How Do I Test My Processor Speed?
A computer central processing unit or CPU is the brain of a computer. The calculations necessary to make a computer run are carried out by the CPU. When you purchase a computer, the CPU type and speed is normally one of the primary technical specifications listed, but when you actually run your PC, the CPU may not run at the exact speed that the processor is rated to run at. There are several freeware diagnostic tools that allow you to test exactly how fast the CPU is actually running.
Things You'll Need
- A freeware CPU speed tester
Using CPUInfo to Test CPU Speed
Go to the CPUInfo download site (First resource link at the bottom of this page.).
Click the "download cpuinfo.exe" link on the page to download the program. No installation is necessary.
Open the downloaded .exe file; a colored pinwheel will spin as the test is carried out and your CPU speed will be displayed in large numbers in terms of megahertz.
Using CPU-Z to Test CPU Speed
Go to the CPU-Z download site (See "Resources" below).
Click on one of the download files for the program on the left-hand side of the screen that is labeled as "No install."
Open CPU-Z.exe after the file download is complete and then check the the number next to the information field called "Core Speed." This will list your current CPU speed in megahertz.
Using CPUSpeed to test a CPU
Go to the Wizard software's download site for their CPUSpeed diagnostic program (See "Resources" section)
Click the link called "Download Here" to being downloading the program. Like the other two tools mentioned above, this program does not require installation.
Open cpuspeed.exe when the download is finished, then click "Test my Speed," and wait several seconds as the CPU speed is tested. Window will appear displaying your tested CPU speed in megahertz.
Tips & Warnings
- CPU-Z displays other useful information beside tested CPU speed such as information about your RAM and motherboard.
