In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 6870 IceQ X Edition are significantly better than the AMD Radeon HD 7750 Asus 1GB Edition.

The HD 6870 has a 80 MHz higher core clock speed and 24 more Texture Mapping Units than the HD 7750. This results in the HD 6870 providing 24.2 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 6870 has a 80 MHz higher core clock speed and 16 more Render Output Units than the HD 7750. This results in the HD 6870 providing 15.7 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 Radeon HD 7750 Asus 1GB Edition and the Radeon HD 6870 IceQ X Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The HD 6870 has 60.8 GB/sec greater memory bandwidth than the HD 7750, which means that the memory performance of the HD 6870 is much better than the HD 7750.

The Radeon HD 7750 Asus 1GB Edition has 512 Shader Processing Units and the Radeon HD 6870 IceQ X Edition has 1120. However, the actual shader performance of the HD 7750 is 357 and the actual shader performance of the HD 6870 is 504. The HD 6870 having 147 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 6870 delivers a massively smoother and more efficient experience when processing graphical data than the HD 7750.

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.

We would recommend a PSU with at least 500 Watts for the HD 6870, but we do not have a recommended PSU wattage for the HD 7750.

GPU Mini Review

Mini ReviewRadeon HD 7750 Asus 1GB Edition is a tweaked Radeon HD 7750 with a custom cooling system and small increases in the core and memory clocks that went from 800MHz to 820MHz and 1125MHz to 1150MHz, respectively.
The performance boost is only slightly and around 1%, according to benchmarks.
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.
