G.Skill Ripjaws M5 RGB DDR5-5200 2x48GB vs PHS-memory DDR5-5600 ECC UDIMM 2x48GB in detail
True latency
G.Skill Ripjaws M5 RGB DDR5-5200 2x48GB is the lower-latency kit at 15.38 ns against 16.43 ns for PHS-memory DDR5-5600 ECC UDIMM 2x48GB, 1.04 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 Ripjaws M5 RGB DDR5-5200 2x48GB runs 5200 MT/s at CL40; PHS-memory DDR5-5600 ECC UDIMM 2x48GB runs 5600 MT/s at CL46.
Transfer rate
PHS-memory DDR5-5600 ECC UDIMM 2x48GB carries the higher rating, 5600 MT/s to 5200 MT/s for G.Skill Ripjaws M5 RGB DDR5-5200 2x48GB — 44800 MB/s per module against 41600 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 Ripjaws M5 RGB DDR5-5200 2x48GB ships as 2 × 48GB and PHS-memory DDR5-5600 ECC UDIMM 2x48GB ships as 2 × 48GB — 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 Ripjaws M5 RGB DDR5-5200 2x48GB has RGB lighting, and PHS-memory DDR5-5600 ECC UDIMM 2x48GB is published with no RGB lighting. On error correction: the catalog does not state whether G.Skill Ripjaws M5 RGB DDR5-5200 2x48GB has it, and PHS-memory DDR5-5600 ECC UDIMM 2x48GB supports 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 Ripjaws M5 RGB DDR5-5200 2x48GB is the quicker at 15.38 ns of true latency.
Common questions about this pair
- Is G.Skill Ripjaws M5 RGB DDR5-5200 2x48GB faster than PHS-memory DDR5-5600 ECC UDIMM 2x48GB?
- Yes, on true latency: 15.38 ns for G.Skill Ripjaws M5 RGB DDR5-5200 2x48GB against 16.43 ns for PHS-memory DDR5-5600 ECC UDIMM 2x48GB. G.Skill Ripjaws M5 RGB DDR5-5200 2x48GB runs 5200 MT/s at CL40 and PHS-memory DDR5-5600 ECC UDIMM 2x48GB runs 5600 MT/s at CL46, and the CAS numbers alone will not settle it — they count clock cycles, not time.
