In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7950 IceQ 3GB Edition are marginally better than the AMD Radeon HD 7870 PCS+ Vortex II Edition.

The HD 7870 has a 350 MHz higher core clock speed but 32 fewer Texture Mapping Units than the HD 7950. The lower TMU count doesn't matter, though, as altogether the HD 7870 manages to provide 2.4 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 HD 7870 has a 350 MHz higher core clock speed than the HD 7950 and the same number of Render Output Units. This results in the HD 7870 providing 11.2 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 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 1024 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 80 GB/sec greater memory bandwidth than the HD 7870, which means that the memory performance of the HD 7950 is much better than the HD 7870.

The Radeon HD 7950 IceQ 3GB Edition has 1792 Shader Processing Units and the Radeon HD 7870 PCS+ Vortex II Edition has 1280. However, the actual shader performance of the HD 7950 is 1219 and the actual shader performance of the HD 7870 is 1251. The HD 7870 having 32 better shader performance is not particularly notable, as altogether the HD 7950 performs better when taking into account other relevant data.

We would recommend a PSU with at least 500 Watts for the HD 7950 and a PSU with at least 500 Watts for the HD 7870. The two GPUs have been recommended a PSU with the same amount of wattage. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

GPU Mini Review

Mini ReviewRadeon HD 7950 IceQ 3GB Edition is a special edition of the Radeon HD 7950. See the standard's version page to know more about it.
The only new feature is a new cooling system called IceQ was installed which should keep Radeon HD 7950's temperatures low under extreme loading and produce less noise.
Therefore, its gaming performance is on level with the reference AMD Radeon HD 7950. Gamers will want to get the Turbo version for superior gaming performance.
Radeon HD 7870 PCS+ Vortex II Edition is a special edition of Radeon HD 7870.
This is one of today's most powerful editions of the reference as it features increases in both the core and memory clocks that went from 1000MHz to 1150MHz and from 1200MHz to 1250MHz.
Benchmarks indicate the performance boost is quite extreme and around 8% when compared to the reference Radeon HD 7870.
