Question

I need to get any information about the CPU/GPU/memory.The number of cores, memory value, memory and cpu usage... I found a way to do this for IE:How to Use JavaScript to Find Hardware Information

solutions for other browsers I do not know. Any idea how to do it? maybe webgl has access to information about your computer? or flash? or any other technology?

非常感谢

该守则将印刷万国邮联的图象,其中将列出你能够拥有的该浏览器性能目标的所有信息(管理局没有标准,因此每个浏览器都有改动)。

<html>

<body>
  <canvas id="glcanvas" width="0" height="0"></canvas>
  <script>
    var performance = window.performance || window.mozPerformance || window.msPerformance || window.webkitPerformance || {};

    document.write("<br>");
    for (var value in performance) {
      document.write(value + "<br>");
    }

    document.write("<br><br><br>");

    var canvas;
    canvas = document.getElementById("glcanvas");
    var gl = canvas.getContext("experimental-webgl");

    document.write(gl.getParameter(gl.RENDERER) + "<br>");
    document.write(gl.getParameter(gl.VENDOR) + "<br>");
    document.write(getUnmaskedInfo(gl).vendor + "<br>");
    document.write(getUnmaskedInfo(gl).renderer + "<br>");


    function getUnmaskedInfo(gl) {
      var unMaskedInfo = {
        renderer:   ,
        vendor:   
      };

      var dbgRenderInfo = gl.getExtension("WEBGL_debug_renderer_info");
      if (dbgRenderInfo != null) {
        unMaskedInfo.renderer = gl.getParameter(dbgRenderInfo.UNMASKED_RENDERER_WEBGL);
        unMaskedInfo.vendor = gl.getParameter(dbgRenderInfo.UNMASKED_VENDOR_WEBGL);
      }

      return unMaskedInfo;
    }
  </script>

CPU速度估算,按时间计算,计算可变数数百万倍:

const runs = 150000000;
const start = performance.now(); // in ms, usually with 100us resolution
for (let i = runs; i>0; i--) {}
const end = performance.now();
const ms = end - start;
const cyclesPerRun = 2;
const speed = (runs * cyclesPerRun) / ms / 1000000;
console.log(`Time: ${Math.round(ms)/1000}s, estimated speed: ${Math.round(speed*10)/10} GHz`);

。更有指示,它们可能更快地增加频率等。视您的工作情况而定,你可能最好使用<条码>runs /ms作为通用的“CPUpac”参数,而不是试图用<条码>估算GHz的锁速。

您也可通过在万国邮联上操作上述代码,估算<代码>的周期代码>。

const knownSpeed = 3.2; // GHz
const estimatedCyclesPerRun = knownSpeed / (runs/ms/1000000);
console.log("cyclesPerRun = " + estimatedCyclesPerRun);

这一基准还取决于用户开放的浏览器数量,或者如果其他一些方案(如视频游戏)已经使用计算机资源等。
