NaS, I did not say no to a 1.33GHz Pentium III. I said there were no 1.3GHz Pentium III varieties, and that was applicable to your argument at the time. Furthermore, since the 1.33GHz Pentium III shipped after the launch of the 1.5GHz Willamette, you have no argument that Pentium III outperformed Pentium 4 at the time of launch. The fastest Pentium III in the same time frame ran at 1.13GHz, but that was recalled. Tualatin, the .13u core that supported >1GHz frequencies, launched in April or May, 2001 - six months after the Pentium 4 launch - and faster Pentium 4 chips were available by that time, all on .18u and offering higher performance.

I originally stated something to the effect that there is a PIII core that runs faster (not clock speed,
just application performance in the avg joe mindframe) than the P4 at the initial speed grades (1.3 to
1.5 GHz).

The PIII shipped as fast as 1.4 GHz. But all PIII faster than 1.0 GHz were Tualatin PIIIs, i.e.
manufactured in a 130 nm process. The 1.3 GHz P4 was made in 180 nm process and
no 180 nm PIII ran faster than 1.0 GHz (there was a 1.133 GHz PIII but it was recalled).

If you want to compare without regard to process you can show just about anything. At the
end of the month you will see 130 nm IPF processors that clock faster than a 1.3 GHz P4.
