ICOMP INDEX from 2004

Several people express confusion about why one cpu is better or worse than another. The readers digest version is that Pentium3's are generally better than Pentium2's or Celeron's with the following exceptions. The Tualatin Celeron is Better that the Regular Pentium3. Tualatin Pentium3's are 133Mhz FSB but since GX1's only Run at 100Mhz FSB then they arent an Issue. The GX150 might make a Better candidate for the Pentium3 Tualatins.

Several Years Ago I made an ICOMP list by Compiling the various Lists available on the INTEL site.

It is listed below as a reference for those who are looking to gauge speed.

Estimated Icomp 3.0 Processor Speed = 2.59 Times ICOMP2 LOL!!!
Multiply ICOMP2.0 * 10 and get ICOMP 1.0
AKA Pentium 120 has ICOMP1 of 1000 and ICOMP2 of 100.
