How to Check the Mac Processor Speed
Want to know how fast a Mac is? You can check a Macs processor speed a few different ways, but here are two methods: super easy through the GUI, and a more advanced way through the command line.
Check a Mac CPU the Easy Way: GUI
Go up to the Apple menu and select “About This Mac”:
You will then get a window that shows what version of Mac OS X you are running, what your processor and processor speed is, and how much memory your Mac has.
If you want, you can then go through and check CPU usage through the Mac Task Manager, known as the Activity Monitor.
Check a Macs CPU the Fun Way: Command Line
The GUI is easy, but what fun is that? What if you want to check a machines processor remotely through ssh? Let’s use the Terminal instead.
Using the following command you can check what the CPU is:
The string returned includes both the brand and the clock speed of your Macs processor. For example, you might see:
machdep.cpu.brand_string: Genuine Intel(R) CPU T2500 @ 2.00GHz
Keeping with the theme here, you may then want to monitor what your Mac CPU is doing. If you want a command line activity monitor, use this variation of the ‘top’ command to monitor CPU usage. I like it better than the standard top command because it uses less CPU itself, and it sorts processes by their CPU usage. Give it a go.
