Corsair Vengeance 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 Corsair Vengeance 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. Corsair Vengeance 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 Corsair Vengeance 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
Corsair Vengeance DDR5-6400 2x16GB is tracked at 670,05 € — 20,94 € per gigabyte — and Patriot Viper Xtreme 5 DDR5-8000 2x16GB 8200 CL38 at 979,99 €, or 30,62 €. Both are 32GB kits, so the totals compare directly: Corsair Vengeance DDR5-6400 2x16GB is 309,94 € less than Patriot Viper Xtreme 5 DDR5-8000 2x16GB 8200 CL38.
