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.

Highest-rated of the RGB Vengeance kits in this batch, this family carries the same lighting bar as its slower siblings while running at a faster fixed clock. The lighting is standard across every kit here rather than an option on some listings and not others.
Every kit is 7000 MT/s, with CL34 ranging from a tight bin down to a noticeably looser one — at this clock speed, the gap between the best and worst binned kits tends to be wider than at slower Vengeance RGB speed grades. Capacity runs from smaller kits up to 2×16GB kits at the top of the range, and either 32GB configuration needs a board and CPU memory controller rated to handle 7000 MT/s before the profile will actually apply at spec.
This is unbuffered, non-ECC UDIMM, and like the rest of the Vengeance RGB line it needs XMP enabled in BIOS to leave its JEDEC default behind.
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.
