GDDR4: Samsung Has Started The Production

Samsung has announced to have launched the production of the next generation graphic card-dedicated RAM chips: GDDR4.
Those modules will have data speed transfer reaching 2.4Gbits/s at 32 bits vs. 2.0Gbits/s for the current GDDR3. If the difference is not impressive, the main feature of the GDDR4 is its low power consumption level that can be up to 45% lower. This is achieved thanks to a thinner engraving process (80nm), and as a consequence it will also be easier to cool down GDDR4 chips.
The first graphic cards based on GDDR4 should be available by the end of the year.
