Crucial Pro DDR5-6400 Overclocking Memory 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 Crucial Pro DDR5-6400 Overclocking Memory 2x16GB, 0.73 ns between them. That is the figure that reconciles the two spec sheets: a CAS number counts cycles, and cycles mean nothing apart from the rate they are counted at. Crucial Pro DDR5-6400 Overclocking Memory 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 carries the higher rating, 8200 MT/s to 6400 MT/s for Crucial Pro DDR5-6400 Overclocking Memory 2x16GB — 65600 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.
Price and tracked history
Crucial Pro DDR5-6400 Overclocking Memory 2x16GB is tracked at $599.99, or $18.75 per gigabyte; Patriot Viper Xtreme 5 DDR5-8000 2x16GB 8200 CL38 at $2,345.00, or $73.28. At the same 32GB, that puts Crucial Pro DDR5-6400 Overclocking Memory 2x16GB $1,745.01 less than Patriot Viper Xtreme 5 DDR5-8000 2x16GB 8200 CL38. Crucial Pro DDR5-6400 Overclocking Memory 2x16GB's $599.99 sits 4% under its own 90-day median.
