They've always been a mess of microcode translation and other bullshittery. All 53.999999999999999999999999999998 generations.

microcode.... turns the processor's control logic into a programming task instead of a difficult logic design task
Microcode also permits complex instructions and a large instruction set to be implemented without making the processor more complex
it is generally easier to fix a bug in microcode than in circuit logic.
Nah bro we'll just run with the bugs and hope no one notices.
Sounds like you work for Intel!
I especially love it when Intel bugs appear after running fine for a while and later brick the device! No alerts from Intel!
