I have two Ivy Bridge mobile processors in an anti-static bag, each in a clamshell case. I need to know which is which. I looked at the tops expecting to find a model #, but no, all I found are a few alphanumeric strings. Then I searched for the datasheet for mobile Ivy Bridge, but pages 11-26 with a table of SKUs are missing (see below URL). Would someone please tell me how to distinguish between i5-3340M and i5-3380M?

Also, for future note, you can enter the spec code you find on the processor into the search box here, and it will tell you what processor you have:
