5 tools to test computer performance

To test, estimate the average performance of a computer or decide to change one of its components, you need to know the ins and outs. Each of the tools that you will find here display the most intimate information of your components or are able to push them to their limits, just to know if they deliver the expected performance.

The majority of these tools offer French as the operating language, however many are still in English.


Considered a "all-in-one "PC monitoring and auditing, Speccy is the software you need to install on your PC. It recognizes all of your components and can even detect up to the serial number of your Windows: temperature, actual frequencies, status of Smart information for hard disks, nothing escapes it.

Fans of "hacking" and overcloking appreciate it for its ability to display hidden information such as latency, preload or cycle times of a memory module. This software allows you to take a complete picture of a machine when you are looking to upgrade it or to obtain the exact reference of one of its components.



Since its launch, CPUZ  is a benchmark in the field of processors. It is even able to list rare processors as its database is complete. Its interface still looks like the one we found in Windows XP. It also displays information from motherboards, memory, and even graphics cards. Warning, his specialty remains the processor for which it manages to indicate the frequencies in real time.


CrystalDisk Info and CrystalMark

Even with the Smart functions, it is still difficult to know the status or performance of its hard drives. With Crystal Disk Info et Crystalmark, you will know everything. The first is not just for knowing how your hard drives are doing, but it also lists all the information on their characteristics or functions. CrystalMark takes care of testing your units. and show you the average read and write performance for different file sizes.

TechPowerUp GPU-Z  

TechPowerUP done like CPUID, but only interested in graphics processors, but also knows many frequencies in monitoring. Available in its only English version, the software truly displays all the information of your GPU. Regarding the monitoring of functions via the sensors on your card, you must once again switch the display to a secondary monitor, just to read them in real time while the main monitor is running test software or a game. .

SiSoft Sandra

Long time, SiSoft Sandra was a benchmark in the field of testing, but also PC diagnostics. Today, the software is still just as powerful, but the functions accessible free of charge are less and less important and you have to quickly pay for a "home" version for those who want to try their hand at optimization. For the rest, no doubt, this tool combines all the power and possibilities of the previous versions. We like the interface and the user-friendliness of the whole, as well as its ability to display rather relevant optimization information.
