Description

Introducing the AMD Ryzen Threadripper Pro 9955WX 16-Core 4.5GHz CPU. A high-end workstation processor designed to deliver extreme performance for professional creators, engineers, and developers who need consistent, scalable compute power. Built on AMDs advanced Zen 5 architecture and manufactured using a 4nm FinFET process, this 16-core, 32-thread CPU represents a modern balance between raw multi-threaded throughput and strong single-core responsiveness. With a base clock of 4.5GHz and boost frequencies reaching up to 5.4GHz, it is engineered to handle demanding workloads such as 3D rendering, simulation, video production, and AI development without bottlenecks.

At its core, this processor is built for sustained heavy workloads. The combination of 16 cores and 32 threads allows it to efficiently distribute complex tasks across multiple execution paths, significantly improving productivity in parallelized applications. Its large cache hierarchy-including 1280KB of L1 cache, 16MB of L2 cache, and a substantial 64MB of L3 cache-helps reduce memory latency and improves data access speeds during intensive computation. This makes it especially effective in environments where large datasets or real-time processing are common. The platform capabilities of the Ryzen Threadripper PRO 9955WX are equally impressive. Supporting the sTR5 socket and compatible with WRX90, TRX50, and PRO 695 chipsets, it offers a scalable foundation for high-end workstation builds. PCIe 5.0 support enables next-generation bandwidth for GPUs, NVMe storage, and accelerator cards, making it well-suited for GPU-accelerated workflows and data-heavy pipelines. Combined with AMD EXPO memory tuning technology, users can achieve optimized performance from high-speed DDR memory configurations with improved stability and efficiency.

On the enterprise and professional side, the processor integrates AMD PRO Technologies, delivering enhanced security features, manageability tools, and long-term platform stability. With planned software stability and extended availability support, it is designed for professional environments where consistency and reliability are critical. It also supports major operating systems including Windows 11, Windows 10, Ubuntu, and RHEL, allowing flexibility across creative studios, engineering firms, and enterprise deployments. Despite its advanced capabilities, the Ryzen Threadripper PRO 9955WX does not include a thermal solution, giving system builders the freedom to choose a cooling system tailored to their performance and acoustic requirements. With a default TDP of 350W, it demands a robust cooling setup to sustain peak performance under load.
