P4/P4 EE 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.
  • Max Cover Temp (Tc) for Prescott is approximated from the thermal profile given in the datasheet.
  • Some of the Socket T chips have a PRB (platform requirement bit) set to indicate specific platform requirements (higher amperage and wattage).
