16GB vs 32GB RAM for DaVinci Resolve: 32GB wins for 4K and compressed codecs

32GB gives noticeably smoother scrubbing and previews in DaVinci Resolve compared to 16GB, but only if you’re working with 4K footage or heavily compressed codecs like H.264/H.265. For 1080p ProRes or DNxHR, 16GB is usually fine. DaVinci caches frames in memory, and 16GB causes swapping or dropped frames, while 32GB keeps timeline previews fluid. A fast GPU and SSD matter more for real-time playback, so 32GB won’t fix choppy previews on slow hardware alone.
