Located under the DRAM chip on the main board, the AP are packaged using PoP technology. The Apple A10 can be found in the iPhone 7 series. The HiSilicon Kirin 955 can be found in the Huawei P9 and the Samsung Exynos 8 as the Qualcomm Snapdragon 820 can be found in the Samsung Galaxy S7 series depending on the world version (US and Asia for the Snapdragon and International for the Exynos).
In this report, we highlight the differences and the innovations of the packages chosen by the end-user OEMs. Whereas some AP providers like for HiSilicon or Samsung choose to consider conventional PoP with embedded land-side capacitor (LSC), others like Apple or Qualcomm use innovative technologies like Fan-Out PoP and silicon based Deep Trench LSC or embedded die packaging with advanced PCB substrate. The detailed comparison between the four players will give the pros and the cons of the packaging technologies.
This report also compares the costs of the different approaches and includes a detailed technical comparison between the packaging structure of the Qualcomm Snapdragon 820, the Samsung Exynos 8, the HiSilicon Kirin 955 and the Apple A10.
