AMD Athlon™ 64 Processor Power and Thermal Data Sheet
Notes:
1
CPUID extended function 8000_0001h fields are used by BIOS in uniquely associating a given processor to the P-
states that are valid for that processor. Refer to the BIOS and Kernel Developer’s Guide for AM D Athlon™ 64
and AM D Opteron™ Processors, order# 26094.

FIDVID Status Register, M SR C001_0042h.
The VID_VDD voltage is the VID[4:0] requested VDD supply level. Refer to the appropriate functional data
sheet for details.
4
Thermal Design Power (TDP) is measured under the conditions of Tcase M ax, IDD M ax, and VDD=VID_VDD,
and include all power dissipated on-die from VDD, VDDIO, VLDT, VTT, and VDDA.
Implementation of this P-state is optional in BIOS.

StartVID and M axVID are programmed during device manufacturing with part-specific values for Rev E and later
processors, and can have one or more valid options. All valid options for StartVID, M axVID, and VID_VDD will
be specified for the corresponding OPN. For information on the relationship of StartVID and M axVID to
VID_VDD refer to the BIOS and Kernel Developer’s Guide for AM D Athlon™ 64 and AM D Opteron™
Processors, order# 26094. Contact your FAE for more info on TDP specifications.
Thermal Design Power (TDP) specifications for dual core processors assume equivalent P-states (Voltage and
frequency) and equivalent Tcase conditions for both cores. Refer to the BIOS and Kernel Developer’s Guide for
AM D Athlon™ 64 and AM D Opteron™ Processors, order# 26094, for details on P-state operation for dual core
processors.
