Determining CPU Speed in AIX Contents About this document Procedure About this document This document applies to AIX Versions 4 and 5. Procedure 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 themmvalues from the uname -m output with the table below, you can easily determine the processor speed. To determine cpu speed with AIX V5, use the following command: lsattr -El proc0 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.

However, in some cases the information gained from the uname -M command can be helpful. uname -M Machine Type Processor Speed Processor Architecture IBM,7017-S70 7017-S70 125 RS64 IBM,7017-S7A 7017-S7A 262 RD64-II IBM,7017-S80 7017-S80 450 RS-III IBM,7017-S85 pSeries 680 600 RS64-IV IBM,7025-F40 7025-F40 166/233 PowerPC 604e IBM,7025-F50 7025-F50 See Note 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. Only 6-way (F-80) systems run at 500 MHz, all others run at 450 MHz. Use the L2cache size to determine the speed of the cpu: lsattr -El L2cache0 L2cache size CPU speed 1mb 333MHz 4mb 400MHz 8mb 450MHz 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). The Model 6M1 delivers a cost-efficient growth path to the future including 64-bit system scalability providing 2-, 4-, 6-, and 8-way configurations with combinations of the following processor options: ? 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 Use the L2cache size to determine the speed of the cpu: lsattr -El L2cache0 Each 375 MHz processor includes 4 MB of Level 2 (L2) cache, and each 450 MHz processor includes 8MB of L2 cache.
