Gigabyte has just unveiled their second factory overclocked graphics card, the Radeon HD 6970 OC2 (codenamed GV-R697OC2-2GD). he card makes use of the same exact Ultra Durable VGA+ PCB used on the GV-R697OC-2GD, as well as the WindForce-3X cooler, but comes with higher clock speeds of 920 MHz core and 1375 MHz (5.50 GHz GDDR5 effective) memory; compared to 900/1375 (5500) MHz on the GV-R697OC-2GD, and 880/1375 (5500). In all three cases, Gigabyte didn’t tinker with memory clock speeds.
The PCB makes use of 2 oz copper layer, and high grade components such as ferrite-core chokes and Japanese capacitors. Its cooler uses a large heat pipe-fed aluminum fin array ventilated by three 80 mm fans. Based on the 40 nm “Cayman” silicon, the Radeon HD 6790 packs 1536 VLIW4 stream processors, and a 256-bit wide high-speed GDDR5 memory interface.
Unfortunately there is no pricing information at this moment.
