How do i5 mobile and i7 mobile differ?

[ehume]

I am looking at cpu's like i5-3317U with 2 cores and 4 threads, and then seeing cpu's like i7-3517U with 2 cores and 4 threads. Aside from speed, cache size, and minor things, what's different? They don't differ the way an i5 and an i7 desktop chips do.

They look like the same chips with slightly goosed features. Am I missing something big?

Find both chips and compare.

I did that. That's why I know about the number of cores, the number of threads, the speed and the cache size. But again, it's like looking at no difference except the size of features.

Perhaps the only thing that can't be adjusted is cache size. But such a piddling difference between i5 and i7.

Well that's the difference.
