Latency is a temporal feature .... where as clock is quantized.

For example, latency for DDR2-1067 C5 is lower than DDR2-800 C4 ...

4* 1/800 = 5 ns latency

5* 1/1067 = 4.68 ns latency

It depends on the memory,

DDR3-1333 C7 (which is common, though expensive) is 5.25 ns
DDR3-2000 C9 (which is also common) is 4.5 ns latency

These are per transaction, there are other latencies that bring the total up quite substantially.

Though, Shintai is correct, large caches and good prefetchers hide some of that latency overall, to the point that it is not a huge concern.

Overall, dual channel DDR3-2000 C9 will out perform DDR2-800 C4 latency wise, and C8 will be outstanding ram.

C8 of course will be the uber, uber expensive stuff: http://www.newegg.com/Product/Produc...82E16820145210
