Crucial DDR4 SODIMM 2666 2x16GB 2133 CL15 vs Samsung DDR4-3200 SODIMM 2x16GB in detail
True latency
Samsung DDR4-3200 SODIMM 2x16GB is the lower-latency kit at 13.75 ns against 14.06 ns for Crucial DDR4 SODIMM 2666 2x16GB 2133 CL15, 0.32 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. Crucial DDR4 SODIMM 2666 2x16GB 2133 CL15 runs 2133 MT/s at CL15; Samsung DDR4-3200 SODIMM 2x16GB runs 3200 MT/s at CL22.
Transfer rate
Samsung DDR4-3200 SODIMM 2x16GB carries the higher rating, 3200 MT/s to 2133 MT/s for Crucial DDR4 SODIMM 2666 2x16GB 2133 CL15 — 25600 MB/s per module against 17064 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.
Kit layout
Crucial DDR4 SODIMM 2666 2x16GB 2133 CL15 ships as 1 × 32GB, Samsung DDR4-3200 SODIMM 2x16GB ships as 2 × 16GB. 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 adding later. Which suits comes down to the board and to whether more memory is planned.
Lighting
On lighting: Crucial DDR4 SODIMM 2666 2x16GB 2133 CL15 is published with no RGB lighting, and Samsung DDR4-3200 SODIMM 2x16GB is published with no RGB lighting.
Which to buy
Without a tracked price for both, this page cannot say which to buy — the answer depends on cost, and cost is what is absent. What the specifications do say is that Samsung DDR4-3200 SODIMM 2x16GB has the lower true latency, 13.75 ns.
Common questions about this pair
- Is Crucial DDR4 SODIMM 2666 2x16GB 2133 CL15 faster than Samsung DDR4-3200 SODIMM 2x16GB?
- Yes, on true latency: 13.75 ns for Samsung DDR4-3200 SODIMM 2x16GB against 14.06 ns for Crucial DDR4 SODIMM 2666 2x16GB 2133 CL15. Crucial DDR4 SODIMM 2666 2x16GB 2133 CL15 runs 2133 MT/s at CL15 and Samsung DDR4-3200 SODIMM 2x16GB runs 3200 MT/s at CL22, and the CAS numbers alone will not settle it — they count clock cycles, not time.
