G.Skill Trident Z Royal DDR4-4266 2x8GB 4000 CL15 vs Silicon Power XPOWER Turbine DDR4-3200 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 10.00 ns for Silicon Power XPOWER Turbine DDR4-3200 2x8GB — a difference of 2.50 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 Royal DDR4-4266 2x8GB 4000 CL15 runs 4000 MT/s at CL15; Silicon Power XPOWER Turbine DDR4-3200 2x8GB runs 3200 MT/s at CL16.
Transfer rate
G.Skill Trident Z Royal DDR4-4266 2x8GB 4000 CL15 is rated 4000 MT/s against 3200 MT/s for Silicon Power XPOWER Turbine DDR4-3200 2x8GB — 32000 MB/s per module, against 25600 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 Royal DDR4-4266 2x8GB 4000 CL15 is tracked at $109.99 — $6.87 per gigabyte — and Silicon Power XPOWER Turbine DDR4-3200 2x8GB at $99.97, or $6.25. Both are 16GB kits, so the totals compare directly: Silicon Power XPOWER Turbine DDR4-3200 2x8GB is $10.02 less than G.Skill Trident Z Royal DDR4-4266 2x8GB 4000 CL15. $109.99 is the lowest price this site has recorded for G.Skill Trident Z Royal DDR4-4266 2x8GB 4000 CL15. At $99.97, Silicon Power XPOWER Turbine DDR4-3200 2x8GB is running 20% below its own 90-day median.
Kit layout
G.Skill Trident Z Royal DDR4-4266 2x8GB 4000 CL15 ships as 2 × 8GB and Silicon Power XPOWER Turbine DDR4-3200 2x8GB ships as 2 × 8GB — the same number of sticks either way, so both populate a board's slots identically.
Lighting and timings
On the lighting question: G.Skill Trident Z Royal DDR4-4266 2x8GB 4000 CL15 is published with RGB lighting, and Silicon Power XPOWER Turbine DDR4-3200 2x8GB does not have RGB lighting. On the full timing tuple, the numbers that follow CAS: G.Skill Trident Z Royal DDR4-4266 2x8GB 4000 CL15 does not publish one, and Silicon Power XPOWER Turbine DDR4-3200 2x8GB runs 16-18-18-38.
Which to buy
