The GTX 650 Ti Boost is based on GK106 silicon produced on TSMC’s 28nm manufacturing process. There are 4 SMX units, 768 CUDA Cores, 64 Texture Units, and 24 ROPs. The clock speed runs at a base clock of 980MHz with a Boost clock of 1033MHz. In terms of memory, the GeForce GTX 650 Ti Boost has 1GB or 2GB of GDDR5 on a 192-bit memory bus at 6GHz providing 144GB/sec of memory bandwidth.
Total board power is 140W and requires only one 6-pin power connector. In addition, this video card will still support the same 4-display setup that the GTX 660 Ti, GTX 670, and GTX 680 support. You will find 2x DL-DVI, HDMI and DisplayPort 1.2 on board as well as PCI Express 3.0. The GPU only supports 2-way SLI, unlike its bigger siblings which are capable of a 3-way SLI experience.
