And don't forget the famous Pentium division bug in the 1990s:

The fact that the famous Pentium division bug is still being talked about speaks highly of processors as bug-free software.
I never said they were all bug-free. I am aware that there have been some problems over the years, but the track record seems much better with CPUs than with most things having what could be called advanced programming.
Having a game over user to kernel exploit available for who knows how long is not my idea of anywhere near bug-free.
And who knows what happens or what bugs are fixed when intel/amd push new firmware to the chip.
