Passively cooled HD 4770 by Gigabyte

Last week, we saw PowerColor as one of the first manufacturers to introduce an AMD Radeon HD 4770 based graphics card with a complete passive cooling system. As of yet, Gigabyte has also shown its silenced version of the 40nm RV740 chip, equipped with the "Silent Cell" cooling block. Three copper heatpipes and quite a few aluminum fins are to provide enough cooling so that the GV-R477SL-1GI can do it's job completely soundless. We saw the same cooler on the GV-N92TSL-1GI earlier, that card was based on nVidia's GeForce 9800 GT chip.

Like the other Radeon HD 4770 graphics cards, the chip will feature 640 stream processors and the same 128-bit memory interface. Gigabyte has doubled that amount of GDDR5-memory to 1 GB and has placed a D-Sub, DVI- and HDMI-connector on the card.

As of yet, there's no information available regarding clock frequencies and a pricetag of the passively cooled GPU.
