Corsair Vengeance RGB RS DDR5-5200 2x16GB vs Patriot Viper Venom DDR5-6400 2x16GB in detail
True latency
Patriot Viper Venom DDR5-6400 2x16GB is the lower-latency kit at 10.00 ns, against 15.38 ns for Corsair Vengeance RGB RS DDR5-5200 2x16GB — a difference of 5.38 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 RGB RS DDR5-5200 2x16GB runs 5200 MT/s at CL40; Patriot Viper Venom DDR5-6400 2x16GB runs 6400 MT/s at CL32.
Transfer rate
Patriot Viper Venom DDR5-6400 2x16GB is rated 6400 MT/s against 5200 MT/s for Corsair Vengeance RGB RS DDR5-5200 2x16GB — 51200 MB/s per module, against 41600 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 RGB RS DDR5-5200 2x16GB is tracked at $639.99 — $20.00 per gigabyte — and Patriot Viper Venom DDR5-6400 2x16GB at $619.99, or $19.37. Both are 32GB kits, so the totals compare directly: Patriot Viper Venom DDR5-6400 2x16GB is $20.00 less than Corsair Vengeance RGB RS DDR5-5200 2x16GB. At $619.99, Patriot Viper Venom DDR5-6400 2x16GB is running 42% below its own 90-day median.
Kit layout
Corsair Vengeance RGB RS DDR5-5200 2x16GB ships as 2 × 16GB and Patriot Viper Venom DDR5-6400 2x16GB ships as 2 × 16GB — the same number of sticks either way, so both populate a board's slots identically.
