even if the processor on the macbook is "faster", it will throttle a lot more times than the mba 11/13 since it has no fan.
IDK if you would like the keyboard of the macbook.
the ssd of the new macbook still hasn't been benchmarked, but ssd is ssd. if you already use an ssd, having a faster ssd will not be very noticeable.
Putting the rest aside, the 2012 MBA doesn't have very good battery life, the improvement in run time came in 2013. The 2012 MBA also doesn't have 802.11ac wifi, so there will be a big speed difference there too. And the 2012 MBA has a much slower SSD. Again, they made a major improvement there in 2013.
Personally I would not be interested in a 2012 MBA, but the 2013 is still a nice machine - no plans to upgrade my 2013 11" i7/8gb/512gb MBA and definitely not interested in the MacBook.
It will not gain you much. It is primarily the processor, not the batteri, which causes 2013 to have better batteri-life than 2012.2012 MBA has the same battery dimension with 2013 version. You could plug 2013 version into 2012 perfectly. I did it, and it runs great.
Its CPU, GPU, and storage performance is in the neighborhood of a MacBook Air from two or three years ago.
