Youssie, re:<why do they have to use .25um processing to accomplish this>

Intel could only reach 266 and 300 MHz by upping the transistor current, and hence, the power dissipation to unacceptably high levels. They solved the thermal problem with the proprietary thermal brick, which can dissipate the 30-40 watts that a Pentium II consumes. Without the thermal brick, the top speed of Pentium II would have been thermal-limited at 200 MHz, not even 233.

Thermal brick was not an option for AMD or Cyrix. With less than 5% market share, no one would have made mobo's for a proprietary solution. So, in essence, we find again that Intel used their monopoly share to advantage here.

Fortunately, the thermal brick is apparently unnecessary at 400 MHz and below when the 0.25&#181; process is used.
