GPU detection explained.
GPU detection in the browser uses the WEBGL_debug_renderer_info extension, which exposes the GPU vendor and renderer strings. This is the same data WebGL uses to select rendering optimizations.
For detailed GPU specifications including VRAM, clock speeds, and driver version, use GPU-Z (Windows), System Information (macOS), or lshw (Linux).
FAQ
Common questions.
Some browsers block the WEBGL_debug_renderer_info extension for privacy. Try Chrome or Firefox which typically expose this data.
WebGL (Web Graphics Library) is a JavaScript API for rendering 2D and 3D graphics in the browser without plugins, using your GPU for hardware acceleration.
No — browsers do not expose VRAM (video memory) information. This can only be read at the OS level or via GPU-specific software.
Our GPU tier system estimates performance from 1 (basic/integrated) to 5 (flagship gaming/workstation) based on the renderer string. It's an approximation, not a benchmark.
