Card makers to strap GDDR4 RAM on the Radeon 3870 X2

— 5:06 PM on January 30, 2008

The official set of specifications for AMD's newly released Radeon HD 3870 X2 mandate the use of GDDR3 memory clocked at 900MHz, which already gives the dual-GPU card plenty of bandwidth. However, according to the guys at Fudzilla, some of AMD's partners plan to kick things up a notch by trading in that memory for something a little faster.

Fudzilla explains that 3870 X2s outfitted GDDR4 memory should start to show up "in a few weeks." The cards should have more memory bandwidth and possibly lower power utilization than the existing model, although Fudzilla doesn't say what the impact on performance will be. Nonetheless, folks can obviously expect to pay a bit extra for the GDDR4 variants compared to their current GDDR3 siblings, whose e-tail prices start at AMD's official list figure of $449.
