Tejas and Jayhawk

This was already the case with Prescott and its mediocre performance increase over Northwood despite higher clock speeds, not to mention heavy competition from Advanced Micro Devices with their Athlon 64.

Tejas went even further ahead with this paradigm, with Intel targeting 10 GHz clock speeds by 2011 trying to fulfill the prediction made by Andrew Grove in his keynote speech at the 1996 COMDEX/Fall.

With respect to desktop processors, Intel's development efforts shifted to the Pentium M microarchitecture (itself a derivative of the P6 microarchitecture last used in the Pentium III) used in the Centrino notebook platform, which offered greatly improved performance per watt compared to Prescott and other NetBurst designs.

There was also to be a dual core version of Tejas called Cedarmill (or Cedar Mill depending on the source).

This Cedarmill should not be confused with the 65 nm Cedar Mill-based Pentium 4, which appears to be what the codename was recycled for.

However, it's likely that Tejas wouldn't have had linear performance scaling, as it would on average have executed fewer instructions per clock cycle due to more pipeline bubbles from branch mispredicts and data cache misses.
