WebGPU
WebGPU is a web standard that provides high-performance graphics and compute capabilities, enabling developers to run complex operations directly in the browser.

When to use it
Use WebGPU when you need to perform high-performance graphics and compute operations directly in a web browser without relying on server-side processing. WebGPU enables complex tasks like real-time 3D rendering and in-browser machine learning by leveraging the GPU for things like physics simulations or neural network inference.
Quick example
In a web-based game using Babylon.js, you want to render complex 3D scenes with real-time lighting and shadows. By enabling WebGPU in your browser, the game can access advanced GPU features, providing smoother graphics and faster frame rates compared to WebGL. Babylon.js integrates WebGPU as an option for rendering, making it the technology that powers these enhanced graphical capabilities.

Misconceptions
| Misconception | Rebuttal |
|---|---|
| WebGPU replaces WebGL | WebGPU is an alternative, not a replacement. |
| It's only for graphics | WebGPU also handles compute tasks. |
| All browsers support it | Support varies; check compatibility tables. |
Trade-offs
- Performance — requires modern hardware support
- Compatibility — not all browsers support WebGPU
- Complexity — more intricate API than WebGL
