1. To get wattage of CPU:
new=(new FSB/spec FSB)*((new Vcore/spec Vcore)^2)*spec watts
C/W Ratio:
Delta = CPU temp - Ambient Temp
C/W = Delta / CPU Watts
CPU temp= C/W x CPU Watts + Ambient Temp
Pnew = Pspec * (Fnew/Fspec)*(Vnew/Vspec)^2
P = Power in watts
F = Frequency in MHz
V = Voltage
new = P, F and V at the new settings
spec = Intel’s published specifications for the CPU in question
For the Celeron 366, let’s assume we are hitting 550 MHz at 2.3 volts. Plugging these numbers
into the equation:
Pnew = 21.7 * (550/360) * (2.3/2.0)^2
Pnew = 21.7 * 1.50 * 1.32 = 43.0 watts
