GIGABYTE rolled out a pair of Radeon HD 7790 graphics cards, the GV-R779-1GI, which sticks to AMD reference clock speeds of 1000 MHz core and 6000 MHz memory, and the factory-overclocked GV-R779OC-1GI, featuring 1075 MHz core, and 6400 MHz memory. The two offer GIGABYTE's UltraDurable VGA PCB, and its Triangle Cool fan-heatsink that pairs a large 100 mm fan to a copper-embedded aluminum heatsink. Based on the 28 nm "Bonaire" silicon, the Radeon HD 7790 packs 896 stream processors, dual tessellation units, 56 TMUs, 16 ROPs, and a 128-bit GDDR5 memory interface holding 1 GB of memory; and a brand new dynamic-clock technology. The base model is priced at US $149.99, and the OC model at $159.99.
