In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 640 v3 Zotac 2GB Edition are noticeably better than the Nvidia Quadro FX 4800.

The GT 640 was released over a year more recently than the Quadro FX 4800, and so the GT 640 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Quadro FX 4800.

The GT 640 has 512 MB more video memory than the Quadro FX 4800, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GT 640 also has superior memory performance overall.

The Quadro FX 4800 has 36.7 GB/sec greater memory bandwidth than the GT 640, which means that the memory performance of the Quadro FX 4800 is noticeably better than the GT 640.

The GeForce GT 640 v3 Zotac 2GB Edition has 384 Shader Processing Units and the Quadro FX 4800 has 192. However, the actual shader performance of the GT 640 is 402 and the actual shader performance of the Quadro FX 4800 is 116. The GT 640 having 286 better shader performance is not particularly notable, as altogether the Quadro FX 4800 performs better when taking into account other relevant data.

The GT 640 transistor size technology is 37 nm (nanometers) smaller than the Quadro FX 4800. This means that the GT 640 is expected to run much cooler and achieve higher clock frequencies than the Quadro FX 4800.

The GeForce GT 640 v3 Zotac 2GB Edition requires 49 Watts to run and the Quadro FX 4800 requires 150 Watts. We would recommend a PSU with at least 350 Watts for the GT 640 and a PSU with at least 750 Watts for the Quadro FX 4800. The Quadro FX 4800 requires 101 Watts more than the GT 640 to run. The difference is significant enough that the Quadro FX 4800 may have an adverse affect on your yearly electricity bills in comparison to the GT 640.
