The entry point to capable Apple unified-memory inference: up to 64 GB at 273 GB/s. Bandwidth, not capacity, is the limiter here.

CPU · GPU · NPU 273 GB/s memory bus 64 GB Unified memory
Apple unified. Bus width tracks bandwidth (273 GB/s, sets decode speed); the box tracks capacity (64 GB, sets what fits). Unified memory is one pool shared by CPU and accelerator.

Ceiling is the theoretical rooflineruntimeA performance model that bounds throughput by either compute or memory bandwidth, whichever is the limiting resource for an operation's arithmetic intensity.
