About AMD Ryzen Threadripper PRO 9945WX

The AMD Ryzen Threadripper PRO 9945WX is the entry-point workstation powerhouse of the Zen 5 "Shimada Peak" family. Released in July 2025, this 12-core, 24-thread processor is built for enterprise environments that require the expansive I/O and memory bandwidth of the Threadripper PRO platform without the cost of the ultra-high core count models.

Despite having fewer cores than its 96-core siblings, the 9945WX benefits from the massive IPC (Instructions Per Clock) jump provided by the 4nm Zen 5 architecture. It is optimized for tasks that rely on high frequency and low latency rather than pure parallelization, such as CAD design, complex engineering software, and high-frequency trading.

Clock Speeds: It features a high 4.7 GHz base clock and a maximum boost of 5.4 GHz, ensuring snappy performance in single-threaded applications.

Efficient Cache: It packs 64MB of L3 cache, which, combined with the Zen 5 architecture, significantly reduces data bottlenecks for memory-sensitive professional workflows.

The "PRO" designation signifies that this chip is designed for the WRX90 platform and the sTR5 socket. This provides a massive step up in system-level expandability compared to the standard TRX50 HEDT platform:

8-Channel DDR5: Supports up to 2TB of RDIMM memory at 6400 MT/s, providing the bandwidth necessary for massive data sets and local AI model fine-tuning.

PCIe 5.0 Connectivity: Offers 128 usable PCIe 5.0 lanes, allowing for a vast array of high-speed GPUs, networking cards, and NVMe storage without performance throttling.

AMD PRO Technologies: Includes a suite of enterprise features like AMD Memory Guard, manageable DASH support, and a dedicated security processor for mission-critical data protection.
