Marketing Information

The SAPPHIRE HD 7790 2GB OC Edition has 2GB of the latest DDR5 memory and is factory overclocked, with core clocks of 1050MHz and memory clocks of 1600MHz (6.4GB/s effective), to deliver new levels of performance in its price segment. Performance is optimised with the latest version of AMD's PowerTune technology.

The 2GB board features a new cooler design, which uses a dual heatpipe system and a single aerofoil section fan assembly with dust repelling bearings for maximum efficiency and reliability. A unique and SAPPHIRE original feature is the integration into the cooling system of the metal backplate which cools the memory chips on the reverse side of the pcb and helps with pcb rigidity. A finned heatsink attached to the backplate passes through the pcb and extends into the airflow from the fan on the front side of the card, enabling the airflow to carry away the heat from the components on the back of the pcb and reducing memory temperatures to as low as 13 C.
