Third GK104-based Single GPU Graphics Card SKU Detailed
 

After GeForce GTX 680, which has all components of the 28 nm GK104 enabled, a dual-GPU GeForce GTX 690, which features two of these chips, and the GeForce GTX 670, NVIDIA is readying its third single-GPU GK104-based SKU. We know from older reports that this SKU could be named GeForce GTX 660 (Ti). A fresh report suggests that it will be carved out by disabling an entire graphics processing cluster (GPC) on the GK104 silicon, resulting in a CUDA core count of 1152; reducing the memory bus width of 192-bit GDDR5; and most likely reducing the ROP count to 24. This SKU could be used to capture a price point of around US $249, targeting AMD's Radeon HD 7800 series.
