In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 680 Galaxy Edition are massively better than the AMD Radeon HD 6870 XFX Black Edition.

The GTX 680 has a 170 MHz higher core clock speed and 72 more Texture Mapping Units than the HD 6870. This results in the GTX 680 providing 89.5 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 680 has a 170 MHz higher core clock speed than the HD 6870 and the same number of Render Output Units. This results in the GTX 680 providing 5.4 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 680 was released over a year more recently than the HD 6870, and so the GTX 680 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 6870.

The GTX 680 has 3072 MB more video memory than the HD 6870, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 680 also has superior memory performance overall.

The GTX 680 has 45.1 GB/sec greater memory bandwidth than the HD 6870, which means that the memory performance of the GTX 680 is noticeably better than the HD 6870.

The Radeon HD 6870 XFX Black Edition has 1120 Shader Processing Units and the GeForce GTX 680 Galaxy Edition has 1536. However, the actual shader performance of the HD 6870 is 526 and the actual shader performance of the GTX 680 is 1806. The GTX 680 having 1280 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 680 delivers a massively smoother and more efficient experience when processing graphical data than the HD 6870.

The GTX 680 transistor size technology is 12 nm (nanometers) smaller than the HD 6870. This means that the GTX 680 is expected to run slightly cooler and achieve higher clock frequencies than the HD 6870.

The Radeon HD 6870 XFX Black Edition requires 151 Watts to run and the GeForce GTX 680 Galaxy Edition requires 195 Watts. We would recommend a PSU with at least 650 Watts for the HD 6870 and a PSU with at least 550 Watts for the GTX 680. The GTX 680 requires 44 Watts more than the HD 6870 to run. The difference is significant enough that the GTX 680 may have a slight adverse affect on your yearly electricity bills in comparison to the HD 6870.

GPU Mini Review

Mini ReviewRadeon HD 6870 XFX Black Edition is a special edition of the Radeon HD 6870, part of the Radeon HD 6000 Series released by AMD in 2010/2011. See the page of the standard version for more information about it.
Compared to the standard edition, Radeon HD 6870 XFX Black Edition features increased core and memory clocks, as well as a special fan to reduce the temperature increase that results from the over-clocking.
The performance is boost is around 3.5% when compared to the reference Radeon HD 6870.
GeForce GTX 680 Galaxy Edition is a Special Edition of the powerful GeForce GTX 680. See the standard version for more information about it.
Compared to the standard version, GeForce GTX 680 Galaxy Edition features an increased core-clock that went from 1006MHz to 1110MHz and the turbo boost from 1100MHz to 1176MHz. The amount of memory was also increased from 2GB to 4GB, proving useful if gaming at high resolutions and using many image improving techniques, though we consider this excessive.
Expect a 9% performance boost when compared to the standard card.
