In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTS 240 are noticeably better than the AMD Radeon R7 240 2GB.

The R7 240 has a 55 MHz higher core clock speed than the GeForce GTS 240, but the GeForce GTS 240 has 36 more Texture Mapping Units than the R7 240. As a result, the GeForce GTS 240 exhibits a 23.2 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 55 MHz higher core clock speed than the GeForce GTS 240, but the GeForce GTS 240 has 8 more Render Output Units than the R7 240. As a result, the GeForce GTS 240 exhibits a 5 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 three years more recently than the GeForce GTS 240, and so the R7 240 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce GTS 240 when running the latest games.

The R7 240 has 1024 MB more video memory than the GeForce GTS 240, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GeForce GTS 240 has superior memory performance.

The GeForce GTS 240 has 41.6 GB/sec greater memory bandwidth than the R7 240, which means that the memory performance of the GeForce GTS 240 is noticeably better than the R7 240.

The Radeon R7 240 2GB has 320 Shader Processing Units and the GeForce GTS 240 has 112. However, the actual shader performance of the R7 240 is 212 and the actual shader performance of the GeForce GTS 240 is 189. The R7 240 having 23 better shader performance is not particularly notable, as altogether the GeForce GTS 240 performs better when taking into account other relevant data.

The R7 240 transistor size technology is 27 nm (nanometers) smaller than the GeForce GTS 240. This means that the R7 240 is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GTS 240.

The Radeon R7 240 2GB requires 30 Watts to run and the GeForce GTS 240 requires 120 Watts. We would recommend a PSU with at least 400 Watts for the R7 240 and a PSU with at least 450 Watts for the GeForce GTS 240. The GeForce GTS 240 requires 90 Watts more than the R7 240 to run. The difference is significant enough that the GeForce GTS 240 may have an adverse affect on your yearly electricity bills in comparison to the R7 240.
