Patriot Signature Line DDR5-5600 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 16.43 ns for Patriot Signature Line DDR5-5600 2x16GB — a difference of 7.16 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. Patriot Signature Line DDR5-5600 2x16GB runs 5600 MT/s at CL46; 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 5600 MT/s for Patriot Signature Line DDR5-5600 2x16GB — 65600 MB/s per module, against 44800 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
Patriot Signature Line DDR5-5600 2x16GB is tracked at £325.68 — £10.18 per gigabyte — and Patriot Viper Xtreme 5 DDR5-8000 2x16GB 8200 CL38 at £399.99, or £12.50. Both are 32GB kits, so the totals compare directly: Patriot Signature Line DDR5-5600 2x16GB is £74.31 less than Patriot Viper Xtreme 5 DDR5-8000 2x16GB 8200 CL38. At £325.68, Patriot Signature Line DDR5-5600 2x16GB is running 48% below its own 90-day median.
