Monday GIGABYTE announced the GV-R577SL-1GD, a new AMD Radeon HD 5770 graphics card featuring an internally-developed Ultra Durable VGA technology and Silent-cell cooling design. The latter technology provides a passive approach to cooling using four high-performance heat pipes and two additional fins. Encompassing the entire surface of the PCB, the cooling system resembles a car's radiator grille and looks quite impressive.
GIGABYTE said that--when compared to other cards--the Ultra Durable VGA Technology provides 10- to 30-percent more overclocking capabilities, 5- to 10-percent lower GPU temperatures, and "excellent" power efficiency, decreasing power switching loss by 10- to 30-percent. Ultra Durable VGA also features a 2 oz. copper PCB board, Samsung and Hynix memory, Japanese solid capacitor, Ferrite /Metal Core Chokes, and more.
With a core clock of 850 MHz and a memory clock of 4800 MHz, the new GIGABYTE card comes packed with 1GB of GDDR5 memory and support for DirectX 11, Eyefinity, Stream, CrossFireX, and more. Although the product is not yet available on the GIGABYTE website, more information can be obtained here. Unfortunately, pricing and availability was not provided.
