General CPU Discussion / Re: The point about Power 10 currently

Well, I do not believe that anything about that POWER10 module precludes being used in a home environment, just that IBM would have to sell it on the OpenPOWER market and Raptor or someone would have to build a motherboard to support it. I think this is the HotChips presentation?

Those external-cable connectors would be for the PowerAXON interfaces which let the processor scale up to lots of sockets. The memory and PCI interfaces wouldn't use such cables. Much like all the POWER9 processors have lots of socket-to-socket I/O that aren't used by the Raptor systems, a bare-bones POWER10 system could ignore all the cabled interfaces and just use the ones that connect thru the socket.
Of course, the likely answer is that the cost of such a design is still prohibitive, since it presumably has to use the fancy buffered memory DIMMs:

It isn't clear to me how the spring mid-range and low-end announcements will be more amenable to a consumer-focused POWER10 system, but here's to hoping that the landscape changes come 2022! I would love to buy a POWER10 system!!
