Software can run the CPUID instruction with the right parameters to copy the string into registers. The CPU has its own model number string built in. It responds back with Model Identifier: iMac13,2 system_profiler SPHardwareDataType | grep Identifier So, if you needed your CPU or more commonly, your Model Identifier, you can use the same command coupled with grep. Hardware UUID: XXXXXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXX Serial Number (system): XXXXXXXXXXXXXXXXXXX
Just for reference, you can use the Terminal command: system_profiler SPHardwareDataTypeĪnd get a result that looks just like the screen that I posted in the second section, System Profiler: Hardware Overview: You can then do a search for i7-3770 and pull up the code name and specs. For instance, on my iMac, it the command above responds with: You will get the exact processor that you are using. To get the exact CPU model including the microarchitecture number, in Terminal, execute the following command: sysctl -n _string Pretty much everything you see in the GUI in OS X can be accessed quicker and more accurately through the command line, IMHO. On the first page, it will give you more detailed info about your machine, including processor info (green arrow) you get a complete profile of your system. Your processor will be listed here.Ĭlicking on the button marked System Report.
You will get a screen that gives you an overview of your system. You can "jump" to the section that applies to you.Ĭlicking on the Apple symbol at the top of your screen, select About this Mac So, to answer this question, I am going to provide three methods to find out what CPU you have, the first two, which should be good for most users, and a third method in which you can determine the microarchitecture number so you can look it up on Intel's support site. It's a marketing convention, not a technical one.įor a list of all Intel Processors and their codenames, architectures and specs, Wikipedia's List of Intel Microprocessors has a good page. Contrast that with Apple, the marketing department chooses to actively market the code names of their operatings systems (Mavericks, Yosemite, El Capitan). First off, you are not going to get the processor microarchitecture name (Broadwell, Sandy Lake, Ivy Bridge, etc.) because it's not a prominent branding scheme for the Intel processors.
