quad core, hyperthreading and 15W TDP. sounds like what you want. look for laptops with that chip. 
 
seems about equal to last gen's 7700HQ, which was 45W TDP.

i have kinda big hands too, and i use a 15" MacBook Pro. it's nice to have a place for my wrists. if you have the chance to use a 13" laptop for a little bit, maybe ask a friend or something, try to find out if you can have your hands and wrists in a comfortable position for typing on a 13"... if you can't just get a 15". 
 
i can't really give you recommendations on specific laptops, because i'm not too familiar with them as well.
