Apple’s M1 Compared to 1985’s ARM1

Ken Shirriff, on Twitter:

With Apple’s recent announcement of the ARM-based M1 processor, I figured it would be interesting to compare it to the first ARM processor, created by Acorn Computers in 1985 for the BBC Micro computer. Designers were Sophie Wilson and Steve Furber.

Here are the two dies at the same scale. The M1 is over twice as large physically as the ARM1. It has 16 billion transistors vs 25,000 for the ARM1. If you built the ARM1 using the same technology, it would be a pixel-sized speck.

Lots of fun details in the thread.
