Kingston FURY Beast DDR5-5600 2x16GB vs PHS-memory DDR5-6400 CUDIMM 2x16GB in detail
True latency
Kingston FURY Beast DDR5-5600 2x16GB is the lower-latency kit at 14.29 ns against 16.25 ns for PHS-memory DDR5-6400 CUDIMM 2x16GB, 1.96 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. Kingston FURY Beast DDR5-5600 2x16GB runs 5600 MT/s at CL40; PHS-memory DDR5-6400 CUDIMM 2x16GB runs 6400 MT/s at CL52.
Transfer rate
PHS-memory DDR5-6400 CUDIMM 2x16GB carries the higher rating, 6400 MT/s to 5600 MT/s for Kingston FURY Beast DDR5-5600 2x16GB — 51200 MB/s per module against 44800 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
Kingston FURY Beast DDR5-5600 2x16GB ships as 2 × 16GB and PHS-memory DDR5-6400 CUDIMM 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 timings
On lighting: Kingston FURY Beast DDR5-5600 2x16GB is published with no RGB lighting, and PHS-memory DDR5-6400 CUDIMM 2x16GB is published with no RGB lighting. On the full timing tuple — the numbers after CAS — Kingston FURY Beast DDR5-5600 2x16GB is 40-40-40, and PHS-memory DDR5-6400 CUDIMM 2x16GB publishes none.
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, Kingston FURY Beast DDR5-5600 2x16GB has the lower true latency at 14.29 ns.
