Patriot Viper Venom DDR5-6400 2x16GB vs Patriot Viper Venom DDR5-7000 2x16GB in detail
True latency
Patriot Viper Venom DDR5-7000 2x16GB is the lower-latency kit at 9.14 ns, against 10.00 ns for Patriot Viper Venom DDR5-6400 2x16GB — a difference of 0.86 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 Viper Venom DDR5-6400 2x16GB runs 6400 MT/s at CL32; Patriot Viper Venom DDR5-7000 2x16GB runs 7000 MT/s at CL32.
Transfer rate
Patriot Viper Venom DDR5-7000 2x16GB is rated 7000 MT/s against 6400 MT/s for Patriot Viper Venom DDR5-6400 2x16GB — 56000 MB/s per module, against 51200 MB/s. That is peak transfer rate, not access time. Both kits are published at CL32, so the same count of cycles takes less time at the higher clock, and the true latency above is the directly comparable figure.
Price and tracked history
Patriot Viper Venom DDR5-6400 2x16GB is tracked at $619.99 — $19.37 per gigabyte — and Patriot Viper Venom DDR5-7000 2x16GB at $1,051.00, or $32.84.
