In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 Inno3D Edition are significantly better than the AMD Radeon HD 5850 XFX Black 1GB Edition.

The GTX 660 has a 215 MHz higher core clock speed and 8 more Texture Mapping Units than the HD 5850. This results in the GTX 660 providing 23.3 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 GTX 660 has a 215 MHz higher core clock speed than the HD 5850, but the HD 5850 has 8 more Render Output Units than the GTX 660. As a result, the HD 5850 exhibits a 1 GPixel/s better Pixel Fill Rate than the GTX 660. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 660 was released over a year more recently than the HD 5850, and so the GTX 660 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 5850.

The GTX 660 has 1024 MB more video memory than the HD 5850, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 660 also has superior memory performance overall.

The GTX 660 has 0.2 GB/sec greater memory bandwidth than the HD 5850, which means that the memory performance of the GTX 660 is marginally better than the HD 5850.

The Radeon HD 5850 XFX Black 1GB Edition has 1440 Shader Processing Units and the GeForce GTX 660 Inno3D Edition has 960. However, the actual shader performance of the HD 5850 is 551 and the actual shader performance of the GTX 660 is 992. The GTX 660 having 441 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 660 delivers a noticeably smoother and more efficient experience when processing graphical data than the HD 5850.

The GTX 660 transistor size technology is 12 nm (nanometers) smaller than the HD 5850. This means that the GTX 660 is expected to run slightly cooler and achieve higher clock frequencies than the HD 5850.

The Radeon HD 5850 XFX Black 1GB Edition requires 151 Watts to run and the GeForce GTX 660 Inno3D Edition requires 140 Watts. We would recommend a PSU with at least 500 Watts for the HD 5850 and a PSU with at least 500 Watts for the GTX 660. The HD 5850 requires 11 Watts more than the GTX 660 to run. The difference is not significant enough for the HD 5850 to have a noticeably larger impact on your yearly electricity bills than the GTX 660.

GPU Mini Review

Mini ReviewOverview
Radeon HD 5850 XFX Black 1GB Edition is a special edition of AMD's High-End Radeon HD 5850 1GB, created by XFX.

Overclock Out of The Box
The Central Unit now runs at 765MHz, instead of 725MHz while the Memory Clock is now of 1125MHz.

Cooling Solution
The Cooling System has been replaced by XFX's custom-designed Thermal Design, meaning the Graphics Card runs cooler under load.

Performance
Benchmarks indicate a 6% performance over the reference Radeon HD 5850 1GB.
GeForce GTX 660 Inno3D Edition is a special edition of GeForce GTX 660.
It's a rename with no new features - not even a custom cooling system and so the so the performance is exactly like the standard GeForce GTX 660.
