The Pentium 4 is delayed till the end of November. Due to a relatively minor chipset issue, Intel has had to rev ICH2 to fix compatibility problems. At least this means there should not be any CPU shortages when the chip does ship. Intel will have an extra month to produce more Pentium 4s. We also doubt this will hold up the long term prospects of the chip. Intel will still have the month to work on boosting the clock speed and improve their production. We expect extremely highly clocked Pentium 4 processors to come next year. 1.4GHz and 1.5GHz are merely the start.
If you don't know the details of the Pentium 4, we strongly recommend you read our Pentium 4 Unveiled article here. We have more information to add in our Intel Developer Forum 2000 Show Report. And we have even more information in our Pentium 4 and Timna Update article.
The Pentium III 1.13GHz' return has been pushed out all the way to Q2 2001. The Pentium 4 will take up the high-end where the 1.13GHz Pentium III would otherwise have resided. Tualatin, the .13 micron Pentium III, will come in Q3 2001 at 1.26GHz.
