GPU-Z is a small-sized software utility that collects information on the computer's graphics card and sensors, while allowing users to supervise temperature, used memory and other data.
It features support for creating log files and comes in handy to all users looking to upgrade hardware, purchase a high-demanding video game, or simply compare the graphics card configuration with other systems.
It is possible to either install GPU-Z or launch it directly. Thanks to its portability, it is possible to save the tool to a USB flash disk or other removable storage unit, in order to run it on any PC easily and without previous installers. Plus, it does not modify Windows registry settings or create additional files on the disk without permission, thus leaving no traces behind after its removal.
As far as the graphics card is concerned, GPU-Z shows its name, GPU, revision, technology, release date, transistors, BIOS version, device ID, shaders, DirectX support version, pixel and texture fillrate, memory type and size, bus width, bandwidth, driver version, GPU and default clocks, and other details.
The application offers support for OpenCL, CUDA, PhysX and DirectCompute. If there are multiple graphics cards implemented into the PC unit, it is possible to view all these details for each one.
When it comes to the sensors, GPU-Z shows the GPU temperature, core, memory and shader clocks, fan speed in percentage and RPM, used memory, GPU, memory controller and video engine loads, along with the VDDC (memory voltage).
It is possible to disable any sensor, show a preferred one in the GPU-Z window title to monitor live usage easily, as well as set the tool to display either the actual, lowest, highest or average reading for each sensor. The information refresh rate can be changed (ranging from 100 milliseconds to 10 seconds); the program continues to refresh the screen even when it runs in the background, but this feature may be deactivated. What's more, all sensor information can be saved to a plain text document; it gets continuously updated by GPU-Z at the frequency set for the sensor refresh rate.
GPU-Z has a great response time and minimizes to the system tray area on close; holding the mouse cursor above it shows the live GPU temperature and load, along with used memory. We have not come across any issues throughout our tests, since it did not cause Windows to hang, crash or pop up error messages. To sum it up, GPU-Z is a must-have tool for any self-respectable power user who wants to keep track of their GPU temperature and analyze information in detail.
