In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 280X XFX Double D 3GB Edition are significantly better than the AMD Radeon HD 7850 XFX Ultra OC Edition.

The HD 7850 has a 125 MHz higher core clock speed than the R9 280X, but the R9 280X has 64 more Texture Mapping Units than the HD 7850. As a result, the R9 280X exhibits a 46.4 GTexel/s better Texture Fill Rate than the HD 7850. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 7850 has a 125 MHz higher core clock speed than the R9 280X and the same number of Render Output Units. This results in the HD 7850 providing 4 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 280X was released over a year more recently than the HD 7850, and so the R9 280X is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 7850.

The R9 280X has 2048 MB more video memory than the HD 7850, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the R9 280X also has superior memory performance overall.

The R9 280X has 134.4 GB/sec greater memory bandwidth than the HD 7850, which means that the memory performance of the R9 280X is massively better than the HD 7850.

The Radeon R9 280X XFX Double D 3GB Edition has 2048 Shader Processing Units and the Radeon HD 7850 XFX Ultra OC Edition has 1024. However, the actual shader performance of the R9 280X is 1741 and the actual shader performance of the HD 7850 is 849. The R9 280X having 892 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 280X delivers a massively smoother and more efficient experience when processing graphical data than the HD 7850.

The Radeon R9 280X XFX Double D 3GB Edition requires 250 Watts to run but there is no entry for the Radeon HD 7850 XFX Ultra OC Edition. We would recommend a PSU with at least 750 Watts for the R9 280X and a PSU with at least 500 Watts for the HD 7850. The R9 280X has been recommended a PSU with 250 Watts more than the HD 7850. The difference is significant enough that the R9 280X may have an adverse affect on your yearly electricity bills in comparison to the HD 7850.

GPU Mini Review

Mini ReviewRadeon R9 280X XFX Double D 3GB Edition is a special edition of the high-end Radeon R9 280X.

Radeon R9 280X XFX Double D 3GB Edition does not come overclocked out of the box. Therefore, it offers exactly the same performance the reference AMD Radeon R9 280X does.
Radeon HD 7850 XFX Ultra OC Edition is a special edition of the powerful Radeon HD 7850. See the standard version for more information about it.
The differences include an increase on the core-clock that went from 860MHz to 975MHz.
Benchmarks indicate a 7% boost when compared to the standard edition.
