In terms of overall gaming performance, the graphical capabilities of the Nvidia Quadro Plex 7000 are massively better than the Nvidia GeForce GT 640 Gigabyte OC 2GB Edition.

The GT 640 has a 476 MHz higher core clock speed than the Quadro Plex 7000, but the Quadro Plex 7000 has 96 more Texture Mapping Units than the GT 640. As a result, the Quadro Plex 7000 exhibits a 39.9 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 476 MHz higher core clock speed than the Quadro Plex 7000, but the Quadro Plex 7000 has 80 more Render Output Units than the GT 640. As a result, the Quadro Plex 7000 exhibits a 38.3 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 less than a year after the Quadro Plex 7000, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The Quadro Plex 7000 has 10240 MB more video memory than the GT 640, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the Quadro Plex 7000 also has superior memory performance overall.

The Quadro Plex 7000 has 259.2 GB/sec greater memory bandwidth than the GT 640, which means that the memory performance of the Quadro Plex 7000 is massively better than the GT 640.

The GeForce GT 640 Gigabyte OC 2GB Edition has 384 Shader Processing Units and the Quadro Plex 7000 has 1024. However, the actual shader performance of the GT 640 is 403 and the actual shader performance of the Quadro Plex 7000 is 1176. The Quadro Plex 7000 having 773 better shader performance and an altogether better performance when taking into account other relevant data means that the Quadro Plex 7000 delivers a massively smoother and more efficient experience when processing graphical data than the GT 640.

The GT 640 transistor size technology is 12 nm (nanometers) smaller than the Quadro Plex 7000. This means that the GT 640 is expected to run slightly cooler and achieve higher clock frequencies than the Quadro Plex 7000.

The GeForce GT 640 Gigabyte OC 2GB Edition requires 65 Watts to run and the Quadro Plex 7000 requires 600 Watts. We would recommend a PSU with at least 350 Watts for the GT 640 and a PSU with at least 900 Watts for the Quadro Plex 7000. The Quadro Plex 7000 requires 535 Watts more than the GT 640 to run. The difference is significant enough that the Quadro Plex 7000 may have an adverse affect on your yearly electricity bills in comparison to the GT 640.

Performance
Benchmarks indicate a 8% performance over the reference GeForce GT 640.
Quadro Plex 7000 is an enthusiast professional card based on the 40nm, Fermi architecture.

It's based on 2 Fermi GF100 GPUs and thus offers 1024 Shader Processing Units, 128 TMUs and 96 ROPs, on a 768-bit memory interface of fast GDDR5. The central unit runs at 574MHz and the memory clock operates at up to 750MHz. It has a L2 Cache of 1536KB and a rated board TDP of 600 Watts.

Despite exhibiting similarities to GeForce GTX 590, due to being under-clocked and because Quadro Plex 7000's drivers are only certified for professional applications only, its gaming performance is up to 10% slower than GeForce GTX 590.
