OMG communication is hard, apperantly. And interesting.
Intels mobile naming scheme is not complicated when you learn of it. People in general don't care much though, so they are most definitely confused about it. A friend worked in an electronic shop and they marketed the i3, i5 and i7 as having three, five and seven cores respectively.
AMD has so far been much worse with their APU naming though, and do not forget AMD has no equivalent to the frankly excellent Intel Ark so it's super annoying to read up on those parts, let alone trying to find out what kind of performance you can expect, especially from the IGP. And honestly namning these things so that avarage joes clearly understands the parts they're purchasing is a fools game anyway.
