  • Birdie :

    Most GPU need 16wide/32wide, X1 GPU just need 4 wide ..
    me:
    on Norm GCN,4 inst/CU feed 4blck of 16wide
    on Xbox,evolution of old SPU,1nst/SPU 4wide

    implication need more inst(op)/cycle feed
    it is fit with remember my old theory of SPU 4 wide
    slide (later)
    below is GCN norm 16 wide x 4 inst
    and this is Researh paper of Nvidia + other Nvidia data

      Interesting
      Kryptos
      PS5 supposed to be ariel
      Lockhart Arden

      on Lockhart bus to BusX
      not on ariel
      PS5 will be more traditional beefed up APU

      thats why rumor X2 is to dedicatd GPU
      they forget there is BusX on Arden (supposed to be Fabric)

        • BOOM, the patent for separate die for HBM but with Logica operation, small HBM like 1GB can be L4

          ...

          Xbox GPU architect Patent !!!
          remember the leaker at Reddit of arcturus and L4
          stated the L4 die is separate from mainSOC
          birdie stated that the L4 not just standard L4, it can do operation, evolution of X1 and X360 edram which can do operation too

              • Finally new AMD patent tht answr some ?
                -Reduce CPU/Host in GPU scheduling
                -Modified GPU act as gpu coprocessor, can do scalar&vector,main fucntion act as schduler,
                this blck could also part of Next Command Processor
                start to undrstand why the X1 CP tiedly to L2 (like GPU)














                Comment


                • as in GCN-CU scheduler can't do scalar/vector,yet it is on X1 Family, unless it is GPU coprocessor, thats why the inconsistency,it is about 2 big block,

                  1.X1
                  2.GCN CU
                  3.Copro CU,notice 2 pipe,schedule Gfx & Compute?
