AMD EPYC 7601 vs AMD Ryzen 9 9955HX3D

The AMD EPYC 7601 is a 32-core (64-thread) processor built for the server CPU market. It launched in Q2 2017. It is part of AMD's EPYC lineup, which is based on the Zen microarchitecture. The EPYC 7601 is compatible with AMD Socket SP3 motherboards and is fabricated on GlobalFoundries's 14 nm manufacturing process.

Memory and Cache

The EPYC 7601 supports DDR4 memory and features a octa-channel memory controller, allowing it to utilize 8 memory modules simultaneously. In terms of cache, the EPYC 7601 has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 96 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 512 KB, 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 EPYC 7601 features 32 total cores which can process 64 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 2.2 GHz, and it can boost up to 3.2 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 EPYC 7601 does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.

The AMD Ryzen 9 9955HX3D 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 9955HX3D 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 9955HX3D 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 9955HX3D 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 128 MB.

Cores and Clock Speeds

The Ryzen 9 9955HX3D 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 9955HX3D 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 9955HX3D has the 4th best 3DMark 11 Performance Physics score among the 791 benchmarked CPUs in our database. It achieves 89.23% of the performance of the best benchmarked CPU, the AMD Ryzen 9 9950X.
