How the iPhone 4S compares to today

A 16 GB Apple Silicon MacBook Pro has about 32× more memory than this device shipped with.

At 800 MHz, the clock is roughly 4.0× slower than a single performance core of a 16 GB Apple Silicon MacBook Pro — and that is before counting cores, width and IPC.

This held about 4,100 modern phone photos — a respectable library even today.

Launched at $649 in 2011 — about $922 in today’s money (approx., US CPI).

Cross-architecture speed figures are clock-only and approximate; inflation figures use US CPI.
