Details on Nvidia Kepler GK104-based GTX 670 Ti Surface

The next two SKUs based on the GK104 Kepler look to be set to release in May under the names GTX 670 and GTX 670 Ti. According to German publication 3DCenter.org, these GK104s will take the same route of the GF100: GK104 on the new cards will have one fewer Streaming Multiprocessors (SMX). These are basically GTX 680s that didn't make the cut during manufacturing with one of the SMX units disabled. The SMX units holds 192 CUDA cores, so with seven out of eight SMX units enabled, you end up with a 1344 CUDA core count. This allows Nvidia to salvage the graphics card and provide end-users with a card a tier or two down the performance charts.

Rumored Specifications for the GeForce GTX 670 Ti:

  • 4 Graphics Processing Clusters (GPC)
  • 7 SMX Units (192 CUDA cores per units)
  • 1344 CUDA Cores
  • 112 Texture Units (TU)
  • 32 Raster Units (ROP)
  • 256-bit Memory Controller
  • 2 GB GDDR5 Memory
  • Estimated base core clock of 900 MHz (boost clock not known)
  • Estimated 1250 MHz (5.00 GHz GDDR5 effective) memory clock, with around 160 GB/s memory bandwidth
  • Estimated price $349-399 dollars

The GTX 670 Ti is expected to see a 20 percent drop in performance when compared to the GTX 680. With its estimated performance and price point, the GTX 670 Ti is set to do battle against AMD's Radeon HD 7950 and previous generation GTX 580.

    It's only an estimation, in reality, it's most likely going to be more than the estimated price.

    I don't get it why news sites keep posting stuff that's clearly labeled as forum speculation.
