In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 580 Lightning Xtreme Edition are very slightly better than the AMD Radeon HD 7870 DirectCU II 2GB Edition.

The HD 7870 has a 178 MHz higher core clock speed and 16 more Texture Mapping Units than the GTX 580. This results in the HD 7870 providing 27.6 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 has a 178 MHz higher core clock speed than the GTX 580, but the GTX 580 has 16 more Render Output Units than the HD 7870. As a result, the GTX 580 exhibits a 7.6 GPixel/s better Pixel Fill Rate than the HD 7870. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 7870 was released over a year more recently than the GTX 580, and so the HD 7870 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 580.

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 GTX 580 has 1024 MB more video memory than the HD 7870, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 580 also has superior memory performance overall.

The GTX 580 has 46.7 GB/sec greater memory bandwidth than the HD 7870, which means that the memory performance of the GTX 580 is noticeably better than the HD 7870.

The Radeon HD 7870 DirectCU II 2GB Edition has 1280 Shader Processing Units and the GeForce GTX 580 Lightning Xtreme Edition has 512. However, the actual shader performance of the HD 7870 is 1099 and the actual shader performance of the GTX 580 is 852. The HD 7870 having 247 better shader performance is not particularly notable, as altogether the GTX 580 performs better when taking into account other relevant data.

The HD 7870 transistor size technology is 12 nm (nanometers) smaller than the GTX 580. This means that the HD 7870 is expected to run slightly cooler and achieve higher clock frequencies than the GTX 580.

The GeForce GTX 580 Lightning Xtreme Edition requires 244 Watts to run but there is no entry for the HD 7870. We would recommend a PSU with at least 600 Watts for the GTX 580, but we do not have a recommended PSU wattage for the HD 7870.

GPU Mini Review

Mini ReviewRadeon HD 7870 DirectCU II 2GB Edition is a special edition of the powerful Radeon HD 7870. See the standard version for more information about it.
The new features include the DirectCU II cooling solution which is 20% more effective than the reference cooler, according to Asus and a small increase in the core-clock to 1010MHz as well as in the memory clock to 1210MHz.
Benchmarks indicate almost no performance boost when compared to the standard Radeon HD 7870 and so its performance is on level with the it as the boost is beneath 1%.
All games, including demanding one's, will run on the highest settings.
GeForce GTX 580 Lightning Xtreme Edition is a special edition of the powerful GeForce GTX 580. See the standard version for more information about it.
The differences include increased memory and core clocks, from 4008MHz to 4200MHz and from 772MHz to 832MHz, respectively. It also includes a better cooling system to reduce the heat that resulted from the huge overclocking. The amount of video memory was doubled and is quite handy, if gaming at extreme resolutions with image improving techniques.
Benchmarks indicate a performance boost of about 3% when compared to the standard GeForce GTX 580.
All games, including demanding one's, will run on the highest settings.
