2 spec wins — AMD Ryzen 7 7840U7 spec wins — Apple M3 Max (16-core)
InnoReviews verdict
Apple M3 Max (16-core) wins this laptop processor face-off, 69.6 to 54.5, pulling ahead mainly in Multi-core (+30) and efficiency (+20). AMD Ryzen 7 7840U still makes sense if its price or standout specs fit your needs better.
Editor's note
A thin-and-light chip against a workstation chip — the M3 Max nearly doubles the multi-core score (21,200 versus 11,700), as it should at its class and price. The honest framing: the 7840U lives in $900-1,400 laptops and handles development, office work and even light gaming (its Radeon 780M is the best iGPU of its generation); the M3 Max lives in $3,000+ machines for people who render, compile or edit for a living. Compare wallets first, cores second.
