In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 270 HIS IceQ X² 2GB Edition are significantly better than the Nvidia GeForce GTX 750 EVGA Superclocked 1GB Edition.

The GTX 750 has a 315 MHz higher core clock speed than the R9 270, but the R9 270 has 48 more Texture Mapping Units than the GTX 750. As a result, the R9 270 exhibits a 33.1 GTexel/s better Texture Fill Rate than the GTX 750. 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 R9 270, but the R9 270 has 16 more Render Output Units than the GTX 750. As a result, the R9 270 exhibits a 9.4 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 less than a year after the R9 270, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The R9 270 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 R9 270 also has superior memory performance overall.

The R9 270 has 99 GB/sec greater memory bandwidth than the GTX 750, which means that the memory performance of the R9 270 is massively better than the GTX 750.

The Radeon R9 270 HIS IceQ X² 2GB Edition has 1280 Shader Processing Units and the GeForce GTX 750 EVGA Superclocked 1GB Edition has 512. However, the actual shader performance of the R9 270 is 1006 and the actual shader performance of the GTX 750 is 894. The R9 270 having 112 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 270 delivers a massively smoother and more efficient experience when processing graphical data than the GTX 750.

The Radeon R9 270 HIS IceQ X² 2GB Edition requires 150 Watts to run and the GeForce GTX 750 EVGA Superclocked 1GB Edition requires 55 Watts. We would recommend a PSU with at least 500 Watts for the R9 270 and a PSU with at least 300 Watts for the GTX 750. The R9 270 requires 95 Watts more than the GTX 750 to run. The difference is significant enough that the R9 270 may have an adverse affect on your yearly electricity bills in comparison to the GTX 750.
