32GB is the floor for 4K Resolve

You will regret trying to edit 4K in DaVinci Resolve with 16GB.

It’s not that it won’t run — it will. You’ll be able to cut a timeline and maybe even do basic color grading. But the second you add a few nodes, throw in Fusion effects, or work with long timelines, the system will start swapping to disk. That’s where the pain lives. Choppy playback, stuttering scrubbing, and that spinning beach ball (or frozen Windows cursor) will become your constant companions.

Resolve is a memory hog. It uses your RAM for everything: decoding video frames, caching, running Fusion comps, even handling audio. On a 4K timeline, 16GB gets eaten before you finish your first coffee. 32GB gives you breathing room. You can actually preview your timeline without dropping frames. If you work with compressed codecs like H.264 or H.265, the RAM usage jumps even higher because the CPU/GPU needs to decompress those frames on the fly.

If your projects are short, simple cuts with no effects, maybe you can get away with 16GB. But modern 4K video, especially if you shoot in log or high bitrate formats, demands more. And nobody plans to make a simple project — then you add a vignette, a blur, a title, and suddenly you’re in swap hell.

Future You deserves 32GB. Don’t save $60 now and curse yourself for the next two years.
