In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 460 SLI are massively better than the AMD Radeon R7 240 Gigabyte OC 2GB Edition.

The R7 240 has a 105 MHz higher core clock speed than the GTX 460, but the GTX 460 has 92 more Texture Mapping Units than the R7 240. As a result, the GTX 460 exhibits a 60 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 105 MHz higher core clock speed than the GTX 460, but the GTX 460 has 56 more Render Output Units than the R7 240. As a result, the GTX 460 exhibits a 37 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 GTX 460, 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 GTX 460 when running the latest games.

The Radeon R7 240 Gigabyte OC 2GB Edition and the GeForce GTX 460 SLI have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GTX 460 has 201.6 GB/sec greater memory bandwidth than the R7 240, which means that the memory performance of the GTX 460 is massively better than the R7 240.

The Radeon R7 240 Gigabyte OC 2GB Edition has 320 Shader Processing Units and the GeForce GTX 460 SLI has 672. However, the actual shader performance of the R7 240 is 245 and the actual shader performance of the GTX 460 is 907. The GTX 460 having 662 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 460 delivers a massively 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 GTX 460. This means that the R7 240 is expected to run slightly cooler and achieve higher clock frequencies than the GTX 460.

The Radeon R7 240 Gigabyte OC 2GB Edition requires 30 Watts to run and the GeForce GTX 460 SLI requires 380 Watts. We would recommend a PSU with at least 400 Watts for the R7 240 and a PSU with at least 600 Watts for the GTX 460. The GTX 460 requires 350 Watts more than the R7 240 to run. The difference is significant enough that the GTX 460 may have an adverse affect on your yearly electricity bills in comparison to the R7 240.
