Crunching farm considerations

[Dirk Broer]

TDP be what is may be, but while comparing TDP values between Intel and AMD CPUs can't reliably be done due to difference in definition used, TDP values between AMD cpu's are at least comparable.

What does AMD offer at the moment?
My 'set and forget' x86-architecture section presently runs on the AM1 platform, three AMD Athlon 5350 quad-core APUs (SOCs really) with a TDP of 25 Watt, so 6.25 Watt TDP per core/thread,
and one Gemini Lake platform Intel J5005 quad-core SOC with a TDP of 10 Watt, so 2.5 Watt TDP per core/thread. All four are iTX systems.
Must they be replaced with something newer? If yes, by what?

At the moment the Ryzen 3 2400GE looks like an ideal candidate to replace my aging Athlon 5350's, but I have yet to encounter one in the wild.
The 'set and forget' section only needs a SSD and RAM sticks, so a board with an A320 chipset should be enough. iTX A320 boards do exist (Asrock),
but here too I have yet to encounter one in the wild. The local agent (Asrock Europe) does not stock them, AFAIK.
A MSI B450 iTX board might be a good alternative though -and a well-ventilated iTX case to provide the much needed VRM cooling when you decide
to let go of the -top-down blowing- stock cooler, in favour of a huge cooling tower. Fortunately I have such a case.
