In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 750 Ti MSI Low Profile 2GB Edition are noticeably better than the Nvidia GeForce GTX 650 Ti Gainward 1GB Edition.

The GTX 750 Ti has a 92 MHz higher core clock speed than the GTX 650 Ti, but the GTX 650 Ti has 24 more Texture Mapping Units than the GTX 750 Ti. As a result, the GTX 650 Ti exhibits a 18.6 GTexel/s better Texture Fill Rate than the GTX 750 Ti. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 750 Ti has a 92 MHz higher core clock speed than the GTX 650 Ti and the same number of Render Output Units. This results in the GTX 750 Ti providing 1.5 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 750 Ti was released over a year more recently than the GTX 650 Ti, and so the GTX 750 Ti is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 650 Ti.

The GTX 750 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 750 Ti also has superior memory performance overall.

The memory bandwidth of the GeForce GTX 750 Ti MSI Low Profile 2GB Edition and the GeForce GTX 650 Ti Gainward 1GB Edition are the same, which means the GTX 750 Ti and the GTX 650 Ti have equal limitations when it comes to graphical data transfer.

The GeForce GTX 750 Ti MSI Low Profile 2GB Edition has 640 Shader Processing Units and the GeForce GTX 650 Ti Gainward 1GB Edition has 768. However, the actual shader performance of the GTX 750 Ti is 937 and the actual shader performance of the GTX 650 Ti is 713. The GTX 750 Ti having 224 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 750 Ti delivers a marginally smoother and more efficient experience when processing graphical data than the GTX 650 Ti.

The GeForce GTX 750 Ti MSI Low Profile 2GB Edition requires 60 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 750 Ti.
