Sapphire Radeon HD 6770

The Sapphire Radeon HD 6770 pulls in a few frames ahead of the Radeon HD 5770. This is not to any surprise considering they are the same Juniper GPU, but the difference is that with the Sapphire model there's the stock 50MHz overclock to give it a slight advantage.

While it is a previous-generation component, the HD 6770 is a much faster GPU than the Turks-based HD 6570 graphics processor.

Interestingly, in some tests, the Sapphire Radeon HD 6770 falls slightly behind the reference HD 5770, but at least with the proprietary driver under Linux it is fast enough to not matter.
