G.Skill Trident Z Royal DDR4-4266 2x16GB vs Timetec Premium DDR4-2666 UDIMM 2x16GB in detail
True latency
G.Skill Trident Z Royal DDR4-4266 2x16GB is the lower-latency kit at 7.97 ns against 14.25 ns for Timetec Premium DDR4-2666 UDIMM 2x16GB, 6.28 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 Royal DDR4-4266 2x16GB runs 4266 MT/s at CL17; Timetec Premium DDR4-2666 UDIMM 2x16GB runs 2666 MT/s at CL19.
Transfer rate
G.Skill Trident Z Royal DDR4-4266 2x16GB carries the higher rating, 4266 MT/s to 2666 MT/s for Timetec Premium DDR4-2666 UDIMM 2x16GB — 34128 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 Royal DDR4-4266 2x16GB 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 Royal DDR4-4266 2x16GB 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 Royal DDR4-4266 2x16GB 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
The site holds no current price for at least one of these, so no buying answer follows: which is worth more turns on what each costs, and that figure is the one missing. On the specifications alone, G.Skill Trident Z Royal DDR4-4266 2x16GB is the quicker at 7.97 ns of true latency.
