I upgraded from an M1 Pro to the M3 Max six months ago. As a developer running Docker containers, local LLMs, and heavy builds, here is my honest take.
The Good: Speed
Our main project’s build time went from 4 minutes (M1) to 1 minute 45 seconds. Over a day, that saves me about 20 minutes of staring at terminal progress bars.
The Bad: Battery Life Impact
The M3 Max is thirsty. While my M1 Pro could genuinely last an 8-hour workday, the M3 Max gets me about 5-6 hours if I’m pushing it. It’s still better than any Windows laptop I’ve used, but it’s a regression.
The RAM Upgrade
I went for 64GB of Unified Memory. This was the biggest quality of life improvement. I can keep Docker, Chrome (50 tabs), VS Code, and a local Llama-3 model running simultaneously without swapping.
Verdict
If you are on an M1 or M2 Pro, you probably don’t need to upgrade unless you really need the GPU power or compile massive codebases. But if you are coming from Intel? It’s a whole new world.
