Samsung Exynos
Overview
Samsung Exynos (삼성 엑시노스) is a brand of mobile application processors (AP) developed by Samsung Electronics' System LSI Business. First launched in 2011, it has been primarily used in Samsung's flagship smartphones such as the Galaxy S series and Galaxy Note series, and has recently expanded into mid-range models, wearables, and automotive semiconductors. Exynos is based on the ARM architecture and is a system-on-chip (SoC) integrating custom-designed CPU cores, GPU, ISP, NPU, and more.
Main Content
History and Development
- Early (2011–2014): Starting with the Exynos 4210 (Galaxy S2), the Exynos 5420 (Galaxy S4) introduced the ARM big.LITTLE architecture.
- Mid (2015–2019): The Exynos 7420 (Galaxy S6) was the first to apply a 14nm FinFET process, and the Exynos 8890 (Galaxy S7) featured the custom CPU core 'Mongoose'.
- Recent (2020–2024): The Exynos 2100/2200 (Galaxy S21/S22) introduced the AMD RDNA2-based GPU 'Xclipse', and the Exynos 2400 (Galaxy S24) features a 10-core CPU and enhanced AI performance.
Technical Features
- CPU: Mix of ARM Cortex-X, Cortex-A series and custom Mongoose cores (in some models). The Exynos 2400 uses a 1+2+3+4 cluster structure.
- GPU: AMD RDNA2 architecture-based Xclipse GPU supporting ray tracing (from Exynos 2200 onward).
- NPU: AI accelerator for on-device AI features (Galaxy AI).
- ISP: Supports up to 200MP cameras and multi-frame noise reduction.
- Modem: Supports 5G Sub-6GHz and mmWave, Wi-Fi 7, Bluetooth 5.3.
Key Models
- Flagship: Exynos 2200 (Galaxy S22), Exynos 2400 (Galaxy S24), Exynos 2500 (expected 2025).
- Mid-range: Exynos 1380 (Galaxy A54), Exynos 1480 (Galaxy A55).
- Entry-level: Exynos 850, Exynos W920 (wearable).
Competitors and Comparison
- Qualcomm Snapdragon: Often rated lower in GPU performance and power efficiency compared to equivalent models. The Exynos 2400's multi-core CPU performance is close to the Snapdragon 8 Gen 3, but the GPU still lags.
- MediaTek: Strong in the mid-range market; Exynos maintains a flagship image.
- Apple A Series: Significant gap in single-core performance and GPU.
Strengths and Weaknesses
- Strengths: Vertical integration using Samsung Foundry process, graphics potential with AMD GPU, integrated AI features.
- Weaknesses: Heating and power efficiency issues (especially Exynos 2200), lower GPU performance compared to competitors, Geekbench score controversies in some models.
Latest Trends
As of 2024–2025, Samsung Exynos is undergoing the following changes:
- Exynos 2500: Expected to use a 3nm GAA (Gate-All-Around) process, with ARM Cortex-X5 CPU and AMD RDNA3+-based Xclipse 1000 GPU. May be partially used in the Galaxy S25 series.
- Foundry Strategy: Samsung Foundry is improving 3nm process yield; the Exynos 2500 is planned for production on its own process.
- Galaxy AI Integration: From the Exynos 2400, on-device AI features (real-time translation, photo editing) are enhanced, with more advanced AI assistant support expected by 2025.
- Mid-range Expansion: Mid-range models like the Exynos 1480 are used in the Galaxy A series to reduce dependence on Qualcomm.
- Automotive: Exynos Auto V920 (infotainment) and Exynos Auto T5123 (telematics) have been released, supplied to Hyundai Motor and others.
- Intensified Competition: Performance competition against Qualcomm Snapdragon 8 Gen 4 (2025) and MediaTek Dimensity 9400 (2025); Samsung aims to differentiate with its own chips.
