None of which were available in November 1993. And having used the
R4600 quite a bit in 1996, I'm fairly sure that it did *not* have
speculative execution.
The Pentium can do speculative execution as well,
The Pentium was superscalar, but did not do speculative execution.
SE was introduced with the Pentium Pro, which was not introduced until
1995.
I suspect that there were some processors with speculative execution
before November 1993, but not microprocessors.
I'm not convinced that you've earned your three extra geek points
today, sorry.
