they actually could be made to run at 20 MHz with some software tweaks. But sram is still much less

That's what confused me.

Modern versions of ATMega (ex: the AVR DD) run at 4MHz by default, even if they can go up to 24MHz. Looking back at ATMega328p (which powered the Arduino Uno, aka the one that got popular), the ATMega328p defaults to 1MHz. (IE: 8MHz internal oscillator with 1/8 clock division == 1MHz overall)
