In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7950 Double D Edition are marginally better than the Nvidia Quadro Plex 7000.

The HD 7950 has a 226 MHz higher core clock speed but 16 fewer Texture Mapping Units than the Quadro Plex 7000. The lower TMU count doesn't matter, though, as altogether the HD 7950 manages to provide 16.1 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 7950 has a 226 MHz higher core clock speed than the Quadro Plex 7000, but the Quadro Plex 7000 has 64 more Render Output Units than the HD 7950. As a result, the Quadro Plex 7000 exhibits a 29.5 GPixel/s better Pixel Fill Rate than the HD 7950. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 7950 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.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The Quadro Plex 7000 has 9216 MB more video memory than the HD 7950, 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 48 GB/sec greater memory bandwidth than the HD 7950, which means that the memory performance of the Quadro Plex 7000 is noticeably better than the HD 7950.

The Radeon HD 7950 Double D Edition has 1792 Shader Processing Units and the Quadro Plex 7000 has 1024. However, the actual shader performance of the HD 7950 is 1219 and the actual shader performance of the Quadro Plex 7000 is 1176. The HD 7950 having 43 better shader performance is not particularly notable, as altogether the Quadro Plex 7000 performs better when taking into account other relevant data.

The HD 7950 transistor size technology is 12 nm (nanometers) smaller than the Quadro Plex 7000. This means that the HD 7950 is expected to run slightly cooler and achieve higher clock frequencies than the Quadro Plex 7000.

The Quadro Plex 7000 requires 600 Watts to run but there is no entry for the HD 7950. We would recommend a PSU with at least 500 Watts for the HD 7950 and a PSU with at least 900 Watts for the Quadro Plex 7000. The Quadro Plex 7000 has been recommended a PSU with 400 Watts more than the HD 7950. The difference is significant enough that the Quadro Plex 7000 may have an adverse affect on your yearly electricity bills in comparison to the HD 7950.

GPU Mini Review

Mini ReviewRadeon HD 7950 Double D Edition is a special edition of the Radeon HD 7950.
The new features only include a new cooling system called Double Dissipation was installed which should keep Radeon HD 7950's temperatures low under extreme loading.
The performance boost is therefore on level with the reference Radeon HD 7950 as there is no overclocking.
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.
