I5 3rd Gen vs I5 4th Gen

[Drackeo]

Hey im looking at buying a new laptop to use for school. I was looking at the Lenovo Yoga series. Ive found several great deals on them off of ebay. But ive seen modles that are exactly the same except for the processor and price. So i can get a Yoga Pro 2 13.3" for about $300 with the 3rg Gen i5-3337U processor. But i found the exact same laptop for $70 more with the 4rth Gen i5-4210u. Will there be a very noticeable difference in performance? Im planning on doing some coding on it, not much gaming.

There is not much difference I would go with the cheaper of the 2.

4th gen introduced some pretty good power saving features over 3xxx  I would go for 4xxx series

Almost no difference in performance, but some improvements in power consumption. If you really care about battery life, go with 4th gen.

Mostly in sleep mode, but a bit in usage as well. Depends on how important it is to OP whether it'd be worth $70(?)
