3rd table column with caption "ЦПУ(МГц)" is CPU speed in MHz. Other columns are
1 - CPU model, 2 - Server/Oracle version, 4 - Bus speed, 5 - CPUSPEEDNW, 6 -
CPUSPEED, 7 - Source (link to the post).

Before posting I had goggled the topic and saw this thread. It was very
interesting however the actual clock speed of the cpu's weren't posted so I
didn't know if there was a correlation or not.
Thank you.
Ken

BTW if you need some numbers to compare, here is a link to SQL.ru thread on
this topic with CPUSPEED/CPUSEEDNW data for some CPUs/Oracle versions:

Ken,
There is no direct correlation. The values that I have seen from many customers
are in the range between 1,000 and 1,600.
