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 7660D + 7670 Dual.

The HD 7660D has no core clock speed set, so any comparison between Texture and Pixel Fill Rates is not currently possible.

The HD 7660D was released over a year more recently than the GTX 470, and so the HD 7660D is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 470.

The GTX 470 has 256 MB more video memory than the HD 7660D, so is likely to be slightly better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 470 also has superior memory performance overall.

The GTX 470 has 107.2 GB/sec greater memory bandwidth than the HD 7660D, which means that the memory performance of the GTX 470 is massively better than the HD 7660D.

The GeForce GTX 470 Golden Sample Edition has 448 Shader Processing Units and the Radeon HD 7660D + 7670 Dual has 760. However, the actual shader performance of the GTX 470 is 582 and the actual shader performance of the HD 7660D is 0. The GTX 470 having 582 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 7660D.

The GeForce GTX 470 Golden Sample Edition requires 215 Watts to run but there is no entry for the Radeon HD 7660D + 7670 Dual. We would recommend a PSU with at least 550 Watts for the GTX 470.
