GPU-Z is TechPowerUp's free Windows utility for viewing GPU specs and monitoring temperature, clocks, load, and fan speed in real time.
GPU-Z is a free system utility from TechPowerUp, first released in October 2007, that reports detailed information about a computer's graphics card. It reads directly from the GPU and driver to show model, architecture, memory configuration, clock speeds, and BIOS version, giving hardware enthusiasts and IT technicians a quick way to identify exactly what graphics hardware is installed.
Beyond static specs, GPU-Z also functions as a real-time monitoring tool, tracking sensor data such as temperature, load, fan speed, and clock behavior as the system runs. It is distributed as a single portable executable, so it can be run without installation, which makes it convenient for checking multiple machines.
GPU-Z supports graphics cards from NVIDIA, AMD, ATI, and Intel, displaying core specifications alongside live sensor readouts for temperature, GPU/memory clock speed, fan speed, voltage, and load. It can log these sensor readings to a text file over time, which is useful for diagnosing thermal or stability issues during extended use, such as gaming or mining sessions.
The tool also includes a GPU BIOS backup/save feature, letting users create a safety copy of their card's BIOS before attempting a flash or modification. GPU-Z does not include its own stress-testing or benchmarking suite, and it has no overclocking controls, focusing instead purely on information and monitoring.
GPU-Z is completely free to download and use, for both personal and commercial purposes, with no paid tier, subscription, or license fee. There is no premium or pro version of the tool.
Because it's a free utility rather than a commercial software product, there are no pricing plans, trials, or feature gating — every user gets the full feature set at no cost directly from TechPowerUp's website.
