Palit is ready with what appears to be, a monstrous graphics card based on the ATI Radeon HD 4870 X2 (R700) design with 2 GB of GDDR5 memory, called the Palit Revolution R700 Deluxe. What makes it monstrous apparently is its width that spans across three expansion slots. Under the shroud of the cooler is an elaborate cooling system designed by Palit itself.

The cooler comprises of a large heat radiator, through which several heat-pipes conduct heat from contact blocks for the GPUs, memory, and the PCI-Express bridge chip, with seperate cooling blocks for the VRM area. Two fans of identical sizes blow air on the two thermal zones for the card: GPU and power circuitry.
