Your post is alas quite inaccurate. You are describing the traditional architecture, which is not state of the art anymore. Budget x86 platforms have been using unified memory for over a decade now (as a means to reduce costs rather than improve efficiency), and unified memory is a standard approach in contemporary supercomputing. Nvidia for example has supported unified virtual memory for many years now - a feature that Apple still lacks. And while Apple does offer unified physical memory, the bandwidth is still relatively low, and although copies can be elided under some circumstances, it does not mean that they will be always elided. Finally, we now have other vendors building AI-focused workstations with similar memory architecture but better performance and features.
All in all, the current Mac Pro has very poor value proposition, unless you are heavily invested into the ecosystem and need PCIe expandability.
Doesn’t matter if there are minor variations. Apple Mac Ro doesn’t really fit Apple silicon strategy. Apple has to solve pcie expansion and discrete GPU problem.
Let me step back and add history and context because people are mixing two very different eras of the Mac Pro.
During the Intel era the Mac Pro was built like a traditional workstation. You bought CPUs from Intel, GPUs from AMD or Nvidia, added RAM sticks, PCIe cards, RAID cards, audio cards, capture cards and sometimes external GPUs. Studios used it for film, music, science and 3D work because software and hardware evolved separately. Apple’s job then was mostly integration and industrial design.
Apple Silicon changed that model completely. Apple moved the CPU, GPU, memory and media engines onto one chip. This wasn’t about being cheap. It was about speed, power efficiency and removing bottlenecks. Unified memory here is not just “shared RAM.” It is very high-bandwidth memory tightly coupled to the chip. Designed so the CPU, GPU and AI engines see the same data instantly. That is why Apple Silicon Macs can do things Intel Macs needed much more power and cooling to do.
Because of this shift the role of the Mac Pro changed. In the Apple Silicon era most users who used to “need” a Mac Pro actually don’t anymore. A Mac Studio can now handle video, audio, coding and even 3D work that once required a tower. The Mac Pro today exists mainly for PCIe expansion: broadcast cards, specialty audio, networking and legacy workflows & not raw compute.
Apple didn’t “fail” to make the Mac Pro better. They pivoted the entire platform. The Mac Pro is no longer the center of innovation. It is the compatibility bridge for industries that still need slots.
Now about other companies that Apple used to buy parts from.
What Apple did with Apple Silicon forced the entire industry to react:
- Intel added hybrid CPUs (performance + efficiency cores).
- AMD pushed chiplets and better power efficiency.
- Nvidia leaned harder into CPU-GPU memory sharing and AI acceleration.
- ARM vendors (Qualcomm, MediaTek, others) are now building PC chips that copy Apple’s focus on performance per watt and tight integration.
Five years ago none of these was mainstream on PCs. Today it is.
Looking five years ahead I expect:
- More systems that look like “SoC-first” designs even in workstations
-Faster shared memory between CPU, GPU and AI engines
-Fewer upgradable parts but much higher baseline performance
-Expansion moving outward (network & external accelerators) instead of inside the box
No doubt that the current Mac Pro has a narrow audience and Apple knows it. That’s intentional. The future of the Mac is not modular towers but it’s highly integrated systems where most people no longer need one.
The mistake is judging the Apple Silicon Mac Pro by Intel-era rules. Apple already moved on & others are following.
