Whilst it is true indeed that POWER10 requires an opaque blob of firmware goo, Raptor was supposed to bring a follow-up to POWER9 that uses the Solid Silicon S1[0] instead of POWER10:
Raptor yesterday officially announced that we're not getting Power10 systems. The idea is we're going to be getting something better: the Solid Silicon S1. It's Power ISA 3.1 and fully compatible, but it's also a fully blob-free OpenPOWER successor to the POWER9, avoiding Power10's notorious binary firmware requirement for OMI RAM and I/O.
[…] the S1's specs, and he said it's a PCIe 5.0 DDR5 part running from the high 3GHz to low 4GHz clock range, with the exact frequency range to be determined. (OMI-based RAM not required!) The S1 is bi-endian, SMT-4 and will support at least two sockets with an 18-core option confirmed for certain and others to be evaluated. This compares very well with the Power10, which is also PCIe 5.0, also available as SMT-4 (though it has an SMT-8 option), and also clocks somewhere between 3.5GHz and 4GHz.
I have not heard of Solid Silicon before, and their website[1] does not reveal much other than indirectly ascertaining the non-laptop factor of the S1 SoC(?).
I would legit love to have a POWER10 laptop. No reason it couldn't be scaled down to laptop power profiles, though I have no idea who would provide a GPU for it.
and
something like the Altra Max M128
Would probably need to create a "hood", extender between the case and they keyboard to fit. and increase the fans a it </s>
