How Apple’s M1 chip redefined the iPad — and what comes next for the Mac, iPhone, and beyond
2020: The Silicon Revolution Begins
In June 2020, at its WWDC keynote, Apple officially announced a seismic shift — Macs would move away from Intel processors and adopt custom-designed Apple Silicon, beginning with the M1 chip.
By November 2020, Apple delivered with three devices running the first-generation M1:
- MacBook Air (M1, Late 2020)
- MacBook Pro 13-inch (M1, Late 2020)
- Mac mini (M1, Late 2020)
These machines were instantly praised for their high efficiency, faster performance, and industry-defying battery life, largely due to the M1’s 5nm architecture, unified memory, and tight hardware-software integration.
2021: iPad Pro Meets the M1 – A Fusion of Power and Portability
In April 2021, Apple introduced the iPad Pro (M1, 2021) — the first iPad to feature the same M1 chip found in the MacBook lineup. Available in 11-inch and 12.9-inch variants, this version blurred the line between tablet and laptop.
Key highlights:
- Same 8-core CPU and 8-core GPU as MacBook Air and Pro
- Up to 2TB of storage and 16GB of RAM
- Thunderbolt/USB 4 port for high-speed data and external displays
- Liquid Retina XDR display (12.9″ model) for HDR workflows
- Compatibility with Magic Keyboard and Apple Pencil 2
This iPad Pro model was effectively a MacBook Pro without macOS, running iPadOS, which began to show signs of being limited by software rather than hardware.
2021–2022: M1 Expands Its Reach
After the iPad Pro, Apple further expanded the M1 lineup:
- iMac 24-inch (M1, 2021) – A colorful all-in-one for home and creative users
- iPad Air (M1, 2022) – Brought Mac-level power to a mid-range iPad
- MacBook Pro 14-inch & 16-inch (M1 Pro / M1 Max, 2021) – Designed for creative professionals needing more CPU/GPU cores, more RAM (up to 64GB), and superior external display support
This period saw Apple stretching the M1 architecture into multiple tiers:
- M1 – for consumers
- M1 Pro – for advanced users
- M1 Max – for high-end creators
- M1 Ultra – for workstation-class users (as seen in Mac Studio, 2022)
iPhones Don’t Use M1 — But Share the DNA
While iPhones didn’t get the M1 chip, they already had their own Apple Silicon lineage. The iPhone 12 (2020) launched with the A14 Bionic, the first 5nm smartphone chip, and its successor the A15 Bionic (iPhone 13) shared many architectural traits with the M1.
These chips, although not named “M1,” are part of the same family of custom ARM-based designs optimized for iOS and power efficiency.
2023–2024: From M1 to M2 and M3
Apple introduced the M2 chip in June 2022 with improvements over M1 in CPU (18% faster), GPU (35% faster), and memory bandwidth. It launched in:
- MacBook Air (M2, 2022)
- MacBook Pro 13-inch (M2, 2022)
- iPad Pro (M2, 2022) — Successor to the M1 iPad Pro
In 2023, Apple leapfrogged to the M3 series, built on 3nm process, delivering even better efficiency and performance.
Devices launched with M3 include:
- iMac 24-inch (M3, 2023)
- MacBook Pro 14/16-inch (M3, M3 Pro, M3 Max, Late 2023)
What’s Coming: The Future of Apple Silicon
Apple’s trajectory indicates a few major expectations in the coming years:
- M4 Series Launch (Expected Late 2024–2025)
- Leaks and insider reports suggest Apple is preparing M4 chips with more AI acceleration for on-device machine learning, possibly tying into Apple Intelligence (their new AI platform).
- iPadOS and macOS convergence
- While hardware now shares the same chip, software differences limit potential. Developers and users continue to hope for better pro-app support (like Final Cut, Xcode) and greater file system access on iPadOS.
- iPhones with on-chip AI cores
- The upcoming iPhone 16 (expected September 2025) is rumored to bring a chip heavily optimized for generative AI, built on learnings from M-series neural engines.
- Expanded Apple Vision Pro support
- The Apple Vision Pro (launched with M2 and R1 chips) is expected to benefit from future chips that better handle spatial computing and real-time rendering.
Bottom Line: The M1 iPad Was a Turning Point
The iPad Pro M1 (2021) was more than a spec bump — it marked the beginning of a future where iPads, Macs, and even mixed-reality devices run on a shared performance architecture.
M1 proved that high-end processing doesn’t need fans or bulky hardware. And even as M2 and M3 take center stage, M1 remains a reference point for efficient, powerful mobile computing — still present in entry-level Macs and iPads today.
Apple’s silicon roadmap has not just redefined their own devices but pushed the entire industry to rethink what’s possible in a chip.
