Performance

Under the hood, the Galaxy S21 5G is powered by the Exynos 2100 processor in international markets, while regions such as the USA and China enjoy the Qualcomm Snapdragon 888 5G processor. Both chipsets are built on a 5 nm process, delivering high efficiency and outstanding performance. Coupled with 8GB of RAM, the device handles multitasking with ease, from running demanding applications to delivering a seamless gaming experience.
