This of course ignores all other timings except CL but it's a very rude but correct base calculation. If you cannot get at least CL16 on 4000 it isn't worth it latency wise compared to 3000 CL12.
Higher frequency makes higher bandwidth and lower latency too. So you want high clocks, with low latency.
