In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 6870 are marginally better than the AMD Radeon HD 5850 XFX Black 1GB Edition.

The Radeon HD 6870 has a 135 MHz higher core clock speed than the HD 5850, but the HD 5850 has 16 more Texture Mapping Units than the Radeon HD 6870. As a result, the HD 5850 exhibits a 4.7 GTexel/s better Texture Fill Rate than the Radeon HD 6870. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The Radeon HD 6870 has a 135 MHz higher core clock speed than the HD 5850 and the same number of Render Output Units. This results in the Radeon HD 6870 providing 4.3 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 6870 was released less than a year after the HD 5850, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The Radeon HD 5850 XFX Black 1GB Edition and the Radeon HD 6870 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The HD 5850 has 9.6 GB/sec greater memory bandwidth than the Radeon HD 6870, which means that the memory performance of the HD 5850 is marginally better than the Radeon HD 6870.

The Radeon HD 5850 XFX Black 1GB Edition has 1440 Shader Processing Units and the Radeon HD 6870 has 1120. However, the actual shader performance of the HD 5850 is 551 and the actual shader performance of the Radeon HD 6870 is 504. The HD 5850 having 47 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 5850 delivers a marginally smoother and more efficient experience when processing graphical data than the Radeon HD 6870.

The Radeon HD 5850 XFX Black 1GB Edition requires 151 Watts to run and the Radeon HD 6870 requires 151 Watts. We would recommend a PSU with at least 500 Watts for the HD 5850 and a PSU with at least 500 Watts for the Radeon HD 6870. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

GPU Mini Review

Mini ReviewOverview
Radeon HD 5850 XFX Black 1GB Edition is a special edition of AMD's High-End Radeon HD 5850 1GB, created by XFX.

Overclock Out of The Box
The Central Unit now runs at 765MHz, instead of 725MHz while the Memory Clock is now of 1125MHz.

Cooling Solution
The Cooling System has been replaced by XFX's custom-designed Thermal Design, meaning the Graphics Card runs cooler under load.

Benchmarks indicate a 6% performance over the reference Radeon HD 5850 1GB.
Radeon HD 6870 is a fast high-end card made in 40nm fabrification process. It is based on the Barts XT architecure. Featuring 1120 Shaders, 56 texture units and 32 ROPs paired with fast 1GB GDDR5 video memory working on 1050 MHz, and core clock running at 900 MHz. Most latest games will be playable on High-Ultra and no AA with 1080p, except Demanding ones such as Far Cry 3 or Assassins Creed 3, which requires lowering settings to high, without Anti-Aliasing, while Crysis 3 needs medium-high graphical settings in order to achieve playable FPS.
