TPU found possible specifications of NVIDIA's GK104, the green team's new mid-range card that will take on the Radeon HD 7900 series. The new chip is anticipated to feature a different design, to allow for greater parallelism, and the specifications seem more in-line with AMD GPUs.
SIMD Hierarchy
  • 4 Graphics Processing Clusters (GPC)
  • 4 Streaming Multiprocessors (SM) per GPC = 16 SM
  • 96 Stream Processors (SP) per SM = 1536 CUDA cores

    TMU / Geometry Domain
  • 8 Texture Units (TMU) per SM = 128 TMUs
  • 32 Raster OPeration Units (ROPs)

  • 256-bit wide GDDR5 memory interface
  • 2048 MB (2 GB) memory amount standard

  • 950 MHz core/CUDA core (no hot-clocks)
  • 1250 MHz actual (5.00 GHz effective) memory, 160 GB/s memory bandwidth
  • 2.9 TFLOP/s single-precision floating point compute power
  • 486 GFLOP/s double-precision floating point compute power
  • Estimated die-area 340mm²

    Still not believing this chip, power wise, can take out a 580, no matter what they call it on paper.

    They'd better have a dual chip card come April, if they want to stay "high end" otherwise they'll basically admit (just like years ago) that they couldn't master a complex high end chip on 28nm and we'll be waiting 1-2 QUARTERS for the real high end deal...

    Those will be good quarters for AMD I'm sure.
