Processor details in Windows XP

Question

I am using Windows XP - SP2. How can I check how many processors are available in my system and how many cores in each?

Answer 1

Use CPU-Z to identify your processor information

Answer 2

You can also use the new tool Speccy, by Piriform (the guys who made CCleaner).

Answer 3

From the command line you can use WMIC:

> wmic cpu get numberofcores,numberoflogicalprocessors
NumberOfCores  NumberOfLogicalProcessors
2              2

For a multi-processor setup you should get one result line per CPU.

Answer 4

If you already have Powershell downloaded, you can execute the following.

Get-WmiObject -Class “Win32_Processor” -Namespace “root\CIMV2″ | Get-Member

Then look at NumberOfCores NumberOfLogicalProcessors values. It uses Windows Management Instrumentation just as Joey's does, but you have more options in what you do with the info over the Windows Management Instrumentation Command-line (WMIC). For example you can add

| tee C:\cpuInfo.txt
