AMD Ryzen 9 9955HX

AMD R9 9955HX

The AMD Ryzen 9 9955HX is a high-end notebook processor from the Fire Range series with 16 cores and hyperthreading (SMT), which means it can process up to 32 threads simultaneously. Unlike the Ryzen 9 9955HX3D, the chip does not offer a 3D V-Cache. The chip was presented at CES in early 2025 and is intended for fast and expensive gaming laptops.

Thanks to the high-clocked 16 Zen 5 cores, the performance of the CPU should be excellent and only be outperformed by the 9955HX3D thanks to the 3D V-Cache. Together with the Intel Core Ultra 9 285HX at the top of the mobile CPUs.

The 9955HX is intended for large and heavy gaming notebooks and is therefore configurable from 55-75 watts TDP (default 55 watts). The SoC is manufactured in the modern 4nm FinFET process at TSMC (both compute dies, I/O die in 6nm) and should therefore have very good energy efficiency.
