Most computer users usually do not need to access information that an application like GPU-Z provides them with. The free portable software for Windows is a tool that displays detailed information about the system’s video card.

Next to the cards name you find dozens of information listed in the program’s interface on startup. From the bios version and number of transistors to the vendor, pixel fillrate and clock speed information.

There are a few information that may be useful to users though. If someone asks you about your video card, e.g. a support technician for a game company, you can provide the technician with the details by running GPU-Z.

It can also be useful to find out if there are firmware updates available for the card, and whether it is running in its normal boundaries or is over- or underclocked.

GPU-Z also lists which computing technologies the card supports, including OpenCL, CUDA and PhysX.

A click on the Sensors tab in the program interface reveals additional information about the card that you may find useful. Probably the most interesting are the temperature sensors that reveal the temperature of the card. If you experience crashes or issues while playing games or gpu intensive applications, then you may want to check here to see if the temperature is at a very high level as it can be the cause for these issues.

Here you also find clock related information, the fan speed and rounds per minute settings, as well as the current memory use and load information.

GPU-Z is a specialized application, but still really helpful in certain situations. It is available for all 32-bit and 64-bit editions of the Microsoft Windows operating system. Downloads are provided at the website of the development company.
