G.Skill Trident Z Royal DDR4-4266 2x8GB 4000 CL15 vs Timetec Premium DDR4-3200 UDIMM 2x8GB in detail
True latency
G.Skill Trident Z Royal DDR4-4266 2x8GB 4000 CL15 is the lower-latency kit at 7.50 ns against 13.75 ns for Timetec Premium DDR4-3200 UDIMM 2x8GB, 6.25 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 Royal DDR4-4266 2x8GB 4000 CL15 runs 4000 MT/s at CL15; Timetec Premium DDR4-3200 UDIMM 2x8GB runs 3200 MT/s at CL22.
Transfer rate
G.Skill Trident Z Royal DDR4-4266 2x8GB 4000 CL15 carries the higher rating, 4000 MT/s to 3200 MT/s for Timetec Premium DDR4-3200 UDIMM 2x8GB — 32000 MB/s per module against 25600 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 Royal DDR4-4266 2x8GB 4000 CL15 is tracked at $109.99, or $6.87 per gigabyte; Timetec Premium DDR4-3200 UDIMM 2x8GB at $101.99, or $6.37. At the same 16GB, that puts Timetec Premium DDR4-3200 UDIMM 2x8GB $8.00 less than G.Skill Trident Z Royal DDR4-4266 2x8GB 4000 CL15. $109.99 is the lowest this site has ever recorded for G.Skill Trident Z Royal DDR4-4266 2x8GB 4000 CL15.
Kit layout
G.Skill Trident Z Royal DDR4-4266 2x8GB 4000 CL15 ships as 2 × 8GB and Timetec Premium DDR4-3200 UDIMM 2x8GB ships as 2 × 8GB — 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 2x8GB 4000 CL15 has RGB lighting, and Timetec Premium DDR4-3200 UDIMM 2x8GB is published with no RGB lighting. On error correction: the catalog does not state whether G.Skill Trident Z Royal DDR4-4266 2x8GB 4000 CL15 has it, and Timetec Premium DDR4-3200 UDIMM 2x8GB 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 DDR4-3200 UDIMM 2x8GB costs less at the prices tracked here; G.Skill Trident Z Royal DDR4-4266 2x8GB 4000 CL15 has the lower true latency, 7.50 ns against 13.75 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.
