Intel optimizes power for mobile Prescott stepping

Intel is apparently working on a new stepping of its mobile Prescott core that contains "power optimizations to enable speed enhancements." The new stepping isn't scheduled for release until October, so Intel may be adding 64-bit extensions to the mix as well.

Given Prescott's toasty reputation, I'm a little surprised that Intel hasn't brought SpeedStep or other power saving technologies to the desktop. AMD already has Cool'n'Quiet, which nicely lowers Athlon 64 clock speeds at idle. Prescott could use something similar.
