GDDR 5 to come to graphics cards next year

Samsung has announced plans to mass produce GDDR 5 memory for graphics cards, which will be faster and more energy efficient that current memory.

GDDR 5 (Graphics Double Data Rate) will run on 1.5V and according to Samsung will be able to transfer data at speeds up to 6Gbps (bits per second), which is an improvement over the 3.2Gbps transfer rates offered by GDDR 4 and a massive gain compared to the puny 1.6Gbps transfer rate of GDDR 3.

Samsung plans to have mass production up to speed by mid-2008.

I wonder if this announcement has anything to do with the rumor that nVIDIA plans to launch a new G9 flagship product in February 2008.  GDDR 5 would certainly help give the company the upper hand against ATI.
