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.
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
At least one of these kits has no tracked price right now, so this page has no buying answer to give: which is worth more depends on what each costs, and that is exactly what is missing. On specifications alone, G.Skill Trident Z Neo DDR4-4000 2x16GB CL18 has the lower true latency at 9.00 ns.
Common questions about this pair
- Is G.Skill Trident Z Neo DDR4-4000 2x16GB CL18 faster than Timetec Premium DDR4-2666 UDIMM 2x16GB?
- Yes, on true latency: 9.00 ns for G.Skill Trident Z Neo DDR4-4000 2x16GB CL18 against 14.25 ns for Timetec Premium DDR4-2666 UDIMM 2x16GB. G.Skill Trident Z Neo DDR4-4000 2x16GB CL18 runs 4000 MT/s at CL18 and Timetec Premium DDR4-2666 UDIMM 2x16GB runs 2666 MT/s at CL19, and the CAS numbers alone will not settle it — they count clock cycles, not time.
