It seems to have been introduced the same year as Pentium 2 which had clock rates of 233-300 MHz. I don't know about the architectural differences at that time, but at least currently Intel processors smoke ARMs with same clock rate. The difference was probably a lot less pronounced at that time as the architectures were simpler.
