The MacBook uses the energy-efficient Intel Core M processor. However, the Core M processors do not perform as well as the Intel Core i5 / i7 processors currently used in the MacBook Air.
For the average user, the speed difference won’t be a hindrance, but for those who want to multitask apps like Photoshop and iMovie, the slowness will be even greater.
Color
The MacBook Air is available in silver only, but the new MacBook is available in the same colors as the iPhone, iPad, and Apple Watch. If you wish, you can use your MacBook on your phone or tablet. Available in Gold, Rose Gold, Space Gray, Silver, etc. depending on the color of the tablet and watch.
