    Quote of PR Lead for Gaming and Enthusiast Graphics at AMD Robert Hallock:

    “People often compare the hardware of the next-gen consoles and the PC, compare specs on paper, and conclude that these consoles must be “PCs in a box.” That is patently untrue. While there are many commonalities, there were platform architecture decisions made for the consoles that set them apart from the PC in a significant way: how developers access the hardware, the Xbox One’s ESRAM, and the PlayStation 4’s UMA are all powerful examples of such decisions." ~Source

    AMD must be tired of playing Switzerland and must really want to tout the new tech they've developed

    doesn't that make him the second PR guy to leak that?

    No one ever denied UMA.

    It seems it could be pointing at Xbone not having a Unified Memory Architecture. People were still debating over whether Xbone could have UMA with the eSRAM setup. The way this was stated, it seems he may be implying that Xbone doesn't have UMA.

    The Xbox one doesn't have UMA, it had UMA last gen.

    Lats gen it was UMA+EDRAM Cache

    This gen the EDRAM is fully addressable. Which means it is a a hell of a lot more flexible.
    UMA aint anything particularly exciting. Its just makes that memory flexible.
    Your not strictly limiting what memory is used for which purpose.

    i.e. 512mb on the PS3 is strictly 256mb CPU, 256mb VRAM (there are some shairng but its has drawbacks).

    The 360 was 512mb for what ever you wanted, ie. 128mb cpu, 384mb GPU.
    People were still debating over whether Xbone could have UMA with the eSRAM setup. The way this was stated, it seems he may be implying that Xbone doesn't have UMA.
    The Xbox one still has UMA on the main memory PLus it has a non-UMA memory for the GPU of 32mb.

    You could still have HUMA on the 8gb memory no problems at all.

    I doubt if it would be available on the esram though.

    HUMA isnt really about the memory its about being able to pass pointers to "a particular memory" spot, and have it addressable by both CPU and GPU.

    It doesnt mean you cant have both HUMA and non HUMA memory.
    And neither is specifically linked to UMA.

    Now officially debunked by MS.



    One unique aspect of the chip is a shared memory pool that can be accessed by CPUs, GPUs and other processors in the system. Typically, GPUs and CPUs have different memory systems, but the new features increase the overall addressable memory in the Xbox One. The GPUs and CPUs have also been modified to enable shared memory.......
    "An important aspect of that is letting CPU and GPU share memory spaces," Sell said.

    So essentially both consoles will be able to process to a similar result. They take different paths but get to the same end point.

    Actually their paths are almost identical.

    Well that's good to know. Any idea if the One will be difficult to program for like the Cell was/is.

    More specifically, hUMA includes the ability for both a CPU and GPU to use the same pointer value to access the same object, WHICH ITSELF MAY CONTAIN POINTERS. Simply moving the object will invalidate the internal pointers. A fast hardware copy from CPU space to GPU space (or vise versa) is not good enough.

    I guess everyone miss the arrow running from the cpu to the esram on the x1 slide.

    I saw it, i'm just not sure what it means. I assume it means you write from esram to the cache coherent cpu cache. Which is pretty awesome as well.

    The proof will be in the year 2 games and onward. To be honest I put more stock in the talents of SCEWWS more than I do any kind of wizard $#@! hummus...Looking what ND, QD (not FP I know) and SSM have accomplished on PS3, and knowing that info is shared within WWS, Ill big up the workers, not their tools. Though PS4 is looking to be a badass tool.

    HUMA or more specifically HSA is very much the way forward. It more tightly integrates the data in the memory. And is essential for compute to work efficiently.

    With out it Ghost, all that extra teraflops in the compute side of the PS4 would be very much hindered and inefficient.
    Its one of those reasons Naughty dog will be able to extend the work they did with SPU'S.

    After sighing about the arguing going on in this thread, I started thinking of this comic I made

    How the $#@! did this discussion remind you of your comic?

    You don't get it? Guess you can't read between the lines.

    I know this is a forum full of "nerds" and all (maybe some with aspberger and lack of humour or w/e), who are here to discuss gaming and gaming technology, but still.

    So, now the PS4 has a kind of beta implementation of hUMA and the XBone has... what does it have?
