[yash123]

Hi All,

The following is taken from out put of machinfo
Could anybody tell more about 31 family of processor.
Is there 32 family of processor?

This machinfo is from HP rx7620 ia64.

processor family: 31 Intel(R) Itanium 2 Family Processors
processor model: 2 Intel(R) Itanium 2 processor
processor revision: 2 Stepping A2

Hi Yash,
>>Could anybody tell more about 31 family of processor.

<<<

The following line is important:

processor family: 32 Intel(R) Itanium 2 9000 series

Intel named the Montecito CPU family "9000",

see

http://www.intel.com/products/processor_number/chart/itanium2.htm

Previous model is for example:
processor family: 31 Intel(R) Itanium 2 Family Processors

Thanks,
Johnson

Family 31 is 1F hex, now compare

Family number Model number Processor
0x07 0x00 Itanium Merced
0x1F 0x00 Itanium 2 McKinley
0x1F 0x01 Itanium 2 Madison, Deerfield, Hondo
0x1F 0x02 Itanium 2 Madison 9M, Fanwood
0x20 0x00 Itanium 2 9000 series Montecito


Family 32 is Montecito, but naming changed - it is now Intel 9000 series

machinfo
CPU info:
1 Intel(R) Itanium 2 9000 series processor (1.4 GHz, 12 MB)
399 MT/s bus, CPU version C2
2 logical processors (2 per socket)

According to the list you have Madison 9M or Fanwood, now compare to this:

Let me add this - names are always a problem.

The Intel code names are obviously not used by hp for older models.

The quickspecs name these CPUs

...Processor Configuration The HP Integrity rx7620 Server is a symmetrical multiprocessing (SMP) server supporting:

up to 8 high performance 64-bit Intel Itanium 2 1.6-GHz 6-MB cache or 1.5-GHz 4-MB cache processors.
...

Now it is up to you to find out what the "64-bit Intel Itanium 2 1.6-GHz 6-MB cache" is.

Nowadays this is no longer unique.


With newer system it is a bit easier, see

... Intel Itanium 9150N (Montvale) ...

My previous posting was sent before I could read yours.

According to the information you have

Family 1F (31)
processor model: 2

This is

0x1F 0x02 Itanium 2 Madison 9M
