Radeon HD 7770 Sapphire Edition Game Requirement Analysis
Radeon HD 7770 Sapphire Edition is a special edition of the Radeon HD 7770 1GB GDDR5, which is a high-end GPU part of the Radeon HD 7000 Series released by AMD in 2011/2012.
We did not identify any OC nor any new relevant features. We believe the description provided by the manufacturer (Sapphire Technology Limited) is quite tricky since what is said to be included in the Radeon HD 7770 Sapphire Edition, is already included on the original edition from the start. Therefore, the performance should be exactly like the standard Radeon HD 7770.
The most demanding games will run on the highest settings but not at extreme resolutions (due to the limited memory size) and not paired with extremely demanding technologies like Tesselation (that require huge processing power). Modern, less demanding games, will run fluently at the highest settings possible.
