The SAPPHIRE HD 7970 OC Edition features 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. The HD 7970 from AMD is the most powerful single chip GPU ever built - it has a new internal structure with 32 compute units and a total of 2048 Stream processors. The SAPPHIRE HD 7970 OC Edition ships with a raised core clock speed of 950MHz, and 1425MHz for the memory. Its Dual BIOS switch allows users to select the higher performance settings of 1GHz core and 1450MHz memory, making the fastest card in its class. This setting also uses a more aggressive fan profile and raises the limits for maximum overclocking.
