RYZEN THREADRIPPER PRO 9955WX

Power your professional workflow with the AMD Ryzen Threadripper PRO 9955WX, a high-performance 16-core, 32-thread desktop processor built on the latest Zen 5 architecture. With a blazing-fast 4.5GHz base clock and next-gen IPC improvements, this workstation-class CPU delivers exceptional speed and responsiveness for creative professionals, engineers, and developers handling intensive workloads like CAD, VFX, and simulation.

Designed for the sTR5 socket and rated at 350W TDP, the Threadripper PRO 9955WX supports cutting-edge technologies including DDR5 memory, PCIe Gen 5, and AMD PRO features for enterprise-grade security, manageability, and stability. Its 8-channel memory support and vast I/O capabilities make it ideal for complex, multi-threaded tasks requiring high bandwidth and reliability.

This model, part number 100-100000725WOF, is a boxed processor (WOF – without cooler), offering flexibility for custom workstation builds. Whether you're upgrading or building from scratch, the AMD Ryzen Threadripper PRO 9955WX delivers elite performance for professionals who demand speed, power, and precision.

Key Specifications:

  • Core / Thread Count: 16 cores and 32 threads
  • Base Clock: ~4.5 GHz (Boost up to 5.4 GHz)
  • L3 Cache: 64 MB
  • TDP: 350W
  • Architecture: Zen 5, 5nm process
  • Socket: sTR5
  • Memory Support: 8-channel DDR5 ECC Registered (RDIMM)
  • PCIe Lanes: 128 PCIe 5.0 lanes

Key Features:

  • Zen 5 Architecture (“Shimada Peak”)
    - Built on AMD’s latest Zen 5 microarchitecture for higher efficiency and better IPC (Instructions Per Clock).
  • High Clock Speeds
    ‑ Base clock of 4.5 GHz and boost clock up to 5.4 GHz for demanding single‑threaded or lightly threaded workloads.
  • Multithreading
    16 physical cores with Simultaneous Multithreading (SMT) gives 32 threads good for multitasking, parallel workloads, content creation, etc.
  • High Thermal Design Power (TDP)
    350 W TDP this is a power‑hungry CPU, requiring a robust cooling solution and good power delivery in the motherboard.
  • Platform Compatibility
    ‑ Socket: sTR5. Needs compatible motherboard (e.g. chipsets like WRX90, TRX50, Pro 695).

Best Suited For:

  • 3D Rendering, Animation, & VFX Workflows: With 16 cores / 32 threads, high clocks (4.5 GHz base, up to ~5.4 GHz boost)
  • CAD / Engineering / Simulation & CAE: Complex simulations (e.g. finite‑element analysis, computational fluid dynamics) often demand high throughput, many threads, large memory bandwidth, and ability to handle huge data sets.
  • Post‑Production / Video Editing & Encoding: For editing high‑resolution video (4K, 8K), color grading, effects, compositing, etc.
  • Software Development / Compilation / Build Servers: Building large codebases (especially with heavy templated C++ or lots of files), multiple projects or using virtual machines / containers benefit from many cores and fast I/O.
  • Virtualization, AI / Machine Learning Inferencing & Hybrid Workloads: If you want to run multiple virtual machines, GPU compute for AI inference, generative AI or ML pipelines locally, this CPU offers strong base: many threads, high memory bandwidth, large cache, PRO‑level enterprise security and platform support.

Why Choose the 9955WX?

If you want a workstation CPU that delivers top‑tier performance both in heavily multi‑threaded tasks and in high single‑thread speed work, thanks to its 16 cores/32 threads and base/boost clocks of 4.5‑5.4 GHz. It offers massive memory bandwidth with 8‑channel DDR5 support (including ECC), a large 64 MB L3 cache, 128 PCIe Gen5 lanes for GPUs and NVMe storage, plus enterprise‑grade features (AMD PRO, stability, overclocking) making it an excellent choice for creators, engineers, studios, and compute‑intensive workloads that demand both power and flexibility.

It brings server-grade performance into the desktop/workstation space with full platform reliability and features tailored for pros.
