Rumor: Apple M7 Ultra to Feature Up to 1.5TB Memory
rohanpaul_ai · x · 2026-07-14
Rumors suggest that Apple is developing the M7 Ultra chip, which will support up to 1.5TB of unified memory.
This would push the memory limit of Apple's top-tier Macs to more than double that of the current M3 Ultra. The core driver behind this is local AI: larger models require larger memory footprints to run on-device.
The article also compares the capacity and bandwidth of Nvidia Blackwell B200, RTX 5090, and M3 Ultra. If the rumors are true, the M7 Ultra would position the Mac closer to a server-class workstation. However, its ultimate realization and reasonable pricing will still heavily depend on DRAM supply.
