AMD Ryzen 9 9955HX
The AMD Ryzen 9 9955HX is a high-performance Zen 5 mobile processor from the Ryzen 9000HX series (codename Fire Range). It provides 16 cores and 32 threads, a 2.5 GHz base clock and a maximum boost up to 5.4 GHz. The CPU cores are built on TSMC 4 nm FinFET, while the I/O die uses TSMC 6 nm FinFET.
The processor features 16 MB of L2 and 64 MB of L3 cache, supports DDR5-5600 memory (up to 96 GB, dual channel) and PCIe 5.0 (28 native lanes). It integrates AMD Radeon 610M graphics (RDNA 2 architecture, 2 compute units, 2200 MHz). Default TDP is 55 W, with a configurable cTDP range of 55–75 W and a maximum junction temperature (Tjmax) of 100 °C.
The chip targets gaming laptops and mobile workstations. In robotics it can act as a powerful high-level compute unit in x86-based systems, handling perception, planning and data processing.
