The new dynamic duo duke it out

In one corner ... the reigning champion, DDR2! In the other, a newcomer to the ring, DDR3! They will be battling on a P5K Deluxe WiFi AP and a P5K3 Deluxe WiFi AP, which is as close a match of boards as Neoseeker could find. These two combatants battle through artificial and real world benchmarks, and a gamut of clock speeds and timings. The upstart seems to be the underdog going in, but is that really the case.
"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 larger."
