2 SOURCE-LINKED RELATIONSHIPSM-series generation succession; this is not a claim of shared silicon.
Apple · EvidenceUnder the surface.
Apple disclosed a 100 GB/s unified-memory interface and support for up to 24 GB of unified memory in M2. These are interface and capacity specifications, not independently measured application bandwidth.
CURATOR INTERPRETATIONMore available memory and more interface bandwidth address different bottlenecks. A workload can be limited by capacity, transfers, computation or software; a single specification does not identify which one.
