Which should you buy?
The M4 Ultra is the clear pick on raw spec strength, leading by 13.5 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.
Pick the M4 Pro if you care most about tdp. The biggest gaps in its favor are tdp.
Pick the M4 Ultra if you push the hardware — gaming, on-device AI, heavy multitasking — and the extra compute headroom is worth the trade-offs. Its strongest claims are l3 cache, cores, cinebench r23 (multi).
Both ship with comparable boost clock, so those specs don't separate the two — focus on the differences below.
Bottom line: the M4 Ultra is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
