Processor Electrical Specifications

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 heatsink). 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 35°C. Most PC chassis/system boxes result in a 10°C increase in temperature over the external ambient temperature. In general, this means the thermal solution should be designed to allow an internal ambient (T_A) of 45°C."

The other chips follow this rule similarly. The Pentium II chip, for example, allows a typical 35°C~40°C ambient temperature and a 45°C 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.

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 P_max=(T_case-T_ambient)/O_ca. Where O_ca (theta) is case-to-ambient thermal resistance in °C/W. T_ambient was measured at typical voltages and maximum amperages.

K6 Notes:

The 2.2v CORE K6 chip is the .25µ 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 0.25µ process; the K75 is made on a 0.18µ 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.

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.

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.

Mobile Tillamook Notes:

Tillamook is the .25µ mobile version of the Pentium w/ MMX.
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 at Tcase=0°C.
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.

P54CTB 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 amperages for the chips were measured at 3.465v, case at 10°C, and with worst-case instruction mix.
The 200MHz Pentium OverDrive w/ MMX requires a Socket 7 motherboard to handle its requirements for 5 amps of current, 17 watts of power dissipation, and 1.75" of overhead clearance.

P6 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 amperages were measured at maximum nominal voltages.
Typical power dissipation was not actually tested, but reflect the maximum power you would expect to see when running high power applications on most devices.
Maximum power dissipation was measured at normal operating voltages.
Note that the Pentium Pro 200 w/ 1MB L2 cache will run at either 3.2v or 3.3v nominal voltage. In order to run the chip at 3.2 volts, the VID (voltage identification) from the processor must be ignored by the motherboard. This chip also puts off more heat than any other Pentium Pro chip. So it comes in an altered package that has an exceptionally flat surface where the heatsink is attached.

PII 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 normal voltages while running Winstone96 under Windows95.
Maximum amperages were measured at max core voltage, at 95° C, and under maximum signal loading conditions.
Maximum power dissipation was measured at 100% processor core and 100% L2 cache power.
Maximum plate temperature is measured under the heatsink directly above the center of the processor core.
Maximum cover temperature is measured at the three known hot spots on the SEC cartridge on the opposite side from the heatsink. See Figure 17 in the Pentium II Processor Thermal Design Guidelines for the locations of the hot spots.
The temperature of the ambient air entering the fan on the boxed Pentium II 350, 400, or 450 chip must be below 45°C.
The Pentium II Deschutes had a 5% die shrink around the end of August 1998 starting with the 6-5-2 step core chips.

PII/PIII SECC2/FC-PGA/FC-PGA2 Notes:

The thermal specifications for the SECC2 in both PLGA and OLGA configurations are at nominal core Vcc and nominal Vcc for the L2 cache.
Processor power includes power dissipated by the processor core, L2 cache, and GTL+ bus termination, although the max for each does not occur simultaneously.
Processors in the SECC2 package do not have an extended thermal plate.
Processors using the PLGA core have a maximum case temperature. OLGA packaged chips, however, have a junction temperature that is measured with the on-Die thermal diode. How to measure each is specified in AP-586 Pentium II Processor Thermal Design Guidelines.
TDP is listed as 'Max Power Dissipation' for some of the chips in this chart. "Thermal Design Power (TDP) represents the maximum amount of power the thermal solution is required to dissipate. The thermal solution should be designed to dissipate the TDP without exceeding the maximum Tjunction specification. TDP does not represent the power delivery and voltage regulation requirements for the processor."
See the Celeron section for why the Pentium III processor numbers have been revised downwards.
Tjunction offset is the worst-case difference between the thermal reading from the on-die thermal diode and the hottest location on the processor’s core. Tjunction offset values do not include any thermal diode kit measurement error. Diode kit measurement error must be added to the Tjunction offset value from the table. Intel has characterized the use of the Analog Devices AD1021 diode measurement kit and found its measurement error to be ±1° C
The 1.0B FC-PGA SL4WM Coppermine chip has a VID of 1.70V but it should receive 1.76V.

Tonga Notes:

Note that the core voltages for the mobile Pentium II processor have been adjusted down from 1.7v (1.58v~1.82v) to 1.6v (1.48v~1.72v). So the maximum amperages and wattages for the chips has also come down.
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 voltages and temperatures and under maximum signal loading conditions.
Maximum power dissipation is the total power dissipation while executing a worst-case instruction mix under normal operating conditions at nominal voltages. This includes the power dissipated by all of the processor components. Intel states that this is not 100% tested.
Maximum CORE temperature is measured by the thermal sensor mounted on the processor core.

