DDR3 - How is this different to DDR2?
Double-data-rate - three synchronous dynamic random access memory
This page is not meant to be a re-hash of the WikiP page - the information there is more likely to be far more informed! The discussion here is how does DDR3 compare to its predesesor? Is is desirable for use in "general purpose" notebooks (i.e. not high-end gaming machines)? Does it offer power saving for portable devices? How does it play with HyperTransport?
DDR3 is inherently faster than DDR2 but not necassarily better in all applications due to the compatabilty of the platform it is used and the latentcy that is asssociated with its operation. The Intel Centrino 2 platform describes the compatability with DDR3 memory.
Apparently there is some confusion in the terminology used by GPU manufacteres than also claim to use DRR3 in their "high-end" video adapters. Fast bus communication is required in these GPUs but the DDR3 technology may be different - see the WikiP pages and the Nvidia and ATI details for more information in this regard.
