NVIDIA GK104 specifications revealed?

Posted on Sunday, February 12 2012 @ 21:43 CET by Thomas De Maesschalck

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)

Memory

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

Clocks/Other

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.
