About Graphics Cards (GPUs)
A Graphics Processing Unit (GPU), also called a graphics card or video card, is the hardware component responsible for rendering images, videos, and animations on your screen. GPUs are essential for gaming, video editing, 3D modeling, and other graphics-intensive tasks.
Major GPU Manufacturers
- NVIDIA: Known for GeForce RTX and GTX gaming cards, also makes professional Quadro cards
- AMD: Produces Radeon RX gaming cards and professional Radeon Pro series
- Intel: Makes integrated graphics (Intel HD, Iris Xe) and Arc discrete GPUs
- Apple: Custom M-series chips with integrated GPUs for Mac devices
Why Check Your GPU?
- Determine if your system meets game or software requirements
- Verify GPU upgrade installations
- Troubleshoot graphics-related issues
- Check if you have dedicated or integrated graphics
- Identify your GPU for driver updates
- Compare your hardware to recommended specifications
WebGL Detection Method
Our tool uses WebGL (Web Graphics Library) to detect your GPU. WebGL is a JavaScript API that allows browsers to render 3D graphics without plugins. Through WebGL, we can access information about your graphics card vendor and renderer string, which reveals your GPU model.
Integrated vs. Dedicated GPUs
Integrated GPUs are built into your CPU and share system memory. They're power-efficient but less powerful, suitable for basic tasks and casual gaming. Dedicated GPUs are separate cards with their own memory (VRAM), offering significantly better performance for gaming, video editing, and professional graphics work.
Limitations of Browser Detection
Browser-based GPU detection has limitations due to security and privacy restrictions. We can identify your GPU model through WebGL, but cannot access detailed specifications like VRAM size, clock speeds, or temperature. For complete GPU information, use system tools like GPU-Z (Windows), System Information (macOS), or lspci (Linux).
Frequently Asked Questions
How can I find out what GPU I have?
You can find out what GPU you have by using our free online GPU detector, which uses WebGL to identify your graphics card model and vendor instantly in your browser. Alternatively, on Windows you can check Device Manager or run dxdiag, on macOS use About This Mac > System Report, and on Linux use the lspci command.
What is the difference between an integrated and dedicated GPU?
An integrated GPU is built into the CPU and shares system RAM, making it power-efficient but less powerful. A dedicated GPU is a separate card with its own video memory (VRAM), offering significantly better performance for gaming, video editing, 3D rendering, and other graphics-intensive tasks.
Why does my browser show a different GPU than expected?
Browsers may report a different GPU because many laptops and desktops have both integrated and dedicated graphics. Browsers often default to the integrated GPU for power savings. You can change this in your GPU control panel (NVIDIA Control Panel or AMD Radeon Settings) by setting the browser to use the high-performance GPU.
Can a website detect my GPU's VRAM or clock speed?
No, websites cannot detect detailed GPU specifications like VRAM size, clock speeds, or temperature through a browser. Web-based detection is limited to the GPU model name and vendor via the WebGL API. For full specifications, use native tools like GPU-Z on Windows, System Information on macOS, or glxinfo on Linux.
