M7 Ultra Might Pack 1.5TB RAM, Narrowing Apple Silicon’s Memory Gap

Mark Gurman’s Power On suggests Apple’s upcoming M7 Ultra could support up to 1.5TB of unified memory, potentially matching the top RAM of the 2019 Mac Pro. While this would close a long-running Apple Silicon limit, supply constraints and strategic decisions could affect whether the 1.5TB option ships. Apple’s roadmap reportedly includes an M5 Ultra with up to 768GB, and the high-end RAM upgrade from 128GB would be very expensive (estimates exceed $35,000) if offered.
