In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 4850 Gigabyte 512MB Edition are significantly better than the AMD FirePro V3900.

The FirePro V3900 has a 10 MHz higher core clock speed than the HD 4850, but the HD 4850 has 16 more Texture Mapping Units than the FirePro V3900. As a result, the HD 4850 exhibits a 10 GTexel/s better Texture Fill Rate than the FirePro V3900. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The FirePro V3900 has a 10 MHz higher core clock speed than the HD 4850, but the HD 4850 has 8 more Render Output Units than the FirePro V3900. As a result, the HD 4850 exhibits a 5 GPixel/s better Pixel Fill Rate than the FirePro V3900. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The FirePro V3900 was released less than a year after the HD 4850, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The FirePro V3900 has 512 MB more video memory than the HD 4850, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the HD 4850 has superior memory performance.

The HD 4850 has 31.4 GB/sec greater memory bandwidth than the FirePro V3900, which means that the memory performance of the HD 4850 is noticeably better than the FirePro V3900.

The Radeon HD 4850 Gigabyte 512MB Edition has 800 Shader Processing Units and the FirePro V3900 has 480. However, the actual shader performance of the HD 4850 is 358 and the actual shader performance of the FirePro V3900 is 203. The HD 4850 having 155 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 4850 delivers a noticeably smoother and more efficient experience when processing graphical data than the FirePro V3900.

The FirePro V3900 transistor size technology is 15 nm (nanometers) smaller than the HD 4850. This means that the FirePro V3900 is expected to run slightly cooler and achieve higher clock frequencies than the HD 4850.

The Radeon HD 4850 Gigabyte 512MB Edition requires 110 Watts to run and the FirePro V3900 requires 75 Watts. We would recommend a PSU with at least 450 Watts for the HD 4850 and a PSU with at least 350 Watts for the FirePro V3900. The HD 4850 requires 35 Watts more than the FirePro V3900 to run. The difference is significant enough that the HD 4850 may have a slight adverse affect on your yearly electricity bills in comparison to the FirePro V3900.
