Apple Silicon -- Update -- After The Apple Presentation -- September 10, 2025

Locator: 49060APPLE. 

Wiki. Has not updated N1 yet.

Thread for developers on Apple. Link here.

Lots of "stuff" here to unwind, but the bottom line for me, Apple:

  • slow, methodical; one chip at a time; one partner at a time;
  • continues to embed the iPhone into one's daily life; and,
  • is laser-focused on privacy and cost.

And continues to explore AV/AR. Right now Meta seems to have the lead and yet Meta's AV/AR seems to be a "toy" compared to Apple's vision. No pun intended.

APPLE SILICON

ChatGPT prompt:

Apple presentation regarding Apple Silicon: were there any other chips introduced other than the N1, C1MX, A19, A19Pro?

ChatGPT reply:

You’re absolutely on the mark—and it’s a great question. Beyond the A19 and A19 Pro (the main iPhone SoCs), the Apple presentation—especially for the iPhone 17 and iPhone 17 Air—also introduced two significant new in-house chips.

New chips introduced:

  1. N1 – a brand-new wireless networking chip built by Apple.

    • Replaces components previously sourced from Broadcom.

    • Provides Wi-Fi 7, Bluetooth 6, and Thread support.

    • Enhances connectivity performance and reliability—including improvements to AirDrop and Personal Hotspot.

  1. C1X – a next-generation 5G cellular modem designed by Apple.

    • Promises up to 2× faster speeds than its predecessor, the C1.

    • Offers notably improved energy efficiency (up to 30% less energy use).

ChatGPT prompt:
  • These new chips: impact on Wi-Fi 7 and Thread enable?

ChatGPT reply:

Impact of thread (via N1):

Wi-Fi 7 is the first real generational leap since Wi-Fi 6, and Apple is positioning the N1 as the enabler:

  • Speed – up to ~5× faster than Wi-Fi 6 under ideal conditions (think multiple gigabits per second).

    → Big for iCloud backups, AR/VR streaming, and Apple Vision Pro integration.

  • Lower Latency – crucial for FaceTime, gaming, or collaborative apps.

    → Makes the iPhone behave more like a wired connection when on strong Wi-Fi.

  • Multi-Link Operation – Wi-Fi 7 can use multiple bands (2.4 GHz, 5 GHz, 6 GHz) simultaneously.

    → iPhones can hold a rock-solid connection even in congested networks (airports, conferences).

Impact of Thread (via N1)

Thread is a low-power mesh networking protocol for smart-home devices (part of the Matter standard).

  • Direct Smart Home Control – Your iPhone becomes a Thread border router, meaning it can directly control smart bulbs, locks, thermostats without relying on a HomePod or Apple TV.

  • Energy Efficiency – Thread devices sip power. This makes iPhones better at acting as the roaming “brain” in a Matter-enabled home.

  • Resilience – Unlike Wi-Fi or Bluetooth alone, Thread creates a self-healing mesh. So if one node goes down, others still communicate.

Why this matters in Apple's world:

  • Short Term: Faster Wi-Fi for backups, sharing, and Apple Vision Pro tethering.

  • Medium Term: Your iPhone becomes the universal remote and hub for Matter smart homes.

  • Long Term: Apple is building an ecosystem where every device (watch, phone, Vision Pro, smart home) talks seamlessly without third-party silicon.

    👉 So the N1 isn’t just about performance — it’s Apple bringing connectivity in-house, the same way Apple Silicon CPUs freed them from Intel.

ChatGPT prompt: what does Apple gain by ditching Broadcom for this N1 chip (beyond just features?)

ChatGPT reply:

Control over the stack:

  • With Broadcom, Apple was tied to a third-party roadmap.

  • Now Apple can synchronize networking with its A-series chips, modems, and NPUs, tailoring power management, antenna tuning, and latency for its own use cases (AirDrop, Vision Pro streaming, HomeKit/Thread).

  • It’s the same playbook Apple used when it ditched Intel for Apple Silicon — vertical integration means performance and efficiency optimizations that competitors can’t easily match.