Celeron 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 (which have not yet been specified) were measured at normal voltages while running Winstone96 under Windows95.
Maximum amperages were measured at maximum voltages and under maximum signal loading conditions.
Maximum power dissipation was measured at nominal core voltage.
Maximum power dissipation numbers have been radically lowered for the 533A and higher Coppermine-128 chips.
Max ambient temperature for the SECC and PPGA Celeron processor is specified at 45°C (air entering the fan on the boxed Celeron chip must be below this temperature).
The Max Power Dissipation is slightly different for the PPGA Celeron because it does not have GTL+ termination resistors.
The max wattage, amperage, and some max junction temperatures have been changed for Coppermine-128 Celerons. From the Celeron datasheet:
"The Thermal Design Power (TDP) Celeron^TM processors in production has been redefined. The updated TDP values are based on device characterization and do not reflect any silicon design changes to lower processor power consumption. The TDP values represent the thermal design point required to cool Celeron^TM processors in the platform environment while executing thermal validation type software."
TDP is listed as 'Max Power Dissipation' for the Coppermine-128 chips in this chart. "Thermal Design Power (TDP) represents the maximum amount of power the thermal solution is required to dissipate. The thermal solution should be designed to dissipate the TDP without exceeding the maximum Tjunction specification. TDP does not represent the power delivery and voltage regulation requirements for the processor." TDP numbers have changed for many Celeron procs. This does not represent a change in stepping; the values have just been updated.
Tjunction offset is the worst-case difference between the thermal reading from the on-die thermal diode and the hottest location on the processor’s core. Tjunction offset values do not include any thermal diode kit measurement error. Diode kit measurement error must be added to the Tjunction offset value from the table. Intel has characterized the use of the Analog Devices AD1021 diode measurement kit and found its measurement error to be ±1° C

Maximum power dissipation is the thermal design power (TDP) of the CPU. TDP is the "worst case power dissipated by the processor while executing publically available software under normal operating conditions at nominal voltages that meet the load line specifications. The TDP number shown is a specification based on Icc(maximum) and indirectly tested by Icc(maximum) testing. TDP definition is synonymous with the Thermal Design Power (typical) specification referred to in previous Intel datasheets. The Intel TDP specification is a recommanded design point and is not representative of the absolute maximum power the processor may dissipate under worst case conditions.

Xeon 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 normal voltages while running Winstone96 under Windows95.
Maximum amperages were measured at normal voltages and under maximum signal loading conditions.
Maximum amperages for the 256KB P-III Xeon CPUs (600~800MHz) have been increased. And while wattages have not changed, the FMB (Flexible MotherBoard suggested design guideline) has increased from 32 watts to 37 watts for both 2.8v and 5v/12v chips.
Maximum power dissipation is the worst case power that can be dissipated by the entire processor. It isn't possible for the AGTL+ bus, the L2 cache and the processor core to all be at full power simultaneously.
Maximum power dissipation on the Cascades CPUs is the Cartridge Power (the worst case power that can be dissipated by the entire processor). It isn't possible for the OCVR (on-cartridge voltage regulator), the L2 cache, and the processor core to all be at full power simultaneously.
Maximum power dissipation for the 1MB/2MB Cascades chips is the worst case power that can be dissipated by the processor, L2 cache, and 50% of the OCVR.
~~Wattage numbers for the 2.8v/5v/12v 600 and 667MHz chips has been revised upwards~~.
Power dissipation specifications (except for the 1MB/2MB 700MHz chip) have all been lowered (May 2000). This is not reflect a change in silicon, however.
Maximum plate temperature is the maximum temperature across the entire thermal plate.
Maximum cover temperature is measured at the four known hot spots on the SEC cartridge.
Note that some 400MHz Xeon processors have a 65° C max Tplate. See the Xeon Quick Ref Guide or Xeon Specification Update (linked below) for details.

