In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 MSI OC 2GB Edition are massively better than the AMD FirePro V3900.

The GTX 660 has a 356 MHz higher core clock speed and 56 more Texture Mapping Units than the FirePro V3900. This results in the GTX 660 providing 64.9 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 356 MHz higher core clock speed and 16 more Render Output Units than the FirePro V3900. This results in the GTX 660 providing 18.9 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 115.4 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 GeForce GTX 660 MSI OC 2GB Edition has 960 Shader Processing Units and the FirePro V3900 has 480. However, the actual shader performance of the GTX 660 is 1029 and the actual shader performance of the FirePro V3900 is 203. The GTX 660 having 826 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 GTX 660. We would recommend a PSU with at least 350 Watts for the FirePro V3900, but we do not have a recommended PSU wattage for the GTX 660.

GPU Mini Review

Mini ReviewGeForce GTX 660 MSI OC 2GB Edition is a special edition of GeForce GTX 660.
The new features include the Propeller Blade Technology solution which generates 20% more airflow than traditional fan design, according to MSI.
In terms of overclocking, the base-clock was increased from 980MHz to 1006MHz and the boost clock can now reach 1072MHz, instead of 1033MHz. The memory clock was left untouched.
The overclocking is therefore somewhat significant and the performance boost is around 5% when compared to the standard GeForce GTX 660.
