The following measure the CPU performance speed. mostly accurate on mobile rather than desktop.

var _speedconstant = 4.5e-9; //if speed=(c*a)/t, then constant=(s*t)/a and time=(a*c)/s
var d = new Date();
var amount = 150000000;
var estprocessor = 1.7; //average processor speed, in GHZ
console.log("JSBenchmark by Aaron Becker, running loop "+amount+" times.     Estimated time (for "+estprocessor+"ghz processor) is "+(Math.round(((_speedconstant*amount)/estprocessor)*100)/100)+"s");
for (var i = amount; i>0; i--) {} 
var newd = new Date();
var accnewd = Number(String(newd.getSeconds())+"."+String(newd.getMilliseconds()));
var accd = Number(String(d.getSeconds())+"."+String(d.getMilliseconds())); 
var di = accnewd-accd;
//console.log(accnewd,accd,di);
if (d.getMinutes() != newd.getMinutes()) {
di = (60*(newd.getMinutes()-d.getMinutes()))+di}
spd = ((_speedconstant*amount)/di);
console.log("Time: "+Math.round(di*1000)/1000+"s, estimated speed: "+Math.round(spd*1000)/1000+"GHZ");

This depends on browser tabs, memory use, etc. but pretty accurate when running it at first, say at the loading of a page.
