In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R7 260X are very slightly better than the AMD Radeon HD 5850 XFX Black 1GB Edition.

The Radeon R7 260X has a 335 MHz higher core clock speed but 16 fewer Texture Mapping Units than the HD 5850. The lower TMU count doesn't matter, though, as altogether the Radeon R7 260X manages to provide 6.5 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 Radeon R7 260X has a 335 MHz higher core clock speed than the HD 5850, but the HD 5850 has 16 more Render Output Units than the Radeon R7 260X. As a result, the HD 5850 exhibits a 6.9 GPixel/s better Pixel Fill Rate than the Radeon R7 260X. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Radeon R7 260X was released over three years more recently than the HD 5850, and so the Radeon R7 260X is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 5850 when running the latest games.

The Radeon R7 260X has 1024 MB more video memory than the HD 5850, 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 5850 has 40 GB/sec greater memory bandwidth than the Radeon R7 260X, which means that the memory performance of the HD 5850 is noticeably better than the Radeon R7 260X.

The Radeon HD 5850 XFX Black 1GB Edition has 1440 Shader Processing Units and the Radeon R7 260X has 896. However, the actual shader performance of the HD 5850 is 551 and the actual shader performance of the Radeon R7 260X is 838. The Radeon R7 260X having 287 better shader performance is not particularly notable, as altogether the HD 5850 performs better when taking into account other relevant data.

The Radeon R7 260X transistor size technology is 12 nm (nanometers) smaller than the HD 5850. This means that the Radeon R7 260X is expected to run slightly cooler and achieve higher clock frequencies than the HD 5850. While they exhibit similar graphical performance, the Radeon R7 260X should consume less power than the HD 5850.

The Radeon HD 5850 XFX Black 1GB Edition requires 151 Watts to run and the Radeon R7 260X requires 115 Watts. We would recommend a PSU with at least 500 Watts for the HD 5850 and a PSU with at least 450 Watts for the Radeon R7 260X. The HD 5850 requires 36 Watts more than the Radeon R7 260X to run. The difference is significant enough that the HD 5850 may have a slight adverse affect on your yearly electricity bills in comparison to the Radeon R7 260X.

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 R7 260X is a Fast-Middle-Class Graphics Card based on the Second Revision of the Graphics Core Next (GCN) Architecture.

Radeon R7 260X Equips a GPU Codenamed Bonaire XTX which is a Second Gen GCN GPU and is an upgraded version of the Bonaire XT GPU previously used on Radeon 7790.
Bonaire XT has 14 Compute Units activated and thus offers 896 Shader Processing Units, 56 TMUs and 16 ROPs.

The Central Unit is clocked at 1100MHz.

Memory: Speed
The GPU is equipped with fast GDDR5 and Accesses the Frame Buffer through a 128-bit Memory Interface. The Memory Clock Operates at 1625Hz.

Memory: Frame Buffer
The GPU can fill up a Memory Pool of up to 2GB. This would be useful were the Graphics Card suited for 1080p Gaming, which is not the case.

Power Consumption
With a rated board TDP of 115W, it requires at least a 500W PSU with one available 6-pin connector.

Radeon R7 260X is the Fastest of all Radeon R7 260X Variants and Delivers Performance almost up to 10% over the Older Radeon HD 7790.

System Suggestions
Radeon R7 260X is best suited for resolutions up to and including 1600x900. We recommend a Middle-Class Processor and 8GB of RAM for Optimal Performance.
