At the heart of the GTX 750 Ti is the GM107 GPU. The number of GM107 compute units is significantly larger than that of the GK107: 640 CUDA cores and 40 texture units instead of 384 and 32, respectively.
Not much time has passed since the release of the Radeon R290X, which could compete on par with the GEFORCE GTX TITAN, and NVIDIA released a faster graphics card, which is currently the fastest single-chip gaming solution ever released - its name is the GeForce GTX 780 Ti .
The GeForce GTX 780 is the younger brother of the single-chip flagship GeForce GTX TITAN and has similar design features, such as a cooling system and a power subsystem. The difference from the GeForce GTX TITAN is that the video card has a slightly reduced number of functional units and half the amount of video memory.
The version of GK104 used for the GeForce GTX 760 has deactivated two of the eight SMX modules. This means that the number of processors in comparison with the maximum configuration is reduced by 384 - from 1536 to 1152.
The GeForce GTX 770 is a upgraded version of the GeForce GTX 680, which received slightly increased frequency response, a more efficient cooling system from the GeForce GTX TITAN, and a more powerful power subsystem.
The GK110 became the basis for the new GeForce consumer graphics card family. At the end of February 2013, NVIDIA made a major premiere of this video accelerator. A new NVIDIA 3D gaming card was released on the already run-in GK110 GPU, which served as the basis for the Tesla K20 computing accelerator.
