In terms of overall gaming performance, the graphical capabilities of the AMD FirePro V5800 are marginally better than the Nvidia GeForce GT 640 v3 Zotac 2GB Edition.

The GT 640 has a 346 MHz higher core clock speed than the FirePro V5800, but the FirePro V5800 has 24 more Texture Mapping Units than the GT 640. As a result, the FirePro V5800 exhibits a 11.3 GTexel/s better Texture Fill Rate than the GT 640. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GT 640 has a 346 MHz higher core clock speed than the FirePro V5800, but the FirePro V5800 has 8 more Render Output Units than the GT 640. As a result, the FirePro V5800 exhibits a 2.8 GPixel/s better Pixel Fill Rate than the GT 640. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GT 640 was released over three years more recently than the FirePro V5800, and so the GT 640 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the FirePro V5800 when running the latest games.

The GT 640 has 1024 MB more video memory than the FirePro V5800, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The FirePro V5800 has 23.9 GB/sec greater memory bandwidth than the GT 640, which means that the memory performance of the FirePro V5800 is slightly better than the GT 640.

The GeForce GT 640 v3 Zotac 2GB Edition has 384 Shader Processing Units and the FirePro V5800 has 800. However, the actual shader performance of the GT 640 is 402 and the actual shader performance of the FirePro V5800 is 364. The GT 640 having 38 better shader performance is not particularly notable, as altogether the FirePro V5800 performs better when taking into account other relevant data.

The GT 640 transistor size technology is 12 nm (nanometers) smaller than the FirePro V5800. This means that the GT 640 is expected to run slightly cooler and achieve higher clock frequencies than the FirePro V5800. While they exhibit similar graphical performance, the GT 640 should consume less power than the FirePro V5800.

The GeForce GT 640 v3 Zotac 2GB Edition requires 49 Watts to run and the FirePro V5800 requires 74 Watts. We would recommend a PSU with at least 350 Watts for the GT 640 and a PSU with at least 400 Watts for the FirePro V5800. The FirePro V5800 requires 25 Watts more than the GT 640 to run. The difference is not significant enough for the FirePro V5800 to have a noticeably larger impact on your yearly electricity bills than the GT 640.

GPU Mini Review

Mini ReviewOverview
GeForce GT 640 v3 Zotac 2GB Edition is a special edition of NVIDIA's Middle-Class GeForce GT 640 v3, created by Zotac.

Overclock: Central Unit
The Central Unit runs at the same speed.

Overclock: Memory Clock
The Operating Memory Clock and the Frame Buffer remain the same.

Cooling Solution
The Cooling System has been replaced by Zotac's Silent Cooling Solution.

Without Overclocking Out of The Box, GeForce GT 640 v3 Zotac 2GB Edition is as fast as the reference GeForce GT 640 v3.
FirePro V5800 is a professional graphics card based on the 40nm Terascale 2 architecture.
It's based on the Juniper XT Core (same used on Radeon HD 6770) and therefore offers 800 Shader Processing Units, 40 TMUs and 16 ROPs on a 128-bit interface of fast GDDR5. The central unit is clocked 700MHz while the memory clock operates at 1000MHZ.
Compared to Radeon HD 6770, its central unit is underclocked and overall its gaming performance is even lower than Radeon HD 6770 because the latter benefits from certified gaming drivers which unlock the Terascale's architecture potential while FirePro W5800 is made for professional applications. Therefore, expect its performance to be between 7% and 10% worse than Radeon HD 6770.
