In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7950 3-way Crossfire are significantly better than the Nvidia GeForce GTX 680 Galaxy 2GB SOC Edition.

The GTX 680 has a 402 MHz higher core clock speed than the HD 7950, but the HD 7950 has 208 more Texture Mapping Units than the GTX 680. As a result, the HD 7950 exhibits a 114.9 GTexel/s better Texture Fill Rate than the GTX 680. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 680 has a 402 MHz higher core clock speed than the HD 7950, but the HD 7950 has 64 more Render Output Units than the GTX 680. As a result, the HD 7950 exhibits a 38.3 GPixel/s better Pixel Fill Rate than the GTX 680. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 680 was released less than a year after the HD 7950, 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 HD 7950 has 7168 MB more video memory than the GTX 680, 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 527.7 GB/sec greater memory bandwidth than the GTX 680, which means that the memory performance of the HD 7950 is massively better than the GTX 680.

The Radeon HD 7950 3-way Crossfire has 5376 Shader Processing Units and the GeForce GTX 680 Galaxy 2GB SOC Edition has 1536. However, the actual shader performance of the HD 7950 is 3656 and the actual shader performance of the GTX 680 is 1946. The HD 7950 having 1710 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 GTX 680.

The Radeon HD 7950 3-way Crossfire requires 540 Watts to run and the GeForce GTX 680 Galaxy 2GB SOC Edition requires 195 Watts. We would recommend a PSU with at least 550 Watts for the GTX 680, but we do not have a recommended PSU wattage for the HD 7950. The HD 7950 requires 345 Watts more than the GTX 680 to run. The difference is significant enough that the HD 7950 may have an adverse affect on your yearly electricity bills in comparison to the GTX 680.

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 680 Galaxy 2GB SOC Edition is a Special Edition of the powerful GeForce GTX 680. See the standard version for more information about it.
Compared to the standard version, GeForce GTX 680 Galaxy 2GB SOC Edition features an increased core-clock that was raised from 1006MHz to 1202MHz while the "Boost Clock" can now attain 1267MHz. A triple fan cooling system is also available.
The changes are impressive but there are no benchmarks available and so this GPU's rank is predicted.
It's worth mentioning this GPU does not offer any DVI Ports.
