In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 270 HIS iCooler 2GB Edition are significantly better than the AMD Radeon HD 6870 IceQ X Edition.

The R9 270 has a 25 MHz higher core clock speed and 24 more Texture Mapping Units than the HD 6870. This results in the R9 270 providing 23.6 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 R9 270 has a 25 MHz higher core clock speed than the HD 6870 and the same number of Render Output Units. This results in the R9 270 providing 0.8 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 R9 270 was released over a year more recently than the HD 6870, and so the R9 270 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 R9 270 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 R9 270 also has superior memory performance overall.

The R9 270 has 44.8 GB/sec greater memory bandwidth than the HD 6870, which means that the memory performance of the R9 270 is noticeably better than the HD 6870.

The Radeon R9 270 HIS iCooler 2GB Edition has 1280 Shader Processing Units and the Radeon HD 6870 IceQ X Edition has 1120. However, the actual shader performance of the R9 270 is 1034 and the actual shader performance of the HD 6870 is 504. The R9 270 having 530 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 270 delivers a significantly smoother and more efficient experience when processing graphical data than the HD 6870.

The R9 270 transistor size technology is 12 nm (nanometers) smaller than the HD 6870. This means that the R9 270 is expected to run slightly cooler and achieve higher clock frequencies than the HD 6870.

The Radeon R9 270 HIS iCooler 2GB Edition 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 R9 270 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 R9 270 HIS iCooler 2GB Edition is a special edition of the fast-middle-class Radeon R9 270.
This edition comes with a custom cooling system which reduces the card's temperature under load significantly but does not come overclocked out of the box and thus the performance is identical to the reference Radeon R9 270.
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.
