Apple is building a chip that could hold 1.5 terabytes of unified memory. That’s not a typo, and it’s not a spec for a data center rack. It’s for a desktop computer.
According to Mark Gurman’s Bloomberg Power On newsletter from July 12, the M7 Ultra is slated for a 2028 release and aims to deliver AI performance “closer to” Nvidia’s Blackwell-class accelerators.
What Apple is actually building
The M7 Ultra’s 1.5TB unified memory target represents roughly double the capacity of the current M5 Ultra. To put that in perspective, it matches the highest RAM configuration Apple ever offered on its 2019 Intel Mac Pro.
Unified memory lets the CPU and GPU share the same memory pool, which eliminates the bottleneck of shuttling data between separate chips. For running large language models and AI inference workloads, that architectural choice matters enormously.
