In 2003, Apple released a 64-bit dual-core 1.8Ghz system: Power Mac G5.

In 2023, Apple released a 64-bit dual-core 1.8Ghz system: Apple Watch Series 9.

The Watch is faster and has more RAM.

The G5 was too hot to put in a laptop. It'd use up S9's battery in under 2 minutes.

@kornel Good news is that we can put 2GHz system into smartwatch. Bad news is that people are putting 2GHz systems into smartwatch, that 2GHz CPUs are now required for displaying time :-(. You know, battery life still suffers with 2GHz CPUs.You can get month with bangle.js2, or day with Apple...
@pavel @kornel the good news is my Apple Watch does a lot more than tell the time.
@Strwpok @kornel Does Apple watch do anything that should require 2GHz CPU? (Does it even run doom? :-) )
