In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7950 VTX3D 3GB Boost X-Edition are massively better than the Nvidia GeForce 8800 GTS 512MB SLI.

The HD 7950 has a 230 MHz higher core clock speed but 16 fewer Texture Mapping Units than the 8800 GTS. The lower TMU count doesn't matter, though, as altogether the HD 7950 manages to provide 15.4 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 230 MHz higher core clock speed than the 8800 GTS and the same number of Render Output Units. This results in the HD 7950 providing 7.4 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 7950 was released over three years more recently than the 8800 GTS, and so the HD 7950 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the 8800 GTS when running the latest games.

The HD 7950 has 2048 MB more video memory than the 8800 GTS, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 7950 also has superior memory performance overall.

The HD 7950 has 137.6 GB/sec greater memory bandwidth than the 8800 GTS, which means that the memory performance of the HD 7950 is massively better than the 8800 GTS.

The GeForce 8800 GTS 512MB SLI has 256 Shader Processing Units and the Radeon HD 7950 VTX3D 3GB Boost X-Edition has 1792. However, the actual shader performance of the 8800 GTS is 166 and the actual shader performance of the HD 7950 is 1417. The HD 7950 having 1251 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7950 delivers a massively smoother and more efficient experience when processing graphical data than the 8800 GTS.

The HD 7950 transistor size technology is 37 nm (nanometers) smaller than the 8800 GTS. This means that the HD 7950 is expected to run much cooler and achieve higher clock frequencies than the 8800 GTS.

The GeForce 8800 GTS 512MB SLI requires 270 Watts to run but there is no entry for the Radeon HD 7950 VTX3D 3GB Boost X-Edition. We would recommend a PSU with at least 650 Watts for the 8800 GTS and a PSU with at least 500 Watts for the HD 7950. The 8800 GTS has been recommended a PSU with 150 Watts more than the HD 7950. The difference is significant enough that the 8800 GTS may have an adverse affect on your yearly electricity bills in comparison to the HD 7950.
