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.
Kit layout
Patriot Viper Venom DDR5-6400 2x16GB ships as 2 × 16GB and Patriot Viper Venom DDR5-7000 2x16GB ships as 2 × 16GB — the same number of sticks either way, so both populate a board's slots identically.
Lighting and timings
On the lighting question: Patriot Viper Venom DDR5-6400 2x16GB does not have RGB lighting, and Patriot Viper Venom DDR5-7000 2x16GB does not have RGB lighting. On the full timing tuple, the numbers that follow CAS: Patriot Viper Venom DDR5-6400 2x16GB runs 32-40-40-84, and Patriot Viper Venom DDR5-7000 2x16GB does not publish one.
Which to buy
The site holds no current price for at least one of these, so no buying answer follows: which is worth more turns on what each costs, and that figure is the one missing. On the specifications alone, Patriot Viper Venom DDR5-7000 2x16GB is the quicker at 9.14 ns of true latency.
