In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7750 Crossfire are very slightly better than the AMD Radeon HD 6870 IceQ X Edition.

The HD 6870 has a 100 MHz higher core clock speed than the HD 7750, but the HD 7750 has 8 more Texture Mapping Units than the HD 6870. As a result, the HD 7750 exhibits a 0.8 GTexel/s better Texture Fill Rate than the HD 6870. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 6870 has a 100 MHz higher core clock speed than the HD 7750 and the same number of Render Output Units. This results in the HD 6870 providing 3.2 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 7750 was released less than a year after the HD 6870, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The HD 7750 has 1024 MB more video memory than the HD 6870, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 7750 also has superior memory performance overall.

The HD 7750 has 9.6 GB/sec greater memory bandwidth than the HD 6870, which means that the memory performance of the HD 7750 is marginally better than the HD 6870.

The Radeon HD 7750 Crossfire has 1024 Shader Processing Units and the Radeon HD 6870 IceQ X Edition has 1120. However, the actual shader performance of the HD 7750 is 696 and the actual shader performance of the HD 6870 is 504. The HD 7750 having 192 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7750 delivers a marginally smoother and more efficient experience when processing graphical data than the HD 6870.

The HD 7750 transistor size technology is 12 nm (nanometers) smaller than the HD 6870. This means that the HD 7750 is expected to run slightly cooler and achieve higher clock frequencies than the HD 6870.

The Radeon HD 7750 Crossfire requires 110 Watts to run but there is no entry for the Radeon HD 6870 IceQ X Edition. We would recommend a PSU with at least 500 Watts for the HD 7750 and a PSU with at least 500 Watts for the HD 6870. 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 7750 Crossfire is a solution of two Radeon HD 7750 put together using AMD'S Crossfire technology.
Check the page of Radeon HD 7750 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 up around 60% better a single Radeon HD 7750 performing by itself but at times (depending whether or not the 3D game supports crossfire or in the graphics driver) it performed worse than a single Radeon HD 7750. Expect this combination to draw up to 110 Watt though the average power consumption should be slightly lower.
Most demanding games will run at the highest settings.
Radeon HD 6870 IceQ X Edition is a special edition of the high-end Radeon HD 6870. See its page for more information about it.
Compared to the Radeon HD 6870, this Special Edition has exactly the same specifications and the only new feature is an improved cooling system which doesn't affect performance directly.
Therefore, the performance is EXACTLY like the standard Radeon HD 6870 and enough to run today's demanding games at maximum settings while Very Demanding games like Metro 2033 or Max Payne 3, will probably require reduced settings to run smoothly.
