In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 Zotac AMP Edition are massively better than the AMD FirePro V3900.

The GTX 660 has a 396 MHz higher core clock speed and 56 more Texture Mapping Units than the FirePro V3900. This results in the GTX 660 providing 68.1 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 660 has a 396 MHz higher core clock speed and 16 more Render Output Units than the FirePro V3900. This results in the GTX 660 providing 19.9 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 660 was released less than a year after the FirePro V3900, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GTX 660 has 1024 MB more video memory than the FirePro V3900, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 660 also has superior memory performance overall.

The GTX 660 has 129.8 GB/sec greater memory bandwidth than the FirePro V3900, which means that the memory performance of the GTX 660 is massively better than the FirePro V3900.

The FirePro V3900 has 480 Shader Processing Units and the GeForce GTX 660 Zotac AMP Edition has 960. However, the actual shader performance of the FirePro V3900 is 203 and the actual shader performance of the GTX 660 is 1067. The GTX 660 having 864 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 660 delivers a massively smoother and more efficient experience when processing graphical data than the FirePro V3900.

The GTX 660 transistor size technology is 12 nm (nanometers) smaller than the FirePro V3900. This means that the GTX 660 is expected to run slightly cooler and achieve higher clock frequencies than the FirePro V3900.

The FirePro V3900 requires 75 Watts to run but there is no entry for the GeForce GTX 660 Zotac AMP Edition. We would recommend a PSU with at least 350 Watts for the FirePro V3900.
