Two 16GB sticks vs one 32GB stick: Dual-channel wins for performance unless you plan to upgrade later

Two 16GB sticks run in dual-channel mode, doubling memory bandwidth compared to a single 32GB stick in single-channel. That matters for gaming, video editing, and multitasking—expect 5–15% FPS loss or 30–50% slower synthetic benchmarks with one stick. If you need 32GB now and won’t upgrade, go with two sticks. If you plan to add another 32GB later, one stick makes sense.
