Corsair Vengeance RGB RS DDR5-5200 2x16GB vs Kingston ValueRAM DDR5-6400 CUDIMM 1x32GB in detail
True latency
Corsair Vengeance RGB RS DDR5-5200 2x16GB is the lower-latency kit at 15.38 ns, against 16.25 ns for Kingston ValueRAM DDR5-6400 CUDIMM 1x32GB — a difference of 0.86 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 RS DDR5-5200 2x16GB runs 5200 MT/s at CL40; Kingston ValueRAM DDR5-6400 CUDIMM 1x32GB runs 6400 MT/s at CL52.
Transfer rate
Kingston ValueRAM DDR5-6400 CUDIMM 1x32GB is rated 6400 MT/s against 5200 MT/s for Corsair Vengeance RGB RS DDR5-5200 2x16GB — 51200 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 RGB RS DDR5-5200 2x16GB is tracked at $439.99 — $13.75 per gigabyte — and Kingston ValueRAM DDR5-6400 CUDIMM 1x32GB at $1,432.00, or $44.75. Both are 32GB kits, so the totals compare directly: Corsair Vengeance RGB RS DDR5-5200 2x16GB is $992.01 less than Kingston ValueRAM DDR5-6400 CUDIMM 1x32GB.
Kit layout
Corsair Vengeance RGB RS DDR5-5200 2x16GB ships as 2 × 16GB, Kingston ValueRAM DDR5-6400 CUDIMM 1x32GB ships as 1 × 32GB. 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 RGB RS DDR5-5200 2x16GB is published with RGB lighting, and Kingston ValueRAM DDR5-6400 CUDIMM 1x32GB does not have RGB lighting. On the full timing tuple, the numbers that follow CAS: Corsair Vengeance RGB RS DDR5-5200 2x16GB runs 40-40-40-77, and Kingston ValueRAM DDR5-6400 CUDIMM 1x32GB does not publish one.
Which to buy
Corsair Vengeance RGB RS DDR5-5200 2x16GB leads Kingston ValueRAM DDR5-6400 CUDIMM 1x32GB on both of the axes this page measures: the lower true latency, 15.38 ns against 16.25 ns, and the lower price of the two at what this site has tracked.
