It is a software problem, and it could have been solved with software. It was simply assumed a priori that it couldn't be solved, so no one bothered to try.
- wmf 4y agoOr they talked to Microsoft who said it would take years to add that feature.
- undersuit 4y agoOr they talked with Microsoft who refused to add it to anything but Windows 11. Or maybe they can't handle it because of some difficiency in their Linux ports. The thing is it is possible and Intel knew for years that the E-cores wouldn't have AVX512.
- moonchild 4y agoLet it take years, then. Leaving it disabled in the bios by default is one thing, and a rather reasonable one at that. Fusing it off is quite another.
- Twirrim 4y agoThis isn't a new decision, it came out a few years ago that you'd end up with disparate instruction sets between the main and efficiency cores, and they got warned it would be a problem. Their disabling of the instructions to avoid it came about as a response. Both Microsoft and Linux devs warned them about the difficulties it'd present.
