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 770 EVGA 4GB Classified Edition.

The GTX 770 has a 350 MHz higher core clock speed than the HD 7950, but the HD 7950 has 208 more Texture Mapping Units than the GTX 770. As a result, the HD 7950 exhibits a 121.6 GTexel/s better Texture Fill Rate than the GTX 770. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 770 has a 350 MHz higher core clock speed than the HD 7950, but the HD 7950 has 64 more Render Output Units than the GTX 770. As a result, the HD 7950 exhibits a 40 GPixel/s better Pixel Fill Rate than the GTX 770. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 770 was released over a year more recently than the HD 7950, and so the GTX 770 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 5120 MB more video memory than the GTX 770, 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 495.6 GB/sec greater memory bandwidth than the GTX 770, which means that the memory performance of the HD 7950 is massively better than the GTX 770.

The GeForce GTX 770 EVGA 4GB Classified Edition has 1536 Shader Processing Units and the Radeon HD 7950 3-way Crossfire has 5376. However, the actual shader performance of the GTX 770 is 1846 and the actual shader performance of the HD 7950 is 3656. The HD 7950 having 1810 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 770.

The GeForce GTX 770 EVGA 4GB Classified Edition requires 250 Watts to run and the Radeon HD 7950 3-way Crossfire requires 540 Watts. We would recommend a PSU with at least 600 Watts for the GTX 770. The HD 7950 requires 290 Watts more than the GTX 770 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 770.

GPU Mini Review

Mini ReviewGeForce GTX 770 EVGA 4GB Classified Edition is a special edition of the high-end GeForce GTX 770.
This edition comes with a custom dual fan cooling solution which by itself should allow a slight performance boost, as GeForce GTX 770 benefits from the GPU Boost 2.0 technology.
Also, it has been overclocked out of the box from 1046MHz to 1150MHz while its boost clock is now of 1202MHz. The memory clock was left untouched.
The frame buffer was doubled to 4GB which proves useless. There was no performance boost when gaming under normal circumstances (even at 2560x1600).
Benchmarks indicate a 7% performance boost when compared to the reference card and so this edition performs slightly better than GeForce GTX 590.
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.
