Finding The Processor Type
ITman
When you right-click My Computer and choose "Properties",
in the "General" Tab you can find the section "Computer"
which describe the processor type as:
x86 Family 6 Model 8 Stepping
How can i write a function that returns
the processor type and speed that will look like:
Pentium III 750 Mhz

In my version of a "get CPU family" I did not use the CPU.Family method. It
looks like this property is not to be trusted, it does not return correct
numbers. I have tried both WinXP and Win2k on different types of machines, both
PIII and P4, and I mostly get returned "2" from CPU.Family. That's a "8086"
processor ;-)
Alex, what does it return for you? Could anyone else as well try the script
provided by Alex and report back the findings?
I think it is safer to analyze the Win32_Processor.Description, and map it to
the correspondending CPU family. Se my script below.
And if you don't want to/cannot use WMI, you can substitute the WMI part of the
script with a RegRead from
HKLM\Hardware\Description\System\CentralProcessor\0\Identifier. It returns
exactly the same as WMI Win32_Processor.Description.
If you do use a RegRead, note that it is only WinNT/Win2k/WinXP that returns
data in the format "x86 Family 6 Model 8 Stepping 3". Win98/WinME will return
the processor family directly, like this: "Pentium(r) II Processor". Note also
that Win95 does not have the value Identifier in registry.
Here is the script that interprets the data returned by
Win32_Processor.Description:
Select Case CpuID
Case 4
WScript.Echo "Pentium 4"
Case 3
WScript.Echo "Pentium 3"
Case 2
WScript.Echo "Pentium Pro/II or Celeron"
Case 1
WScript.Echo "Pentium or Pentium MMX"
Case Else
WScript.Echo "Unknown CPU type"

The registry setting you point to below is reflected
in the win32 api System_Info structure:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/sysinfo/sysinfo_5r76.asp
which can be used to decode the registry value also.

I didn't even think about the model list when I ran my test - and my P3
shows up as an "M2"...

Microsoft punted on it. Family/Model/Stepping isn't enough to successfully
translate to the marketing name. On recent model AMD processors, the BIOS is
supposed to put a description string into the SMBIOS area like "Athlon XP
1800+" and that should be available through WMI. The only reliable way I
know to get the actual MHz is to use the processor's RDTSC instruction.

Hi

I installed the utility and ran it. The results can be exported to a text file, here is the

It looks like the "Family" value in Win32_Processor is not the one from the
CPUID instruction but the one from the SMBIOS specification "Processor
Family", section 3.3.5.2 of the spec. My P3 shows up as 17 (11h) which is
the correct code for a Pentium III. The most up to date values are probably
in the master.mif file on the DMTF site since that's essentially the "source
code" for all the encodings.

identical to the WMI SDK listing with the numbers off by one. The
Microsoft SDK listing starts with 0; the DMI spec starts with 1.

I have found that the description part is different in W9x than for NT-based OSs.
Win95 will give "CPU 0", Win98 will state the processor family name directly, e.g.
"Pentium(r) II Processor". The script need some redesign to support W9x;-)
What would be very interesting, would be to get some results from someone with AMD
or Cyrix !
If somebody could post back some AMD/Cyrix results from the script below, it would
be very nice :-)
Set oWMI = GetObject("winmgmts:")
For Each oCpu in oWMI.InstancesOf("Win32_Processor")
