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.
Price and tracked history
Kingston FURY Beast DDR5-5600 2x16GB is tracked at 243,43 €, or 7,61 € per gigabyte; PHS-memory DDR5-6400 CUDIMM 2x16GB at 903,76 €, or 28,24 €. At the same 32GB, that puts Kingston FURY Beast DDR5-5600 2x16GB 660,33 € less than PHS-memory DDR5-6400 CUDIMM 2x16GB. Kingston FURY Beast DDR5-5600 2x16GB's 243,43 € sits 55% under its own 90-day median. PHS-memory DDR5-6400 CUDIMM 2x16GB's 903,76 € sits 12% under its own 90-day median.
