In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7870 XT Sapphire Edition are very slightly better than the Nvidia GeForce GTX 460 SLI.

The HD 7870 XT has a 250 MHz higher core clock speed but 16 fewer Texture Mapping Units than the GTX 460. The lower TMU count doesn't matter, though, as altogether the HD 7870 XT manages to provide 13.2 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 7870 XT has a 250 MHz higher core clock speed than the GTX 460, but the GTX 460 has 32 more Render Output Units than the HD 7870 XT. As a result, the GTX 460 exhibits a 13.6 GPixel/s better Pixel Fill Rate than the HD 7870 XT. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 7870 XT was released over a year more recently than the GTX 460, and so the HD 7870 XT is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 460.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The GeForce GTX 460 SLI and the Radeon HD 7870 XT Sapphire Edition 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 38.4 GB/sec greater memory bandwidth than the HD 7870 XT, which means that the memory performance of the GTX 460 is noticeably better than the HD 7870 XT.

The GeForce GTX 460 SLI has 672 Shader Processing Units and the Radeon HD 7870 XT Sapphire Edition has 1536. However, the actual shader performance of the GTX 460 is 907 and the actual shader performance of the HD 7870 XT is 1208. The HD 7870 XT having 301 better shader performance is not particularly notable, as altogether the GTX 460 performs better when taking into account other relevant data.

The HD 7870 XT transistor size technology is 12 nm (nanometers) smaller than the GTX 460. This means that the HD 7870 XT is expected to run slightly cooler and achieve higher clock frequencies than the GTX 460.

The GeForce GTX 460 SLI requires 380 Watts to run but there is no entry for the Radeon HD 7870 XT Sapphire Edition. We would recommend a PSU with at least 600 Watts for the GTX 460 and a PSU with at least 500 Watts for the HD 7870 XT. The GTX 460 has been recommended a PSU with 100 Watts more than the HD 7870 XT. The difference is significant enough that the GTX 460 may have an adverse affect on your yearly electricity bills in comparison to the HD 7870 XT.

GPU Mini Review

Mini ReviewGeForce GTX 460 SLI is a solution of two GeForce GTX 460 put together using NVIDIA'S SLI technology.
SLI relies a lot on proper driver support and may cause micro stuttering in FPS below 30. This means this combination might even perform worse than a single GTX 460.
The optimal performance it delivers is slightly better than a single GeForce GTX 480.
Therefore, this combination is sufficient for gaming at 1080p and most demanding games can be played at the highest settings.
Radeon HD 7870 XT Sapphire Edition is a special edition of Radeon HD 7870 XT (not to be confused with Radeon HD 7870). Refer to Radeon 7870 XT's page to know more about it.
This edition features a new cooling system but has no overclocking out of the box and so it performs exactly like the reference Radeon HD 7870 XT.
