Speed is how fast it can process stuff and latency is how long per cycle it has to wait to process things thing thats about right here check this thread out will explain better:

In general the faster RAM is the higher the latency will be. The first number or the CAS latency is the biggest factor of its performance as far as timings go. I always say go for higher speed and if you cant use it all with your overclock lower the speed and try to tighten timings.

There are two main things to consider when buying ram: bandwidth and timings. 1333mhz @ 7-7-7 timings aren't that great because you'll be limited when you try to overclock your cpu. Most people balance it at 1600mhz @ 8-8-8 or 9-9-9 timings because of the higher bandwidth.
