Intel Celeron 566

Unlike the Celeron at 500MHz or 533MHz this one has been made with the so called 'Coppermine' core. It's made on a 180nm manufacturing process and because of this it can run at higher clock frequencies with less voltage.

The Coppermine CPU's on socket 370 are also FC-PGA rather than PGA. FC stands for Flip Chipped and PGA for Pin Grid Array. Essentially both are housed in a plastic cpu package but the Coppermine has the chip backwards to allow for better cooling and easier connection with the pins in the plastic housing. You can easily spot the difference by it's color: the packaging of FC-PGA Celeron's is green. The older regular versions are black.
