G.Skill Ripjaws S5 DDR5-6800 2x16GB vs Patriot Viper Venom DDR5-6400 2x16GB in detail
True latency
Both kits land on 10.00 ns. G.Skill Ripjaws S5 DDR5-6800 2x16GB gets there at 6800 MT/s at CL34, Patriot Viper Venom DDR5-6400 2x16GB at 6400 MT/s at CL32. CAS latency counts clock cycles rather than time, so a higher clock paired with a looser CAS number arrives at the same place — which is why these two spec sheets look different and the memory does not.
Transfer rate
G.Skill Ripjaws S5 DDR5-6800 2x16GB carries the higher rating, 6800 MT/s to 6400 MT/s for Patriot Viper Venom DDR5-6400 2x16GB — 54400 MB/s per module against 51200 MB/s. That is peak transfer rate, not access time: a higher clock is reached by counting more cycles for each access, which is why the CAS numbers differ too and why the true latency above is the directly comparable figure.
