Report: Apple working expanding use of ARM chips in Macs


By

The new MacBook Pro with TouchBar utilize a dedicated ARM processor to run the TouchBar. It's described as basically an Apple Watch embedded in the Mac. A recent report suggests that Apple is looking to add additional ARM chips to help with battery life.

Bloomberg:

Apple engineers are planning to offload the Mac's low-power mode, a feature marketed as "Power Nap," to the next-generation ARM-based chip. This function allows Mac laptops to retrieve e-mails, install software updates, and synchronize calendar appointments with the display shut and not in use. The feature currently uses little battery life while run on the Intel chip, but the move to ARM would conserve even more power,
