Exynos

The Samsung Exynos (stylized as SΛMSUNG Exynos),^[1] formerly Hummingbird (Korean: 엑시노스), is a series of ARM-based system-on-chips developed by Samsung Electronics' System LSI division and manufactured by Samsung Foundry. It is a continuation of Samsung's earlier S3C, S5L and S5P line of SoCs.

The first debut of Samsung's indigenously developed SoC is Samsung Hummingbird (S5PC110/111), later renamed as Exynos 3 Single 3110. Samsung announce it on July 27, 2009. In 2011, Samsung announced Exynos 4 Dual 4210 that was later equipped on Samsung Galaxy S II. Since then, Samsung has used Exynos as a representative brand name of their SoC, based on ARM Cortex cores. In 2017, Samsung launched their proprietary ARM ISA-based customized core designs, codenamed "Exynos M". Exynos M series core made a debut with Exynos M1 nicknamed "Mongoose", which was used for Exynos 8 Octa 8890. The Exynos M-series have been implemented throughout the flagship lineup of Samsung Exynos 9 series, until Exynos 990. From 2021 onwards, Exynos M6 and M7 microarchitecture developments have been cancelled and instead Samsung adopts ARM Cortex-X core series as the primary core.^[2]

In 2022, Samsung started adoption of AMD RDNA GPU microarchitecture into their SoC, beginning on Exynos 2200 with Xclipse 920, which used customized "mobile RDNA" based on RDNA 2. In 2024, Samsung expanded AMD RDNA 3-based GPU into their midrange chips, since Exynos 1480 (Xclipse 540).
