Corsair Dominator Titanium RGB DDR5-6600 2x32GB vs G.Skill Flare X5 DDR5-5600 2x32GB in detail
True latency
Corsair Dominator Titanium RGB DDR5-6600 2x32GB is the lower-latency kit at 9.70 ns, against 12.86 ns for G.Skill Flare X5 DDR5-5600 2x32GB — a difference of 3.16 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 2x32GB runs 6600 MT/s at CL32; G.Skill Flare X5 DDR5-5600 2x32GB runs 5600 MT/s at CL36.
Transfer rate
Corsair Dominator Titanium RGB DDR5-6600 2x32GB is rated 6600 MT/s against 5600 MT/s for G.Skill Flare X5 DDR5-5600 2x32GB — 52800 MB/s per module, against 44800 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 Dominator Titanium RGB DDR5-6600 2x32GB is tracked at $1,789.99 — $27.97 per gigabyte — and G.Skill Flare X5 DDR5-5600 2x32GB at $1,379.99, or $21.56. Both are 64GB kits, so the totals compare directly: G.Skill Flare X5 DDR5-5600 2x32GB is $410.00 less than Corsair Dominator Titanium RGB DDR5-6600 2x32GB. $1,789.99 is the lowest price this site has recorded for Corsair Dominator Titanium RGB DDR5-6600 2x32GB. $1,379.99 is the lowest price this site has recorded for G.Skill Flare X5 DDR5-5600 2x32GB.
Kit layout
Corsair Dominator Titanium RGB DDR5-6600 2x32GB ships as 2 × 32GB and G.Skill Flare X5 DDR5-5600 2x32GB ships as 2 × 32GB — the same number of sticks either way, so both populate a board's slots identically.
Lighting, timings and ECC
On the lighting question: Corsair Dominator Titanium RGB DDR5-6600 2x32GB is published with RGB lighting, and G.Skill Flare X5 DDR5-5600 2x32GB does not have RGB lighting. On the full timing tuple, the numbers that follow CAS: Corsair Dominator Titanium RGB DDR5-6600 2x32GB runs 32-39-39-76, and G.Skill Flare X5 DDR5-5600 2x32GB does not publish one. On error correction: Corsair Dominator Titanium RGB DDR5-6600 2x32GB is published with no ECC, and the catalog does not state whether G.Skill Flare X5 DDR5-5600 2x32GB supports it. Whether ECC is worth having depends on the platform as much as the modules — the board and the CPU have to support it too.
Which to buy
There is no single answer here, because each kit leads on one axis. G.Skill Flare X5 DDR5-5600 2x32GB is the cheaper at the prices tracked here, and Corsair Dominator Titanium RGB DDR5-6600 2x32GB the quicker on true latency at 9.70 ns against 12.86 ns. Which matters more depends on the build and the budget, and that is not a call this page can make.
