As far as internal specs are concerned, the MacBook Pro is an easy winner as compared to the MacBook Air. The MacBook Pro is powered by a 2.4 GHz, dual core Intel Core i5 processor. It packs in 4 GB RAM cache, Intel Iris Graphics and an option to select from 512 GB, 256 GB, or 128 GB solid-state drive. The 13-inch Macbook Pro is indeed a powerhouse able to handle virtually anything that you challenge it with. If you are someone who lives out of the suitcase and travel a lot, then the MacBook Air is an ideal one for you and a perfect travel companion. The 13-inch and the 11-inch MacBook Air weight 3 pounds and 2.4 pounds respectively. The 15-inch Air is one pound heavier than the 13-inch one. The MacBook Air is a lot slim as compared to the MacBook pro. Both the 11-inch and the 13-inch MacBook Air are only 0.68 inches thick while the Pros are thick at 0.71 inches. Though the latest MacBook Pros may be slightly bigger and heavier than the MacBook Airs, but the MBPs clearly beat their lightweight mates in the display department. The MBPs offer rich and sharp details as compared to the Airs.
