Rumor: Apple M7 Ultra to Support Up to 1.5TB Unified Memory

Between July 13 and 14, multiple posts circulated the same Apple chip rumor: Apple is designing the M7 Ultra chip with a target of boosting unified memory up to 1.5TB, projected for around 2028. Because this figure far exceeds current Mac configurations, the discussion quickly focused on local AI and large model deployment. Currently, this information is based on rumor transcriptions and may be subject to memory shortages, without any official confirmation from Apple.

Key Details and AI Potential

The core detail consistently mentioned is the "1.5TB unified memory." According to @mark_k, if the rumor holds true, the memory limit of Apple's top-tier Mac would significantly exceed the current M3 Ultra. Several authors linked this to local AI: @Hesamation noted that 1.5TB of memory is theoretically sufficient to run models like Kimi or GLM locally, while @AIFlow_ML wondered if it could enable running even larger models on Macs. @mark_k further emphasized that Apple's unified memory architecture allows the CPU, GPU, and Neural Engine to share memory resources, making massive memory configurations particularly valuable for AI scenarios.

Controversies and Doubts

The common premise of all current discussions is "if true." This is more of a potential roadmap for Apple's high-end local computing platform rather than a finalized product spec. While there is significant imaginative space for on-device inference and high-end workstation Macs, the outcome ultimately depends on whether Apple actually launches the M7 Ultra and achieves the 1.5TB target.
