Performance and where it ranks
Two different questions, side by side. Performance compares what the hardware can do; Value compares what that capability costs at today’s price. A product can rank high on one and low on the other — that gap is the point.

What to check in your build
DDR5
The board must take DDR5 — DDR generations are not interchangeable
288-pin DIMM
Desktop boards take full-size DIMMs; laptops and mini PCs take SO-DIMMs.
2 free slots
A kit is tested as a set; filling fewer slots than modules is not possible.
XMP/EXPO support for 6400 MT/s
6400 MT/s is a profile speed — the board and CPU memory controller have to support it, and it is off until you enable it in BIOS
