In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7770 Sapphire GHz OC Edition are marginally better than the AMD FirePro V7900.

The HD 7770 was released less than a year after the FirePro V7900, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The FirePro V7900 has 1024 MB more video memory than the HD 7770, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the FirePro V7900 also has superior memory performance overall.

The FirePro V7900 has 80 GB/sec greater memory bandwidth than the HD 7770, which means that the memory performance of the FirePro V7900 is much better than the HD 7770.

The Radeon HD 7770 Sapphire GHz OC Edition has 640 Shader Processing Units and the FirePro V7900 has 1280. However, the actual shader performance of the HD 7770 is 626 and the actual shader performance of the FirePro V7900 is 603. The HD 7770 having 23 better shader performance is not particularly notable, as altogether the FirePro V7900 performs better when taking into account other relevant data.

The Radeon HD 7770 Sapphire GHz OC Edition requires 80 Watts to run and the FirePro V7900 requires 150 Watts. We would recommend a PSU with at least 450 Watts for the HD 7770. The FirePro V7900 requires 70 Watts more than the HD 7770 to run. The difference is significant enough that the FirePro V7900 may have an adverse affect on your yearly electricity bills in comparison to the HD 7770.

GPU Mini Review

Mini ReviewRadeon HD 7770 Sapphire GHz OC Edition is a special edition of the fast-middle-class Radeon HD 7770. See the standard version for more information about it.
The differences include increased memory and core clocks, from 1125MHz to 1250MHz and from 1000MHz to 1150MHz, respectively. A new quiet and efficient cooling system is also available.
Benchmarks indicate a 9,5% performance boost when compared to the standard Radeon HD 7770.
Benchmarks indicate that the most demanding games (e.g. Metro 2033) will run at the highest settings but not at extreme resolutions (due to the limited memory size).
The AMD FirePro V7900 professional graphics delivers incredible performance, superb visual quality, and outstanding multi-display capabilities all in a single-slot solution. It is an excellent solution for professionals who work with advanced visualization, complex models, and large data sets. <\br> The AMD FirePro V7900 features incredible multi-display capability with AMD Eyefinity technology support for four simultaneous and independent monitors from a single graphics card. Also, the AMD FirePro V7900 is backed by 2GB of ultra-fast GDDR5 memory and 1280 stream processors.
