G.Skill Flare X5 DDR5-5600 2x32GB vs G.Skill Flare X5 DDR5-6000 2x32GB CL28 in detail
True latency
G.Skill Flare X5 DDR5-6000 2x32GB CL28 is the lower-latency kit at 9.33 ns, against 12.86 ns for G.Skill Flare X5 DDR5-5600 2x32GB — a difference of 3.52 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. G.Skill Flare X5 DDR5-5600 2x32GB runs 5600 MT/s at CL36; G.Skill Flare X5 DDR5-6000 2x32GB CL28 runs 6000 MT/s at CL28.
Transfer rate
G.Skill Flare X5 DDR5-6000 2x32GB CL28 is rated 6000 MT/s against 5600 MT/s for G.Skill Flare X5 DDR5-5600 2x32GB — 48000 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
G.Skill Flare X5 DDR5-5600 2x32GB is tracked at $940.00 — $14.69 per gigabyte — and G.Skill Flare X5 DDR5-6000 2x32GB CL28 at $1,940.00, or $30.31. Both are 64GB kits, so the totals compare directly: G.Skill Flare X5 DDR5-5600 2x32GB is $1,000.00 less than G.Skill Flare X5 DDR5-6000 2x32GB CL28. At $940.00, G.Skill Flare X5 DDR5-5600 2x32GB is running 1% below its own 90-day median. $1,940.00 is the lowest price this site has recorded for G.Skill Flare X5 DDR5-6000 2x32GB CL28.
Kit layout
G.Skill Flare X5 DDR5-5600 2x32GB ships as 2 × 32GB and G.Skill Flare X5 DDR5-6000 2x32GB CL28 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: G.Skill Flare X5 DDR5-5600 2x32GB does not have RGB lighting, and G.Skill Flare X5 DDR5-6000 2x32GB CL28 does not have RGB lighting. On the full timing tuple, the numbers that follow CAS: G.Skill Flare X5 DDR5-5600 2x32GB does not publish one, and G.Skill Flare X5 DDR5-6000 2x32GB CL28 runs 30-38-38-96. On error correction: the catalog does not state whether G.Skill Flare X5 DDR5-5600 2x32GB supports it, and G.Skill Flare X5 DDR5-6000 2x32GB CL28 is published with no ECC. 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
Neither of these leads outright, so there is no single answer to give. G.Skill Flare X5 DDR5-5600 2x32GB costs less at the prices tracked here; G.Skill Flare X5 DDR5-6000 2x32GB CL28 has the lower true latency, 9.33 ns against 12.86 ns. Which of those two is worth more is a judgement about the machine and the budget, and this page does not make it for a reader.
