Lexar ARES RGB 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 Lexar ARES RGB 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. Lexar ARES RGB 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 Lexar ARES RGB 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.

Price and tracked history

Lexar ARES RGB DDR5-6400 2x16GB is tracked at 678,99 € — 21,22 € per gigabyte — and Patriot Viper Xtreme 5 DDR5-8000 2x16GB 8200 CL38 at 1049,99 €, or 32,81 €.
