32GB is worth it for 4K video.

Yes, if your 16GB is pegged at 100% while editing, more RAM will smooth things out.

Premiere, DaVinci Resolve, Final Cut—they all love RAM. When you run out, the system starts swapping to your SSD, which is slower and causes hitching, stuttering, and those spinning beachballs. Going from 16GB to 32GB gives your timeline room to breathe, especially with multicam, effects, or high bitrate footage.

That said, RAM isn’t a magic bullet. A slow CPU or weak GPU will still hold you back, and if your footage is HEVC or 10‑bit, decoding power matters just as much. But if your current bottleneck is memory pressure, 32GB is the single biggest upgrade you can make for $50–100.

Do it. Future you will thank you when scrubbing doesn’t feel like wading through mud.
