In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 560 Ti Twin Frozr II 2GB are noticeably better than the Nvidia GeForce GTX 650 Ti Gainward 1GB Edition.

The GTX 650 Ti has a 106 MHz higher core clock speed and the same number of Texture Mapping Units as the GTX 560 Ti. This results in the GTX 650 Ti providing 6.8 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 650 Ti has a 106 MHz higher core clock speed than the GTX 560 Ti, but the GTX 560 Ti has 16 more Render Output Units than the GTX 650 Ti. As a result, the GTX 560 Ti exhibits a 11.5 GPixel/s better Pixel Fill Rate than the GTX 650 Ti. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 650 Ti was released less than a year after the GTX 560 Ti, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GTX 560 Ti has 1024 MB more video memory than the GTX 650 Ti, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 560 Ti also has superior memory performance overall.

The GTX 560 Ti has 41.9 GB/sec greater memory bandwidth than the GTX 650 Ti, which means that the memory performance of the GTX 560 Ti is noticeably better than the GTX 650 Ti.

The GeForce GTX 650 Ti Gainward 1GB Edition has 768 Shader Processing Units and the GeForce GTX 560 Ti Twin Frozr II 2GB has 384. However, the actual shader performance of the GTX 650 Ti is 713 and the actual shader performance of the GTX 560 Ti is 631. The GTX 650 Ti having 82 better shader performance is not particularly notable, as altogether the GTX 560 Ti performs better when taking into account other relevant data.

The GTX 650 Ti transistor size technology is 12 nm (nanometers) smaller than the GTX 560 Ti. This means that the GTX 650 Ti is expected to run slightly cooler and achieve higher clock frequencies than the GTX 560 Ti.
