## TL;DR

WebGPU is the next-generation graphics and compute API for the web, succeeding WebGL. Based on modern GPU APIs (Vulkan, Metal, Direct3D 12), it provides lower-level access for better performance, compute shaders, and explicit resource management.

## Core Explanation

WebGPU uses `navigator.gpu.requestAdapter()` and separates logical device from physical GPU. It introduces: compute shaders (GPU parallel computation beyond graphics), bind groups (explicit resource binding), render bundles (pre-recorded command lists), and WGSL shading language (replacing GLSL). Browser support: Chrome 113+, Edge 113+, Firefox Nightly, Safari Technology Preview.
