Apple appears to be preparing an M4 Ultra version of the Mac Pro, based on its silicon release cadence and increased industry demand for local AI-powered workflows. Although Apple has not made any official announcements, reputable analysts and Apple’s silicon roadmaps both point toward an upgraded tower built around the new M4 architecture.
Current State of the Apple Silicon Mac Pro
Apple’s most recent Mac Pro is powered by the M2 Ultra and offers:
-
Up to a 24-core CPU and 76-core GPU
-
Up to 192GB unified memory
-
Six PCIe Gen4 slots for internal expansion
However, the M2 Ultra Mac Pro does not support third-party discrete GPUs and delivers performance similar to the Mac Studio, raising questions about whether Apple will skip an M3 refresh and jump directly to an M4 Ultra.
Why an M4 Ultra Mac Pro Is Highly Likely
-
Faster Neural Engine supports more demanding on-device AI and ML tasks
-
Second-gen 3nm architecture improves sustained performance and efficiency
-
PCIe + unified memory combination remains exclusive to the Mac Pro
-
Greater separation from Mac Studio, which may also receive M4 Ultra
What Current Reports Indicate
Throughout 2024, leading Apple analysts have reported that the M4 family will roll out across the Mac lineup through 2025. Several of those reports suggest that the Mac Pro will skip M3 entirely and receive an M4 Ultra refresh to better serve high-end professional workloads.
Expected Features of an M4 Ultra Mac Pro
CPU & GPU Architecture
-
Dual-die UltraFusion design
-
Higher IPC and greater efficiency
-
Advanced ray-tracing and graphics acceleration
Neural Engine & AI Capabilities
-
Higher TOPS for Stable Diffusion, Transformers, and video analysis
-
Optimized Core ML and Metal Performance Shaders
Memory & Throughput
-
192GB (or more) unified memory configuration
-
Faster ProRes, HEVC, and AV1 media engines
Expansion & I/O
-
Multiple PCIe Gen4 (or higher) slots
-
Updated Thunderbolt and USB controllers
-
No support for discrete GPUs (likely)
When Could Apple Release It?
Apple typically brings new Ultra chips to the Mac Studio before the Mac Pro, allowing time to validate yields and performance. If an M4 Ultra Mac Pro is on the roadmap, it will most likely arrive in the late phase of the M4 product cycle, potentially late 2025.
Mac Pro vs Mac Studio: Who Gets the M4 Ultra First?
Apple will almost certainly ship the M4 Ultra in the Mac Studio first, then release the Mac Pro version. For users who need internal PCIe expansion, the Mac Pro will remain the only option.
Should You Buy Now or Wait?
| Situation | Recommendation |
|---|---|
| You need PCIe slots immediately | Buy the M2 Ultra Mac Pro |
| Your work is heavy on AI/ML and you can wait | Hold out for the M4 Ultra |
| You don’t need PCIe slots | Consider the Mac Studio |
FAQs
