GPU-Z is a free Windows utility that reports detailed information about your graphics card. It is aimed at gamers, PC builders, technicians and anyone who needs to confirm exactly which GPU is installed before buying drivers, upgrading a system or troubleshooting performance.
The program reads the hardware and driver data that Windows exposes and presents it on a single, compact window. Because it does not change any settings, it is a low-risk tool to keep in your toolkit, and it works as a quick first step before you try anything more advanced like overclocking.
What Is GPU-Z and Who Is It For?
GPU-Z is a small information tool built by TechPowerUp. Its job is simple: tell you what graphics hardware is inside your computer and how it is configured. It does not benchmark your system or tune its performance.
The typical audience includes:
- Gamers checking whether a used card matches its listing
- People building or upgrading a PC who need to confirm compatibility
- IT staff and repair technicians diagnosing display problems
- Enthusiasts who want a quick snapshot of their hardware before tweaking anything
Common Real-World Scenarios
Here are a few situations where GPU-Z is handy:
- You bought a graphics card secondhand and want to verify its memory size and type before paying.
- A game asks for a specific GPU and you need to confirm what your PC actually has.
- You are choosing between two similar cards and want to compare their memory configuration.
- A driver installation failed and you need the exact device name to find the right package.
In each case the tool gives a fast, factual answer without requiring any setup.
Understanding GPU Memory Terms
Several terms appear in GPU-Z's readout, and it helps to know what they mean. VRAM is the dedicated memory on the card that stores textures, frame buffers and other graphics data. Memory type, such as GDDR6, describes the memory standard, which affects bandwidth and efficiency. Bus width indicates how much data can move between the memory and the GPU at once.
Understanding these values makes it easier to judge whether a card suits high-resolution gaming or other demanding workloads.

How to install GPU-Z on Windows
- 1
Download the official build
Go to the official TechPowerUp GPU-Z page at techpowerup.com/gpuz and download the Windows version. You can also find the release on the project's page if you prefer to check it there. Download only from the official website to avoid modified copies.

Verify the file
Before running the program, compare the file's SHA-256 checksum against the value published on the download page. On Windows, open PowerShell and run Get-FileHash followed by the file path. If the hash does not match, delete the file and download it again.

Run or install
GPU-Z is distributed as a portable executable as well as an installer. Choose whichever you prefer. Running the portable version requires no installation, while the installer adds a Start menu entry. Launch the program and it will read your graphics hardware immediately.
System requirements
- Windows operating system with a current, supported version
- A graphics card with a driver installed
How to use GPU-Z
GPU-Z is designed to work immediately after launch, with no configuration needed. The main window is split into tabs and fields that show your card's details as soon as the program starts.
To read your card's information and save its BIOS, follow these steps:
- Launch GPU-Z and check the Graphics Card tab for the model, memory type and size.
- Review the Sensors tab if you want live readings of clock speeds, temperatures and fan activity.
- To back up the firmware, click the small icon next to the BIOS version field and choose the save option.
- Store the saved BIOS file in a safe place, labeled with the date and card model.
- Use the Advanced tab for extra details about the GPU, such as supported technologies.
- Close the program when finished. GPU-Z leaves no background process running.
Pros & cons
- Free to use with no paid tier
- Lightweight and fast to start
- Shows detailed memory and GPU information
- Can save a BIOS copy for backup purposes
- Portable version requires no installation
- Informational only; it does not tune or optimize the card
- Interface is dense and may feel technical to beginners
- Limited to graphics hardware, not a full system report
Is GPU-Z safe?
GPU-Z itself is a read-only information tool, but any software that interacts with hardware deserves care. Download it only from the official TechPowerUp website or its official GitHub Releases page. Verify the file's SHA-256 checksum or signature before running it, and never download the program from third-party download sites that bundle extra software.
Antivirus tools occasionally flag hardware utilities because they read low-level system data. If that happens, confirm the file's checksum against the official value rather than disabling your protection. Keep your drivers and system updated, and be cautious about any firmware you flash after using a saved BIOS backup.
- Official source only. Download from www.techpowerup.com/gpuz. Ignore ads and lookalike domains.
- Check the SHA-256. Compare the installer hash with the value the developer publishes before running it.
- Never share your seed phrase. No developer, support agent or website — including CryptApps — will ever ask for it.
Alternatives
GPU-Z focuses on identification and information, which sets it apart from tools that actively change hardware behavior. MSI Afterburner, for example, is built for overclocking and undervolting, so it adjusts clocks and voltages rather than just reporting them. HWiNFO is broader, covering temperatures and sensors across the whole system, while GPU-Z stays concentrated on the graphics card.
If you only need to know what your GPU is and how much memory it has, GPU-Z is the simpler choice. If you want to tune performance or monitor the entire machine, pairing it with a tool like HWiNFO or MSI Afterburner makes more sense.

Frequently asked questions
Yes, GPU-Z is free. It is offered as a no-cost utility for reading graphics card information on Windows. Always obtain it from the official TechPowerUp website to make sure you receive the genuine version.
No. GPU-Z is designed to display information and save a copy of the BIOS. It does not overclock, undervolt or modify the card's configuration. That makes it a safe starting point before using any tuning software.
Yes, GPU-Z can save the current BIOS of your graphics card to a file. Keeping that backup is a sensible precaution before flashing new firmware, because it gives you a reference copy if you need to restore the original.
Open GPU-Z and look at the Graphics Card tab. The memory type and size appear in the fields near the top of the window. This is the quickest way to confirm whether your card uses GDDR5, GDDR6 or another standard.
It is safe when downloaded from the official TechPowerUp site or the official GitHub Releases page. Check the file's SHA-256 checksum before running it, and avoid third-party download portals that may bundle unwanted software.
GPU-Z concentrates on the graphics card, showing its model, memory and BIOS details. HWiNFO covers the entire system, including processor, motherboard and many sensors. Many users run both, using GPU-Z for quick GPU checks and HWiNFO for broader monitoring.
No. A portable version is available that runs directly without installation. If you prefer the installer, it adds a Start menu shortcut for convenience. Either way, the program reads your hardware as soon as it launches.
Verdict
GPU-Z is a free, focused tool for anyone who needs to know exactly what graphics card is installed and how its memory is configured. It is especially useful for checking secondhand hardware, confirming compatibility, and saving a BIOS backup before any firmware work. It does not tune performance, so pair it with a monitoring or tuning utility if you need more control.
