In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX Titan SLI are very slightly better than the AMD Radeon HD 7950 3-way Crossfire.

The GTX Titan has a 37 MHz higher core clock speed and 112 more Texture Mapping Units than the HD 7950. This results in the GTX Titan providing 106.2 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 GTX Titan has a 37 MHz higher core clock speed than the HD 7950 and the same number of Render Output Units. This results in the GTX Titan providing 3.6 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 GTX Titan was released over a year more recently than the HD 7950, and so the GTX Titan is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 7950.

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 GTX Titan has 3072 MB more video memory than the HD 7950, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The HD 7950 has 143.2 GB/sec greater memory bandwidth than the GTX Titan, which means that the memory performance of the HD 7950 is massively better than the GTX Titan.

Both the Radeon HD 7950 3-way Crossfire and the GeForce GTX Titan SLI have 5376 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the GTX Titan is 4709 and by the HD 7950 is 4709. Knowing that the shader performance of the GTX Titan is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The Radeon HD 7950 3-way Crossfire requires 540 Watts to run and the GeForce GTX Titan SLI requires 500 Watts. The HD 7950 requires 40 Watts more than the GTX Titan to run. The difference is significant enough that the HD 7950 may have a slight adverse affect on your yearly electricity bills in comparison to the GTX Titan.

GPU Mini Review

Mini ReviewRadeon HD 7950 3-way Crossfire is a solution of three Radeon HD 7950 put together using AMD'S Crossfire technology.
Check the page of Radeon HD 7950 to know more about its chip.
Crossfire relies a lot on proper driver support and may suffer from micro-stuttering in lower frame rates (below 30). Benchmarks indicate the performance is overall, is somewhat superior to a single Radeon HD 7990 performing by itself it might be worse (depending on whether or not the 3D game supports crossfire or in the graphics driver) than a single Radeon HD 7950. Expect this combination to draw up to 540 Watt though the average power consumption should be slightly lower.
Even the most demanding games will run at the highest settings.
GeForce GTX Titan SLI is a solution of two GeForce GTX Titan put together using NVIDIA'S SLI technology.
Check the page of [GeForce GTX Titan](http://www.game-debate.com/hardware/index.php?gid=1582&graphics=GeForce%20GTX%20Titan) to know more about its chip.
As usual, SLI relies a lot on proper driver support and may suffer from micro-stuttering in lower frame rates (below 30). Expect this combination to draw up to 500 Watt though the average power consumption should be slightly lower.
Benchmarks indicate, an overall, 40-50% performance boost when compared to a single GeForce GTX Titan performing by itself. However, beware that this boost might be close to none in some games.
