Apple abandoned plans for a high-performance “M3 Extreme” processor that was intended to power a flagship Mac Pro, according to reporting from Bloomberg’s Mark Gurman. The company canceled the project due to high production costs and limited market demand, opting instead to transition its desktop lineup toward the more accessible Mac Studio.
The Rise and Fall of the M3 Extreme
For years, Apple explored a top-tier silicon architecture designed to surpass the capabilities of its “Ultra” chips. Rumors surrounding an “Extreme” tier first surfaced in 2022, when reports indicated the company was developing an M2-based version for the Mac Pro. That design reportedly aimed for 48 CPU cores and 152 GPU cores—double the capacity of the M2 Ultra.
The M3 iteration followed a similar trajectory. According to Gurman, this chip was engineered to offer twice as many CPU and GPU cores as the M3 Ultra, which currently tops out at 32 CPU cores and 80 GPU cores. Despite the potential for significant performance gains, Apple shelved the project. The primary deterrent was the manufacturing cost, which would have pushed the retail price of an M3 Extreme-equipped Mac Pro to at least $10,000 before any hardware upgrades.
Did you know?
Apple’s 2023 Mac Pro transition to silicon retained the tower’s PCIe expansion slots but utilized the same M2 Ultra chip found in the significantly smaller, less expensive Mac Studio.
Engineering Challenges and Market Realities
Apple determined that the development costs required to bring such a specialized chip to market were difficult to justify for a product line that sells in relatively small volumes.
While the Mac Pro offered unique hardware expansion capabilities, the performance parity between it and the Mac Studio—both running on the M2 Ultra—left the Mac Pro struggling to justify its higher price point to professional users.
Why the Mac Pro Lost its Performance Edge
The absence of the Extreme chip left the Mac Pro without a distinct performance advantage over Apple’s smaller desktop offerings. While the Mac Pro launched in 2023 with the M2 Ultra, it remained tethered to that hardware until the product line was discontinued in March. The cancellation of the M3 Ultra Mac Pro, which also reportedly never reached production, signaled a cooling of development for the desktop tower.
Pro Tip:
If you rely on heavy PCIe expansion for specialized audio or video hardware, the legacy Mac Pro remains a unique, albeit discontinued, option. For raw processing power, the M3 Ultra-equipped Mac Studio currently serves as the top-tier benchmark in Apple’s active desktop lineup.
Frequently Asked Questions
Why was the M3 Extreme chip canceled?
Apple canceled the chip primarily due to high production costs and limited demand for a machine that would have carried an estimated base price of $10,000.
Is the Mac Pro still available?
Apple discontinued the Mac Pro earlier this year, and there are currently no indications that the product line will return to the market in the near future.
How did the Mac Pro compare to the Mac Studio?
While the Mac Pro featured PCIe expansion slots, it utilized the same M2 Ultra chip as the Mac Studio, resulting in near-identical performance despite the Mac Pro’s significantly higher price tag.
