The AMD Ryzen Threadripper PRO 9985WX is a professional-grade workstation powerhouse built on the "Shimada Peak" architecture. Released in July 2025, it serves as a high-frequency, high-core-count middle ground in the Zen 5 lineup, offering 64 cores and 128 threads for users who require massive parallel processing without the extreme cost of the 96-core flagship.
Utilizing a 4nm manufacturing process, the 9985WX delivers a substantial generational uplift. While it maintains the 64-core count of the previous 7985WX, the move to Zen 5 provides a roughly 13%–17% increase in single-threaded tasks and over 15% better multi-threaded performance.
Clock Speeds: A base clock of 3.2 GHz and a maximum boost of 5.4 GHz.
Cache: A massive 256MB of L3 cache ensures the processor can handle massive datasets with minimal latency.
The 9985WX is designed for the sTR5 socket and specifically optimized for WRX90 motherboards. This platform unlocks enterprise-level features essential for mission-critical reliability:
8-Channel DDR5: Supports up to 2TB of ECC RDIMM at 6400 MT/s, providing nearly 400 GB/s of memory bandwidth.
PCIe 5.0 Connectivity: Features 128 usable PCIe 5.0 lanes, allowing for complex multi-GPU arrays and high-speed storage without bottlenecks.
AMD PRO Security: Includes a dedicated security processor and features like Memory Guard for real-time memory encryption.
