No, it was AMD's designation for their "advanced" 486, with support
for 4x multiplier and/or 40 MHz motherboard speed, both beyond
anything Intel offered for the 486.
[Intel was caught between a rock and a hard place -- if they tried
to trademark the "586" designation, their whole set of x86 trademarks
could unravel, which is why they left 586 un-trademarked and used the
name "Pentium" instead.]
