Cheaper to start
MacBook Pro 16" M4 Max
Starts about $100 lower.
Rated higher
Apple MacBook Pro 16" (M3 Max)
9.8 vs 9.2 on our design scale.
Standout
Apple MacBook Pro 16" (M3 Max)
400GB/s memory bandwidth eliminates LLM bottlenecks
Apple MacBook Pro 16" (M3 Max)
The definitive mobile workstation for local AI development. Powered by the M3 Max chip with a 40-core GPU and up to 128GB of unified memory running at 400GB/s, it runs massive LLMs entirely on-device without thermal throttling.
