My reading is that you can now make a simple CPU compatible with the power ISA which gets you compatibility with power ports like gcc and the linux kernel.
But to be competitive with Epyc, Xeon, and the Power 9 you'd have to spend a pretty huge amount of R&D. It does sound like there's some IP related to the memory controller which is available, but there's much required for a high end CPU that is not available.
- justinjlynn 7y agoWe've a proven ISA with performant implementations, of both silicon and compilers, now, and now we as a community can invest in that R&D together under open terms. It's a big step forward.
