'''Ryzen 9 4900H''' 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]] based on AMD's {{amd|Zen 2|Zen 2 microarchitecture|l=arch}}, the 4900H operates at a base frequency of 3.3 GHz with a [[TDP]] of 45 W and a {{amd|Precision Boost|Boost}} frequency of up to 4.4 GHz. This APU supports up to 64 GiB of DDR4-3200 or up to 32 GiB of quad-channel LPDDR4x-4266 memory. The 4900H integrates a {{amd|Radeon Vega 8}} Graphics operating at up to 1.75 GHz.

This model supports a configurable TDP-down of 35 W and TDP-up of 54 W.

The {{\\|4900HS}} is a lower-power version of this processor, featuring slightly lower base and turbo frequencies.
