GPU Info & Capabilities
This report lists what your browser is willing to tell a web page about your graphics stack: the GPU name it reports, which of WebGL, WebGL 2 and WebGPU are available, texture and buffer limits and the extension list. It is the first thing to check when a test refuses to start or a web app runs slowly.

About this tool
The tool asks your browser for its graphics information and shows it in a table. It reads the reported GPU name and vendor, whether WebGL 1, WebGL 2 and WebGPU are available, limits such as maximum texture size, the number of CPU threads and approximate device memory.
It cannot show exact VRAM, temperatures, clock speeds or driver versions, because browsers do not expose them. Browsers may also mask or generalise the GPU name for privacy, so the name shown can differ from the box your card came in.
How to read the results
Reported GPU. If you see a software renderer such as SwiftShader or llvmpipe, hardware acceleration is off or unavailable and every benchmark will run far slower than your real GPU can.
Max texture size. The largest single texture side the GPU accepts. 16384 is typical on desktop GPUs; 4096 or 8192 is common on phones.
Anisotropic filtering. Keeps textures sharp at oblique angles. 16 is the usual desktop maximum.
WebGPU. Shows whether the newer API is available. Larger storage-buffer and workgroup limits allow bigger compute workloads such as the matrix test on this site.
Frequently asked questions
Why does it show the wrong GPU, or a generic name?
Browsers can hide the exact model for privacy, and on laptops the browser may be using the integrated GPU instead of the dedicated one. Set the browser to use the high-performance GPU in your operating system's graphics settings.
What does it mean if a software renderer is listed?
The browser is drawing with the CPU. Turn on hardware acceleration in the browser settings, update your graphics driver and restart the browser.
Is WebGPU required for the tests on this site?
No. Most tests use WebGL 2. Only the compute test needs WebGPU, and it shows a clear message when it is not available.
Is any of this sent to the site?
No. Everything shown is read locally by your browser and stays on your device.
Why is the device memory only approximate?
Browsers round it to protect privacy, and some do not report it at all.
