Version 2 efficiency looks insane. I consider getting a miner-only unit to test & review, however much I like my R909.
That one just gets about 50W/TH compared to Apollo 2's 30-35W/TH. Although it's nice to have something that pulls <100W at the wall and is basically silent. More on this soon..

It's definitely a big improvement from Version 1's 62.5W/TH in ECO mode and 66.66W/TH in Turbo mode!

Now I'm wondering which ASICs have been used here.. Tongue

Must be some quite modern stuff, considering the chips need some time to 'trickle down' to the home mining space.

A quick non-exhaustive list:

~100W/TH Bitmain S9
~50W/TH Bitmain S17
~35W/TH Bitmain S19 / Whatsminer M30S+
~30W/TH: Canaan Avalon A1346 / Whatsminer M50 / M53 / M56
~25W/TH: Canaan Avalon A1366 / A1446 / Bitmain S19k Pro
~20W/TH: Canaan Avalon A1466 / Bitmain S19XP / Whatsminer M60 / M63 / M66 / Bitmain T21
<20W/TH: WhatsMiner M60S / M63S / M66S / Bitmain S21

One theory would be that it uses S19 chips instead of the GekkoScience Compac F & R909's S17 chips. However FutureBit used to work with Bitfury in the past, maybe they partnered up again?

Yes, Apollo2 efficiency looks great, and I will definitely get one, to replace the existing Apollo1 which is currently being used to heat up my garden greenhouse slightly, during cold months. I control it by a script, to automatically switch between turned off, eco, balanced modes, depending on external temperature sensor. No turbo, because I noticed 6-pin connector on Apollo got burned down slightly and is now brown due to heat.. While second connector gets nothing, probably no current going through it, only one is getting hit. Probably some problem with Apollo current draw on PCB level... So I will limit the use to off, eco and balanced modes only on that unit.

And regarding efficiency. I've seen some crazy devices in my days with Bitcoin, have a look at my personal table, I've had all of these devices in my hands at one point

It's an amazing achievement that we can have 5 TH/s device in this small form factor.
