Sandy/Ivy "T" series or AMD Trinity? Which power efficient CPU choose?

At the moment I have an AMD A10-9700E on an Asus PRIME B350M-A and 8GB of RAM. It also doesn't consume so much power.

I'm running Plex, Gitlab, Nextcloud, Samba, FTP and also have external users and its fast enough for nearly everything.
You also probably could wait for the Ryzen 5 2400GE, for me, it looks like a good alternative.

I use a J4105 board. Power draw is 11W at idle with SSD, one DIMM and 3 slow running case fans. Each HD consumes additional 5Watts. I send them to sleep after 30mins.

I have a Q77 system with an i3-3220T that I use for testing. I recently installed OMV 3.0.99 and ran it for a week:

-- With a 32GB mSata system disk, 4GB RAM, 190 watt 80 Plus Gold Power Supply, and no storage drives connected, idle is just under 11 Watts.
-- Adding three drives (1TB 2.5") set to sleep/spin-down, idle goes up to just over 15 watts.
-- Stess testing, with all cores/threads at 50-60% and with heavy disk I/O, draw goes up to about 35-40 watts.

By comparison, my current "production" OMV is Atom N2800 based and has almost the same idle power draw. It is more efficient when its active, but has far less processing power for anything other than simple tasks.
