At its ‘By Innovation Only’ event today Apple announced three new iPhones. The iPhones 11, as they’re collectively called are all powered by the A13 chip, as Apple once again differentiates two of its smartphones from the third on the basis of display material and camera specifications. As opposed to previous iPhone launches, this time the A13 was introduced by the executive in charge of designing the processor. As a result, we’ve got some juicy details for the chip that you should be interested in. Take a look below for more.

Apple’s A13 is the first chip from the company that’s manufactured on TSMC’s last iteration of the 7nm process node. This node, dubbed as the N7+ uses Extreme Ultraviolet light for lithography. The light has a shorter wavelength than traditional fabrication and as a result, it allows the fab to etch finer circuits on silicon.
