In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R7 260 are significantly better than the AMD Radeon HD 6770 Sapphire 1GB Edition.

The Radeon R7 260 has a 150 MHz higher core clock speed and 8 more Texture Mapping Units than the 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 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 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 HD 6770.

The Radeon R7 260 has 1024 MB more video memory than the 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 HD 6770, which means that the memory performance of the Radeon R7 260 is slightly better than the HD 6770.

The Radeon HD 6770 Sapphire 1GB Edition has 800 Shader Processing Units and the Radeon R7 260 has 768. However, the actual shader performance of the HD 6770 is 340 and the actual shader performance of the Radeon R7 260 is 653. 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 HD 6770.

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

The Radeon HD 6770 Sapphire 1GB Edition requires 108 Watts to run and the Radeon R7 260 requires 95 Watts. We would recommend a PSU with at least 500 Watts for the HD 6770 and a PSU with at least 450 Watts for the Radeon R7 260. The HD 6770 requires 13 Watts more than the Radeon R7 260 to run. The difference is not significant enough for the HD 6770 to have a noticeably larger impact on your yearly electricity bills than the Radeon R7 260.

GPU Mini Review

Mini ReviewOverview
Radeon HD 6770 Sapphire 1GB Edition is a special edition of AMD's fast-middle-class Radeon HD 6770. It is a reference card as it features a new Cooling Solution but no overclocking out of the box. Read below to know more.

Overclock Out of The Box
The Central Unit remains clocked at 850MHz and the Memory Clock still operates at 1200MHz.

Cooling Solution
The reference AMD Single-Fan Cooling System has been replaced by Sapphire's Large Single Fan Cooling Solution. This means the card runs cooler under load.

Power Consumption
The Rated Board TDP should remain the same: 108W. We recommend a 500W PSU with one available 6-pin connector.

Release Price
Not available.

Performance
Radeon HD 6770 Sapphire 1GB Edition offers exactly the same performance the reference card does.
Radeon 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.
