AMD Ryzen Threadripper PRO 9975WX 32-Core 4.0GHz 350W Zen 5 CPU sTR5 – 100-100000723WOF

The World’s Fastest Workstation Processor

Designed to deliver and built for breakthroughs, the AMD Ryzen™ Threadripper™ PRO 9975WX stands as a monumental leap forward in professional computing. Serving as a flagship processor in the Ryzen Threadripper PRO 9000 WX-Series family, this desktop-class behemoth redefines what is possible for high-end workstations. Aimed directly at industry professionals, visual effects artists, architects, data scientists, and engineers, this processor is designed to eliminate computational bottlenecks entirely. Whether you are rendering complex 3D environments, compiling millions of lines of code, running massive data simulations, or multitasking across a half-dozen intensive professional applications simultaneously, the Threadripper PRO 9975WX provides the raw computational throughput necessary to accelerate your workflow and bring your most ambitious projects to life.

Groundbreaking Zen 5 Architecture

At the core of this processor’s staggering performance is the cutting-edge Zen 5 processor architecture, formerly known under the codename “Shimada Peak.” The chip is fabricated using TSMC’s highly advanced 4nm FinFET process for the CPU cores and a 6nm FinFET process for the internal I/O die, resulting in a highly optimized 5-die package design. The processor boasts an incredible 32 physical CPU cores and utilizes Simultaneous Multithreading (SMT) to provide a massive 64 threads of execution power. Running with a base clock speed of 4.0 GHz, the CPU can intelligently ramp up its performance using Precision Boost 2 technology, reaching a blistering maximum boost clock of up to 5.4 GHz during demanding single-threaded workloads.

To ensure these 32 cores are constantly fed with data, AMD has equipped the 9975WX with a colossal cache hierarchy. The processor features 2560 KB of ultra-fast L1 cache, 32 MB of dedicated L2 cache, and a massive 128 MB of shared L3 cache. This huge pool of memory sitting right next to the processing cores drastically reduces latency and ensures that your most frequently accessed data is available instantaneously. Operating with a default Thermal Design Power (TDP) of 350W, the processor is unlocked for custom overclocking, featuring Precision Boost Overdrive and Curve Optimizer Voltage Offsets for enthusiasts and system integrators looking to extract every ounce of performance.

Unrivaled Memory Bandwidth and Capacity

Professional workloads demand not just processing power, but immense memory capacity and bandwidth. The Threadripper PRO 9975WX completely modernizes workstation memory standards by fully supporting next-generation DDR5 system memory operating at speeds up to 6400 MT/s. Taking full advantage of an 8-channel memory architecture, this CPU delivers memory bandwidth that completely dwarfs standard desktop processors.

Because data integrity is paramount in professional and enterprise environments, the processor utilizes RDIMM (Registered DIMM) memory subtypes with Error-Correcting Code (ECC) support enabled by default. This ensures that single-bit memory errors are caught and corrected on the fly, preventing catastrophic system crashes and data corruption during multi-day rendering or simulation tasks. Furthermore, the processor integrates AMD EXPO™ Memory Overclocking Technology, which allows users to apply highly optimized, user-friendly overclocking profiles to achieve accelerated memory speeds without complex manual tuning.

Massive Expansion with PCIe 5.0

A high-end workstation relies heavily on its ability to interface with multiple graphics cards, vast storage arrays, and high-speed networking adapters. The Threadripper PRO 9975WX accommodates this with native support for the PCIe® 5.0 standard. The processor offers a staggering 148 total native PCIe lanes, with 144 usable lanes and 128 lanes fully dedicated to the ultra-fast PCIe 5.0 specification. This provides the bandwidth necessary to run multiple flagship GPUs at full speed simultaneously without any bottlenecks, which is critical for AI training, deep learning, and advanced GPU rendering.

On the storage front, this massive PCIe layout enables unparalleled NVMe configurations. The processor supports advanced boot configurations and hardware-level NVMe RAID setups, including RAID 0, 1, 5, and 10. Whether you need massive redundant storage or a striped array for blistering read/write speeds when scrubbing uncompressed 8K video, the 9975WX handles it effortlessly. Additionally, the processor natively supplies 4 SATA ports and 4 ultra-fast USB 3.2 Gen 2 (10Gbps) ports directly from the CPU, ensuring that your peripherals and legacy storage devices connect with zero latency.

Enterprise-Grade Security and AMD PRO Manageability

When managing proprietary corporate data and valuable intellectual property, security cannot be an afterthought. The Threadripper PRO 9975WX is fortified with a comprehensive suite of AMD PRO technologies. Central to this is AMD Memory Guard, a technology that provides full, real-time system memory encryption. Should your physical workstation be compromised or stolen, Memory Guard ensures your data remains completely unreadable. This is reinforced by the AMD Secure Processor, a dedicated on-chip security system that validates code prior to execution, preventing unauthorized software and firmware-level attacks.

The processor’s deep integration with modern operating systems ensures compliance with the highest enterprise security standards. It fully supports Windows Secured-Core PC requirements, Virtualization-Based Security (VBS), Windows Device Guard, and Firmware TPM. Protection against control-flow and memory-based attacks is bolstered by features like Guest Mode Execution (GMET) Trap, AMD Enhanced Virus Protection (NX bit), and Second Level Address Translation (SLAT). For IT departments, the inclusion of DASH support and robust AMD PRO Manageability features simplifies the deployment, imaging, and remote management of workstation fleets across large corporate networks.

Ecosystem Requirements and Platform Compatibility

The AMD Ryzen Threadripper PRO 9975WX is designed for the sTR5 CPU socket and is fully compatible with high-end workstation motherboards utilizing the WRX90, TRX50, and Pro 695 supporting chipsets. Operating such a powerful piece of hardware requires robust cooling; note that a thermal solution (PIB) is not included in the box, requiring system builders to select a specialized, high-performance liquid or air cooler capable of taming its 350W TDP and maintaining temperatures below its 95°C maximum operating threshold. Furthermore, the processor is strictly dedicated to compute performance and does not feature integrated graphics, meaning a discrete graphics card is strictly required for display output. The platform natively supports modern 64-bit operating systems including Windows 11, Windows 10, Ubuntu x86, and RHEL x86, ensuring flawless integration into both standard and specialized production pipelines.
