DDR3 SDRAM or double-data-rate three synchronous dynamic random access memory is the name of the new DDR memory standard that is being developed as the successor to DDR2 SDRAM
these modules could transfer data at the effective clockrate of 800-1600MHz (for a single clock bandwidth of 400-800MHz), compared to DDR2's current range of 400-1066 MHz (200-533 MHz) or DDR's range of 200-600 MHz (100-300 MHz
Advantages compared to DDR2
* Higher bandwidth (up to 1600 MHz)
* Performance increase at low power
* Longer battery life in laptops
* Enhanced low power features and thermal design
Intel will launch its latest mother boards based on the soon to be relased new chipset with DDR3 support.
However i don't find any usefullness in this change. Just another monopolising action by Intel. Currently DDR2 arn't stable yet, why don't they spend more on R&D on that part.
