Core Voltage: The Phenom Requires Just 1.20 Volts

The Phenom X3 8750 with 2.40 GHz provided by AMD uses a core voltage of just 1.20 volts. The missing processor core is obvious, the Phenom X4 9850 or 9750 with four cores requires a considerably higher voltage of 1.30 volts.

The Phenom X3 8750 manages with 1.20 volts.

The Phenom X4 9850 requires 0.10 volts more.

In comparison: The older Phenom X4 9600 with B2 stepping has a core voltage of 1.250 volts.

The Phenom X4 9600 needs 1.25 volts.

If the Phenom X3 is switched to the Cool’n’Quiet energy saving mode, the voltage, as with the Phenom X4 models, drops to 1.050 volts.
