Corsair Vengeance LPX DDR4-3200 2x16GB 2666 CL16 vs Crucial Ballistix DDR4-3200 4x8GB 2400 CL16 in detail
True latency
Corsair Vengeance LPX DDR4-3200 2x16GB 2666 CL16 is the lower-latency kit at 12.00 ns against 13.33 ns for Crucial Ballistix DDR4-3200 4x8GB 2400 CL16, 1.33 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 LPX DDR4-3200 2x16GB 2666 CL16 runs 2666 MT/s at CL16; Crucial Ballistix DDR4-3200 4x8GB 2400 CL16 runs 2400 MT/s at CL16.
Transfer rate
Corsair Vengeance LPX DDR4-3200 2x16GB 2666 CL16 carries the higher rating, 2666 MT/s to 2400 MT/s for Crucial Ballistix DDR4-3200 4x8GB 2400 CL16 — 21328 MB/s per module against 19200 MB/s. That is peak transfer rate, not access time. Both kits are published at CL16, so an identical count of cycles simply completes sooner at the higher clock, and the true latency above is the figure that compares directly.
Price and tracked history
Corsair Vengeance LPX DDR4-3200 2x16GB 2666 CL16 is tracked at $435.99, or $13.62 per gigabyte; Crucial Ballistix DDR4-3200 4x8GB 2400 CL16 at $289.00, or $9.03. At the same 32GB, that puts Crucial Ballistix DDR4-3200 4x8GB 2400 CL16 $146.99 less than Corsair Vengeance LPX DDR4-3200 2x16GB 2666 CL16. $289.00 is the lowest this site has ever recorded for Crucial Ballistix DDR4-3200 4x8GB 2400 CL16.
