Corsair Dominator Titanium RGB DDR5-6600 2x16GB 5600 CL36 vs Corsair Vengeance DDR5-5600 2x16GB in detail

True latency

Corsair Dominator Titanium RGB DDR5-6600 2x16GB 5600 CL36 is the lower-latency kit at 12.86 ns, against 14.29 ns for Corsair Vengeance DDR5-5600 2x16GB — a difference of 1.43 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 Dominator Titanium RGB DDR5-6600 2x16GB 5600 CL36 runs 5600 MT/s at CL36; Corsair Vengeance DDR5-5600 2x16GB runs 5600 MT/s at CL40.

Transfer rate

Both kits are rated 5600 MT/s, which is 44800 MB/s per module. Their spec sheets part company on CAS latency rather than on clock, so the true-latency figures above are what separates them.

Price and tracked history

Corsair Dominator Titanium RGB DDR5-6600 2x16GB 5600 CL36 is tracked at £489.00 — £15.28 per gigabyte — and Corsair Vengeance DDR5-5600 2x16GB at £440.00, or £13.75.
