Steve316 Posted February 28, 2008 Share Posted February 28, 2008 Everyone knows that in the latest ver. of mb and mbp apple has installed intel 45nm cpu inside. However, how can we possibly know if the mb/mbp is using the 45nm or 65nm? Is there any method to check in the Mac OS? Link to comment Share on other sites More sharing options...

The 45nm chips have 6MB of L2 cache. That will show up in the System Profiler. Link to comment Share on other sites More sharing options...

But the older chips are always 2mb, or 4mb. The new Macbooks also have slightly different keyboard layouts, that's the only physical change. Otherwise you can also identify them by serial no. or something. Link to comment Share on other sites More sharing options...
MacUser2525 Posted March 1, 2008 Share Posted March 1, 2008 SSE4 instruction set in the profiler as well, I don't believe any 65nm processors have it. Link to comment Share on other sites More sharing options...
