Scumbria, Re: "Designers rarely worry about power or heat in the first implementation of this type of design. K7, Alpha, Willy and Merced provide good evidence of this." Would size also be one to add to this list? Since the majority of the MPU lifetime will be on the next generation process. PT

Designers rarely worry about power or heat in the first implementation of this type of design But couldn't this be significant? Power consumption keeps going up, but the thermal conductivity of the chip (as far as I know) stays a constant. Willy is a chip that will (according to Paul DeMone) consume twice the power at 1.5 GHz as a P3 at 1GHz. Since parts of the chip run a different speeds, this power production might be very concentrated on some parts of the chip. How can this be ignored in the design stage? Also, wasn't Merced was designed to run faster than 700MHz?
