Apple M7 Ultra: Up to 1.5TB of Unified Memory Is Under Consideration

Apple M7 Ultra May Support Up to 1.5TB of Unified Memory

Apple, according to Mark Gurman’s Power On newsletter, is developing the future M7 Ultra chip with support for up to 1.5TB of unified memory. For now, it is primarily linked to a new server product from the company. If such a configuration reaches a shipping device, Apple Silicon would for the first time match the maximum RAM capacity of the top-end 2019 Intel Mac Pro.

Memory capacity has long been one of the more noticeable compromises of Apple Silicon computers. In these systems, memory sits close to the processor and works as a single pool for the CPU, GPU and other units. This delivers very high bandwidth, but it also makes scaling more difficult: the maximum capacity depends on the architecture and layout of the entire system.

According to Gurman, Apple is designing the M7 Ultra with support for up to 1.5TB of memory — roughly twice the amount rumored for the future M5 Ultra. However, a launch is not guaranteed: a global memory shortage has made suitable chips more expensive and harder to source, so the final decision will depend on market conditions.

Apple has already reduced the highest-capacity Mac Studio configurations. The company first removed the M3 Ultra option with 512GB of memory, then the 256GB version also disappeared. As a result, the M3 Ultra lineup was left with a 96GB configuration. The Mac Studio with M4 Max could previously be ordered with up to 128GB. The M5 Ultra is expected later in 2026 and is rumored to support up to 768GB of unified memory — if released, that would set a new record for Apple Silicon.

If Apple does launch a device based on the M7 Ultra with 1.5TB of memory, the price of that configuration would almost certainly be extreme. Using a rough estimate of $25 for each additional gigabyte, moving from 128GB to 1.5TB could cost about $35,200. This is only an estimate: there is no official price, and the product itself has not been confirmed.
