for BOINC you also have to consider the available applications too.

ARM apps usually have less optimizations, and will run slower real world vs mature/optimized x86 apps. so even if the hardware theoretically is comparable, and benchmarks indicate it's comparable, it will likely not have the same kind of throughput on BOINC.

However, it would have a LOT more cores/threads per system :)

not necessarily. EPYC Genoa

not necessarily. EPYC Genoa goes up to 192 threads per socket, and EPYC Bergamo goes up to 256 threads per socket.

Sorry, I was not clear.  A lot more threads vs. Pi5, Most cellphones, my Amazon Fire, etc.  Once you get up into the really high core/thread counts it gets way out of my price range :)

Here is another review of that bundle. It includes two new to me things.  The power supply are all 8 pins with an adapter to allow the 24 pin to handle the power on signal. And specific Noctua fan air cooler models. Apparently these CPU coolers are not yet on sale.

Last time I checked on this bundle on NewEgg they were now accepting backorders.

Respectfully.

So is that setup as 80 or 128 different OS's or one OS with all those cores or both or even a cmbination of the two? If you can't clone an OS that would seem to be a pain in the neck to setup 80 or 128 different OS's!!

I saw one guy with 32 cpu cores on their pc that they setup with 32 OS's, one for each cpu core, I don't know the benefit but there must be one for them. Maybe an exercise in 'can I if I want too' I don't know.

You are starting to see

You are starting to see motherboards supporting the new ATX12VO power specification which does away with the motherboard 24 pin connector and replaces it with just a 10 pin connector and a couple more ATX12V2 8 pin connectors.

There is no more +3.3V and +5V voltages in the power supply specification.  All those voltages are generated onboard the motherboard with bucking down the 12V input voltage.

Makes for simpler but more complex cabling since you will have to have SATA power connectors on the motherboard for example and not just the data cables for those devices.

From my POV this is just like the regular AMD and Intel systems.  You have one system but lots of horses (err cores/threads) under a single OS. 

I can imagine setting up Virtual Machines on this MB.  But I can't imagine running 32 of them :)

Are there adapters to help the older PSU work with the newer specifications?

That's what I was thinking as well.

Unlikely.  I have only seen one example of the new power supply meant for DIY.  It is meant to be paired with a ATX12VO motherboard.

The place where you will see the increased usage of this new standard will be with the OEMS like INTEL HP and DELL
