M1L Notes:

The Absolute Maximum Voltages are the highest voltages the chips can take for a short period of time. Extended use of the processor at or near these voltages will cause permanent damage to the chip. Reliable operation of the chip outside its nominal voltage range is not guaranteed.
Typical amperages were measured at nominal voltages.
Maximum amperages were measured at maximum voltages.
The maximum power dissipation numbers were taken from the IBM (not Cyrix) datasheets. Cyrix does not have wattage numbers for the 6x86L chips. Maximum power dissipation was measured at 3.3v (this puts the core at absolute maximum voltage) while running Landmark Speed200 v2.0.
IBM states that typical power dissipation numbers are about 15% less than the maximum power dissipation.

M2 Notes:

The Absolute Maximum Voltages are the highest voltages the chips can take for a short period of time. Extended use of the processor at or near these voltages will cause permanent damage to the chip. Reliable operation of the chip outside its nominal voltage range is not guaranteed.
Maximum amperages were determined using the worst-case instruction mix at maximum voltages.
Maximum power dissipation was determined using the worst-case instruction mix at typical voltages.

C6 Notes:

The Absolute Maximum Voltage is the highest voltage the chips can take for a short period of time. Extended use of the processor at or near these voltages will cause permanent damage to the chip. Reliable operation of the chip outside its nominal voltage range is not guaranteed.

Mobile VRT P54C Notes:

Voltage Reduction Technology is a lower power split-plane (dual-rail) voltage used in mobile Pentium chips to reduce power consumption and prolong battery life. VRT is specifically 2.9v/3.3v or 3.1v/3.3v. The 2.8v/3.3v split-plane voltage on the Pentium w/ MMX processor is not considered VRT. There is also a single-plane 3.1v mobile chip that is not VRT, even though it is a mobile chip.
The single-plane 3.1v mobile chips (Q0882, Q0906, SY046, SY027, SY028, and SY043) are not listed here (or anywhere for that matter).
The Absolute Maximum Voltages are the highest voltages the chips can take for a short period of time. Extended use of the processor at or near these voltages will cause permanent damage to the chip. Reliable operation of the chip outside its nominal voltage range is not guaranteed.
Maximum amperages were measured at maximum Vcc and under worst-case instruction mix.
Typical power dissipation was measured at normal operating voltages and under normal system operation (running typical applications).
Maximum power dissipation was measured at normal operating voltages and under worst-case instruction mix.
