In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 750 EVGA Superclocked 1GB Edition are significantly better than the Nvidia GeForce GTX 550 Ti EVGA 2GB Edition.

The GTX 750 has a 315 MHz higher core clock speed and the same number of Texture Mapping Units as the GTX 550 Ti. This results in the GTX 750 providing 10.1 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 750 has a 315 MHz higher core clock speed than the GTX 550 Ti, but the GTX 550 Ti has 8 more Render Output Units than the GTX 750. As a result, the GTX 550 Ti exhibits a 2.2 GPixel/s better Pixel Fill Rate than the GTX 750. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 750 was released over three years more recently than the GTX 550 Ti, and so the GTX 750 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GTX 550 Ti when running the latest games.

The GTX 550 Ti has 1024 MB more video memory than the GTX 750, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 550 Ti also has superior memory performance overall.

The GTX 550 Ti has 16 GB/sec greater memory bandwidth than the GTX 750, which means that the memory performance of the GTX 550 Ti is slightly better than the GTX 750.

The GeForce GTX 750 EVGA Superclocked 1GB Edition has 512 Shader Processing Units and the GeForce GTX 550 Ti EVGA 2GB Edition has 192. However, the actual shader performance of the GTX 750 is 894 and the actual shader performance of the GTX 550 Ti is 346. The GTX 750 having 548 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 750 delivers a marginally smoother and more efficient experience when processing graphical data than the GTX 550 Ti.

The GTX 750 transistor size technology is 12 nm (nanometers) smaller than the GTX 550 Ti. This means that the GTX 750 is expected to run slightly cooler and achieve higher clock frequencies than the GTX 550 Ti.

The GeForce GTX 750 EVGA Superclocked 1GB Edition requires 55 Watts to run but there is no entry for the GeForce GTX 550 Ti EVGA 2GB Edition. We would recommend a PSU with at least 300 Watts for the GTX 750 and a PSU with at least 400 Watts for the GTX 550 Ti. The GTX 550 Ti has been recommended a PSU with 100 Watts more than the GTX 750. The difference is significant enough that the GTX 550 Ti may have an adverse affect on your yearly electricity bills in comparison to the GTX 750.
