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.

Lexar THOR Z RGB DDR5-6000 2x16GB 6800 CL34 price history in FR: current low €649.99, 12-month low €154.99, 12-month median €599.99.
Above typical — consider waiting — current price is 8% above the 3-month median.
THOR Z RGB is Lexar's enthusiast DDR5 desktop kit, sold as a matched pair at one fixed capacity across the whole family — the variation here is entirely in the speed bin, which runs unusually high for a UDIMM kit.
2×16GB at 6800 MT/s CL34 is what to read closely: two THOR Z RGB kits can carry the same 32GB while sitting at quite different speed grades, and the faster bins in this family sit well above what most desktop boards will run without deliberately selecting a fast EXPO or XMP profile in firmware — some boards may not support the top grades at all.
It's DDR5 UDIMM with RGB lighting built into every kit in the line. Check your board's supported speed ceiling before ordering toward the faster end of the range.
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.
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.
