WebGPU: How the W3C's New Web Standard Replaces WebGL for GPU Computing

WebGPU is a new W3C standard that gives web applications direct access to modern GPU capabilities for both graphics rendering and general-purpose parallel computation. Unlike WebGL, which is based on the older OpenGL ES programming model and relies on a global state machine, WebGPU uses explicit pipelines, recorded command buffers, and a browser-specific shader language called WGSL. The architectural shift means developers must write more setup code, but the GPU and browser receive richer information before rendering begins, enabling more efficient execution. WebGPU also introduces first-class compute shaders, a feature absent from WebGL, allowing the GPU to handle non-graphics workloads such as physics simulation and data processing. While WebGL continues to power much of the interactive 3D web through frameworks like Three.js and Babylon.js, WebGPU is designed to meet the demands of modern GPU architectures that existing web graphics APIs could not efficiently address.
