Larger capacity is usually slower though. The fastest ram is typically 16 or 32 capacity.

The OP is talking about a specific niche of boosting single thread performance. It’s common with gaming pcs since most games are single thread bottlenecked. 5% difference may seem small, but people are spending hundreds or thousands for less gains… so buying the fastest ram can make sense there.
