Marketing Information

The new SAPPHIRE HD 6970 has the same internal architecture as the standard model, with 1536 stream processors and 96 texture processing units, and clock speeds are 880MHz for the core and 1375Mhz (5.5Gb/sec effective) for the 2GB of GDDR5 memory. This new design has two 90mm fans with thin impellers that can move the same amount of air at 10% lower rotation speeds than conventional fans, keeping noise low, and their special dust repelling bearings contribute to high reliability.
With the Dual BIOs set to the standard position, the Dual fans keep this model quiet and up to 25% cooler than the standard model even under load conditions. With the BIOS switched to the performance setting, the core voltage of the GPU is raised to 1.2V, the fan speed is set to a high performance profile and the powertune adjustment for overclocking is raised to 50% allowing the user to maximise performance of the card by increasing clock speeds either with AMD Overdrive or with SAPPHIRE TriXX up to a ceiling of 1500MHz core, 2000MHz memory.
