Apple officially introduced its 2018 line-up of iPhones — the premium iPhone XS, iPhone XS Max and iPhone XR at an event in California late on Wednesday. Both the iPhone XS and XS Max are fueled by Apple’s latest A12 Bionic chipset built on 7-nm design, which allows for 6.9 billion transistors on the chip. Also, there is a new neural engine with an 8-core dedicated machine learning (ML) processor.
