Elmer - Finally found a press story on the Intel ISSCC paper.
Note that the 650 MHz testing was done with Tjunction at 25 C, so clearly forced cooling was required for the 0.25 micron part to reach 650 MHz.
The 0.18 micron should therefore reach 650 MHz with conventional cooling, if Intel's product development history proves consistent.

Intel takes Pentium III to 650 MHz

SAN FRANCISCO — Intel Corp. has successfully tested the Pentium III at speeds up to and including 650 MHz, according to a technical presentation made Monday (2/15) at the International Solid-State Circuits Conference here. In a paper titled "A 600-MHz IA-32 Microprocessor with Enhanced Data Streaming for Graphics and Video," Stephen Fischer, microarchitecture and microcode project leader for Intel's Pentium III, confirmed that the chip had been tested to the higher clock speed. The talk was a formal presentation of the architecture of the "Katmai" or Pentium III chip, which Intel will launch this Wednesday.
Fischer said the estimated clock speed had been tested on Intel's existing 0.25-micron manufacturing process. "And just wait until the 0.18-micron process," he added.
Other microprocessor presentations were made by Motorola Inc. describing a new 450-MHz PowerPC processor, and by Advanced Micro Devices who delivered two papers on separate aspects of their new chip, the forthcoming K7. Aside from more specific technical disclosures about each new chip, few additional product details were revealed.
