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.

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.
  • The Winchip-2A 233 runs at 233MHz on a 66MHz bus; the 266 runs at 233MHz on a 100MHz bus (it uses an unusual 2.33x multiplier).
  • The Winchip-2B 200 runs at 200MHz on a 66MHz bus; the 233 runs at 200MHz on a 100MHz bus.
  • The Winchip-3 CPUs run at 233/66, 233/100 (2.33x multiplier), 266/66, 250/100, and 266/100 (2.66x multiplier).
  • The mobile Winchip-3 CPUs run at 200/66, 233/66, 233/100 (2.33x multiplier), and 250/100.

i386 Notes:

  • The 386 processor power numbers come from the embedded processor notes, and not from the original datasheets. The actual numbers for the chips sold in the retail market may vary slightly, but not by very much.
  • Typical power dissipation was average value measured at typical voltage running typical applications, but is highly dependent on specific system configuration.
  • Maximum active power dissipation is measured at typical voltages and worst-case instruction mix.
  • The 386SX has a 16-bit external bus. The 386DX has a 32-bit external bus.

  • All surface-mounted (QFP) Intel 486 chips run at 3.3 volts. All socketed (168-pin PGA) Intel 486 chips run at 5 volts (except for the i486DX4 chips).

  • Typical power dissipation was measured at normal operating voltages running typical applications.
  • Maximum power dissipation was measured at normal operating voltages and under worst-case applications mix.
  • There is some variance among the P5 chips regarding voltage range and maximum case temperature. This can vary from sSpec to sSpec. See the Pentium 60/66 Specification Update for details.

  • 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.
  • Maximum amperages for the chips were measured at 3.6v and worst-case instruction mix.
  • Typical power dissipation was measured at 3.3v for the 75, 90, 100, 120, 133, and 150MHz chips; 3.52v for the VRE 120MHz chip; and 3.5v for the 166 and 200MHz chips. These chips were running typical applications.
  • Maximum power dissipation was measured at 3.3v for the 75, 90, 100, 120, 133, and 150MHz chips; 3.52v for the VRE 120MHz chip; and 3.5v for the 166 and 200MHz chips. These chips were running a worst-case instruction mix.
  • These processors come in various voltage configurations:
    • STD (3.3v) - 3.135v ~ 3.465v - Standard Voltage.
    • VR (3.38v) - 3.300v ~ 3.465v - Voltage Regulated.
    • VRE (3.52v) - 3.450v ~ 3.600v - (B-step) Voltage Regulated Extended.
    • VRE (3.5v) - 3.400v ~ 3.600v - (C2 step and later) Voltage Regulated Extended.

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.
