Bandwidth basis
68 GB/s is the figure the llama.cpp #4167 scoreboard prints for both the 7-core and 8-core GPU M1, and it is Apple's published unified-memory bandwidth for the base M1 (LPDDR4X-4266). One die, two GPU bins; they share this bandwidth, so they share this record.
Unified memory
yes
Consumer part
yes
notes
Base M1 as binned in the #4167 scoreboard: 7-core GPU and 8-core GPU, both at 68 GB/s. Up to 16 GB unified memory. The 7-core bin is the entry MacBook Air; the 8-core bin is the Mac mini / 13-inch MacBook Pro / iMac. M1 Pro and M1 Max already have their own records. memory_bus_bit is null: Apple publishes bandwidth, not a bus width, and none is back-computed here.
