Sapphire HD7770 Vapor X Overclock Edition Review

To overclock we used Catalyst Control Center today.

We managed to push the Sapphire HD7770 core from 1,100mhz to 1,230mhz. The GDDR5 memory could be increased from 1,300mhz to 1,445mhz (5,780mhz effective).

The additional overclock increased the 3DMark 11 score from 3,732 points to 4,131 points. Not a huge increase, but the hardware is predominately bandwidth limited.
