Between the M3 and M4 Pro, the M3 comes out ahead in tdp, while the M4 Pro wins on cores and cinebench r23 (multi). Overall, the M3 scores 43.6 and the M4 Pro scores 49.6 on our Mars Score.
Which should you buy?
The M4 Pro edges ahead on the Mars Score (43.6 vs 49.6), but the 6.0-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the M3 if you care most about tdp. The biggest gaps in its favor are tdp.
Pick the M4 Pro 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 cores, cinebench r23 (multi), l3 cache, among others.
There are no meaningful ties on the headline specs — every popular-comparison metric has a winner.
Bottom line: the M4 Pro is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
