I'm afraid you're remembering incorrectly. The Pentium 100Mhz was released in 1994. The last Pentium released in 1999 was the PIII 800Mhz. There wasn't a 3GHz release until 2010.
And that's just clock speed. Compare any 2010 chip to something like a Ryzen 5800x and see how the benchmarks scores look.
