Gigabyte's GeForce GTX 650 Ti lineup includes a total of three models, the GeForce GTX 650 Ti 1 GB base (GV-N65T-1GI), the GeForce GTX 650 Ti 1 GB OC (GV-N65TOC-1GI), and the premium GeForce GTX 650 Ti 2 GB OC WindForce 2X (GV-N65TOC-2GI). The two 1 GB variants use a compact PCB inspired by NVIDIA reference design, and a single 100 mm fan Triangle-Cool heatsink. The 1 GB base model sticks to NVIDIA-reference clock speeds of 925 MHz core and 5.40 GHz memory, the 1 GB OC version ups the core speed to 1033 MHz core, and the WindForce 2X OC version doubles its memory to 2 GB. Based on the 28 nm GK106 silicon, the GeForce GTX 650 Ti packs 768 CUDA cores, 64 TMUs, 16 ROPs, and a 128-bit wide memory interface. Prices remain under wraps.
