DDR4 vs DDR5, Explained
DDR5 doubled the bandwidth and moved power regulation onto the module. Whether that is worth paying for depends entirely on which platform you are building.

NEMIX's DDR5-4800 line is registered ECC memory built for server boards rather than desktop platforms — buffered signaling and error correction aimed at systems that specify RDIMM support, not a drop-in for a consumer motherboard.
This 1×128GB kit is 128GB, rated 4800 MT/s CL40, the single timing this family ships at across every capacity point from 16GB up to a 128GB quad-module kit. Because the whole line holds to one speed and one CL, capacity and module count are what actually distinguish one listing from another here.
All of it is RDIMM DDR5 with ECC, and it will not work in a board that only supports unbuffered consumer memory.
DDR5 doubled the bandwidth and moved power regulation onto the module. Whether that is worth paying for depends entirely on which platform you are building.
Flare X5 is a heatspreader-only DDR5-6000 line built for clearance-constrained builds, and within this 6000 MT/s grade every listing shares that one headline speed — the CL bin and capacity are the only things actually separating listings.
FURY Beast at 6000 spans three CL grades under one name plus a four-module 64GB option its 5600 sibling doesn't offer, which makes matching the exact SKU more important here than with most families.
Crucial Pro trades looks for a compatibility-first, overclocking-headroom pitch, and within this 6400 MT/s grade, CAS latency -- not the shared headline speed -- is the number that actually separates one listing from another.
CAMM2 and SODIMM are physically incompatible laptop memory formats. The difference is not speed at a given rating but how many channels each module carries, how the module attaches, and whether a machine can ever add memory rather than replace it.
16 GB is no longer comfortable, 32 GB is the sensible default, and 64 GB is a workload decision rather than a future-proofing one.
