16GB vs 32GB RAM for CAD: 32GB is the new minimum for real work

32GB can double your usable workspace and prevent frustrating lag, while 16GB chokes on large assemblies and simulations. CAD software like SolidWorks or Fusion 360 eats RAM—once you run out, the system swaps to the drive and stutters. 16GB is fine for simple parts, but for a 200-component assembly or running a browser, 32GB is a “why did I wait so long” upgrade.
