Asus has recently updated its product portfolio to include a new passively cooled Radeon HD 6770 graphics card that uses its custom DirectCU design in order to deliver noise-free operation without sacrificing cooling and gaming performance.
As most of you already know, the Radeon HD 6770 is nothing more than a re-branded previous generation HD 5770, which has now received support for HD3D by including an HDMI 1.4a video output.
Otherwise, the card sports the same specifications as the Radeon HD 5770, meaning that it includes 800 streaming processors, 40 texturing units, 16 ROP units and a 128-bit memory bus, which is connected to 1GB of GDDR5 memory.
Moving to Asus' version of this graphics card, this is built around the DirectCU custom cooler that occupies two slots inside the system's case and employs four direct contact copper heatpipes to draw the heat away from the graphics core.
This is then driven into a large aluminum heatsink, which exceeds the card's PCB and requires users to carefully measure the space available inside the system's case before trying to fit the HD 6770 DirectCU Silent.
Unfortunately, Asus hasn't disclosed any information regarding the clock speeds of this solution, but it is expected to use AMD's stock operating frequencies which are set at 850MHz core and 1.200MHz (408GHz effective) memory.
In addition to the DirectCU cooling system, Asus' creation will also feature the Super Alloy Power technology for its capacitors, chokes and MOSFETs, which the company states it can offer 2.5 times longer lifespan than AMD's reference design.
On the rear bracket, users will find the usual assortment of video outputs that include VGA, DVI and HDMI ports.
