PID: 30430 Rev 3.51 March 2006 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. 2 FIDVID Status Register, M SR C001_0042h. 3 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. 5 Implementation of this P-state is optional in BIOS. 6 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. 7 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 p rocessors.

AMD Athlon™ 64 X2 Dual Core Processor
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 AMD Athlon™ 64
and AMD Opteron™ Processors, order# 26094.
2
FIDVID Status Register, MSR C001_0042h.
3
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 Max, IDD Max, and VDD=VID_VDD,
and include all power dissipated on-die from VDD, VDDIO, VLDT, VTT, and VDDA.
5
Implementation of this P-state is optional in BIOS.
6
StartVID and MaxVID 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, MaxVID, and
VID_VDD will
be specified for the corresponding OPN. For information on the relationship of StartVID and MaxVID to
VID_VDD refer to the BIOS and Kernel Developer’s Guide for AMD Athlon™ 64 and AMD Opteron™
Processors, order# 26094.
Contact your FAE for more info on TDP specifications.
7
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
AMD Athlon™ 64 and AMD Opteron™ Processors, order# 26094, for details on P-state operation for dual core
processors.
