In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 470 Golden Sample Edition are massively better than the AMD Radeon HD 6670 v2.

The HD 6670 has a 150 MHz higher core clock speed than the GTX 470, but the GTX 470 has 32 more Texture Mapping Units than the HD 6670. As a result, the GTX 470 exhibits a 17.2 GTexel/s better Texture Fill Rate than the HD 6670. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 6670 has a 150 MHz higher core clock speed than the GTX 470, but the GTX 470 has 32 more Render Output Units than the HD 6670. As a result, the GTX 470 exhibits a 19.6 GPixel/s better Pixel Fill Rate than the HD 6670. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 6670 was released less than a year after the GTX 470, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The HD 6670 has 768 MB more video memory than the GTX 470, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GTX 470 has superior memory performance.

The GTX 470 has 110.4 GB/sec greater memory bandwidth than the HD 6670, which means that the memory performance of the GTX 470 is massively better than the HD 6670.

The Radeon HD 6670 v2 has 480 Shader Processing Units and the GeForce GTX 470 Golden Sample Edition has 448. However, the actual shader performance of the HD 6670 is 192 and the actual shader performance of the GTX 470 is 582. The GTX 470 having 390 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 470 delivers a massively smoother and more efficient experience when processing graphical data than the HD 6670.

The Radeon HD 6670 v2 requires 66 Watts to run and the GeForce GTX 470 Golden Sample Edition requires 215 Watts. We would recommend a PSU with at least 400 Watts for the HD 6670 and a PSU with at least 550 Watts for the GTX 470. The GTX 470 requires 149 Watts more than the HD 6670 to run. The difference is significant enough that the GTX 470 may have an adverse affect on your yearly electricity bills in comparison to the HD 6670.
