Kingston FURY Beast DDR5-6400 2x16GB vs Patriot Viper Xtreme 5 DDR5-8000 2x16GB 8200 CL38 in detail
True latency
Patriot Viper Xtreme 5 DDR5-8000 2x16GB 8200 CL38 is the lower-latency kit at 9.27 ns, against 10.00 ns for Kingston FURY Beast DDR5-6400 2x16GB — a difference of 0.73 ns. That figure is what reconciles the two spec sheets: CAS latency counts clock cycles, so it only means something next to the clock it counts. Kingston FURY Beast DDR5-6400 2x16GB runs 6400 MT/s at CL32; Patriot Viper Xtreme 5 DDR5-8000 2x16GB 8200 CL38 runs 8200 MT/s at CL38.
Transfer rate
Patriot Viper Xtreme 5 DDR5-8000 2x16GB 8200 CL38 is rated 8200 MT/s against 6400 MT/s for Kingston FURY Beast DDR5-6400 2x16GB — 65600 MB/s per module, against 51200 MB/s. That is peak transfer rate, not access time: reaching a higher clock costs more cycles on each access, which is why the CAS numbers differ too, and why the true latency above is the figure that compares directly.
