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

The Radeon 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 Radeon 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 Radeon 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 Radeon HD 7950. As a result, the Quadro Plex 7000 exhibits a 29.5 GPixel/s better Pixel Fill Rate than the Radeon HD 7950. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Radeon 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 Radeon 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 Radeon HD 7950, which means that the memory performance of the Quadro Plex 7000 is noticeably better than the Radeon HD 7950.

The Quadro Plex 7000 has 1024 Shader Processing Units and the Radeon HD 7950 has 1792. However, the actual shader performance of the Quadro Plex 7000 is 1176 and the actual shader performance of the Radeon HD 7950 is 1219. The Radeon 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 Radeon HD 7950 transistor size technology is 12 nm (nanometers) smaller than the Quadro Plex 7000. This means that the Radeon 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 and the Radeon HD 7950 requires 200 Watts. We would recommend a PSU with at least 900 Watts for the Quadro Plex 7000 and a PSU with at least 500 Watts for the Radeon HD 7950. The Quadro Plex 7000 requires 400 Watts more than the Radeon HD 7950 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 Radeon HD 7950.

GPU Mini Review

Mini ReviewQuadro 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.
Radeon HD 7950 is a High-End Graphics Card based on the Graphics Core Next (GCN) Architecture.

The GCN Architecture succeeds the 40nm Terascale Architecture. In addition to being produced with a 28nm Technology, the GCN Architecture adds other Technologies that allow for energy efficiency. For example, ZeroCore Power, a long idle power saving technology, allows the Graphics Cards to shut down by itself when the Monitor is turned off.
GCN also adds Improved Anisotropic Filtering, DirectX 11 Tessellation and the Partially Resident Textures (PRT) Technology, which enables future games to utilize ultra-high resolution textures with the same performance as today's small and often repetitive textures.

It equips a GPU Codenamed Tahiti PRO which has 28 Compute Units activated and thus offers 1792 Shader Processing Units, 112 TMUs and 32 ROPs. The Central Unit is clocked at 800MHz.

The GPU accesses a 3GB frame buffer of fast GDDR5, through a 384-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The Memory Clock Operates at 1250MHz.

Power Consumption
With a rated board TDP of 200W, it requires at least a 500W PSU with two available 6-pin connectors.

Radeon HD 7950 used to compete with GeForce GTX 670 but its performance was even behind the lower positioned GeForce GTX 660 Ti and was later replaced by a faster Radeon HD 7950 Boost Edition.

System Suggestions
Radeon HD 7950 is best suited for resolutions up to and including 1920x1080. We recommend a Strong Processor (Intel Core i5 Quad Core/AMD FX Six Core) and 8GB of RAM for Optimal Performance.
