Power usage between i3 and Xeon (in practice)

[MisterE2002]

Long story short. Had the C2550D4I. Broke because of the Atom C2000 bug.
Delivered to the Store for warrenty and after a week the store was bankrupt :(
So the question remain IF or WHEN i got a replacement. And even then i do not know if it will be a ticking bom again.

So, i am thinking about this popular mini itx motherboard: E3C226D2I
My memory (CT102472BD160B) seems supported.

I'm torn between the i3-4370 and the Xeon E3-1231 v3. A price difference of 130 Euro.
The main question i have is about the TDP. Idle should be about the same.
But when (in practice) will the Xeon consume more than the i3?
Is this some kind of logical scale? Of will it directly use the 80Watt?
If i use a couple of modest Dockers do the consume about the same?

Your useage would be a better determining factor on what CPU you get. Do you plan on running a lot of containters and/or VM's (Corral) or jails (9.10) or is this just a basic file server?

Idle will be slightly higher, since Xeons have four cores. It's probably a small difference, certainly less of an impact than the BMC.

But when (in practice) will the Xeon consume more than the i3?

Instantaneously, whenever It's loaded. Integrated over time, I wouldn't be surprised if the Xeon ended up being more power-efficient.

Of will it directly use the 80Watt?

No, the 80W are a reference.

My Supermicro 1U with dual Xeon L5630 CPUs idles around 120 watts. Under load it might approach 200 watts. My wife's PC with a newer gen i3 idles around 32-36 watts.
