How to get CPU frequency in c#
var searcher = new ManagementObjectSearcher(
"select MaxClockSpeed from Win32_Processor");
foreach (var item in searcher.Get())
{
var clockSpeed = (uint)item["MaxClockSpeed"];
}
if you wish to get other fields look at class Win32_processor
Try this code
using System.Management;
uint currentsp , Maxsp;
public void CPUSpeed()
{
using(ManagementObject Mo = new ManagementObject("Win32_Processor.DeviceID='CPU0'"))
{
currentsp = (uint)(Mo["CurrentClockSpeed"]);
Maxsp = (uint)(Mo["MaxClockSpeed"]);
}
}
If you want to get the turbo speed, you can make use of the "% Processor Performance" performance counter and multiply it with the WMI "MaxClockSpeed" as follows:
private string GetCPUInfo()
{
PerformanceCounter cpuCounter = new PerformanceCounter("Processor Information", "% Processor Performance", "_Total");
double cpuValue = cpuCounter.NextValue();
Thread loop = new Thread(() => InfiniteLoop());
loop.Start();
Thread.Sleep(1000);
cpuValue = cpuCounter.NextValue();
loop.Abort();
foreach (ManagementObject obj in new ManagementObjectSearcher("SELECT *, Name FROM Win32_Processor").Get())
{
double maxSpeed = Convert.ToDouble(obj["MaxClockSpeed"]) / 1000;
double turboSpeed = maxSpeed * cpuValue / 100;
return string.Format("{0} Running at {1:0.00}Ghz, Turbo Speed: {2:0.00}Ghz", obj["Name"], maxSpeed, turboSpeed);
}
return string.Empty;
}
The InfiniteLoop method is simply an integer that gets 1 added and subtracted:
private void InfiniteLoop()
{
int i = 0;
while (true)
i = i + 1 - 1;
}
The InfiniteLoop method is just added to give the CPU something to do and turbo in the process. The loop is allowed to run for a second before the next value is taken and the loop aborted.
