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 7720.

The HD 6870 has a 60 MHz higher core clock speed and 16 more Texture Mapping Units than the Radeon HD 7720. This results in the HD 6870 providing 16.8 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 60 MHz higher core clock speed than the Radeon HD 7720 and the same number of Render Output Units. This results in the HD 6870 providing 1.9 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 Radeon HD 7720 was released over a year more recently than the HD 6870, and so the Radeon HD 7720 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 6870.

The Radeon HD 7720 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 memory bandwidth of the Radeon HD 7720 and the Radeon HD 6870 IceQ X Edition are the same, which means the Radeon HD 7720 and the HD 6870 have equal limitations when it comes to graphical data transfer.

The Radeon HD 7720 has 800 Shader Processing Units and the Radeon HD 6870 IceQ X Edition has 1120. However, the actual shader performance of the Radeon HD 7720 is 336 and the actual shader performance of the HD 6870 is 504. The HD 6870 having 168 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 6870 delivers a noticeably smoother and more efficient experience when processing graphical data than the Radeon HD 7720.

The Radeon HD 7720 requires 150 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 Radeon HD 7720 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 7720 is a fast-middle-class GFX that's still based on the 40nm, Terascale 2 architecture.
It's based on the Barts LE Core and offers 800 Shader Processing Units, 40 TMUs and 32 ROPs, on a 256-bit memory interface of fast GDDR5. The central unit runs at 840MHz and the memory clock operates at 1050MHz.
Therefore, it's a renamed Radeon HD 6790 and will offer exactly the same performance.
As based on the Barts LE Core, it performs better than Radeon HD 7750 (which goes against the naming) but falls behind Radeon HD 7770. It's expected to consume 150 Watt - more than Radeon HD 7750/Radeon HD 7770 and heat more, due to the higher manufacturing process. As based on the Terascale 2 architecture, it will not have nearly as much driver support as the GCN based GPUs.
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.
