Other than geek bench and temps, I am also very interested to know the i3 i5 i7 idle and load ampere readings now that it is using desktop CPU instead of mobile CPU. If any one has it already, please share. Thanks!

The i3 is the 8100B which Intel doesn't list (yet?). Basically they're BGA (ball grid array, aka soldered) versions of the desktop chips meant for smaller form factors. I saw somewhere the turbo binning (basically how it balances turbo frequencies vs number of cores in use and heat) is a bit different too but that's hard to find info on.

Not desktop CPU's.

Core i3-8100H TDP 35 Watt
Those are desktop CPUs and the Wikipedia page seems to be wrong. As pointed out before, it's an i3-8100B [1] and that also has a 65W TDP [2], just like i5/i7 (ignore the B, that's just the BGA version but it's not up yet on the Intel site, it's the same chip). The i3-8100H only has 3.0 GHz. Now why [1] shows the i3 as a dual core with HT is anyone's guess...

does anyone with the mm2018 has a watt meter for real idle and load application usage?

the power supply is only 150 watts. barely spiked my UPS load during geekbench tests its has way too many things plugged into it already but load was 26% idle briefly spiked to 42% under geekbench tests.

I mainly use my kill a watt to measure kWhs since I have solar and try to keep track of what is using power. so I don't really pay much attention to instant watts and I am not sure I even know what Amps mean since I never really look at that.

But for my i3 mini, I get
1-2 watts instant when sleeping (.16 amps?)
12 watts or so on, using safari here (.2 amps?)
12-15 booting up and launching apps.

I don't really have anything that would tax this computer; I haven't installed handbrake. I did launch iMovie, and then imported videos, which took all of about 10 secs, so not really a good test, but it seemed to peak at about 37 watts and then dropped below 30.

I will leave the kill a watt plugged in and check back on the kwhs over the next week or month.

Did you ever look back?

my meter shows 72 w full load with 4 ssd's attached and a eGPU (not included in 72w load) , idle it sits around 15-20w, you don't really need a watt meter either. you can use istats , its total power consumption is fairly accurate +/- 5%
