32GB DDR4 vs 16GB DDR5: Capacity wins for most people

Stick with 32GB DDR4. Capacity matters more than speed in almost every real-world scenario — 16GB is already tight for gaming, video editing, or running a dozen browser tabs. Unless you’re building a new system that only supports DDR5 or need bandwidth for specific professional workloads, the extra 16GB will serve you better. More memory now beats faster memory later.
