Overclocking PerformanceThe Radeon HD 5770 received a core frequency boost of 9.5%, while the memory saw a rise of 17%. We used the Catalyst Control Panel for overclocking which provided headroom for greater frequencies. However we were unable to achieve stable performance beyond a core clock of 930MHz and 1400MHz for the memory.
Resident Evil 5 saw decent performance gains with the Radeon HD 5770 rendering an additional 4-7 additional frames per second on average depending on the resolution. This small performance gain (5-10%) allowed the Radeon HD 5770 to leap frog the Radeon HD 4870 and GeForce GTX 260 by tiny margins in the Resident Evil test.
