G.Skill Trident Z Neo DDR4-4000 2x16GB CL18 vs Timetec Premium DDR4-2666 UDIMM 2x16GB in detail
True latency
G.Skill Trident Z Neo DDR4-4000 2x16GB CL18 is the lower-latency kit at 9.00 ns against 14.25 ns for Timetec Premium DDR4-2666 UDIMM 2x16GB, 5.25 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. G.Skill Trident Z Neo DDR4-4000 2x16GB CL18 runs 4000 MT/s at CL18; Timetec Premium DDR4-2666 UDIMM 2x16GB runs 2666 MT/s at CL19.
Transfer rate
G.Skill Trident Z Neo DDR4-4000 2x16GB CL18 carries the higher rating, 4000 MT/s to 2666 MT/s for Timetec Premium DDR4-2666 UDIMM 2x16GB — 32000 MB/s per module against 21328 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
G.Skill Trident Z Neo DDR4-4000 2x16GB CL18 is tracked at 283,52 €, or 8,86 € per gigabyte; Timetec Premium DDR4-2666 UDIMM 2x16GB at 190,99 €, or 5,97 €. At the same 32GB, that puts Timetec Premium DDR4-2666 UDIMM 2x16GB 92,53 € less than G.Skill Trident Z Neo DDR4-4000 2x16GB CL18. G.Skill Trident Z Neo DDR4-4000 2x16GB CL18's 283,52 € sits 29% under its own 90-day median.
Kit layout
G.Skill Trident Z Neo DDR4-4000 2x16GB CL18 ships as 2 × 16GB and Timetec Premium DDR4-2666 UDIMM 2x16GB ships as 2 × 16GB — the same number of sticks on both sides, so they populate a board's slots the same way.
Lighting and ECC
On lighting: G.Skill Trident Z Neo DDR4-4000 2x16GB CL18 has RGB lighting, and Timetec Premium DDR4-2666 UDIMM 2x16GB is published with no RGB lighting. On error correction: the catalog does not state whether G.Skill Trident Z Neo DDR4-4000 2x16GB CL18 has it, and Timetec Premium DDR4-2666 UDIMM 2x16GB is published without ECC. ECC is a board and CPU feature as much as a module one, so it is worth having only where the platform can use it.
Which to buy
Neither of these leads outright, so there is no single answer to give. Timetec Premium DDR4-2666 UDIMM 2x16GB costs less at the prices tracked here; G.Skill Trident Z Neo DDR4-4000 2x16GB CL18 has the lower true latency, 9.00 ns against 14.25 ns. Which of those two is worth more is a judgement about the machine and the budget, and this page does not make it for a reader.
Common questions about this pair
- Is G.Skill Trident Z Neo DDR4-4000 2x16GB CL18 faster than Timetec Premium DDR4-2666 UDIMM 2x16GB?
