"Compared to that, Anker’s $49 USB charger has one of Cypress Semiconductor’s CYPD4225 USB-C microcontrollers, which is based on a Cortex-M0 CPU running at 48 MHz. Right off the bat, the USB charger enjoys nearly a 48× improvement in clock speed. More significant, however, is the fact that Cortex-M0 executes most instructions in a single cycle, not dozens of cycles like the AGC. Assuming that ARM instructions are more or less equivalent to AGC instructions – and they are – that works out to well over a 500:1 ratio in performance. "
OK, now that's just showing off.

Here's a portmanteau I'd never seen before:

Funnily enough, I've frequently used the word 'strewth', but didn't know what a portmanteau was until today.

"Struth" is usually how I've seen it. It's very common in Oz.
