I have an Apple M1, Creepjs detect my mac as ARM with is true, but indicate as an Intel CPU.

The userAgentData section gets the real platform, version, and architecture (macOS 12.0.1 arm), and the device section gets metrics that no longer provide updated platform info.

For example, log this to the console

let {
  platform: uaPlatform,
  architecture,
  platformVersion
} = await navigator.userAgentData.getHighEntropyValues(['architecture', 'platform', 'platformVersion'])
let { userAgent, platform } = navigator

console.log('userAgentData:', uaPlatform, platformVersion, architecture)
console.log('navigator: ', /\(([^\)]+)/g.exec(userAgent)[1], platform)

The device section gets metrics from navigator.userAgent and navigator.platform. Starting in Chrome 101, those metrics will be reduced across all platforms.

webgl should get the "Apple M1" chip on macOS Monterey.

gl = new OffscreenCanvas(0,0).getContext('webgl')
ext = gl.getExtension('WEBGL_debug_renderer_info')
renderer = gl.getParameter(ext.UNMASKED_RENDERER_WEBGL)
console.log(renderer)