Cost and supply chain independence:

  • Apple was spending billions annually on Broadcom components.

  • By designing N1 in-house, Apple reduces reliance on an external vendor, gains pricing leverage, and de-risks supply chain constraints.

  • Over time, this lowers per-unit costs and keeps Apple’s enormous gross margins intact.

Ecosystem lock-in:

  • N1 isn’t just a Wi-Fi chip — it’s a gateway to Wi-Fi 7 + Bluetooth 6 + Thread.

  • Apple can tune these protocols to just work better in Apple-to-Apple scenarios (AirDrop faster between iPhones, smoother Vision Pro tethering, better AirPlay).

  • That strengthens the “only Apple talks to Apple this well” moat.

Freedom to innovate beyond standards:

  • Broadcom has to design chips that serve all customers (Samsung, Google, routers, etc.).

  • Apple can add proprietary features on top of Wi-Fi/Thread standards (for instance, prioritizing Vision Pro streams, or enabling peer-to-peer gaming/AR modes).

  • This lets Apple differentiate at the connectivity layer, which was impossible when they were tied to Broadcom’s generic roadmap.

Strategic leverage against partners:

  • Broadcom still supplies other components (e.g., RF chips). By showing it can replace Broadcom in a key domain, Apple strengthens its hand in negotiations.

  • Just like it did with Intel, Imagination (GPU IP), and Qualcomm (modems), Apple signals: “If you overcharge us or slow us down, we’ll build it ourselves.”

Platform for the future (IoT + AR/VR:

  • Thread support means Apple can quietly make the iPhone the default hub for the Matter smart-home ecosystem, displacing Amazon and Google.

  • Ultra-fast Wi-Fi 7 + custom optimizations mean better AR/VR performance when pairing iPhones with Vision Pro or future glasses.

 Bottom line

  • Ditching Broadcom gives Apple strategic autonomy, higher margins, ecosystem lock-in, and a new platform for smart homes and AR/VR — all in one move. The technical features are just the visible surface; the real win is long-term control.
ChatGPT prompt:

Apple: what is Thread / Part of the Matter Standard?

 ChatGPT reply:

Great question — this is one of those things Apple talks about in a single line during a keynote, but it’s quietly very important.

What is Thread?

  • Thread is a low-power, wireless networking protocol designed for smart-home devices.

  • Think of it as an alternative to Wi-Fi or Bluetooth, but optimized for small, battery-powered devices like sensors, locks, lightbulbs, and thermostats.

  • Key features:

    • Mesh networking → devices connect to each other, not just a central hub. If one device goes offline, the network self-heals.

    • Low latency → faster than Bluetooth for things like turning lights on.

    • Energy efficient → devices can run for years on a coin-cell battery.

Thread + Matter?

  • Matter is a new industry standard for smart-home interoperability, backed by Apple, Google, Amazon, Samsung, and others.

  • Goal: all smart-home devices should “just work” together, no matter the brand.

  • Thread is one of the main transport layers for Matter (alongside Wi-Fi).

So:

  • Matter = the language (common standard).

  • Thread = one of the wires (network technology carrying the messages).

Why Apple cares: 

  • Apple has built Thread into HomePod mini, Apple TV 4K, and now iPhones (via N1 chip).

  • That means your iPhone can become a Thread border router, connecting low-power Matter devices directly without needing extra hubs.

  • Long-term vision: an Apple ecosystem where your iPhone, Watch, and HomePod seamlessly manage your smart home without third-party dependency.

In short:

  • Thread = the networking tech.

  • Matter = the standard that makes devices interoperable.

  • Apple’s N1 chip = makes your iPhone a key player in both.

Bottom line:Apple's N1 chip will make it possible for your iPhone to recognize / activate:
  • a smart lock from Google, a thermostat from Amazon, and a lamp from Ikea, and will control it all from an iPhone?

Right now that can be done through proprietary apps but it's becoming a pain to manage all those apps on the Apple iPhone screen.

The ChatGPT thread continues ... but enough for now.

I'm really, really excited what this all means for Sophia -- age eleven. LOL.
