Apple’s mac pro obsolescence: a secret history of discarded ambition

Apple quietly shelved a revolutionary processor tier and two entire Mac Pro models, effectively killing off the once-flagship desktop – a stunning testament to shifting priorities and a costly gamble.

The ‘extreme’ chip that never was

Bloomberg’s Mark Gurman has unearthed a fascinating, and frankly embarrassing, chapter in Apple’s design process. Before the Mac Pro was relegated to the graveyard of discontinued products in March, the company was actively developing an ‘Extreme’ chip – a successor to the Ultra, boasting roughly double the processing and graphics power. Two physical prototypes were built, a clear indication of a serious attempt to push the boundaries of Apple Silicon.

But the allure of ‘Extreme’ proved too expensive, too complex, and ultimately, too demanding of market appetite. Apple wisely – or perhaps brutally – pulled the plug, effectively burying the ambition along with the Mac Pro itself. The resulting scrapped chip tier represents a significant investment, a tangible loss of potential performance headroom.

More than just silicon: lost mac pro designs

The story doesn't end with the chip. Gurman’s reporting reveals that Apple also conceived of two distinct Mac Pro models – internally designated J170 and J190 – catering to different user needs. J170 was a surprisingly Intel-based design, built even after Apple’s complete commitment to its own silicon architecture. J190, however, was an M3 Ultra variant intended to launch alongside the M3 Ultra Mac Studio in early 2025. Both projects have now been consigned to the digital dustbin.

A price too high for the flagship

The Mac Pro’s demise wasn’t simply a matter of bad timing. The machine, running a 2023 M2 Ultra chip, was lagging significantly behind the rapidly evolving Mac Studio, which consistently received updates. And the price differential – a staggering double the cost of the Studio for essentially comparable functionality – proved unsustainable.

Apple’s strategic shift is now clear: focus on the Mac Studio as the premium desktop offering, leveraging its established ecosystem and streamlined design. The discarded ‘Extreme’ chip and Mac Pro models serve as a stark reminder of the ruthless pursuit of efficiency and profitability that drives even the most innovative companies.

New Mac Studios with M5 Ultra chips are slated to arrive as early as this fall, a testament to Apple’s ongoing investment in its desktop lineup – albeit one built on the foundation of a spectacularly failed gamble.
