    ODI is very not soon(TM).
    Also Co-EMIB is not ODI.

    Those are excellent results, and they should give Renoir a hard time.

    I wonder how the 48 EU Tiger Lake is being so much better than the 64 EU Ice Lake. Maybe they Xe EUs are wider?

    Raja has posted photos of what appears to be 3 Seperate Xe -HP based GPUs.


    We have seen the one on the left hand side before but the smaller one and larger ones are new.

    Many are speculating that the larger one is a 4 Tile Arctic Sound GPU

    And this picture here that Raja posted seems to prove that:

    ATS = Arctic Sound
    4T = 4 Tiles.

    Raja also gave a vague hint on performance


    Almost 1 PetaOps, many assume this is INT8.

    256 TOPS per Arctic Sound chip.
    If that's INT8, then 128 TFLOPs FP16, 64 TFLOPs FP32?

    Naah, way too much. Unless it's using some dedicated tensor units and those are matrix operations like nvidia's hardware.

    They could very well have some tensor units in there, or some other means to run low precisions at much higher rate.
    These chips fit nicely with the old leak too
