Performance
Varients of Intel's 4th Generation Core (Haswell) chipset are used to power all MacBooks.
The latest Airs have received a minor performance boost over the previous generation but are still designed for basic tasks. The Pro series is capable of handling taxing applications like video editing and design.
MacBook Air - Now available with a choice between a 1.4GHz dual-core Core i5 processor or dual-core i7. RAM is configurable up to 8GB and the maximum storage size offered is a 512GB SSD. Basic graphics are provided by an integrated Intel HD 5000 chip. There is no option for a discrete card here, so this is not the machine for graphically intense applications.
MacBook Pro w/Retina Display - The Pro series offers more grunt. The base 13in machine is powered by a 2.4GHz dual-core i5 processor, and is configurable to a dual-core i7 chip running at 2.8GHz.
The 15.4in model is powered by 2GHz, 2.3GHz or 2.6GHz chips. These are all quad-core i7 processors.
RAM is configurable up to 16GB and a maximum of 1TB SSD can be installed in these machines. The standard built-in graphics are Intel's flagship Iris Pro range and it's possible to request an Nvidia GeForce GT 750M with 2GB of GDDR5 memory in the 15in model.
