RISC-V and MIPS are the only semi-modern architectures I know of that can be implemented with 100% open hardware down to the schematics of every single component on the mainboard/CPU/etc.
And the main problem with those is performance. Even the fastest RISC-V board currently available (which is also proprietary) is still twice as slow as a Raspberry Pi 3.

- oneplane 5y agoYou can use ARM but it will only be open to the people paying for the NDA.
- derefr 5y agoIs that “just” a matter of the process node used to fab them, though? What would the power profile of a RISC-V taped out for TSMC’s 5nm process look like?
- londons_explore 5y agoThey're still small slow processors. Sure, it's possible to design a big fast RISC-V processor to rival the M1, but nobody has done it yet.
- derefr 5y agoWouldn't the energy efficiency of a (much) smaller process node enable you to greatly overclock the chip (compared to now where it's thermally limited to a low clock), though? And/or just pack many of them per die?
