Exynos, formerly Hummingbird, is a series of ARM-based system-on-chips developed by Samsung Electronics' System LSI division and manufactured by Samsung Electronics' Foundry division. It is a continuation of Samsung's earlier S3C, S5L and S5P line of SoCs.
Exynos is distinct from the competing Qualcomm SoCs, but shares similarities to other SoCs offered by MediaTek and Huawei, particularly noting its identical CPU and GPU configuration for most of the recent models.
