Mac os x processor architecture

The "i7 extreme" CPUs are an exception to this. Wikipedia has excellent tables of model numbers for each microarchitecture. To learn more about the differences between the pipelines of various microarchitectures , see articles like this Ars Technica one about Haswell. Even the Wikipedia articles are not bad. Intel's and AMD's optimization manuals also have some microarchitectural details, but don't always explain their asm optimization suggestions with analysis of how the microarchitecture operates.

This is why I prefer Agner Fog's guide.

NeXTSTEP vs Mac OS X - System Demo and Comparison

On my Linux Core2 system prints: target-cpu core2. I assume it will do something similar on OS X.

System Profiler

You need a new enough version of clang or gcc to recognize your CPU's microarchitecture and map it to a code-name. Another similar approach is to filter the asm output from gcc's -fverbose-asm , which includes the optimization options as comments. I don't know a clang equivalent for this. This works on a Haswell system: see this example on the Godbolt Compiler Explorer. In the Apple menu top left of your screen select About This Mac. And it will tell you the chips details 22nm Haswell i5 U plus also comparisons to the prior and later models.

How to Find Mac Processor Details & CPU Speed via Command Line with sysctl

Even looking up the processor at Intel doesn't give the 'family'. Tetsujin: google x wikipedia and you'll see that it's a Westmere microarchitecture CPU. PeterCordes - for sure. I did actually know it is a Westmere machine, but my main point was that none of the answers so far would tell me that without a little Google-Fu of my own, so don't actually answer the OP's question, per se.

Tetsujin: good point; this is one of those cases where people that know the answer forget that it's not obvious to people that don't. I added an answer that covers step 2. System Profiler Clicking on the button marked System Report On the first page, it will give you more detailed info about your machine, including processor info Terminal I am a fan of Terminal in general. To get the exact CPU model including the microarchitecture number, in Terminal, execute the following command: sysctl -n machdep.

B09 SMC Version system : 2. Allan Allan Out of all the options you provide, only the Terminal method will actually tell you the architecture as requested in the question, unless I'm missing something. Bob Unless I am missing something, I can't seem to spot the architecture in either option.

NumLock Oh, not having the architecture name is to be expected I don't think the CPU actually reports as the code name, so the OS would have to keep an up-to-date database The model number is enough to easily and uniquely identify the architecture, so IMO that counts. But the non-Terminal options here don't even provide the model number; trying to guess which CPU it is and its performance, efficiency, etc. The terminal option is the only useful thing in this answer.

You should remove the other options to not encourage people to give useless answers when people ask them what microarchitecture their CPU has. The model number is great, because you can tell at a glance from the first digit what microarch it is, or google for full details. You still suggest two useless methods that don't tell you the model number, only "i7", and you suggest them first. You don't make it clear that the terminal way is the only one that lets you answer the OP's question. The "About" and "System Profiler" stuff appears to be just a waste of time.

Even worse, the red arrow pointing at "processor info" implies that "Core i7" is a valid answer to the "what microarchitecture do I have" question. It's too bad there isn't a GUI way that gives a satisfactory answer, but there isn't. You can get it from the command-line with sysctl -n machdep. Peter Cordes Peter Cordes 2 2 silver badges 10 10 bronze badges. Also more slightly outdated info here. Interesting and rather novel approach! Question: is gcc or clang something one would expect to find on a non-programmer's Mac?
