The new SAPPHIRE HD 7800 series of graphics cards is based on the third family of GPU's from AMD built in its new 28nm process and featuring the highly acclaimed GCN graphics processing architecture. The new HD 7870 and HD 7850 GPUs have an optimised internal structure sharing many of the features of the high performance HD 7900 series already released but with fewer Stream processors and a new high speed 256-bit memory interface to the latest DDR5 memory types. It is aimed at mainstream gamers looking for excellent performance together with good value and all the latest features.

Two models of the HD 7870 are being introduced by SAPPHIRE at launch. The first is the SAPPHIRE HD 7870 which will ship with a core clock speed of 1GHz, and will be known as the SAPPHIRE HD 7870 GHz Edition. It is equipped with 2GB of the latest DDR5 memory clocked at 1200MHz (4.8Gb/s effective). At the same time SAPPHIRE is introducing a higher performance model, the SAPPHIRE HD 7870 GHz OC Edition, in which both core and memory are factory overclocked and the PowerTune limits are raised to allow even further performance tuning. Both models are equipped with SAPPHIRE's new dual-extractor technology - Dual-X - a highly efficient multi-heatpipe cooler with dual fans providing quiet and very cool operation during normal operating conditions, and superb cooling performance even under extreme load.
