After years of development, the Chrome team ships WebGPU which allows high-performance 3D graphics and data-parallel computation on the web.
This initial release of WebGPU is available on ChromeOS, macOS, and Windows. Support for other platforms is coming later this year.
A new dawn for web graphics
This initial release of WebGPU serves as a building block for future updates and enhancements. The API will offer more advanced graphics features, and developers are encouraged to send requests for additional features. The Chrome team also plans to provide deeper access to shader cores for even more machine learning optimizations and additional ergonomics in WGSL, the WebGPU Shading Language.
WebGPU is the result of a collaborative effort by the W3C's "GPU for the Web" Community Group, which includes contributions from major companies such as Mozilla, Apple, Intel, and Microsoft. After six years of development (90 contributors, 2000 commits, 3000 issues), from the initial design in 2017, the first implementation is now available in Chrome, with support for Firefox and Safari in progress.
Both the Dawn library for Chromium and the wgpu library for Firefox are available as standalone packages, and they offer great portability and ergonomic layers that abstract OS GPU APIs. Using these libraries in native applications also makes it easier to port to WASM through Emscripten and Rust web-sys.
This initial release of WebGPU is available in Chrome 113 on ChromeOS devices with Vulkan support, Windows devices with Direct3D 12 support, and macOS. Linux, Android, and expanded support for existing platforms will come soon.
Many widely used WebGL libraries are already in the process of implementing WebGPU support or have already done so. This means that using WebGPU may only require making a single line change:
- Babylon.js has full WebGPU support already.
- PlayCanvas announced initial WebGPU support.
- TensorFlow.js supports WebGPU-optimized versions of most operators.
- Three.js WebGPU support is underway, see examples.
WebGPU is a significant technology, and we recommend the following resources to learn more:
- Check out the W3C specifications for WebGPU and WGSL.
- Experiment with samples and explore WGSL with a tour.
- Look at the MDN documentation.
- Read the official explainer and best practices.
- Learn about GPU compute and more.
Many thanks to all Chromium contributors and especially to Intel folks for their invaluable support in making this possible.
