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

Copy what I said in the Duplicate thread...

Nice! we will probably only see a difference in first party games late gen though.

and why again did microsoft go with amd? but for those that pretty much are ignoring what the o.p. said i will try to explain it. microsoft didnt need to go with huma to do tiled resources because it was made for tiled resources. it all has direct x11.2 to get it done.

http://www.vg247.com/2013/06/27/microsoft-debuts-new-tiled-resources-graphics-tech/

hUMA isn't about tiled resources.

MS' "tiled resources" tech is already being used. It isn't MS exclusive. All it does is keep the high quality of whatever the camera is pointing at. This isn't an advantage for the One.

hUMA is about the CPU and GPU using the same pool of memory and being able to read each others data without the data having to be copied back and forth between the CPU memory and GPU memory. Tiled resources is software that is being used now, but just might not be called tiled resources. They show the same tech in COD Ghosts, a multiplat game.

in the op we get this

Back in April, AMD manager Phil Rogers explained to c't that hUMA improves 3D-performance in particular. "Game developers have been eager to use very large textures for years. Until now they had to resort to tricks in order to package parts of larger textures into smaller textures. That is because today a texture has to be located in a special place of physical memory before the GPU can process it. With hUMA, applications can work with textures much more efficiently"

sounds like tr to me, no?


No not at all. Did you read the link I posted?

tiled resources has nothing to do with data communication between CPU and GPU, hUMA is all about that. Tiles resources is about saving resources by lowering the quality of everything the camera is not pointing at. You can use tiled resources with a hUMA archetechture.

@bolded: Suggests it does more than what he is talking about.

Lol msft supported Amd for so long and now they fuck with them

It's about creating new algorythms and totally rethink the way we compute 3D.

Of course you won't see it in early life of the consoles.

Like the difference of bandwith on RAM.

This is AMD selling its products.
It´s the same thing with Nvidia pushing their Physx processing or the anciante 360´s Tesselation.
They are just sets of H/S fuctions that are suposed to improve performance in a way or another.


.......uh the One's apu is also their product


Not exactly. Microsoft spent a lot hell of money customising the APU, for any reason they didn´t want to implement  hUMA, may be they using a better or simpler (or cheaper) solution.

He was pushing the hUMA tech, this is a big selling point of AMD´s APUs. So, no suprise he praised PS4 for using a regular AMD solution.


Are you really trying to imply that Sony didn't spend a crap ton of money customising the APU? I don't want to come off as a deuche, but your comment is laughable.

If MS came up with a better solution, why isn't MS or AMD touting it? Why isn't AMD putting that solutin in all of their apu's?

How loud do I have to say this; XBOX ONE CONTAINS AN AMD APU. Its a custom apu, just like the PS4 contains a CUSTOM AMD APU. So why would AMD have any reason to say one is better than the other, unless its true?

LOL at regular AMD solution. PS4 contains the 1st AMD apu with hUMA, but its a regular AMD solution? Flawed logic much?

They certainly wont go back to nvidia anyway. Where else do they have to turn really?

They also said that Xbox 360 can't do 3D at all having HDMI 1.2 and 3D needing HDMI 1.4 ...yet here we are.

I know this refers to 3D game models and stuff...but Microsoft will find a software solution if its a dealbreaker.

AMD is saying this to push their own upcoming products which feature hUMA.

I wonder what the real world advantage will be? Nicer textures? Or high-res textures that load faster? Or just an overall performance advantage because dealing with textures will be more efficient? I can't tell for sure from the article.

Ah, wait, the link has more:

"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."

and an explanation from another user:

"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.

It will allow for an extreme boost for many, many algorithms and parts of algorithms. On top of that it will allow for completely new classes of algorithms. This is a game changer."

Interesting stuff. I wonder how much of an effect we'll see.

Why not? Nvidia was the chosen partner for Microsoft Surface and upcoming Surface 2 (RT models).

They would go back to Nvidia in a flash if they had a competitive x86 solution. Nvidia doesn't do x86 but GPUs and ARM SoC.
