AMD entered the high-performance computing marketplace, a segment traditionally controlled by Intel, with the Athlon K7 500 processor. Built by a .25-micron fabrication process, the original K7 offers only modest overclocking scalability compared to later designs. Maximum scalability for the entire K7 series falls in the 750 to 850 MHz range, with the occasional unit offering slightly improved potential with extreme cooling.
The K7's power demand always attracts attention. Though it runs at 500 MHz, this unit demands 42 watts at peak operation. Cooling is thus a big concern. The factory heatsink is well designed, but any attempts at overclocking should include the use of a quality aftermarket forced-air heatsink. Average scalability for this speed grade falls in the 600 to 650 MHz range.
