Corsair Vengeance DDR5-6800 2x16GB vs Crucial Pro DDR5-6400 Overclocking Memory 2x16GB in detail
True latency
Crucial Pro DDR5-6400 Overclocking Memory 2x16GB is the lower-latency kit at 10.00 ns, against 11.77 ns for Corsair Vengeance DDR5-6800 2x16GB — a difference of 1.76 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 DDR5-6800 2x16GB runs 6800 MT/s at CL40; Crucial Pro DDR5-6400 Overclocking Memory 2x16GB runs 6400 MT/s at CL32.
Transfer rate
Corsair Vengeance DDR5-6800 2x16GB is rated 6800 MT/s against 6400 MT/s for Crucial Pro DDR5-6400 Overclocking Memory 2x16GB — 54400 MB/s per module, against 51200 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 DDR5-6800 2x16GB is tracked at $777.99 — $24.31 per gigabyte — and Crucial Pro DDR5-6400 Overclocking Memory 2x16GB at $599.99, or $18.75. Both are 32GB kits, so the totals compare directly: Crucial Pro DDR5-6400 Overclocking Memory 2x16GB is $178.00 less than Corsair Vengeance DDR5-6800 2x16GB. At $599.99, Crucial Pro DDR5-6400 Overclocking Memory 2x16GB is running 4% below its own 90-day median.
Kit layout
Corsair Vengeance DDR5-6800 2x16GB ships as 2 × 16GB and Crucial Pro DDR5-6400 Overclocking Memory 2x16GB ships as 2 × 16GB — the same number of sticks either way, so both populate a board's slots identically.
