CPU-Z screenshotCPU-Z is a freeware tool that collects information on some of the main components of your system :

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

In terms of user interface, CPU-Z has always adopted a simple look with no visual highlights. Regarding the technical nature of the tool, the look is not that important anyway, as long as data is neatly organized, and CPU-Z sticks to that rule.

At startup it may take a longer time to load all modules, separately classified into CPU, mainboard, caches, memory, SPD and graphics data. Some details are shown in real time, like the current core and bus speed, with rated FSB. All information can be exported to a HTML file or a plain text document for closer analysis and safekeeping. Additionally, this data can be submitted online to the developer to confirm it.

The program won't affect your computer's performance, being light on CPU and RAM memory. It displays accurate data and worked smoothly during the tests, without triggering Microsoft Windows to hang, crash or popup error messages, so users working on older OS versions should not worry.
