Actually, processors DON'T have a specific voltage by design, one is arbitrarily applied by the manufacturer. Instead, they have a voltage range. Prior to the release of special CPU's for laptops, many standard processors were specified for laptops because they could be used at lower voltage. In fact, many of these laptop chips were underclocked desktop chips, they ran them slower so they could reduce the heat and power consumption. One method of reducing heat and power consumption is to reduce voltage.
This can easily be seen by Intel's voltage of the Celeron 566 at 1.50v, and the PIII 750 at 1.65v, both on the exact same revision of the exact same core. Later PIII's came with the voltage at 1.75v, as Intel attempted to standardize the voltage across the entire line of PIII's. Slightly updated core, same die process, didn't really need 1.75v except at the higher speeds.
Manufacturers will often specify an upper limit for voltage, but sometimes even these aren't perfect.
