AMD prepares the version radeon HD 3870 X2 with GDDR-4 memory , which is based on faster revision RV670 chip and more compact revision PLX bridge, which supports PCI express 2.0. This combination allow to decrease the amounts of printed-circuit board.
AMD Partners try to save on memory with the production Of radeon HD 3870, after equipping this video card with GDDR- 3 microcircuits . PowerColor released the version radeon HD 3870 with cooler zEROtherm but here with only 512 mb GDDR-4 memory and 800/2340 MHz frequencies .
Today in Chinese stores appeared the radeon HD 3870 with GDDR- 3 memory , which is equipped with the same cooler , but operates at frequencies 777/1800 MHz.
