16GB will make a noticeable difference for 1080p Resolve.

Yes. Going from 8GB to 16GB on that laptop will cut preview lag significantly—not eliminate it completely, but you’ll actually be able to edit without constant stuttering.

DaVinci Resolve eats RAM for breakfast, especially once you add any color grading, Fusion effects, or timeline previews. 8GB is basically the bare minimum to launch the app. At 1080p you’re not asking for much, but 8GB gets eaten by the OS and Resolve simultaneously, leaving nothing for smooth playback. You’ll see dropped frames and long render pauses.

16GB gives you breathing room. The CPU and GPU in that laptop are solid, so the RAM is the bottleneck. Doubling it should make preview scrubbing and playback much smoother for typical 1080p timelines. You’ll still get lag with heavy effects or multicam, but for basic editing it’ll feel like a new machine.

Just make sure your laptop supports dual-channel memory (two sticks of 8GB) for maximum benefit. And if you can swing 32GB later, even better—Resolve loves excess RAM like a goldfish loves a big bowl.
