In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 980 EVGA Classified ACX 2.0 4GB Edition SLI are significantly better than the AMD Radeon HD 7950 3-way Crossfire.

The GTX 980 has a 491 MHz higher core clock speed but 80 fewer Texture Mapping Units than the HD 7950. The lower TMU count doesn't matter, though, as altogether the GTX 980 manages to provide 61.7 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 980 has a 491 MHz higher core clock speed and 32 more Render Output Units than the HD 7950. This results in the GTX 980 providing 88.4 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 GTX 980 was released over a year more recently than the HD 7950, and so the GTX 980 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 HD 7950 has 1024 MB more video memory than the GTX 980, 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 271.2 GB/sec greater memory bandwidth than the GTX 980, which means that the memory performance of the HD 7950 is massively better than the GTX 980.

The GeForce GTX 980 EVGA Classified ACX 2.0 4GB Edition SLI has 4096 Shader Processing Units and the Radeon HD 7950 3-way Crossfire has 5376. However, the actual shader performance of the GTX 980 is 7703 and the actual shader performance of the HD 7950 is 3656. The GTX 980 having 4047 better shader performance is not particularly notable, as altogether the HD 7950 performs better when taking into account other relevant data.

The Radeon HD 7950 3-way Crossfire requires 540 Watts to run but there is no entry for the GTX 980.

GPU Mini Review

Mini ReviewThe SLI setup of GeForce GTX 980 EVGA Classified ACX 2.0 4GB Edition.Radeon 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.
