Corsair Vengeance RGB 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 RGB 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 RGB 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 RGB 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.
Kit layout
Corsair Vengeance RGB 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.
Lighting and timings
On the lighting question: Corsair Vengeance RGB DDR5-6800 2x16GB is published with RGB lighting, and Crucial Pro DDR5-6400 Overclocking Memory 2x16GB does not have RGB lighting. On the full timing tuple, the numbers that follow CAS: Corsair Vengeance RGB DDR5-6800 2x16GB does not publish one, and Crucial Pro DDR5-6400 Overclocking Memory 2x16GB runs 32-40-40-103.
Which to buy
At least one of these kits has no tracked price right now, so this page has no buying answer to give: which is worth more depends on what each costs, and that is exactly what is missing. On specifications alone, Crucial Pro DDR5-6400 Overclocking Memory 2x16GB has the lower true latency at 10.00 ns.
Common questions about this pair
- Is Corsair Vengeance RGB DDR5-6800 2x16GB faster than Crucial Pro DDR5-6400 Overclocking Memory 2x16GB?
- Crucial Pro DDR5-6400 Overclocking Memory 2x16GB is, on true latency: 10.00 ns against 11.77 ns. Corsair Vengeance RGB DDR5-6800 2x16GB runs 6800 MT/s at CL40 and Crucial Pro DDR5-6400 Overclocking Memory 2x16GB runs 6400 MT/s at CL32; the CAS numbers alone do not settle it, because they count clock cycles rather than time.
