'''A4-9120C''' is a {{arch|64}} [[dual-core]] ultra-low power [[x86]] mobile microprocessor introduced by [[AMD]] in early [[2019]]. This processor is based on AMD's {{amd|Excavator|Excavator microarchitecture|l=arch}} and is fabricated on a [[28 nm process]]. The A4-9120C operates at a base frequency of 1.6 GHz with a [[TDP]] of 6 W and a {{amd|Turbo Core|turbo}} frequency of 2.4 GHz. This APU supports single-channel DDR4-1866 memory and incorporates {{amd|Radeon R4 series}} graphics operating at up to 600 MHz.
