When they came out with the POWER9 systems originally the price to performance wasn’t that bad. It’s been a while since then. But also they seem to have known their market so priced it to hopefully be a sustainable business to recover the engineering costs.
Losing money to enter a market requires a lot of money. This generally only happens in a big company, which is the current market where no one cares about being open or hackable, or VC funding, which has historically been anti-open and anti-hackable in the long run. VC money has made first or second generation products which are in that direction but longer term has not had a great record.
I think Raptor’s plan was/is the right one but the market of consumers who will pay extra to get that openness is quite small.
Framework is close. They’ve had a LOT of VC money.
