In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 750 EVGA Superclocked 1GB Edition are significantly better than the AMD Radeon R7 250 Gigabyte OC 2GB Edition.

The GTX 750 has a 165 MHz higher core clock speed and 8 more Texture Mapping Units than the R7 250. This results in the GTX 750 providing 13.7 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 165 MHz higher core clock speed and 8 more Render Output Units than the R7 250. This results in the GTX 750 providing 11 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 was released less than a year after the R7 250, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The R7 250 has 1024 MB more video memory than the GTX 750, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GTX 750 has superior memory performance.

The GTX 750 has 6.6 GB/sec greater memory bandwidth than the R7 250, which means that the memory performance of the GTX 750 is marginally better than the R7 250.

The Radeon R7 250 Gigabyte OC 2GB Edition has 384 Shader Processing Units and the GeForce GTX 750 EVGA Superclocked 1GB Edition has 512. However, the actual shader performance of the R7 250 is 359 and the actual shader performance of the GTX 750 is 894. The GTX 750 having 535 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 750 delivers a noticeably smoother and more efficient experience when processing graphical data than the R7 250.

The Radeon R7 250 Gigabyte OC 2GB Edition requires 65 Watts to run and the GeForce GTX 750 EVGA Superclocked 1GB Edition requires 55 Watts. We would recommend a PSU with at least 400 Watts for the R7 250 and a PSU with at least 300 Watts for the GTX 750. The R7 250 requires 10 Watts more than the GTX 750 to run. The difference is not significant enough for the R7 250 to have a noticeably larger impact on your yearly electricity bills than the GTX 750.
