In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7850 are noticeably better than the AMD Radeon R7 260.

The Radeon R7 260 has a 140 MHz higher core clock speed than the Radeon HD 7850, but the Radeon HD 7850 has 16 more Texture Mapping Units than the Radeon R7 260. As a result, the Radeon HD 7850 exhibits a 7 GTexel/s better Texture Fill Rate than the Radeon R7 260. 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 260 has a 140 MHz higher core clock speed than the Radeon HD 7850, but the Radeon HD 7850 has 16 more Render Output Units than the Radeon R7 260. As a result, the Radeon HD 7850 exhibits a 11.5 GPixel/s better Pixel Fill Rate than the Radeon R7 260. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Radeon R7 260 was released over a year more recently than the Radeon HD 7850, and so the Radeon R7 260 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Radeon HD 7850.

The Radeon R7 260 and the Radeon HD 7850 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The Radeon HD 7850 has 57.6 GB/sec greater memory bandwidth than the Radeon R7 260, which means that the memory performance of the Radeon HD 7850 is much better than the Radeon R7 260.

The Radeon R7 260 has 768 Shader Processing Units and the Radeon HD 7850 has 1024. However, the actual shader performance of the Radeon R7 260 is 653 and the actual shader performance of the Radeon HD 7850 is 749. The Radeon HD 7850 having 96 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon HD 7850 delivers a significantly smoother and more efficient experience when processing graphical data than the Radeon R7 260.

The Radeon R7 260 requires 95 Watts to run and the Radeon HD 7850 requires 130 Watts. We would recommend a PSU with at least 450 Watts for the Radeon R7 260 and a PSU with at least 500 Watts for the Radeon HD 7850. The Radeon HD 7850 requires 35 Watts more than the Radeon R7 260 to run. The difference is significant enough that the Radeon HD 7850 may have a slight adverse affect on your yearly electricity bills in comparison to the Radeon R7 260.

GPU Mini Review

Mini ReviewRadeon R7 260 is a fast-middle-class graphics card based on the Second Revision of the GCN architecture. It packs a Core codenamed Bonaire PRO.
The Bonaire PRO is a cut-down version of the Bonaire XT Core used on Radeon HD 7790. It comes with 14 Compute Units and thus offers 768 Shader Processing Units, 48 TMUs and 16 ROPs. This, on a 128-bit memory interface of fast GDDR5. Compared to the Bonaire XT Core, it has support for DirectX 11.2 and has support for AMD's TrueAudio Technology.
Benchmarks indicate its performance is around 10% slower than Radeon HD 7790 and a little over that when taking Radeon R7 260X as a reference.
The card proves to be very inefficient seeing as it has a higher rated TDP board than Radeon HD 7790 and its release price of $109 makes Radeon HD 7850 a better option.
Radeon HD 7850 is a high-end GPU based on 28nm GCN architecture.
It's based on the Pitcairn Core (Pro variant) and therefore offers 1024 Shader Processing Units, 64 TMUs and 32 ROPs on a 256-bit interface of fast GDDR5. The central unit is clocked at 860MHz while the memory clock operates at 1200MHZ.
It offers great performance, almost on level with previously acclaimed Radeon HD 6970. Therefore, most demanding games are playable at the highest settings with fluent frame rates, using a 1080p resolution.
Radeon HD 7850 was elected the best GPU of 2012 by the GD community, thanks to its accessible price and outstanding performance.
