Neoseeker has published a combination review and comparison of DDR3 vs
DDR2. This is a review of both Asus' P5K3 DDR3 P35 based board, and
a review of Corsair's TWIN3X2048-1333C9DHX DDR4 1333MHz memory. They
took the Asus and Corsair and overclocked them to the very
limit of what the RAM could take, and compared it against DDR2.
You'd be surprised how well DDR3 stacks up!
"Basically, as a simple example, if you had DDR2-667 memory with
5-5-5-15 timing, that would have exactly the same latency as DDR3-1333
memory with 10-10-10-30 timing, as the latency clock cycles had to go
up to compensate for the higher transfer rates because there is no
magic. DDR3 is basically DDR2 with an extra level of interleaving on the
memory modules, and just because it can clock out the data faster, it
does not mean that they managed to increase the basic RAS, CAS and
other latencies... and since they are now specified relative to a
higher speed clock, the number of cycles for specifying latencies get
