In terms of overall gaming performance, the graphical capabilities of the GTX 650 Ti and the GTX 650 Ti are equal.

The GTX 650 Ti and the GTX 650 Ti have both the same core clock speed and the same Texture Fill Rate. 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 and the GTX 650 Ti have both the same core clock speed and the same Pixel Fill Rate. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

Both the GeForce GTX 650 Ti Gainward 2GB Edition and the GeForce GTX 650 Ti Gainward 1GB Edition were released at the same time, so are likely to be quite similar.

The GTX 650 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 650 Ti also has superior memory performance overall.

The memory bandwidth of the GeForce GTX 650 Ti Gainward 2GB Edition and the GeForce GTX 650 Ti Gainward 1GB Edition are the same, which means the GTX 650 Ti and the GTX 650 Ti have equal limitations when it comes to graphical data transfer.

Both the GeForce GTX 650 Ti Gainward 2GB Edition and the GeForce GTX 650 Ti Gainward 1GB Edition have 768 Shader Processing Units. Having the same number of SPUs and using the same architecture means that the performance they offer can be compared by looking at the memory bandwidth, Texture and Pixel Rates. In this case, the two GPUs have extremely similar stats, so any gaming performance difference would most likely be negligible.

The GeForce GTX 650 Ti Gainward 2GB Edition requires 110 Watts to run but there is no entry for the GeForce GTX 650 Ti Gainward 1GB Edition. We would recommend a PSU with at least 400 Watts for the GTX 650 Ti.
