Back when DDR5 was brand new the lowest CAS was 40, then 38, 36 and now at 30 which is where I bought in as they aren't expected to lower much more if any.

I’ll be genuinely surprised if by the end of the DDR5 era we don’t have 6000/24 kits, possibly pushing better. A jump from 7ns to 10ns as best case first word latency would be unusual. We normally don’t lose more than 1ns between generations, and it’s usually a wash.

Now, how much that difference matters in the real world is a larger point of debate, and would be very task specific.
