In terms of overall gaming performance, the graphical capabilities of the AMD FirePro V3900 are noticeably better than the AMD Radeon HD 3850 AGP.

The HD 3850 has a 18 MHz higher core clock speed than the FirePro V3900, but the FirePro V3900 has 8 more Texture Mapping Units than the HD 3850. As a result, the FirePro V3900 exhibits a 4.9 GTexel/s better Texture Fill Rate than the HD 3850. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 3850 has a 18 MHz higher core clock speed and 8 more Render Output Units than the FirePro V3900. This results in the HD 3850 providing 5.5 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 FirePro V3900 was released over three years more recently than the HD 3850, and so the FirePro V3900 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 3850 when running the latest games.

The FirePro V3900 has 512 MB more video memory than the HD 3850, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The HD 3850 has 24.3 GB/sec greater memory bandwidth than the FirePro V3900, which means that the memory performance of the HD 3850 is slightly better than the FirePro V3900.

The FirePro V3900 has 480 Shader Processing Units and the Radeon HD 3850 AGP has 320. However, the actual shader performance of the FirePro V3900 is 203 and the actual shader performance of the HD 3850 is 214. The HD 3850 having 11 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 3850 delivers a marginally 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 3850. This means that the FirePro V3900 is expected to run slightly cooler and achieve higher clock frequencies than the HD 3850.

The FirePro V3900 requires 75 Watts to run and the Radeon HD 3850 AGP requires 75 Watts. We would recommend a PSU with at least 350 Watts for the FirePro V3900 and a PSU with at least 450 Watts for the HD 3850. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

GPU Mini Review

Mini ReviewAMD FirePro� V3900 professional graphics enables an exceptional user experience by delivering features and reliability designed to help boost the productivity of professionals working with low to moderate-complexity designsRadeon HD 3850 AGP is a variant of the high-end Radeon HD 3850 based on the 55nm, second unified shader architecture, R600. Check its page to know more about its Core.
Compared to Radeon HD 3850, it features twice as much video memory and an AGP 8X Bus Interface. Benchmarks indicate the double sized frame buffer benefits this GPU largely and so its performance is up to 8% better than the reference Radeon HD 3850.
Today's modern games should run fluently at medium settings but with modest resolutions. DirectX 11 games aren't supported.
