Radeon HD 7770 Sapphire GHz OC Edition Game Requirement Analysis
Radeon 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).
