Apple MacBook Pro (M5 Max)

Apple

M5-generation laptop; bandwidth sits between the M4 Max and the M3 Ultra. M5 base is 153 GB/s, M5 Pro 307 GB/s.

CPU · GPU · NPU 614 GB/s memory bus 128 GB Unified memory
Apple unified. Bus width tracks bandwidth (614 GB/s, sets decode speed); the box tracks capacity (128 GB, sets what fits). Unified memory is one pool shared by CPU and accelerator.
