MacBook Pro buyer weighs 48GB vs 64GB

Hot take: for local model work, memory headroom matters more than most first-time buyers expect, so 64GB is the safer choice if the budget stretch is tolerable.

• –48GB is enough to learn the basics, run smaller models, and experiment without immediately hitting the wall.
• –64GB becomes valuable fast once you start juggling larger models, longer context windows, or other apps at the same time.
• –On Apple silicon, unified memory is shared by the system and the GPU, so “RAM” pressure shows up sooner than on a desktop with discrete VRAM.
• –If this laptop is meant to be a serious local-model machine rather than a casual test bed, the extra 16GB is not cosmetic.
• –If cost matters more than headroom, 48GB is still a sensible entry point, especially if the saved money goes toward storage or staying within budget.
