'''Exynos 9820''' is a {{arch|64}} [[octa-core]] [[ARM]] high performance mobile [[system on a chip]] designed by [[Samsung]] and introduced in early [[2019]]. The processor is fabricated on Samsung's [[8 nm process|8nm]] [[8LPP|LPP (Low Power Plus)]] FinFET process and features [[8 cores]] in a tri-cluster configuration consisting of 2 {{samsung|Mongoose 4|l=arch}} [[big cores]] and 2 {{armh|Cortex-A75|l=arch}} [[middle cores]] and 4 Cortex-A55 [[little cores]]. This chip supports up to 12 GiB of quad-channel 16-bit LPDDR4X-3600 memory and incorporates a {{armh|Mali-G76}} MP12 GPU. The 9820 incorporates an LTE modem supporting cat 20 download and upload.