P4 Notes:

Vmax is the maximum non-operating (failure) voltage.
Regarding the chip's wattage numbers, Intel states: "The [Thermal Design Power] numbers ... reflect Intel's recommended design point and are not indicative of the maximum power the processor can dissipate under worst case conditions."
The Estimated Max Power Dissipation numbers are based on the fact that Intel estimates the power dissipation for various software applications and sets the Thermal Design Point as the upper limit for how far these applications might push the Pentium 4. Intel states: "Processor power dissipation simulations indicate a maximum application power in the range of 75% of the maximum power for a given frequency." So the Est Max Power Diss was calculated by dividing the TDP by 75%. However, it's unlikely the CPU will reach its maximum power dissipation since the processor will throttle down the CPU speed as it reaches past certain temperatures. And in the event of a catastrophic cooling failure (i.e. leaving off the heatsink), it would completely shut down the CPU.
If the on-Die thermal probe reaches approximately 135° C (its catastrophic temperature), the CPU will automatically shut down and "the system bus signal THERMTRIP# will go active and stay active until the processor has cooled down and a RESET# has been initiated."
The VR Down design guideline allows a Pentium 4 processor in the 478-pin package to decrease its voltage as amperage increases.
The low wattage Pentium 4 Northwood chips are intended for small form factor systems and are limited to less than 45W maximum power output.

Vmax is the maximum non-operating (failure) voltage.
As Intel states in their docs, the P-4M voltages are simply targets. Vcc is a typical voltage with the minimum being defined by how much current is drawn at that voltage.

Celeron Notes:

Vmax is the maximum non-operating (failure) voltage.
Regarding the chip's wattage numbers, Intel states: "The [Thermal Design Power] numbers ... reflect Intel's recommended design point and are not indicative of the maximum power the processor can dissipate under worst case conditions."
The Estimated Max Power Dissipation numbers are based on the fact that Intel estimates the power dissipation for various software applications and sets the Thermal Design Point as the upper limit for how far these applications might push the Pentium 4. Intel states: "Processor power dissipation simulations indicate a maximum application power in the range of 75% of the maximum power for a given frequency." So the Est Max Power Diss was calculated by dividing the TDP by 75%. However, it's unlikely the CPU will reach its maximum power dissipation since the processor will throttle down the CPU speed as it reaches past certain temperatures. And in the event of a catastrophic cooling failure (i.e. leaving off the heatsink), it would completely shut down the CPU.
If the on-Die thermal probe reaches approximately 135° C (its catastrophic temperature), the CPU will automatically shut down and "the system bus signal THERMTRIP# will go active and stay active until the processor has cooled down and a RESET# has been initiated."
The VR Down design guideline allows a Pentium 4 processor in the 478-pin package to decrease its voltage as amperage increases.

Xeon Notes:

Vmax is the maximum non-operating (failure) voltage.
Regarding the chip's wattage numbers, Intel states: "The [Thermal Design Power] numbers ... reflect Intel's recommended design point and are not indicative of the maximum power the processor can dissipate under worst case conditions."
If the on-Die thermal probe reaches approximately 135° C (its catastrophic temperature), the CPU will automatically shut down and "the system bus signal THERMTRIP# will go active and stay active until the processor has cooled down and a RESET# has been initiated."
Core voltage varies with the amount of amperage being pulled by the CPU. Which is why the Prestonia's VID voltage (1.5v) is actually higher than it's maximum rated voltage (the chip will never actually be run at its VID voltage except under no-load conditions).
Max Processor Power for the Xeon MP is the "maximum thermal power that can be dissipated by the processor through the integrated heat spreader."
In Sep 2002, electrical numbers for the 2.6 and 2.8GHz Prestonia chips changed. Not sure why. Voltage limits were adjusted slightly downward. Amperage went up. Wattage decreased and max Tcase went up.

Itanium Notes:

For Abs. Max. Voltages listed in these tables Intel states: "Functional operation at the absolute maximum and minimum is neither implied nor guaranteed. The processor should not receive a clock while subjected to these conditions."
"Maximum current (Icc) specifications are intended for system power supply design. The maximum current is defined based on worst-case Vcc, temperature, and software mix."
"Maximum IccCore and IccCache do not occur simultaneously."
"The Intel Itanium processor protects itself from catastrophic overheating by use of an internal thermal sensor. The sensor trip-point is set well above normal operating temperature to ensure that there are no false trips. The Intel Itanium processor will stop all execution when the junction temperature exceeds a safe operating level. Data will be lost of the Intel Itanium processor goes into thermal trip (signaled to the system by THRMTRIP# pin). Once thermal trip is activated, the Intel Itanium processor remains stopped until RESET# is asserted."
For the Itanium 2: "Maximum thermal design power is an estimate of the power dissipation for the Itanium 2 processor offering while executing a worst-case application mix under nominal Vccps and worst-case temperature."
For the Itanium 2: "The maximum current specification is intended for system power supply design. The maximum current values are defined to be based on worst-case Vccps, temperature, and application mix."

Cyrix-III/C3 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.
"Case Temp" for the Ezra-T is actually junction die temperature.
