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.

This corner of Kingston's FURY Beast DDR5 range covers a single-stick option and a matched pair rather than a spread of speed grades — a plain heatspreader over standard modules, positioned as the everyday option beneath Kingston's higher-end kits.
This kit comes as 2×16GB, giving 32GB total at 6800 MT/s CL34. A single 32GB module and a two-module kit at the same 6800 MT/s behave differently in a dual-channel board — one module runs single-channel regardless of how fast it's rated, so check whether a build actually needs the paired kit rather than one large stick.
This is UDIMM DDR5 for standard desktop boards. As with any DDR5 kit, 6800 MT/s is only reached once the correct XMP or EXPO profile is selected in BIOS.

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.
