CPU-Z is a freeware application that has been around for over 20 years. Modern CPUs contain a set of instructions, that when activated, provide a wealth of information about the processor: brand, model, number of cores, cache levels, and so on.

In addition to the brains of the computer, it also displays similar information about the motherboard and system memory, including:

  • Processor name and number, codename, process, package, cache levels
  • Mainboard and chipset
  • Memory type, size, timings, and module specifications (SPD)
  • Real time measurement of each core's internal frequency, memory frequency

Why is CPU-Z so popular?

CPU-Z is popular among PC enthusiasts as it offers up to date, detailed, and accurate data about the hardware found in your computer. CPU-Z is a relatively simple application that does well what it's supposed to do.

What's one favorite CPU-Z feature?

CPU-Z offers a hardware validation feature. With just a click you will receive a link with all your system specs that you can share with others. You can use this report to show proof of your hardware and its capabilities, or just as a record of your system's status at any given time.

Is the CPU-Z benchmark any good?

CPU-Z is first and foremost a system information and monitoring tool. The included benchmark is a good simple tool, but it's not meant to be thorough. Cinebench is a more comprehensive CPU benchmark, you can also check out our guide on benchmark and hardware analysis tools apps.

Can I use CPU-Z to stress test my CPU overclock?

While CPU-Z includes a basic stress test feature, it's not as rigorous as dedicated tools. For thorough stability testing of overclocks, utilities like Prime95, AIDA64, or OCCT are recommended, as they can apply more intensive and varied workloads to your CPU.

Why doesn't CPU-Z reflect my BIOS overclock settings?

If CPU-Z doesn't show your expected overclocked speeds, it might be due to power-saving features like Intel's SpeedStep or AMD's Cool'n'Quiet, which lower frequencies during idle periods.

Why does CPU-Z show different CPU speeds compared to Task Manager?

CPU-Z provides real-time readings of your CPU's core speeds, which can fluctuate due to power-saving features and dynamic frequency scaling. Task Manager may display an average or base speed, leading to discrepancies between the two.

The Android version of CPU-Z reports information about your mobile devices:
