The GPUAdapter interface of the WebGPU API represents a GPU adapter. From this you can request a GPUDevice, adapter info, features, and limits.

A GPUAdapter object is requested using the GPU.requestAdapter() method.

Instance properties

features Experimental Read only: A GPUSupportedFeatures object that describes additional functionality supported by the adapter.
isFallbackAdapter Experimental Read only: A boolean value. Returns true if the adapter is a fallback adapter, and false if not.
info Experimental Read only: A GPUAdapterInfo object containing identifying information about the adapter.

requestDevice() Experimental: Returns a Promise that fulfills with a GPUDevice object, which is the primary interface for communicating with the GPU.

Examples

async function init() {
  if (!navigator.gpu) {
    throw Error("WebGPU not supported.");
  }

  const adapter = await navigator.gpu.requestAdapter();
  if (!adapter) {
    throw Error("Couldn't request WebGPU adapter.");
  }

  const device = await adapter.requestDevice();
