All of the information contained on this page came directly from the various datasheets provided online. Links to the datasheets are provided at the bottom of the page. Since not all of the pertinent information is clearly spelled out in the datasheets, some of the numbers were calculated using formulas found in the datasheets. Where these calculations are used is clearly marked and the formulas used are also provided.

Please note that the 'Max. Case Temp.' is the maximum temperature allowable as measured on the exterior of the processor package in the middle directly above the chip die (under the heat sink). It is not the maximum internal ambient temperature of the system enclosure. The term 'case' refers to the processor's package, not the system case. For that, AMD suggests:

"The environmental specifications on most systems guarantee operation for external ambients up to 35C. Most PC chassis/system boxes result in a 10C increase in temperature over the external ambient temperature. In general, this means the thermal solution should be designed to allow an internal ambient (TA) of 45C."
The other chips follow this rule similarly. The Pentium II chip, for example, allows a typical 35C~40C ambient temperature and a 45C upper ambient temperature limit. Although the internal ambient temperature of the system enclosure isn't nearly as important as the temperature of the processor package closest to the CPU die. Intel states:
 
"An ambient temperature is not specified for the Pentium II processor. The only restriction is that Tcover (cover temperature) and Tplate (thermal plate temperature) be met."
I added the Pentium II temperature Tplate, which is measured under the heatsink directly above the processor core. Tcover, on the other hand, is the measurement on the SEC cartridge on the opposite side from the heatsink.

x86 Notes:

  • Maximum power dissipation was calculated from Pmax=(Tcase-Tambient)/(Oja-Ojc). Where Oja (theta) is junction-to-ambient thermal resistance and Ojc is junction-to-case thermal resistance in C/W. Tambient was measured at 3.3V and 0.931A.

K5 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.
  • Maximum power dissipation was calculated from Pmax=(Tcase-Tambient)/Oca. Where Oca (theta) is case-to-ambient thermal resistance in C/W. Tambient was measured at typical voltages and maximum amperages.

K6 Notes:

  • The 2.2v CORE K6 chip is the .25 Model 7 K6.
  • Unlike most of the other chips listed here, the AMD K6, K6-2, and K6-III do not list an Absolute Maximum Voltage. Instead, they have a recommended upper limit for reliable operation of 3.5v/4.0v (2.5v/3.6v for Model 7 and Model 8; 2.6v/3.6v for Model 9). However, operation of the chip outside its nominal voltage range will still void the warranty.
  • Maximum amperages for the 166MHz and 200MHz chips were measured at 3.045v/3.6v.
  • Maximum amperages for the 233MHz (3.2v version) chip were measured at 3.3v/3.6v.
  • Maximum amperages for the 233MHz (3.3v version) chip were measured at 3.4v/3.6v.
  • Maximum amperages for Model 7 and Model 8 chips were measured at 2.3v/3.6v.
  • Maximum amperages for Model 9 chip were measured at 2.5v/3.6v.
  • Typical power dissipation was measured at normal operating voltages and under normal system operation (typical instruction sequences).
  • Maximum power dissipation was measured at normal operating voltages and under worst-case instruction sequences.
  • The specs listed in the datasheet for the 533MHz K6-2 part are exactly the same as the 500MHz part.

Mobile K6 Notes:

  • The mobile 433MHz K6-2-P and K6-III-P run at a very unusual bus speed of 96.2MHz with a 4.5x multiplier.
  • Unlike most of the other chips listed here, the AMD K6, K6-2, and K6-III do not list an Absolute Maximum Voltage. Instead, they have a recommended upper limit for reliable operation of 2.5v/3.6v. However, operation of the chip outside its nominal voltage range will still void the warranty.
  • Maximum amperages for the mobile K6 and K6-2 were measured at each chip's maximum voltage.
  • Typical power dissipation was measured at normal operating voltages and under normal system operation (typical instruction sequences).
  • Maximum power dissipation was measured at normal operating voltages and under worst-case instruction sequences.
  • All values apply to both the PGA (pin grid array) and BGA (ball grid array) mobile chips. PGA chips come with the 'ANZ' designation; BGA come with 'BNZ'. The mobile K6-2-P and K6-III-P only come in 321-pin PGA form.
  • Maximum amperages for the mobile K6-2-P and K6-III are the maximum a power supply will have to deliver to the chip.
  • Application Power (listed as Typical Power Dissipation in the above chart) for the mobile K6-2-P, K6-III-P, K6-2+, and K6-III+ is the average power dissipated when executing instructions sequences under normal system operation (2.2v/3.3v or 2.0v/3.3v).
  • Design Power (listed as Max Power Dissipation in the above chart) for the mobile K6-2-P, K6-III-P, K6-2+, and K6-III+ is the maximum sustained power dissipated when executing instructions sequences under normal system operation (2.2v/3.3v or 2.0v/3.3v).

Athlon Notes:

  • For 3.3V SRAMs, the voltage upper limit is 4.0V. For 2.5V SRAMs, the upper limit is 3.0V.
  • The old Voltage Regulation App Note for Athlon Classic chips (early K7) indicated that motherboards should be designed with a maximum 35A current draw in mind to prepare for a "next generation of processors from AMD". The App Note went on to give examples of a theoretical chip running at 1.6V and drawing 30 amps as well as one at the design max of 35 amps.
  • Power numbers (typical and max wattage) include the 512KB L2 cache running at max case current conditions.
  • The K7 is made on a 0.25 process; the K75 is made on a 0.18 process.
  • The Core Voltage Upper Limit on the Athlon has been increased from 1.9V (0.3v over nominal) to 2.1V (0.5v over nominal) for both the K7 (model 1) and K75 (model 2) chips.
  • Note that the wattage and amperage numbers for all model 2 (K75) Athlons has been revised. Both dropped.
  • With the addition of the 1.2GHz Athlon and 800MHz Duron chips, voltage, wattage, and amperage numbers for the PGA Athlon and Duron have changed (they're now higher). I'm not sure if this is due to a core stepping change or is just a re-evaluation of the chip's electricals by AMD. Both old and new chip specs are still listed.
  • Athlons running on a 133MHz bus but at the same core speed as their 100MHz counterparts have the same thermal specifications.
  • The 550MHz Duron and 650MHz Thunderbird chips do not exist. Apparently a few 700MHz Thunderbirds escaped from AMD, but the chip was never officially launched.
  • Max Case Temp for the PGA Athlons and Durons is really Max Die Temp.
  • For the Palomino Athlons and Morgan Durons the Maximum Power Dissipation is "maximum sustained power dissipated while executing publicly-available software or instruction sequences under normal system operation at nominal VCC_CORE. Thermal solutions must monitor the processor temperature to prevent the processor from exceeding its maximum die temperature."
  • Note that typical wattage numbers for the Morgan Duron have increased (Jan 2002).

Mobile Duron/Athlon 4 Notes:

  • Maximum Power Dissipation is "maximum sustained power dissipated while executing publicly-available software or instruction sequences under normal system operation at nominal VCC_CORE."
  • The "Morgan" Duron and Athlon 4 can step down it's core speed (down 300MHz, depending on the BIOS implementation) along with its core voltage (down to 1.2v) in order to save power in notebook computers. See the datasheet for more information.
  • Amperage draw and power dissipation numbers have been revised upwards for the Morgan Duron processor (Dec 2001).

M1 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.
  • Typical amperage was measured at 3.3v.
  • Maximum amperage was measured at 3.3v.
