Determining CPU Speed in AIX

Technote (FAQ)


Question

Determining CPU Speed in AIX

Answer


This document applies to AIX Versions 4 and 5.

While there is not a direct command to determine processor speed in AIX V4, the best place to start is with the uname command. Executing uname -m produces output of the following form:

          xxyyyyyymmss
The meanings of the placeholders are as follows:
           xx = 00
       yyyyyy = Unique CPU ID
           mm = Model ID <- these are the numbers to use to determine CPU speed
           ss = 00 (Submodel)

By cross-referencing the values from the uname -m output with the table below, you can easily determine the processor speed.

To determine cpu speed with AIX V5 (which includes power5 systems and above), use the following commands:

     lsattr -El proc0
     prtconf
     pmcyles -m 

The frequency line returns the speed of the cpu. Note on some machines the value represented by the frequency line will have to be rounded to the nearest integer. For example, the frequency reported on a 7025-F80 is 451200000, which is then rounded to 450MHz.

NOTES:

  1. Systems where uname -m outputs a model ID of 4C:

    In general, the only way to determine the processor speed of a machine with a model ID of 4C is to reboot into System Management Services and choose the system configuration options. However, in some cases the information gained from the uname -M command can be helpful.

  2. J-Series, R-Series, and G-Series systems:

    You can determine the processor speed in an MCA SMP system from the FRU number of the CPU card by using the following command:

              lscfg -vl cpucard0 | grep FRU
    

    This will produce the following output:

              FRU Number..................C1D 
     FRU Number    Processor Type    Processor Speed
    E1D           PowerPC 601       75
    C1D           PowerPC 601       75
    C4D           PowerPC 604       112
    E4D           PowerPC 604       112
    X4D           PowerPC 604e      200
    
  3. E-Series and F-30 systems:

    For the E-series and F-30 systems, use the following process to determine CPU speed. Execute:

               lscfg -vp | more
    

    Look for the following stanza:

    In the section Device Specific.(ZA), the section PS= (boldface here) is the processor speed in MHz.

  4. F-50 and H-50 systems and SP Silver Node:

    The following commands can be used to determine the processor speed of an F-50 system. Execute:

              lscfg -vp | more
    

    Look for the following stanza:

    Orca M5 CPU:
      Part Number.................08L1010
      EC Level....................E78405
      Serial Number...............L209034579
      FRU Number..................93H8945
      Manufacture ID..............IBM980
      Version.....................RS6K
      Displayable Message.........OrcaM5 CPU DD1.3
      Product Specific.(ZC).......PS=0013c9eb00,PB=0009e4f580,SB=0004f27 
    ac0,NP=02,PF=461,PV=05,KV=01,CL=1
    

    In the line containing Product Specific.(ZC), the entry PS= (boldface here), is the processor speed in hexadecimal notation. To convert this to an actual speed, use the following conversions:

    0009E4F580 = 166 MHz
    0013C9EB00 = 332 MHz

    The valuePF= indicates the processor configuration.

    251 = 1 way 166 MHz
    261 = 2 way 166 MHz
    451 = 1 way 332 MHz
    461 = 2 way 332 MHz

    Each 2 way processor resides on one CPU card. 4 way systems will display two entries for the Orca M5 CPU card.

  5. Only 6-way (F-80) systems run at 500 MHz, all others run at 450 MHz.

  6. Use the L2cache size to determine the speed of the cpu:
         lsattr -El L2cache0
    
    L2cache size  CPU speed
    1mb           333MHz
    4mb           400MHz
    8mb           450MHz
    
  7. It can be configured with 1-, 2-, 4-, or 6-way, RS64 III or RS64 IV, 64-bit processors. Systems configured with the maximum of six processors run at 668 MHz, while other configurations run at 600 MHz (RS64 IV) or 450MHz (RS64 III).

    To determine the number of processors on the system run lsdev -Cc processor and to determine the type of processor run lsattr -El proc0.

  8. The system 7026 Model 6M1 (p660) has two processor slots to accommodate two 2-way or 4-way processor cards to create a system with 2, 4, 6, or 8 processors. Each processor slot can hold one of the following processor cards:

    2-way 750 MHz RS64 IV with 8 MB L2 cache per processor
    4-way 750 MHz RS64 IV with 8 MB L2 cache per processor
    2-way 500 MHz RS64 III with 4 MB L2 cache per processor
  9. To determine the number of processors on the system run lsdev -Cc processor and to determine the type of processor run lsattr -El proc0.

  10. For pSeries servers that use a 350 MHz or 450 MHz processor, run the following command

    lscfg -vp | more

    Then look for the Processor Card entry. The PF field, in the Product Specific (ZC) line, indicates the processor type as follows:
      PF Value          Card type                                    FRU p/n
      754               375 MHz One way card w/ 4 MB L2 cache        09P0399
      764               375 MHz Two way card w/ 4 MB L2 cache        09P0406
      768               375 MHz Two way card w/ 8 MB L2 cache        09P0143
      7A8               450 MHz Two way card w/ 8 MB L2 cache        09P4478
