Sources: Apple is planning to announce a shift to its own Arm-based processors in Mac computers, replacing chips from Intel, as early as this month at WWDC
- Company readies Macs for next year without Intel processors — Apple is holding virtual version of WWDC event week of June 22
Context & Ripple Effects
This is the confirmation of a two-year leak cycle: Apple's plan to drop Intel was first reported back in April 2018, and by early 2019 developers and Intel officials themselves expected the move. The April 2020 report added the technical detail — three Mac processors derived from the 5nm A14 iPhone chip — so the WWDC timing is the last unknown falling into place.
The stakes for Intel are direct revenue and, more damagingly, the loss of its most visible design-win showcase; for Apple, owning the silicon closes the gap between iPhone and Mac engineering that has been narrowing since the A-series chips first appeared.
First-order effects
- Intel immediately loses the prospect of future Mac socket wins — the 2021 shipment target means current Intel-based Macs become the end of the line, and Intel's Mac revenue runs off over the transition window.
- Mac developers face a forced porting cycle, which Apple is pre-empting with the 'Rosetta 2' translation layer announced at the June 22 WWDC week to keep existing apps running on Arm hardware.
Second-order effects
- Apple's move gives every other PC maker a reference case for Arm-based laptops, putting pressure on Microsoft and Qualcomm's Windows-on-Arm efforts and forcing AMD and Intel to defend the x86 value story on performance per watt.
- Component suppliers tied to Intel's Mac designs lose volume, while TSMC — which builds the 5nm A14-derived processors — gains a flagship customer outside smartphones.
Third-order effects
- If the two-year transition holds, the industry splits further into vertically integrated silicon (Apple designing chips it alone consumes) versus merchant chip vendors selling to everyone else — a structural disadvantage for Intel that compounds across product lines.
- A successful Rosetta-style compatibility bridge would lower the barrier for the next architecture shift, making processor swaps a software problem rather than an ecosystem-breaking event.
The trend: Computing's biggest platforms are converging on custom Arm silicon, with Apple's Mac transition the most complete break yet from merchant x86 processors.
