I thought this video was rather interesting, because at 12:27, the presenter crunches the numbers to find out how many years it would take for a new computer purchase to be more environmentally friendly (in regards to total CO2 expended) compared to using a less efficient used model.

Depending on the specific use case, it could take as little as 3 years to breakeven in terms of CO2 if both systems were at max power draw forever, and as long as 30 if the systems are mostly at idle.

This should be a well know, but often misunderstood thing. Lots of reddit selfhosting threds urge people to buy a new mini-pc for its "low power draw" when usually its the same or 1-2watts less then a laptop from 2012. However performace to watt is much higher, so if you need massive preformance new is much better, if your system is idling most of the time anyway, basically no diffrence in buying old

You just can't buy too old or the inverse happens and the performance per watt drops. I think you're right that 2012 is about the cutoff. Maybe 2007 for certain items, like my 2007 iMac. But if you're getting back to the Pentium 4 era you've gone too far and need to turn back around.

Oh god, P4? Yea, those were just 100 watt light bulbs.

Sans the light

My first computer was 33htz. Ran Windows 3.1. And Warcraft 2.

So yeah. The perfect computer.

A 33MHz DX 486was great. If you got stuck with a slower SX CPU, things were frequently not so hot.

[–] kurcatovium@piefed.social 5 points 13 hours ago

Well, I would hope for 33 MHz at least... ;-)
