The desktop side of Corsair's Vengeance DDR5 range sells each speed grade at one fixed clock and lets capacity vary instead, from a modest pair of small sticks up to sets built for boards meant to run a full complement of memory.
2×8GB of DDR5 UDIMM gives 16GB in this listing, rated at this grade's 5600 MT/s CL40 — the practical question is less about speed, since every kit in the grade shares it, and more about whether your board and use case call for two populated slots or four. That rated speed still needs EXPO or XMP selected in firmware to be reached, on standard desktop boards built for unbuffered, non-ECC memory like the rest of Corsair's mainstream Vengeance line.
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.
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.
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.
A 2x16GB kit sits at the highest-volume point on the memory market, and volume is what actually sets price per gigabyte — not capacity, and not how new a kit's specification is.
