In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 460 768MB are marginally better than the AMD Radeon HD 7770 Sapphire GHz OC Edition.

The HD 7770 has a 475 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 7770 manages to provide 8.2 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 7770 has a 475 MHz higher core clock speed than the GTX 460, but the GTX 460 has 16 more Render Output Units than the HD 7770. As a result, the GTX 460 exhibits a 3.2 GPixel/s better Pixel Fill Rate than the HD 7770. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 7770 was released over a year more recently than the GTX 460, and so the HD 7770 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 460.

The HD 7770 has 256 MB more video memory than the GTX 460, so is likely to be slightly better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The GTX 460 has 6.4 GB/sec greater memory bandwidth than the HD 7770, which means that the memory performance of the GTX 460 is marginally better than the HD 7770.

The Radeon HD 7770 Sapphire GHz OC Edition has 640 Shader Processing Units and the GeForce GTX 460 768MB has 336. However, the actual shader performance of the HD 7770 is 626 and the actual shader performance of the GTX 460 is 454. The HD 7770 having 172 better shader performance is not particularly notable, as altogether the GTX 460 performs better when taking into account other relevant data.

The HD 7770 transistor size technology is 12 nm (nanometers) smaller than the GTX 460. This means that the HD 7770 is expected to run slightly cooler and achieve higher clock frequencies than the GTX 460. While they exhibit similar graphical performance, the HD 7770 should consume less power than the GTX 460.

The Radeon HD 7770 Sapphire GHz OC Edition requires 80 Watts to run and the GeForce GTX 460 768MB requires 150 Watts. We would recommend a PSU with at least 450 Watts for the HD 7770 and a PSU with at least 450 Watts for the GTX 460. The GTX 460 requires 70 Watts more than the HD 7770 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 HD 7770.

GPU Mini Review

Mini ReviewRadeon HD 7770 Sapphire GHz OC Edition is a special edition of the fast-middle-class Radeon HD 7770. See the standard version for more information about it.
The differences include increased memory and core clocks, from 1125MHz to 1250MHz and from 1000MHz to 1150MHz, respectively. A new quiet and efficient cooling system is also available.
Benchmarks indicate a 9,5% performance boost when compared to the standard Radeon HD 7770.
Benchmarks indicate that the most demanding games (e.g. Metro 2033) will run at the highest settings but not at extreme resolutions (due to the limited memory size).
GeForce GTX 460 768MB is a high-end GPU based on the 40nm Fermi architecture.
It's based on the Fermi GF104 Core and offers 336 Shader Processing Units, 56 TMUs and 32 ROPs, on 192-bit memory interface of fast GDDR5. The central unit runs at 675MHz and the memory clock operates at 900MHz.
Compared to the reference GeForce GTX 460, it offers less memory bandwidth and a smaller frame buffer. Benchmarks indicate that its performance might be up to 8% worse than the standard version.
Most modern demanding games will run at the highest settings using a 1080p resolution. However, some will require reduced settings to be played optimally.
