'''Athlon 300U''' is a {{arch|64}} [[dual-core]] value [[x86]] mobile microprocessor introduced by [[AMD]] in early [[2019]]. This processor is based on AMD's {{amd|Zen+|Zen+ microarchitecture|l=arch}} and is fabricated on a [[12 nm process]]. The 300U operates at a base frequency of 2.4 GHz with a [[TDP]] of 15 W and a {{amd|Precision Boost|Boost}} frequency of 3.3 GHz. This APU supports up to 32 GiB of dual-channel DDR4-2400 memory and incorporates {{amd|Radeon Vega 3}} Graphics operating at up to 1 GHz.
