iPhone 16's A18 Pro chip outperforms the M1 chip

Original Article ↗ Hacker News Discussion ↗

Apple’s new A18 Pro chip in the iPhone 16 reportedly matches or exceeds the performance of the M1 laptop chip, raising questions about whether this level of power is useful in a phone. Commenters weigh the benefits for on-device AI, computational photography, gaming, and future-proofing against limits like battery, thermals, and iOS’s constrained multitasking. Many argue the real bottleneck is bloated software and locked-down platforms, and some call for phone-as-desktop docks to better exploit this surplus performance.

Perceived Overkill vs Everyday Use

  • Many see M1-class performance in a phone as “obscene” given typical use (messaging, social media).
  • Others argue phones already do heavy work: AR, CAD, video editing, gaming, realtime video transcoding, and complex web apps.
  • Some note even “simple” apps like Instagram, Facebook, and Reddit feel bloated and can lag or drain batteries on modern hardware.

Local AI vs Cloud AI

  • One camp expects AI to remain largely server-side due to higher compute, memory, and cooling headroom.
  • Another emphasizes Apple’s privacy pitch: run as much AI as possible on-device so data stays local, with cloud only for heavier tasks.
  • There’s disagreement on whether network overhead and latency will erase much of the cloud’s raw speed advantage for many tasks.
  • Training is widely seen as cloud-only; inference/object detection is viewed as feasible on low-power devices.

Thermals, Power, and Efficiency

  • Several point out phone compute is thermally and power constrained; peak benchmark numbers can’t be sustained long.
  • Counterpoint: higher peak performance lets the chip finish tasks quickly and sleep, improving efficiency and battery life.
  • Some propose cooling docks or pads (with fans) to unlock higher sustained performance when the phone is docked.

Phone as Desktop Replacement

  • Many want a “single device” that docks to monitor, keyboard, and mouse, effectively replacing laptops.
  • Samsung DeX is cited as a working example; some expect Android 15 to push this further.
  • Skeptics argue:
    • Phones lack the memory/cooling to replace desktops for heavier workloads.
    • Cost, redundancy, and UX (iOS multitasking, cursor model) make it unattractive for most users.
    • Apple has little incentive to cannibalize MacBook sales, though others note accessory and “MacBook-lite” upsell potential.

Gaming and High-End Workloads

  • AAA games can technically run on iPhones, but uptake on ports like Resident Evil has been low; console-centric design and need for controllers are blamed.
  • Some see mobile SoC headroom as valuable for computational photography, 4K/8K video processing, and night-time/plugged-in workloads.

Longevity and Upgrade Behavior

  • “Overkill” today is framed as future-proofing: a powerful phone feels premium and usable 5+ years later.
  • Battery degradation, not raw performance, is often what ultimately drives replacement, with some users choosing battery swaps instead.
