'''Exynos 990''' is a {{arch|64}} [[octa-core]] [[ARM]] high performance mobile [[system on a chip]] designed by [[Samsung]] and introduced in [[2020]]. The processor is fabricated on Samsung's [[7 nm process|7nm]] EUV FinFET process and features [[8 cores]] in a tri-cluster configuration consisting of 2 {{samsung|Mongoose 5|l=arch}} [[big cores]], 2 {{armh|Cortex-A76|l=arch}} [[middle cores]], and 4 Cortex-A55 [[little cores]]. This chip supports up to 12 GiB of quad-channel 16-bit LPDDR5-5500 memory and incorporates a {{armh|Mali-G77}} MP11 GPU. The 990 is designed to go along with Exynos Modem 5123 5G modem.<br />
