Free PC Hardware Testing Software: CPU-Z

December 12th, 2007

CPU-Z is a handy little detection and testing program that will display detailed information about the hardware specifications of your PC. The application is approximately half of a megabyte in size and is very easy to use. All you need to do is download it, unzip it, and click on the file named “cpuz.exe”. After a few seconds of loading time, you should see it open in a new window that looks something like this:


The display consists of six tabs that will provide the following information:

  1. name, vendor, package, technology, and core voltage of your processor
  2. processor specs including core speed, multiplier, bus speed, and level 1-3 cache data
  3. manufacturer, model and chipset of your motherboard
  4. BIOS brand, version, and date
  5. graphic interface version and link width
  6. memory (RAM) information: type, size, number of channels, frequency, latency, cycle time, and other specifications
  7. on the About tab: author, version number, operating system specs, validation tools, and link to CPUID developers website

A wide variety of chipsets are supported, including most versions of Intel, AMD, nVidia, VIA, and ATI. The program is designed to work with all versions of Windows. You can download CPU-Z here for free and read other reviews about it at softpedia.com.

The only real disadvantage to CPU-Z that I have seen so far is that it is not compatible with the Linux operating system, and trying to find a comparable Linux version is currently rather difficult. In an attempt to satisfy the 3.6% of you who are using (mostly Ubuntu) Linux, I performed some searches and managed to come up with this hardware lister from ezix.org that is supposed to provide much of the same information that CPU-Z does.

However, it requires a little more technical savvy to use because you may need to unpack and compile the source code and then interpret the output. Fortunately the wiki page at ezix.org explains the details of its usage, installation, and capabilities. Meanwhile, if any of you have found (or designed) a more directly comparable Linux version of CPU-Z or a similar type of PC hardware testing software, please let me know in the comments section so that I can update this article with the most recent and useful information.

    The gtk-lshw (also mentioned on the page) is fairly similar, but it has a lot more information to grasp at once. Another solution is KInfoCenter (included with KDE), but frankly it isn’t any better than gtk-lshw.

    CPU-Z is giving me complete information about my processor when I run it in WINE on Kubuntu, but not as much in the other tabs.
