If you are running macOS, you can determine the processor type and speed by following the steps below. The Windows 8 computer has an 'Intel(R) Core(TM) i7-2600 CPU 3.40 GHz 3.40 GHz.' Intel is the processor brand, Core i7-2600 is the processor model, and 3.40 GHz is the processor speed. For newer versions of Windows, it also displays the System type, like ' 64-bit Operating System, on 圆4-based processor' in the Windows 8 example. In the System properties window, the manufacturer of the processor (e.g., Intel or AMD), the model of the processor (e.g., Core 2), and the speed (e.g., 1.86 GHz) are displayed.
Doing so opens a System window similar to one of the examples below.
If you are running Microsoft Windows, you can determine the processor brand, model or type, and speed by pressing the Windows key and Pause at the same time.
