About the AMD Ryzen 9 9955HX CPU

The AMD Ryzen 9 9955HX is a 16-core (32-thread) processor built for the mobile CPU market. It launched in Q1 2025. It is part of AMD's Ryzen 9 lineup, which is based on the Zen 5 microarchitecture. The 9955HX is compatible with AMD Socket FL1 motherboards and is fabricated on TSMC's 4 nm manufacturing process. It features the Radeon 610M integrated graphics solution.

Memory and Cache

The Ryzen 9 9955HX supports DDR5 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Ryzen 9 9955HX has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 80 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 1 MB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 64 MB.

Cores and Clock Speeds

The Ryzen 9 9955HX features 16 total cores which can process 32 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 2.5 GHz, and it can boost up to 5.4 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture. The multiplier is unlocked, enabling overclocking for those seeking to push the CPU's performance further.

Integrated Graphics

The Ryzen 9 9955HX includes an integrated graphics solution called Radeon 610M. This graphics processor is directly integrated into the CPU and is not as powerful as a dedicated graphics card. While integrated graphics can handle basic tasks like web browsing and office applications, it is not suitable for more demanding activities such as gaming or video editing, where a dedicated graphics card offers superior performance.

Benchmark Performance

The Ryzen 9 9955HX has the 6th best 3DMark 11 Performance Physics score among the 767 benchmarked CPUs in our database. It achieves 86.06% of the performance of the best benchmarked CPU, the AMD Ryzen 9 9950X.

About the AMD Ryzen 7 7745HX CPU
