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.

Timetec sells Premium as an unbranded-feeling but specific product: UDIMM DDR5 holding the same 32GB across the range, sold at two different rated speeds rather than two different sizes.
That's the reverse of most families here — check the speed and CL40 on the actual listing, since 4800 MT/s on one SKU and a faster grade on another share the same 2×16GB configuration and the same capacity line.
Neither profile is applied automatically; the board's XMP or EXPO setting has to be turned on in BIOS before either rated speed is reached.

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.
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.
Capacity avoids stutter caused by running out of memory; speed affects how efficiently the CPU feeds data to the GPU. They solve different problems, and buying enough of the first one before spending on the second is the right order.
