In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7950 Crossfire are noticeably better than the Nvidia GeForce GTX 680.

The GeForce GTX 680 has a 206 MHz higher core clock speed than the HD 7950, but the HD 7950 has 96 more Texture Mapping Units than the GeForce GTX 680. As a result, the HD 7950 exhibits a 50.4 GTexel/s better Texture Fill Rate than the GeForce 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 GeForce GTX 680 has a 206 MHz higher core clock speed than the HD 7950, but the HD 7950 has 32 more Render Output Units than the GeForce GTX 680. As a result, the HD 7950 exhibits a 19 GPixel/s better Pixel Fill Rate than the GeForce GTX 680. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GeForce 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 4096 MB more video memory than the GeForce 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 287.7 GB/sec greater memory bandwidth than the GeForce GTX 680, which means that the memory performance of the HD 7950 is massively better than the GeForce GTX 680.

The Radeon HD 7950 Crossfire has 3584 Shader Processing Units and the GeForce GTX 680 has 1536. However, the actual shader performance of the HD 7950 is 2437 and the actual shader performance of the GeForce GTX 680 is 1625. The HD 7950 having 812 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 GeForce GTX 680.

The Radeon HD 7950 Crossfire requires 360 Watts to run and the GeForce GTX 680 requires 195 Watts. We would recommend a PSU with at least 750 Watts for the HD 7950 and a PSU with at least 550 Watts for the GeForce GTX 680. The HD 7950 requires 165 Watts more than the GeForce 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 GeForce GTX 680.

GPU Mini Review

Mini ReviewRadeon HD 7950 Crossfire is a solution of two 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 up to 42% better than a single Radeon HD 7950 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 360 Watt though the average power consumption should be slightly lower.
Even the most demanding games will run at the highest settings.
GeForce GTX 680 is a high-end Graphics Card based on the 28nm, Kepler architecture.
The Kepler architecture allows more SPUs but the Fermi SPUs (used on the 400 & 500 Series) are clocked twice as fast as the Kepler architecture. Therefore, don't let the large amount of Pipelines fool you, as the 1536 Pipelines are equivalent to 768 Pipelines, of the Fermi architecture.
GeForce GTX 680 features a 1006Mhz core-clock that can automatically set itself to 1058Mhz using a technology similar to the one used on Intel GPUs. Another huge surprise is the TDP that went from 244 Watts, to just 195 Watts, as two SPUs of the Kepler architecture consume 10% less power. However, the amount was doubled and so the power save is not as high as it could have been.
GeForce GTX 680 was the fastest single GPU of the world until Radeon HD 7970 GHz Edition was released.
All games will run on the maximum settings smoothly.
