The interesting thing is that they have some details about the cancelled Tejas in this article:

"Fisher has been on Intel's payroll for quite some time: he worked on the 486 cpu, the definition of mmx and sse instructions, and also on the Pentium III. The previous product that Fisher worked on was codenamed 'Tejas'. It was to be a 65nm version of the Pentium 4 with an extremely long pipeline of 40 to 50 steps, in order to achieve clock speeds of 7GHz or even higher.

Work on Tejas had progressed considerably when it dawned on Intel, back in 2004, that there was no future for the Pentium 4 architecture. The team had just achieved the 'tape out'-point when news came in that the project had been canceled. The 'tape', which was meant to be sent to the factory to make the first physical version of the chip, is now lying in a safe gathering dust."

Someone needs to tape that thing out and put it on ebay along w/ a tank of liquid helium.
 
w00t! Cryogenic Tejas.

Sad thing is, at 10Ghz it probably still would get spanked by a 4Ghz dual-core Penryn ;)
