The following is the entire content of an IBM Supportline ticket on getting the clock speed from and AIX machine via software. The gist of this document which will become readily apparent is that you have to know the machine ID in order to equate that to a list of speeds. On some of the newer PCI based machines, one is able to actually use the provided system calls to get the information desired.

We have a resource controller code that needs to know the clock speed of
the processor running under its control in order to calculate some of
its information properly.  On other systems we have been using the
sysconf(_SC_CLK_TCK) call to get this.  Under AIX it appears that this
value is set to 100 via the /usr/include/unistd.h file.  How can I get
the real clock speed?  I would like something in MHZ if possible.

There isn't a command that will allow you to check the time clock on
the hardware.  There are charts that we have developed and there are
sales manuals that are internal to IBM that we have access to.
I did collect the information except for the SP because there are
numerous nodes in the SP and each one will process at it's own level.
By running the 'uname -m' you can acquire the CPU ID number which is used
to verify what speed the clock runs for each node.
For the other 3 I was able to come up with clock speeds for you:
     99J 71.5 MHz
     580 62.5 MHz
     c20 120 MHz
If you want the SP speeds just send the CPU ID numbers in and we can
identify the rest for you.
Thank you for using AIX Technical Support.

We depend on the sysconf() routine to do our work.  Hard coding a model
number to translate to a seems like a messy cludge.  I must be able to
get the speed via the system somehow.  When will sysconf() return a real
value that can be used?  On an E30, I can get the 233 MHZ value by using
'lscfg -vp' and the value shows up under the PLATFORM SPECIFIC section
under the procF0 device, ZA field:
 lscfg -pvl procF0

Is there any of this available on the RS6K architecture somewhere?

   Until recently, the model and processor type/speed were irrevocably
bound together.  If you upgraded your processor, the model number of
the system changed.  This has changed with the upgradeability of the
RSPC systems.  At this time, there are no plans for the sysconf() call
to return the processor speed.  You may wish to contact your marketing
representative or point of sale to submit a DCR (Design Change Request)
to have the sysconf() call recoded to provide this information.
   The processor speed information is not uniformly available across
the RS/6000 product line.  Until such a time as development recognizes
a need for this information to be uniformly available and provides a
method for procuring it, the best way for you to get this information
will be by using the uname -m command output.

Ok, If I'm stuck with a lookup table, here are the machine types that
we currently have installed.  If you have an electronic form of this
that is all-inclusive of all models, that would be best, but at a
minimum I need the following list completed.  Everywhere there is a '*'
is information I do not have.  Please complete the missing information
and double check my research.  The 'Model' column is the model info
obtained from the uname man page (which is apparently out of date), and
the 'Front Panel' column is what the machine indicates it is by virtue
of its label.

An all inclusive list would be better if available.  This could be
put into this item or, even better, e-mailed to

Belows is the all inclusive list for the CPU ID and which model this
goes to.  From there the second list should be able to give you how
fast the system is running.  I hopes this helps you.

The first list below gives the CPU ID and which model it goes to.
