Exynos. Exynos is a series of system on a chip (SoC) semiconductors designed and manufactured by Samsung Electronics for use in its own mobile devices and those of other manufacturers. The processors integrate central processing unit (CPU), graphics processing unit (GPU), memory controller, and image signal processor (ISP) components onto a single die. Initially developed for high-end smartphones, the product line has expanded to include solutions for mid-range phones, tablet computers, and wearable technology.

Overview

The Exynos brand represents Samsung's in-house semiconductor design and fabrication efforts, competing directly with offerings from Qualcomm (Snapdragon), MediaTek, and Apple's Apple silicon in the global mobile market. These SoCs are a critical component of Samsung's vertical integration strategy, allowing control over both hardware and software in devices like the Samsung Galaxy S series. Key technological focuses across generations have included advancements in semiconductor fabrication processes, such as the adoption of FinFET transistors and extreme ultraviolet lithography (EUV), and the integration of dedicated processors for artificial intelligence (AI) and 5G connectivity.

History

The lineage of Exynos processors can be traced to Samsung's earlier S3C and S5P series of application processors used in early smartphones like the Samsung Galaxy S. The first chip to bear the Exynos name was the dual-core Exynos 4210, announced in 2011 and featured in the international version of the Samsung Galaxy S II. Subsequent years saw rapid iteration, with the introduction of the big.LITTLE heterogeneous computing architecture with the Exynos 5 Octa in 2012. A significant shift occurred with the Exynos 8890 in 2015, which featured Samsung's first custom CPU core design, dubbed Mongoose. The company has also formed strategic partnerships, such as with AMD to integrate Radeon graphics IP, beginning with the Exynos 2200.

Architecture and features

Exynos SoCs typically employ CPU clusters based on ARM's Cortex-A series designs, though several generations utilized Samsung's own custom CPU cores for performance tasks. The integrated GPUs have historically been from ARM Mali series or, more recently, AMD RDNA architecture. A defining architectural feature is the inclusion of a dedicated neural processing unit (NPU), such as the one in the Exynos 9820, for on-device AI acceleration. Other standard components include advanced ISPs for computational photography, modems for LTE and 5G NR connectivity co-developed with Samsung's Shannon systems, and security subsystems featuring a dedicated secure element.

Product lineup

The Exynos portfolio is segmented into series targeting different market tiers. The flagship number series, such as the Exynos 2100 for the Samsung Galaxy S21, utilizes the most advanced process nodes and highest-performance cores. The mid-range is served by the Exynos 7, 8, and 9 series, like the Exynos 9611 used in devices like the Samsung Galaxy A51. For wearables, Samsung offers the Exynos W series, powering the Samsung Galaxy Watch. Additionally, the company produces Exynos-branded solutions for specific functions, including the Exynos Auto for automotive infotainment and the Exynos i series for Internet of things (IoT) applications.

Software and development

Software support for Exynos platforms is primarily channeled through Samsung's own One UI software experience and the Android ecosystem. The company provides development resources through the Samsung Developers portal, including board support packages and documentation. Historically, the use of different SoC platforms in otherwise identical Galaxy smartphone models, a practice known as chipset segregation, has presented challenges for the developer community, particularly in the custom ROM and rooting scenes, due to differing device driver and kernel requirements.

Reception and market performance

Critical reception of Exynos processors has been mixed across generations, often compared directly to their Qualcomm Snapdragon counterparts used in other regional variants of the same Samsung phones. Reviews from outlets like AnandTech and GSMArena have frequently noted competitive CPU performance but sometimes lagging GPU efficiency or thermal management. Market performance is intrinsically tied to Samsung's own device sales, though Samsung has also supplied Exynos chips to other manufacturers like vivo and Meizu. The division faces intense competition in the global SoC market, where MediaTek and Qualcomm hold significant market share, prompting strategic shifts in Samsung's foundry and design roadmap.
