Apple announced that its upcoming M7 Ultra chip will be engineered to support up to 1.5 TB of unified memory, doubling the 768 GB limit of the forthcoming M5 Ultra and matching the highest‑end 2019 Mac Pro configuration. Information came from Mark Gurman’s Power On newsletter.

Unified memory is soldered directly onto the processor die, giving speeds that outpace external modules but tying capacity to die size. That design has capped Apple silicon at lower memory tiers. Gurman noted that a 1.5 TB option “might not launch because of the ongoing memory shortage,” but the chip is already built to accommodate it.

Previous Apple silicon models have seen gradual cuts: the M3 Ultra dropped the 512 GB and 256 GB variants, leaving 96 GB as the top tier, while the M4 Max tops out at 128 GB. The new M5 Ultra will debut later this year with a record 768 GB.

For professionals who run memory‑intensive workflows, the ability to add 1.5 TB would erase a major bottleneck. At roughly $25 per GB, upgrading from a base 128 GB would cost over $35 000. The upgrade closes the long‑standing gap between Apple silicon and legacy Intel rigs, but shortages could delay the full configuration from reaching the market.
