There is also OpenPOWER (under the Linux foundation) which I assume is also good? Or is RISC-V stictly better than it?

- panick21_ 4y agoOpenPOWER simply wasn't open, it was simply marketing. Only years after RISC-V started to grow did they change their licensing. RISC-V is more modular and and by now has far more support behind it.
- classichasclass 4y agoOpenPOWER is also an open, royalty-free ISA. You're right that PowerPC and Power ISA didn't start open, but they weren't called OpenPOWER.
- panick21_ 4y agoEven when it was called OpenPOWER it was not as open as RISC-V. Its only much later that it became so.
- classichasclass 4y agoI have several OpenPOWER systems, including the POWER9 I use as my usual desktop. Besides IBM and other server manufacturers like Tyan and Wistron, you can get them as Raptor workstations and servers. If you want an OpenPOWER design to play with, look at Microwatt ( https://github.com/antonblanchard/microwatt https://github.com/antonblanchard/microwatt ) which is complete enough to boot Linux.
