Overview

• AOOSTAR introduced what it calls the first motherboard-with-processor platform to ship with AMD’s Ryzen 9 9955HX3D and 9955HX mobile flagships.
• Both CPUs feature 16 cores and 32 threads with boost clocks up to 5.4 GHz and a 55W TDP configurable to 75W, with the 9955HX3D adding large 3D V-Cache.
• The M-ATX board includes a 10-phase VRM, PCIe 5.0 x16 for GPUs, two Gen5 x4 M.2 slots, and two DDR5 UDIMM slots supporting up to 128GB.
• The processor arrives pre-attached under a vapor-chamber IHS cover, and the board retains the AM5 mounting system for broad cooler support.
• China pricing is set at 4,799 RMB for the 9955HX3D bundle and 3,799 RMB for the 9955HX, with coverage noting the higher-end option undercuts AMD’s desktop 9950X3D CPU alone; AOOSTAR has not detailed wider availability.
