as posted by the channel

iPhone Air was the big star unveiled by Apple in early September, but inside was another hardware set launched that day: three new custom Apple microchips. Apple’s A19 Pro SoC prioritizes AI workloads with neural accelerators added to the GPU cores. Replacing Broadcom and Qualcomm parts is the N1 and C1X, Apple’s first iPhone networking chip and second generation iPhone modem. CNBC sat down with three Apple executives for the first U.S. interviews about its move to control all core iPhone chips.
