In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 6870 PowerColor 1GB Edition are significantly better than the AMD Radeon R7 250 2GB.

The R7 250 has a 100 MHz higher core clock speed than the HD 6870, but the HD 6870 has 32 more Texture Mapping Units than the R7 250. As a result, the HD 6870 exhibits a 26.4 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 24 more Render Output Units than the R7 250. As a result, the HD 6870 exhibits a 20.8 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. However, the overall memory performance is about the same.

The HD 6870 has 60.8 GB/sec greater memory bandwidth than the R7 250, which means that the memory performance of the HD 6870 is much better than the R7 250.

The Radeon R7 250 2GB has 384 Shader Processing Units and the Radeon HD 6870 PowerColor 1GB Edition has 1120. However, the actual shader performance of the R7 250 is 343 and the actual shader performance of the HD 6870 is 504. The HD 6870 having 161 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 R7 250.

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 2GB requires 65 Watts to run but there is no entry for the Radeon HD 6870 PowerColor 1GB Edition. We would recommend a PSU with at least 400 Watts for the R7 250 and a PSU with at least 500 Watts for the HD 6870. The HD 6870 has been recommended a PSU with 100 Watts more than the R7 250. The difference is significant enough that the HD 6870 may have an adverse affect on your yearly electricity bills in comparison to the R7 250.

GPU Mini Review

Mini ReviewNote: This Graphics Card has 2 variants: one with DDR3 and another with GDDR5. This is the GDDR5 Version.

Radeon R7 250 2GB offers a GCN 1.1 Core codenamed Oland PRO and thus features 384 Shader Processing Units, 24 TMUs and 8 ROPs, on a 128-bit bus width of fast GDDR5. While the central unit runs at 1000MHz and goes up to 1050MHz, in Turbo Mode, the memory clock operates at 1150MHz.
The 2GB frame buffer will not boost its performance and can be addressed as a gimmick - marketing to lure consumers into paying more for the same product.
With a rated board TDP of 65W, it requires no extra power connectors.

Its performance is overall similar to previous Radeon HD 7750 and up to 10% faster than the DDR3 v2 version. However, at lower resolutions, both cards offer similar performance.
Radeon HD 6870 PowerColor 1GB Edition is a special edition of the high-end Radeon HD 6870. See its page for more information about it.
It has no new features and so it can be addressed as a renamed Radeon HD 6870. Therefore its performance is exactly like the standard's.
