Apple is developing the M7 Ultra, a next-generation AI-focused processor designed to support up to 1.5TB of unified memory—double the M5 Ultra's planned capacity. Expected in 2028, the workstation-class chip aims to compete with Nvidia's Blackwell accelerators while enabling users to run trillion-parameter models locally. The shift reflects Apple's pivot toward AI-centric design, though memory shortages and pricing concerns could impact availability.

Apple Accelerates M7 Ultra Development for AI Workloads

Apple is fundamentally reshaping its chip roadmap, and the M7 Ultra stands at the center of this transformation. According to Bloomberg's Mark Gurman, the company is skipping expected variants of its M6 chip to fast-track development of the next-generation AI-focused processor

. The M7 Ultra, expected to arrive in 2028, represents a dramatic departure from traditional performance metrics. Where previous generations prioritized processing speeds, graphics capabilities, and battery efficiency, AI-driven hardware demands now dictate design priorities

Finalization of the M7 started just six months after the M6 was finalized, suggesting an unprecedented acceleration in Apple's development timeline

1

. This means M6-powered products will essentially arrive and become obsolete simultaneously later this year, with first M7 products materializing in early 2026, followed by M7 Pro and M7 Max variants at the end of 2027

1.5TB of Unified Memory Targets Enterprise-Class Performance

The headline feature of the M7 Ultra is its staggering memory capacity. The workstation-class chip is being designed to support up to 1.5TB of unified memory, roughly double the capacity planned for the M5 Ultra, which maxes out at 768GB

. This massive memory pool is specifically designed to handle AI workloads at a scale that brings the processor closer to enterprise AI accelerators like Nvidia's Blackwell than traditional desktop chips

The ability to run trillion-parameter models locally depends heavily on memory count and memory bandwidth, not just CPU speeds

3

. With the M3 Ultra already featuring 819GB/s of memory bandwidth, industry observers expect the M7 Ultra could cross into 1TB/s bandwidth territory

3

. To put this in perspective, the M3 Ultra with 512GB RAM can already run DeepSeek's R1 AI model with 671 billion parameters, suggesting the M7 Ultra could handle 1.2 trillion-parameter models with 8-bit quantization

Memory Shortages Threaten Maximum Configurations

Whether Apple can actually ship the full 1.5TB configuration remains uncertain. Widespread memory shortages have made high-capacity components harder to find and significantly more expensive

. The final memory options will depend heavily on the state of the industry when the chip launches

2

. Apple is reportedly testing CXMT DRAM to minimize supply problems, though this may not fully resolve availability constraints

Pricing implications are equally daunting. When Apple last shipped a Mac with 1.5TB of RAM in 2019, that memory alone cost $25,000, with the entire computer reaching $53,000

1

. Recent price increases compound concerns: the base Mac Studio jumped $500 to $2,500, while the higher-end 96GB configuration climbed $1,300 to $5,299

1

. Industry estimates suggest a maxed-out Mac Studio equipped with the M7 Ultra could cost around $20,000

AI-Centric Design Extends Beyond Desktop Macs

The M7 Ultra isn't being built solely for future Macs. Apple plans to use the chip as the backbone of its next-generation AI servers, with an M7 Ultra-powered architecture targeted for deployment around 2029 to help power Apple Intelligence both through on-device AI and cloud-based systems

2

. An M5 Ultra-based server platform is expected to arrive first, providing a stepping stone toward the more ambitious M7 implementation

2

.

This dual-purpose strategy signals that Apple is no longer building chips that happen to support AI—it's building chips around AI

2

. The M7 Ultra is designed to rival Nvidia's Blackwell in AI performance, a significant ambition considering Blackwell processors currently retail for around $12,499.99 . If Bloomberg's roadmap proves accurate, the M7 Ultra won't just be another annual silicon refresh but could mark the point at which Apple's AI ambitions begin to compete with the biggest names in enterprise computing
