In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 5870 1024MB are very slightly better than the AMD Radeon HD 5850 XFX Black 1GB Edition.

The HD 5870 has a 85 MHz higher core clock speed and 8 more Texture Mapping Units than the HD 5850. This results in the HD 5870 providing 12.9 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 HD 5870 has a 85 MHz higher core clock speed than the HD 5850 and the same number of Render Output Units. This results in the HD 5870 providing 2.7 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 HD 5850 was released less than a year after the HD 5870, 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 5870 1024MB have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The HD 5870 has 9.6 GB/sec greater memory bandwidth than the HD 5850, which means that the memory performance of the HD 5870 is marginally better than the HD 5850.

The Radeon HD 5850 XFX Black 1GB Edition has 1440 Shader Processing Units and the Radeon HD 5870 1024MB has 1600. However, the actual shader performance of the HD 5850 is 551 and the actual shader performance of the HD 5870 is 680. The HD 5870 having 129 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 5870 delivers a slightly smoother and more efficient experience when processing graphical data than the HD 5850.

The Radeon HD 5850 XFX Black 1GB Edition requires 151 Watts to run and the Radeon HD 5870 1024MB requires 188 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 HD 5870. The HD 5870 requires 37 Watts more than the HD 5850 to run. The difference is significant enough that the HD 5870 may have a slight adverse affect on your yearly electricity bills in comparison to the HD 5850.

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.

Performance
Benchmarks indicate a 6% performance over the reference Radeon HD 5850 1GB.
Radeon HD 5870 1024MB is a High-End GPU part of the Evergreen HD 5000 family. HD 5870 wears the Cypress XT, which allows for 1600 Shader Processing Units, 80 TMUs and 32 ROPs. The Texture units increase from the Cypress Pro HD 5850 chip improves HD 5870 Filtering capabilities, while still mantaining the 256-bit Memory interface on GDDR5. Most modern demanding games will run on Ultra settings on Full HD, whereas really demanding games such as Crysis 3 and Far Cry 3 will require lowered Aliasing settings in order to achieve fluent FPS on 1080p. Power draw is rather overwhelming, and gamers looking to get this GPU will need a decent 500W PSU with two PCIe connectors.
