In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 460 PNY 1GB OC Edition are noticeably better than the AMD Radeon R7 250X.

The Radeon R7 250X has a 185 MHz higher core clock speed than the GTX 460, but the GTX 460 has 16 more Texture Mapping Units than the Radeon R7 250X. As a result, the GTX 460 exhibits a 4.8 GTexel/s better Texture Fill Rate than the Radeon R7 250X. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The Radeon R7 250X has a 185 MHz higher core clock speed than the GTX 460, but the GTX 460 has 16 more Render Output Units than the Radeon R7 250X. As a result, the GTX 460 exhibits a 9.3 GPixel/s better Pixel Fill Rate than the Radeon R7 250X. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Radeon R7 250X was released over three years more recently than the GTX 460, and so the Radeon R7 250X 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 250X has 1024 MB more video memory than the GTX 460, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The GTX 460 has 46.4 GB/sec greater memory bandwidth than the Radeon R7 250X, which means that the memory performance of the GTX 460 is noticeably better than the Radeon R7 250X.

The Radeon R7 250X has 640 Shader Processing Units and the GeForce GTX 460 PNY 1GB OC Edition has 336. However, the actual shader performance of the Radeon R7 250X is 517 and the actual shader performance of the GTX 460 is 514. The Radeon R7 250X having 3 better shader performance is not particularly notable, as altogether the GTX 460 performs better when taking into account other relevant data.

The Radeon R7 250X transistor size technology is 12 nm (nanometers) smaller than the GTX 460. This means that the Radeon R7 250X is expected to run slightly cooler and achieve higher clock frequencies than the GTX 460.

The Radeon R7 250X requires 80 Watts to run but there is no entry for the GeForce GTX 460 PNY 1GB OC Edition. We would recommend a PSU with at least 450 Watts for the Radeon R7 250X and a PSU with at least 450 Watts for the GTX 460. The two GPUs have been recommended a PSU with the same amount of wattage. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.
