Gigabyte is readying a new passively-cooled Radeon HD 5770 graphics card called the Gigabyte HD 5770 Silent Cell, carrying model number GV-R577SL-1GD. This 100% non-reference design card is built using Gigabyte's Ultra Durable VGA technology (comprising of 2 oz copper PCB, ferrite-core chokes, Low RDS (on) MOSFETs, and binned high-performance memory chips. What's more peculiar is its large GPU cooler that covers the length and height of the card, and extends a couple of inches over the length of the card. At its end, the heatsink also extends a good couple of inches over the height of the card, some of its fins even protrude out of the rear panel. The heatsink is a densely-packed aluminum fin array to which heat is conveyed by four 6 mm thick heat pipes.

Cooling assembly aside, the card sticks to AMD reference clock speeds - 850 MHz core, 1200 MHz (4800 MHz effective) memory, and uses 1 GB of GDDR5 memory across a 128-bit wide memory interface. The 40 nm Juniper GPU packs 800 stream processors, and supports the latest PC graphics technologies including DirectX 11. The card can pair with up to three more of its kind for CrossFireX. Display connectivity options include one each of DVI, HDMI, and DisplayPort. Gigabyte did not give out a price.
