In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 470 are marginally better than the AMD Radeon HD 6870 PowerColor 1GB Edition.

The HD 6870 has a 293 MHz higher core clock speed and the same number of Texture Mapping Units as the GeForce GTX 470. This results in the HD 6870 providing 16.4 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 6870 has a 293 MHz higher core clock speed but 8 fewer Render Output Units than the GeForce GTX 470. The lower ROP count doesn't matter, though, as altogether the HD 6870 manages to provide 4.5 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 HD 6870 was released over a year more recently than the GeForce GTX 470, and so the HD 6870 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce GTX 470.

The GeForce GTX 470 has 256 MB more video memory than the HD 6870, so is likely to be slightly better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The HD 6870 has 0.5 GB/sec greater memory bandwidth than the GeForce GTX 470, which means that the memory performance of the HD 6870 is marginally better than the GeForce GTX 470.

The Radeon HD 6870 PowerColor 1GB Edition has 1120 Shader Processing Units and the GeForce GTX 470 has 448. However, the actual shader performance of the HD 6870 is 504 and the actual shader performance of the GeForce GTX 470 is 544. The GeForce GTX 470 having 40 better shader performance is not particularly notable, as altogether the HD 6870 performs better when taking into account other relevant data.

The GeForce GTX 470 requires 215 Watts to run but there is no entry for the HD 6870. We would recommend a PSU with at least 500 Watts for the HD 6870 and a PSU with at least 550 Watts for the GeForce GTX 470. The GeForce GTX 470 has been recommended a PSU with 50 Watts more than the HD 6870. The difference is significant enough that the GeForce GTX 470 may have a slight adverse affect on your yearly electricity bills in comparison to the HD 6870.

GPU Mini Review

Mini ReviewRadeon HD 6870 PowerColor 1GB Edition is a special edition of the high-end Radeon HD 6870. See its page for more information about it.
It has no new features and so it can be addressed as a renamed Radeon HD 6870. Therefore its performance is exactly like the standard's.
GeForce GTX 470 is a high-end GPU based on the 40nm Fermi architecture.
It's based on the Fermi GF100 Core and offers 480 Shader Processing Units, 56 TMUs and 40 ROPs. The central unit runs at 607MHz and the memory clock operates at 837MHz.
Compared to GeForce GTX 480, it delivers considerably worse performance due to the lower SPU count and lower clocked central unit and therefore also lower Shaders speed.
Most modern demanding games will run at the highest settings using a 1080p resolution. However, some will require reduced settings to be played optimally.
