Does system profiler indicate what processor you have?

[Joko]

I'm trying to find out if I am working on a Merom or Penryn processor. It's a 2.6Ghz, but I can't find out which one it is? In the system profiler it says 4MB L2 cache, does this indicate what processor it is?

Thanks alot

4MB L2 Cache - is Merom i believe, as the Penryn has 3MB.

I may be wrong, but i think that's correct.

More likely the model identifier would be a better tell.

http://developer.apple.com/documentation/HardwareDrivers/AppleHardware-date.html

You'll see the newest ones will be looking for this.

Clicking on the newest MacBook document, and into the info on that machine will find a line like this.

"The value of the 15-inch MacBook Pro model identifier string is MacBookPro4,1."

for the MacBook Pro.

Just can match your model to the right document and it will tell you what is inside it. As far as Apple deems to make that info public.

Edit: this info shows up in About this Mac.

Edit Again: more general link.

Actually, if it's 2.6GHz, then a 4MB L2 Cache is Merom, because the 2.6GHz Penryn has a 6MB L2 Cache. The 2.4GHz Penryn is the only one that got an L2 cache reduction.
