At the same time, SAPPHIRE is introducing a high performance model, the SAPPHIRE HD 7770 GHz OC Edition, which is factory overclocked to 1150 MHz core and 1250MHz memory (5Gb/s effective). Both models have a SAPPHIRE original single fan heatpipe cooler. For the more budget conscious, the third model in the series is the SAPPHIRE HD 7750, which shares all the features of the HD 7770 version, except that it ships with the lower core clocks of 800MHz and different output configuration as well as a lower Stream processor count.

SAPPHIRE will also be bundling an overclocking tool, TriXX, which allows the tuning of GPU voltage as well as core and memory clocks, whilst continuously displaying temperature. Manual control of fan speed is supported, as well as user created fan profiles and the ability to save up to four different performance settings.
