AMD Ryzen Threadripper PRO 9955WX
AMD Ryzen Threadripper PRO 9955WX Specifications and Performance Analysis
The AMD Ryzen Threadripper PRO 9955WX is based on the Shimada Peak architecture and is manufactured using the 4 nm process at the TSMC foundry. It is compatible with the sTR5 socket used by WRX90, TRX50, Pro 695 chipsets and supports PCIe Gen 5, 128 Lanes (CPU only), as well as DDR5 ECC Reg memory with speeds of up to 6400 MT/s across Eight-channel memory. This processor features 16 cores operating at a base clock of 4.50 GHz and a boost clock of up to 5.40 GHz, for a total of 32 threads. It is equipped with 64 kB of L1 cache, 1024 kB of L2 cache, and 64 MB of L3 cache.
This CPU belongs to the AMD Ryzen™ Threadripper™ PRO 7000 / 9000 series and is designed for high-end professional workstations. It supports DDR5 registered ECC (RDIMM) memory exclusively, ensuring maximum reliability, stability, and scalability for mission-critical workloads. The platform provides eight memory channels, delivering extremely high memory bandwidth of 409.6 GB/s required for large datasets and memory-intensive applications. It also offers extensive PCIe 5.0 connectivity, enabling multiple next-generation GPUs, high-speed NVMe storage devices, and professional accelerator cards. With a thermal design power (TDP) of 350 W, this processor is optimized for sustained all-core workloads such as 3D rendering, engineering simulations, scientific computing, virtualization, and AI workloads. While gaming is not the primary focus of this platform, performance remains strong in GPU-bound scenarios.This CPU does not include integrated graphics. A discrete graphics card is required for display output.
Application Performance
AMD Ryzen Threadripper PRO 9955WX is a high-end CPU, achieving a relative application performance score of 106.43% of the best possible desktop CPU performance. This CPU is highly suitable for demanding professional applications such as 3D rendering, video editing, and other heavy workloads that require strong multi-core performance and high sustained throughput.
The application performance-per-price ratio of AMD Ryzen Threadripper PRO 9955WX is 20.6%, indicating lower value in this category. However, since this is a high-performance CPU, it remains a suitable option for users who prioritize performance and are less concerned about budget constraints.
Gaming Performance
AMD Ryzen Threadripper PRO 9955WX is a mid-range gaming CPU, achieving a relative gaming performance score at 1080p resolution of 78.26% compared to the best possible desktop CPU gaming performance. This CPU provides solid mid-level gaming, performance and is best paired with corresponding mid-range graphics cards. Note that CPU-related performance limitations decrease as GPU performance lowers—particularly at higher resolutions—since the GPU becomes the bottleneck.
The gaming performance-per-price score of 10.0%, this CPU does not offer strong value in this category. As this CPU does not deliver top-tier gaming performance and also has a low gaming performance-to-price ratio, it represents poor value. More competitive options are available at a similar price point.
