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 7870 Crossfire.

The HD 7870 has a 200 MHz higher core clock speed than the HD 7950, but the HD 7950 has 176 more Texture Mapping Units than the HD 7870. As a result, the HD 7950 exhibits a 108.8 GTexel/s better Texture Fill Rate than the HD 7870. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 7870 has a 200 MHz higher core clock speed than the HD 7950, but the HD 7950 has 32 more Render Output Units than the HD 7870. As a result, the HD 7950 exhibits a 12.8 GPixel/s better Pixel Fill Rate than the HD 7870. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 7870 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 5120 MB more video memory than the HD 7870, 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 412.8 GB/sec greater memory bandwidth than the HD 7870, which means that the memory performance of the HD 7950 is massively better than the HD 7870.

The Radeon HD 7950 3-way Crossfire has 5376 Shader Processing Units and the Radeon HD 7870 Crossfire has 2560. However, the actual shader performance of the HD 7950 is 3656 and the actual shader performance of the HD 7870 is 2176. The HD 7950 having 1480 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 7870.

The Radeon HD 7950 3-way Crossfire requires 540 Watts to run and the Radeon HD 7870 Crossfire requires 350 Watts. We would recommend a PSU with at least 600 Watts for the HD 7870, but we do not have a recommended PSU wattage for the HD 7950. The HD 7950 requires 190 Watts more than the HD 7870 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 7870.

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.

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 44% better than a single Radeon HD 7870 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 7870. Expect this combination to draw up to 350 Watt though the average power consumption should be slightly lower.
