In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7950 3-way Crossfire are significantly better than the AMD Radeon HD 7970 GHz MSI Lightning BE 3GB Edition.

The HD 7970 has a 270 MHz higher core clock speed than the HD 7950, but the HD 7950 has 208 more Texture Mapping Units than the HD 7970. As a result, the HD 7950 exhibits a 131.8 GTexel/s better Texture Fill Rate than the HD 7970. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 7970 has a 270 MHz higher core clock speed than the HD 7950, but the HD 7950 has 64 more Render Output Units than the HD 7970. As a result, the HD 7950 exhibits a 42.6 GPixel/s better Pixel Fill Rate than the HD 7970. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 7970 was released over a year more recently than the HD 7950, and so the HD 7970 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 6144 MB more video memory than the HD 7970, 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 432 GB/sec greater memory bandwidth than the HD 7970, which means that the memory performance of the HD 7950 is massively better than the HD 7970.

The Radeon HD 7970 GHz MSI Lightning BE 3GB Edition has 2048 Shader Processing Units and the Radeon HD 7950 3-way Crossfire has 5376. However, the actual shader performance of the HD 7970 is 2002 and the actual shader performance of the HD 7950 is 3656. The HD 7950 having 1654 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 HD 7970.

The Radeon HD 7970 GHz MSI Lightning BE 3GB Edition requires 300 Watts to run and the Radeon HD 7950 3-way Crossfire requires 540 Watts. We would recommend a PSU with at least 550 Watts for the HD 7970. The HD 7950 requires 240 Watts more than the HD 7970 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 HD 7970.

GPU Mini Review

Mini ReviewOverview
Radeon HD 7970 GHz MSI Lightning BE 3GB Edition is a Special Edition of AMD's High-End Radeon HD 7970 GHz Edition, created by MSI.

Overclock: Central Unit
The Central Unit is now of 1070MHz, instead of 1000MHz, while the Boost Achieves 1150MHz, instead of 1050MHz.

Overclock: Memory Clock
None.

Cooling Solution
MSIís Twin Frozr V Thermal Designs are equipped with Zero Frozr technology which was first introduced by MSI back in 2008. Zero Frozr technology eliminates fan noise in low-load situations by stopping the fans when they are not needed. Compared to other graphics cards, there is no continuous hum of airflow to tell you there's a powerful graphics card in your gaming rig.

Performance
Benchmarks Indicate a 6% Performance Boost over the Reference Radeon HD 7970 GHz 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.
