The new SAPPHIRE HD 6970 has the same internal architecture as the standard model, with 1536 stream processors & 96 texture processing units, & clock speeds are 880 M Hz for the core & 1375 Mhz (5.5 Gb/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, & 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 & 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 & 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 Tri XX up to a ceiling of 1500 M Hz core, 2000 M Hz memory.
