Not surprising at all. Everyone knows x86's days are numbered - at a certain point, there's not many microarchitectural more optimizations you can do, given all the cruft associated to the ISA, and you really need to reach for a cleaner design to improve performance. This is partially why Apple and Amazon switched to ARM. Intel knows this, so they don't have much choice to begin exploring alternative ISAs. SiFive is a leader in the RISC-V space, and so is the obvious choice for an aquihire.
- phkahler 5y agoIntel likes cruft. They keep adding extensions (sometimes stupid) to keep adding value for niche applications. That also forces AMD to try to keep up. RISC V is extensible and Intel would undoubtedly patent some extensions of their own, trying embrace/extend/patent on an otherwise open standard. Still might be cool as the base ISA is solid and the existing vector option is already superior. I'd love to see what Intel or AMD teams could do with it.
