After three years with the 14” MacBook Pro M1 Max, I decided to upgrade to the new 16” MacBook Pro M4 Max. Apple’s recent announcement of the M4 lineup felt like the right opportunity to make the upgrade, especially with the combination of improved power efficiency, performance, and a larger display. While the 14” form factor is excellent for portability, I’ve found that the extra screen real estate improves my productivity, especially for multitasking across multiple apps. If I’m truly doing something that requires portability, I’ll grab my 11″ iPad Pro M4.

Although benchmarks don’t necessarily reflect real-world performance, here are some objective numbers from Geekbench 6’s CPU and Compute (Metal and OpenCL) tests between my former MacBook M1 Max (10 core CPU, 32 core GPU), current Mac Studio M1 Ultra desktop (20 core CPU, 64 core GPU), and new MacBook M4 Max (16 core CPU, 40 core GPU).
| Geekbench 6 Benchmark | MacBook Pro M1 Max | Mac Studio M1 Ultra | MacBook Pro M4 Max |
| CPU Single-core | 2,435 | 2,405 | 3,735 |
| CPU Multi-core | 12,801 | 18,252 | 25,533 |
| Compute OpenCL | 73,435 | 103,168 | 114,563 |
| Compute Metal | 121,391 | 170,953 | 185,377 |
