Apple’s M6 and M5 Ultra Raise the AI Bar
💡Apple’s new chips target faster local AI with 512GB memory and 1.2TB/s bandwidth.
⚡ 30-Second TL;DR
What Changed
M6 debuts as Apple’s first 2nm chip in the new Mac mini.
Why It Matters
The expanded memory capacity and bandwidth could make Apple’s high-end desktops more capable for local model inference and other memory-intensive AI workloads. Developers may be able to run larger models locally, although actual gains will depend on software support and model optimization.
What To Do Next
Benchmark your local models with MLX on Apple silicon to determine whether the M5 Ultra’s memory capacity improves throughput or enables larger model sizes.
