In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R7 250 Sapphire 1GB Edition Crossfire are very slightly better than the AMD Radeon HD 6870 IceQ X Edition.

The R7 250 has a 100 MHz higher core clock speed than the HD 6870, but the HD 6870 has 8 more Texture Mapping Units than the R7 250. As a result, the HD 6870 exhibits a 2.4 GTexel/s better Texture Fill Rate than the R7 250. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The R7 250 has a 100 MHz higher core clock speed than the HD 6870, but the HD 6870 has 16 more Render Output Units than the R7 250. As a result, the HD 6870 exhibits a 12.8 GPixel/s better Pixel Fill Rate than the R7 250. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The R7 250 was released over a year more recently than the HD 6870, and so the R7 250 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 R7 250 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 R7 250 also has superior memory performance overall.

The R7 250 has 12.8 GB/sec greater memory bandwidth than the HD 6870, which means that the memory performance of the R7 250 is slightly better than the HD 6870.

The Radeon R7 250 Sapphire 1GB Edition Crossfire has 768 Shader Processing Units and the Radeon HD 6870 IceQ X Edition has 1120. However, the actual shader performance of the R7 250 is 685 and the actual shader performance of the HD 6870 is 504. The R7 250 having 181 better shader performance and an altogether better performance when taking into account other relevant data means that the R7 250 delivers a marginally smoother and more efficient experience when processing graphical data than the HD 6870.

The R7 250 transistor size technology is 12 nm (nanometers) smaller than the HD 6870. This means that the R7 250 is expected to run slightly cooler and achieve higher clock frequencies than the HD 6870.

The Radeon R7 250 Sapphire 1GB Edition Crossfire requires 130 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 R7 250 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.

Performance
Benchmarks Indicate no Performance Boost over the Reference Radeon R7 250 1GB in Crossfire.

System Suggestions
Radeon R7 250 Sapphire 1GB Edition Crossfire is best suited for resolutions up to and including 1920x1080. We Recommend a Performance Processor and 8GB of RAM for Optimal Performance.
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.
