This thread isn't about OpenPOWER, but as someone typing this reply on a Raptor Talos II with Fedora 34 (and with a Blackbird in the home theatre), it actually is a more open system than the M1 or x86_64 that is in the same performance ballpark. If you want performance per watt, well, the M1 will spank everything right now, but I don't feel like this machine is at all underpowered (which, sadly, is still the case for RISC-V). I'm no Stallmanesque ideologue; I'm attracted to the M1 because of its low power usage and I've used Macs for years and for my next mobile system I may end up picking up an Air. But as a desktop workstation POWER9 systems like this really are more open and credible alternatives, and I felt it was well worth the price.
