The SAPPHIRE HD 5970 OC Edition ships with enhanced clock speeds of 735MHz core and 1010MHz (4.04GHz effective) - faster than the standard model, making the SAPPHIRE HD 5970 OC the fastest card in its class, and the fastest in the world*. Enthusiasts will also be able to tune performance of these SAPPHIRE cards using the SAPPHIRE Redline voltage tweaker tool** to enable higher levels of overclocking.With 2GB of fifth generation GDDR5 memory and a new architecture with a total of 3200 stream processors and 160 texture units the SAPPHIRE HD 5970 OC is lightning fast with existing DirectX10.1, DirectX 10 and DirectX 9.0 games and applications, and will support stunning new levels of detail, transparency and lighting effects in new releases of software using DirectX 11. All of this comes with a modest active power consumption and ATI Powerplay Dynamic Power Management to achieve super-low power consumption in 2D and idle modes.

These cards incorporate the latest architectural features from the ATI division of AMD in order to fully support Microsoft DirectX 11, including DirectCompute 11 instructions, hardware Tessellation and multi-threaded communications with the system CPU. These combine to provide new capabilities such as the interaction between transparent objects, new lighting and accelerated post processing effects as well as supporting ATI Stream for accelerating applications such as video transcoding.
