Corsair Vengeance DDR5-5200 2x48GB CL38 vs Corsair Vengeance RGB DDR5-5600 4x24GB CL40 in detail
True latency
Corsair Vengeance RGB DDR5-5600 4x24GB CL40 is the lower-latency kit at 14.29 ns, against 14.62 ns for Corsair Vengeance DDR5-5200 2x48GB CL38 — a difference of 0.33 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 DDR5-5200 2x48GB CL38 runs 5200 MT/s at CL38; Corsair Vengeance RGB DDR5-5600 4x24GB CL40 runs 5600 MT/s at CL40.
Transfer rate
Corsair Vengeance RGB DDR5-5600 4x24GB CL40 is rated 5600 MT/s against 5200 MT/s for Corsair Vengeance DDR5-5200 2x48GB CL38 — 44800 MB/s per module, against 41600 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 DDR5-5200 2x48GB CL38 is tracked at $2,483.90 — $25.87 per gigabyte — and Corsair Vengeance RGB DDR5-5600 4x24GB CL40 at $1,999.99, or $20.83. Both are 96GB kits, so the totals compare directly: Corsair Vengeance RGB DDR5-5600 4x24GB CL40 is $483.91 less than Corsair Vengeance DDR5-5200 2x48GB CL38.
Kit layout
Corsair Vengeance DDR5-5200 2x48GB CL38 ships as 2 × 48GB, Corsair Vengeance RGB DDR5-5600 4x24GB CL40 ships as 4 × 24GB. That is a real difference and not a ranking: more sticks fill more channels on a board that has them, while fewer sticks leave slots free for a later addition. Which suits depends on the board and on whether more memory is planned.
Lighting and timings
On the lighting question: Corsair Vengeance DDR5-5200 2x48GB CL38 does not have RGB lighting, and Corsair Vengeance RGB DDR5-5600 4x24GB CL40 is published with RGB lighting. On the full timing tuple, the numbers that follow CAS: Corsair Vengeance DDR5-5200 2x48GB CL38 does not publish one, and Corsair Vengeance RGB DDR5-5600 4x24GB CL40 runs 40-40-40-77.
Which to buy
Corsair Vengeance RGB DDR5-5600 4x24GB CL40 gives up nothing to Corsair Vengeance DDR5-5200 2x48GB CL38 on what is measured here: quicker on true latency at 14.29 ns against 14.62 ns, and the cheaper of the two at the prices this site has tracked.
