The Pentium 2, from what I can tell, was produced on .35, .28, and .25 micron. You're right, I just looked it up, and Klamath was .35. Deschutes was .25, but I'm fairly sure that a number were produced on a .28 micron, at some point.
sandpile is a site run by a guy who's job used to be hunting down bugs in the Crusoe chips, and he damned well knows his stuff....and yet, his site states that Klamath was .28
Guess everyone is falliable.
But yes, the Klamath P2s @ 233mhz were nice 'n warm at ~35 watts. The 300mhz Klamath P2s were at a whopping 43watts (yet no one ever dares believe that Intel chips were hot, even "back in the day"....but I digress).
