In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 6750 v2 PowerColor 2GB Edition are noticeably better than the AMD Radeon R7 240 2GB.

The R7 240 has a 30 MHz higher core clock speed than the HD 6750, but the HD 6750 has 16 more Texture Mapping Units than the R7 240. As a result, the HD 6750 exhibits a 10.6 GTexel/s better Texture Fill Rate than the R7 240. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The R7 240 has a 30 MHz higher core clock speed than the HD 6750, but the HD 6750 has 8 more Render Output Units than the R7 240. As a result, the HD 6750 exhibits a 5.4 GPixel/s better Pixel Fill Rate than the R7 240. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The R7 240 was released over a year more recently than the HD 6750, and so the R7 240 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 6750.

The Radeon HD 6750 v2 PowerColor 2GB Edition and the Radeon R7 240 2GB have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The R7 240 has 7.5 GB/sec greater memory bandwidth than the HD 6750, which means that the memory performance of the R7 240 is marginally better than the HD 6750.

The Radeon HD 6750 v2 PowerColor 2GB Edition has 720 Shader Processing Units and the Radeon R7 240 2GB has 320. However, the actual shader performance of the HD 6750 is 252 and the actual shader performance of the R7 240 is 212. The HD 6750 having 40 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 6750 delivers a marginally smoother and more efficient experience when processing graphical data than the R7 240.

The R7 240 transistor size technology is 12 nm (nanometers) smaller than the HD 6750. This means that the R7 240 is expected to run slightly cooler and achieve higher clock frequencies than the HD 6750.

The Radeon HD 6750 v2 PowerColor 2GB Edition requires 86 Watts to run and the Radeon R7 240 2GB requires 30 Watts. We would recommend a PSU with at least 450 Watts for the HD 6750 and a PSU with at least 400 Watts for the R7 240. The HD 6750 requires 56 Watts more than the R7 240 to run. The difference is significant enough that the HD 6750 may have an adverse affect on your yearly electricity bills in comparison to the R7 240.
