My DDR3-2400CL9 is 7.5ns. I had some old DDR2 PIs that were 6.7ns (1200CL4). I think overall latency is getting worse. At least density and power draw is getting better though.So what? Memory timing increase proportionally with the speed. CAS latency and true latency are 2 completelly different things.
Please read this article to understand in more details:
As you can see, the Speed and Clock Cycle time are the ones that matter, not CAS timings. The bigger the frequency, the lesser Clock Cycle time is.
true latency (ns) = clock cycle time (ns) x number of clock cycles (CL)
The latest DDR4-4000Mhz have a true latency of 8.911ns.
