John,
Just when I thought it was safe to go back in the water, I found the following on page 104 of the Jan 20 issue of PC Magazine:
"Though slightly faster than the current version of Tillamook (233 Mhz), the mobile K6, manufactured on AMD's 0.25-micron process, is neither as small nor as cool. With a 2.1 volt core and 3.3 volt I/O (Tillamook uses a 1.8/2.5 volt design), the chip's 266 MHz version has a power dissipation of roughly 8 watts, alevel similar to that of past mobile Pentiums but well above the 233 MHz Tillamook chip's 3.9 watts.
In informal testing, PC Labs found the mobile K6's CPUmark32 scores to be above the average for the tested Tillamook, as would be expected at the faster clock speed. With its original drivers, however, it couldn't complete our Business Winstone 98 tests. With replaced drivers, the unit had a BusinessWinstone 98 score lower than those of most 233 MHz Tillamook units. Repeated test runs resulted in decreasing scores caused by CPU slowdowns, which may indicate heat problems."
Now, maybe this thread has already discussed/dismissed this (as the next issue of PC Mag is already out), but it's news to me and scares the hell out of me.
