gaming, it just means the 3 dimensional graphics in games.

They are basically saying that the PS4 should have marginally better performance than the Xbox One.

this is talking about 3d gaming in a way that what is in the ps4 is a faster more powerful way of computing. that would translate to better 3d because the system can compute faster.

ps4 is fast and smart at the same time

xboxone is fast then smart then fast then smart...

Awww, i actually liked AC3 in 3D, especially the underground tunnels. I don't care if other people think it's dumb, i like it. BLOPS2 wasn't that great a game for me, but playing it in 3D wasn't terrible.

Fuck 3d. Everyone I know hates 3d. Sony is only FORCING it on us because they cant come up with anything else original. I say again, FUCK YOU 3d!

End of line.

Calm down son, your anti-everything opinion could be put to good skeptical use because it sounds like you might be able to argue it other than Blank Line, getting banned won't help you to do that.

At one time they said the same thing about motion control and look at what the Wii did with that and others.

what they are saying is:

pretend the cpu and the gpu are people.

in the xbox it would be 2 people working on the same thing but with their own copies of the information in separate areas. talking back and forth while working separate from each other. that is where the latency comes in and makes this slower. they have to exchange information from further away and wait for each other finish their side of the work.

in the ps4 its like having 2 people where one is smarter than the other and one is stronger than the other. now both of them have the same information but are working together to finish the work. no latency because they dont have to wait for the other one to see their work and send it back to them. the cpu is the smart boss doing all the paper work and brain work. the gpu is the dumb but hard worker busting his ass for his boss.

i did some digging.
hUMA stands for "heterogeneous Uniform Memory Access"

what it comes down to is the cpu and gpu can read and write, to and from the same bit of info at the same time. they both see what the other does in real time. it really is just this huge leap forward in teamwork for computer processing.

Hehe - now you're cute, Ben. :)
He's talking about the memory on this system, and how Graphics Processing Units (GPU) and Central Processing Units (CPU) can share the same data stored in memory, the same objects. It's nothing to do with 3D as in "the stuff we can see with 3D glasses on".

But what he's saying here is really, really interesting. It means that both the processors that just thinks out what to draw on the screen (the GPU) and the processors that thinks out all the rest (the CPU) can read the same actual data stored in memory, without having to move the data between the memory of the two processor types.

This is just incredibly clever, and further distances this console from the current high-end PCs.
It also illustrates how computing now goes from just adding raw horsepower (aka clock cycles and gpu cores) to smart design and bandwidth between the core components.

If I am reading everything correctly, and understanding it, this isn't just used for 3D gaming as in like the one you use the glasses for, actual games like Uncharted etc would greatly benefit from this.

Is this a correct analysis?

We used to get a large input from TheHighlander on these ones. Not so much anymore... or all at really.

The Highlander made his feelings well known about the PS4 when it was announced.

I still think that he's mad that he was wrong to jump to so many conclusions about the system without even giving it a fighting chance to prove him wrong.

Highlander was just as fascinated with the tech as he was the games. Now that Sony has gone from making exotic Ferraris to souped up Civics much of the PS magic is gone for him.

Free pass from me today. It's gotta get tiring for Ben to have so many always dissect everything that's written for all to see and try and poke him in the eye for it.
