In what year did we see the first 1000mhz CPU?

2000- it be the intel pentium 3
i cant remember the year but i know i used to have an athlon 1000mhzwith a voodoo 5500 graphics card
assuming you're chitchat about x86 CPUs later see above, though if memory serves an overclocked Athlon did it first
I remember that at 1994 I was a freshman and I have a 66MHZ CPU and at the same year in attendance were computers going at 100MHZ.
