    47 MByte of caches is a lot. It doesn't add up from what we know: 32 Mb eSRAM+ 4 Mbyte CPUs ... 11 MBytes for the GPU alone seems a lot.

    47 MBytes cache of cache? 32MB Esram + 4 MB CPU L2's + ??? . I doubt all the L1's amount to more than 1MB.

    I can also see something that looks like
    4x 256 bit read & write

    To me it looks like the 4 blocks underneath say 8 MB. I'm guessing the ESRAM is split into 4 banks like that.

    Audio block could have it's own dedicated memory as well, but still, not megabytes worth.

    They maybe counting some redundancy memory.

    How much sram a modern GPU/CPU has?
    Counting not just L2, L1 + registers?

    How much redundancy has AMD built?

    You beat me to this :)

    It seems to say 8mb in each block.
    So the digital foundry rumor had some truth after it after all.
    But from what i remembered df was talking about a max of 192Gb/s.

    Found an tweet on gaf.

    That 204GB/s figure is down on the ESRAM connection. I thought that was a total system measurement?

    I guess we'll have to wait for the slides. Seems everyone at Hot Chips had first-generation phone cameras.

    No you are dealing with a modern gpu that also have sram... For example a PS4 gpu has + 7 Mo of sram. jaguar has 4.7 Mo. Some other soc components have sram in the X one

    Naw. MS scotchtaped a bunch of anti-photo license plate covers onto the projection wall at the start of the conference.

    that was before the "overclock". At 853 Mhz, theorically, in both way, simultaneously,.. there's 204 GB/s

    The change from 800 to 853mhz covers that.
