On which architecture are cache lines not 64 bytes? It's almost universal.

As noted by the other comments, Apple's M-series chips seem to use a 128-byte cache line. ARM doesn't mandate that their licensees must use a pre-specified cache line size: 64 bytes just happens to be the consensus-arrived standard.
