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.

Trident Z5 RGB sits at the fast end of G.Skill's DDR5 range, with the brand's usual RGB light bar and a rating high enough that it depends heavily on the memory controller and motherboard actually supporting it at that speed.
Every kit here shares the 8000 MT/s rating, so CAS latency is what actually separates listings — a CL38 bin is a tighter or looser part of the family, and this one is 2×16GB at 32GB. At a speed this high, whether a given board and CPU combination can hold that rating stably matters more than it does further down the DDR5 range.
It's DDR5 UDIMM, non-ECC, for desktop boards, and reaches 8000 MT/s only with its EXPO or XMP profile enabled and, in practice, a platform validated for that rating.

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.
