Corsair Vengeance DDR5-6800 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 11.77 ns for Corsair Vengeance DDR5-6800 2x16GB, 1.76 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. Corsair Vengeance DDR5-6800 2x16GB runs 6800 MT/s at CL40; Patriot Viper Venom DDR5-6400 2x16GB runs 6400 MT/s at CL32.
Transfer rate
Corsair Vengeance DDR5-6800 2x16GB carries the higher rating, 6800 MT/s to 6400 MT/s for Patriot Viper Venom DDR5-6400 2x16GB — 54400 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.
Kit layout
Corsair Vengeance DDR5-6800 2x16GB ships as 2 × 16GB and Patriot Viper Venom DDR5-6400 2x16GB ships as 2 × 16GB — the same number of sticks on both sides, so they populate a board's slots the same way.
Lighting and timings
On lighting: Corsair Vengeance DDR5-6800 2x16GB is published with no RGB lighting, and Patriot Viper Venom DDR5-6400 2x16GB is published with no RGB lighting. On the full timing tuple — the numbers after CAS — Corsair Vengeance DDR5-6800 2x16GB publishes none, and Patriot Viper Venom DDR5-6400 2x16GB is 32-40-40-84.
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 DDR5-6400 2x16GB is the quicker at 10.00 ns of true latency.
