G.Skill Trident Z Neo DDR4-4000 2x16GB vs Timetec Premium DDR4-2666 UDIMM 2x16GB in detail
True latency
G.Skill Trident Z Neo DDR4-4000 2x16GB is the lower-latency kit at 8.00 ns, against 14.25 ns for Timetec Premium DDR4-2666 UDIMM 2x16GB — a difference of 6.25 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. G.Skill Trident Z Neo DDR4-4000 2x16GB runs 4000 MT/s at CL16; Timetec Premium DDR4-2666 UDIMM 2x16GB runs 2666 MT/s at CL19.
Transfer rate
G.Skill Trident Z Neo DDR4-4000 2x16GB is rated 4000 MT/s against 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: 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
G.Skill Trident Z Neo DDR4-4000 2x16GB is tracked at $669.00 — $20.91 per gigabyte — and Timetec Premium DDR4-2666 UDIMM 2x16GB at $189.99, or $5.94. Both are 32GB kits, so the totals compare directly: Timetec Premium DDR4-2666 UDIMM 2x16GB is $479.01 less than G.Skill Trident Z Neo DDR4-4000 2x16GB. $669.00 is the lowest price this site has recorded for G.Skill Trident Z Neo DDR4-4000 2x16GB.
Kit layout
G.Skill Trident Z Neo DDR4-4000 2x16GB ships as 2 × 16GB and Timetec Premium DDR4-2666 UDIMM 2x16GB ships as 2 × 16GB — the same number of sticks either way, so both populate a board's slots identically.
Lighting and ECC
On the lighting question: G.Skill Trident Z Neo DDR4-4000 2x16GB is published with RGB lighting, and Timetec Premium DDR4-2666 UDIMM 2x16GB does not have RGB lighting. On error correction: the catalog does not state whether G.Skill Trident Z Neo DDR4-4000 2x16GB supports it, and Timetec Premium DDR4-2666 UDIMM 2x16GB is published with no ECC. Whether ECC is worth having depends on the platform as much as the modules — the board and the CPU have to support it too.
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 has the lower true latency, 8.00 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.
