Master baker tier. Every paragraph earns its place on the tray.
Summary
The article discusses various CPU hardware bugs and design flaws found in vendor CPUs, focusing on specific examples like Intel's misspelled CPUIDs and other undocumented or poorly engineered features. The author shares observations about these mistakes that haven't been widely discussed, providing evidence and analysis to make these issues more publicly known.

· 3 pulledSince I've never seen these widely discussed, here's some discussion and links to supporting evidence to make them more widely known, since I think they're interesting.
This seems embarrassing for an organization of Intel's size, but probably not a big deal in practice.
Catherine (Whitequark)'s recent observations on poorly-engineered firmware reminded me of a few mistakes I've seen in vendors' CPUs; some unimportant and others surprisingly bad.
