Just not too old. Easy to get into "power usage makes it not worth it" for any use case when it runs 24/7 | |||||||||||||||||||||||||||||

Seriously. 24/7 adds up faster than most realize! The idle wattage per module has shrunk from 2.5-3W down to 1-1.2 between DDR3 & DDR5. Assuming a 1.3W difference (so 10.4W for 8760 hours), a DDR3 machine with 8 sticks would increase your yearly power consumption by almost 1% (assuming avg 10,500kWh/yr household) That's only a couple dollars in most cases but the gap is only larger in every other instance. When I upgraded from Zen 2 to Zen 3 it was able to complete the same workload just as fast with half as many cores while pulling over 100W less. Sustained 100% utilization barely even heats a room effectively anymore! | |||||||||||||||||||||||||||||

Maybe? The price difference on newer hardware can buy a lot of electricity, and if you aren't running stuff at 100% all the time the calculation changes again. Idle power draw on a brand new server isn't significantly different from one that's 5 years old. | |||||||||||||||||||||||||||||

To be clear, this server is very lightly loaded, it's just running our internal network services (file server, VPN/DNS, various web apps, SVN etc.) so it's not like we're flogging a room full of GeForce 1080Ti cards instead of buying a new 4090Ti or whatever. Also it's at work so it doesn't impact the home power bill. :D | |||||||||||||||||||||||||||||
