'''Ryzen 7 4800U''' is a {{arch|64}} [[octa-core]] high-end performance [[x86]] mobile microprocessor introduced by [[AMD]] in early [[2020]]. Fabricated on [[N7|TSMC's 7-nanometer process]] and based on AMD's {{amd|Zen 2|Zen 2 microarchitecture|l=arch}}, the 4800U operates at a base frequency of 1.8 GHz with a [[TDP]] of 15 W and a {{amd|Precision Boost|boost}} frequency of up to 4.2 GHz. This APU supports up to 64 GiB of DDR4-3200 or up to 32 GiB of quad-channel LPDDR4x-4266 memory. The 4800U integrates {{amd|Radeon Vega 8}} graphics operating at up to 1.75 GHz.

This model supports a configurable TDP-down of 10 W and TDP-up of 25 W.
