In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R7 260 are significantly better than the AMD Radeon HD 6770.

The Radeon R7 260 has a 150 MHz higher core clock speed and 8 more Texture Mapping Units than the Radeon HD 6770. This results in the Radeon R7 260 providing 14 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 260 has a 150 MHz higher core clock speed than the Radeon HD 6770 and the same number of Render Output Units. This results in the Radeon R7 260 providing 2.4 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 Radeon R7 260 was released over a year more recently than the Radeon HD 6770, 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 6770.

The Radeon R7 260 has 1024 MB more video memory than the Radeon HD 6770, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the Radeon R7 260 also has superior memory performance overall.

The Radeon R7 260 has 19.2 GB/sec greater memory bandwidth than the Radeon HD 6770, which means that the memory performance of the Radeon R7 260 is slightly better than the Radeon HD 6770.

The Radeon R7 260 has 768 Shader Processing Units and the Radeon HD 6770 has 800. However, the actual shader performance of the Radeon R7 260 is 653 and the actual shader performance of the Radeon HD 6770 is 340. The Radeon R7 260 having 313 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon R7 260 delivers a noticeably smoother and more efficient experience when processing graphical data than the Radeon HD 6770.

The Radeon R7 260 transistor size technology is 12 nm (nanometers) smaller than the Radeon HD 6770. This means that the Radeon R7 260 is expected to run slightly cooler and achieve higher clock frequencies than the Radeon HD 6770.

The Radeon R7 260 requires 95 Watts to run and the Radeon HD 6770 requires 108 Watts. We would recommend a PSU with at least 450 Watts for the Radeon R7 260 and a PSU with at least 450 Watts for the Radeon HD 6770. The Radeon HD 6770 requires 13 Watts more than the Radeon R7 260 to run. The difference is not significant enough for the Radeon HD 6770 to have a noticeably larger impact on your yearly electricity bills than 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 6770 is fast-middle-class graphics solution, based on 40nm. It is based on JuniperXT architecture. It features 800 Shaders 16 ROPs, 40TMUs on 128 bit memory bus of fast GDDR5 running at 1200MHz and Core clock runs at 850MHz. 6770 is renamed 5770 with Open GL 4.1 support and small UVD tweaks. Latest games will run fluently on High graphics settings aside Crysis 3 which requires medium details in order to be playable on 1080p. Most suitable CPU match would be high-end dual core such as i3 or better.
