Powercolor HD 4870 1GB GDDR5 has awesome VRM
PowerColor is going to launch HD 4870 1GB GDDR5. Weve got some more pics of the card.
The card uses AMD reference PCB but changed memory chips and VRM. A reference HD 4870 uses 3 phase VRM for GPU and 2 phase for memory. Powercolor uses better digital VRM chips, supply GPU with 4 phase digital VRM.
The cooler they used is form a Korean company ZEROtherm. The cooler uses only two heatpipes so we still not sure if it can cool down the hot RV770 effectively.
Currently no word on price and release date, but PowerColor promises us the card will be a factory OC card.
The cooler can help cooling memory as well
