Dear community,

I am running an Intel P4 prescott with HT on my home server (linux file server on encrypted disks and virtualisation host for three further machines). The performance for this purpose is really okay. When the system is idle it consumes about 140W power.

I am considering buying a new mainboard for an Intel i3-2100T or an Intel i5-2390T. Both are low power CPUs with a TDP about 40W.

Has anyone experiences how much power a recent mainboard with one of these CPUs an 3-4 'green-energy' disks (6W each) consumes? Do I get underneath the 100W threshold?

What's about the performance of these low power CPUs? Are they comparable to an Intel P4 with HT?

regards,
