Corsair Vengeance DDR5-4800 2x32GB vs Corsair Vengeance RGB DDR5-6400 2x32GB in detail
True latency
Corsair Vengeance RGB DDR5-6400 2x32GB is the lower-latency kit at 10.00 ns against 16.67 ns for Corsair Vengeance DDR5-4800 2x32GB, 6.67 ns between them. That is the figure that reconciles the two spec sheets: a CAS number counts cycles, and cycles mean nothing apart from the rate they are counted at. Corsair Vengeance DDR5-4800 2x32GB runs 4800 MT/s at CL40; Corsair Vengeance RGB DDR5-6400 2x32GB runs 6400 MT/s at CL32.
Transfer rate
Corsair Vengeance RGB DDR5-6400 2x32GB carries the higher rating, 6400 MT/s to 4800 MT/s for Corsair Vengeance DDR5-4800 2x32GB — 51200 MB/s per module against 38400 MB/s. That is peak transfer rate, not access time: a higher clock is reached by counting more cycles for each access, which is why the CAS numbers differ too and why the true latency above is the directly comparable figure.
Price and tracked history
Corsair Vengeance DDR5-4800 2x32GB is tracked at 1 124,42 €, or 17,57 € per gigabyte; Corsair Vengeance RGB DDR5-6400 2x32GB at 1 115,83 €, or 17,43 €. At the same 64GB, that puts Corsair Vengeance RGB DDR5-6400 2x32GB 8,59 € less than Corsair Vengeance DDR5-4800 2x32GB. Corsair Vengeance RGB DDR5-6400 2x32GB's 1 115,83 € sits 18% under its own 90-day median.
