Power and Thermal Data Sheet
10Overview
1.3 Definitions
Following are some key definitions.
• CPU COF. CPU Current Operating Frequency.
• CTP. Composite Theoretical Performance.
• Dual-plane. Platforms in which the VDD and VDDNB (Northbridge) planes are isolated on the
platform and controlled as separate voltages.
•DP. Dual Processor. Each link on DP models supports connections to I/O devices, and any one link
or any sub-link can connect to another MP or DP processor.
• MP. Multiprocessor. Each link on MP models supports connections to I/O devices or an MP or DP
processor. Systems are limited to the number of nodes supported by all the processors. Refer to the
BIOS and Kernel Developer’s Guide (BKDG) for AMD Family 10h Processors, order# 31116, for
more details.
• MTOPS. Millions Of Theoretical Operations Per Second.
• NB COF. Northbridge Current Operating Frequency.
• OPN. Ordering Part Number. An OPN uniquely identifies a processor and its associated
specifications in the thermal and power tables and power supply specifications section.
• P-state. Processor Performance State. P-states are valid combinations of CPU voltage, CPU COF,
Northbridge voltage, and NB COF.
• Single-plane. Platforms in which all the VDD and VDDNB power planes are connected together
on the platform and controlled as a single power plane.
• SOPN. Subsection Ordering Part Number. An SOPN is an OPN with a subset of defined characters.
All defined characters in an SOPN are bolded and capitalized. All abstracted characters in an SOPN
are in non-bolded lowercase. Information for any OPN that matches all of the defined characters in
an SOPN is contained in that subsection. For example, OPN AB12344CDE5FGH appears under the
subsection for SOPN AB mmmmmrrpnc GH. The abstracted (lowercase) character definitions for
SOPNs are contained in the OPN description section of each chapter.
• State. Indicates the ACPI defined sleep state, power state, and performance state for the related
specifications. 'x' indicates the related specifications are independent of the associated ACPI state.
For example, S0.C0.P0 indicates sleep state 0, power state 0, and performance state 0. S3.Cx.Px
indicates sleep state 3 entered from any power and performance state combination.
• TDP. Thermal Design Power. The thermal design power is the maximum power a processor can
draw for a thermally significant period while running commercially useful software. The
constraining conditions for TDP are specified in the notes in the thermal and power tables.
• UP
. Uniprocessor. Each link on UP models supports connections to I/O devices.
