Procs And Comms
The largest component on the front side of the communications board is Apple's new A6 processor, which doubles the number of application cores (to four), yet at $17.50, it costs just $2.50 more than that of the iPhone 4S' processor. But, we'll discuss more on the A6 later. Moving left, the blue-colored part is the Qualcomm MDM9615 4G LTE radio, and the green chip next to that is Qualcomm's RTR8600 GSM/CDMA 3G part, which also handles some LTE duties. Together these two parts cost $34 compared with $23.50 for the non-LTE 4S. Other components shown include a touchscreen controller from TI (purple), Broadcom's touchpad chip (orange) and STMicroelectonics' three-axis accelerometer.
