Nvidia’s Next GPU Specs Detailed (Kepler)

Nvidia’s next generation graphics details are out. Is this the right response to AMD’s Tahiti? There are two products currently set for Q1 2012. The GK104 will represent Nvidia’s mid to high end GPU segment, while the GK100 will be Nvidia’s top of the line(GTX 580 replacement).


  • 640 to 768 CUDA cores
  • 80 to 96 TMUs (depending on what the CUDA core count ends up being)
  • 384-bit GDDR5 memory interface, 48 ROPs
  • Built on the 28 nm TSMC process
  • Products based on this will launch in the first quarter of 2012
  • GK100

  • 1024 CUDA cores
  • 128 TMUs
  • 512-bit GDDR5 memory interface, 64 ROPs

If the above specs are accurate, the highend GK100 GPU will pack twice the amount of steam processors, which could mean double the performance of a GTX580 (or equivalent GTX 590 performance). This is good news since this means we may actually see a dramatic increase in graphics performance from a single GPU.

These performance estimates aren’t to much of a stretch considering what NVidia has done in the past (GTX 9800 to GTX280 and GTX 280 to GTX 480). Nvidia intends for Kepler to provide a substantial performance increase over their current Fermi architecture.
