Asus has released its latest AMD Radeon card, the HD 6770 DirectCU Silent, priced at Rs. 9,750 (MRP) in India. According to Asus, the HD 6770 DirectCU Silent card delivers zero decibel performance, using a new fanless design that apparently makes it the coolest passive cooling GPU in the market – up to 16% cooler than conventional passive cooling designs.
Previous Asus cards to feature the DirectCU Silent design, with its 95% larger heatsinks, include the GT 430, GT 440, GTS 450 and HD 6670. The HD 6770 until recently was an OEM-only card, and is essentially a rebadged version of the HD 5770, with a different BIOS, HDMI 1.4a support, and UVD3 video decoding that allows it to process even Blu-ray 3D.
Falling in the performance mainstream category, between Nvidia’s GTS 450 and GT 430, the Asus HD 6770 DirectCU Silent card features a Juniper GPU with 1.04 billion transistors, 1GB of GDDR5 video memory, 800 stream processors, 16 ROPs, a 850MHz core clock, 1.2GHz memory clock, 128-bit memory bandwidth, and 40 texture units. According to Asus, the design uses the company’s exclusive Super Alloy Power components, which offer a 15% performance boost and 2.5x longer product lifespan.
