Crucial DDR4 SODIMM 2666 1x16GB 2133 CL15 vs G.Skill Ripjaws DDR4-3200 SODIMM 1x16GB in detail
True latency
G.Skill Ripjaws DDR4-3200 SODIMM 1x16GB is the lower-latency kit at 13.75 ns, against 14.06 ns for Crucial DDR4 SODIMM 2666 1x16GB 2133 CL15 — a difference of 0.32 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. Crucial DDR4 SODIMM 2666 1x16GB 2133 CL15 runs 2133 MT/s at CL15; G.Skill Ripjaws DDR4-3200 SODIMM 1x16GB runs 3200 MT/s at CL22.
Transfer rate
G.Skill Ripjaws DDR4-3200 SODIMM 1x16GB is rated 3200 MT/s against 2133 MT/s for Crucial DDR4 SODIMM 2666 1x16GB 2133 CL15 — 25600 MB/s per module, against 17064 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
Crucial DDR4 SODIMM 2666 1x16GB 2133 CL15 is tracked at $95.33 — $5.96 per gigabyte — and G.Skill Ripjaws DDR4-3200 SODIMM 1x16GB at $104.99, or $6.56. Both are 16GB kits, so the totals compare directly: Crucial DDR4 SODIMM 2666 1x16GB 2133 CL15 is $9.66 less than G.Skill Ripjaws DDR4-3200 SODIMM 1x16GB. At $104.99, G.Skill Ripjaws DDR4-3200 SODIMM 1x16GB is running 4% below its own 90-day median.
Kit layout
Crucial DDR4 SODIMM 2666 1x16GB 2133 CL15 ships as 1 × 16GB, G.Skill Ripjaws DDR4-3200 SODIMM 1x16GB ships as 2 × 8GB. 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: Crucial DDR4 SODIMM 2666 1x16GB 2133 CL15 does not have RGB lighting, and G.Skill Ripjaws DDR4-3200 SODIMM 1x16GB does not have RGB lighting. On the full timing tuple, the numbers that follow CAS: Crucial DDR4 SODIMM 2666 1x16GB 2133 CL15 does not publish one, and G.Skill Ripjaws DDR4-3200 SODIMM 1x16GB runs 22-22-22-52.
Which to buy
The two split the axes this page measures, so no one kit is the answer. The lower tracked price belongs to Crucial DDR4 SODIMM 2666 1x16GB 2133 CL15; the lower true latency to G.Skill Ripjaws DDR4-3200 SODIMM 1x16GB, 13.75 ns against 14.06 ns. Weighing money against latency is a decision about the machine, and it stays with the reader.
Common questions about this pair
