AMD Ryzen Threadripper PRO 9985WX - 3 Variant Attributes - Processor

AMD Ryzen Threadripper PRO 9985WX arrives as a flagship workstation processor in the AMD Ryzen™ Threadripper™ PRO 9000 WX-Series, designed for extreme multi‑threaded workloads and professional content creation.

The AMD Ryzen Threadripper PRO 9985WX is built on a 64‑core, 128‑thread architecture that delivers exceptional parallel processing power. With a base frequency of 3.2 GHz and a boost frequency up to 5.4 GHz, this processor balances high single‑thread responsiveness with massive multi‑core throughput.

On the memory side, the 9985WX supports DDR5‑SDRAM across octa‑channel memory lanes, ensuring huge memory bandwidth for large data sets and complex simulations. The processor includes 256 MB of L3 cache to reduce latency and accelerate data access for demanding applications.

Connectivity and expansion are industry-leading thanks to up to 148 PCI Express lanes with PCIe 5.0 support, enabling multi‑GPU setups, high‑speed NVMe storage arrays, and extensive I/O for professional workstations. The CPU uses the Socket sTR5 and is supplied in a boxed package; note that a cooler is not included.

Thermal and power characteristics reflect its workstation class: a Thermal Design Power (TDP) of 350 W and a minimum operating temperature rating of 95 °C mean robust cooling and power delivery are essential. The 9985WX is a 64‑bit processor and does not include integrated graphics, making it ideal for systems with discrete GPUs tailored to the task.

Typical use cases include 3D rendering farms, large‑scale engineering simulations, video post‑production workflows, scientific computing, and software compilation servers that benefit from extreme core counts and memory bandwidth. Businesses and professionals will find the 9985WX suited to environments that demand uncompromising computational performance.

Key selling points:

• 64 cores / 128 threads for massive parallel processing
• Up to 5.4 GHz boost frequency for strong single‑thread performance
• Octa‑channel DDR5 support and 256 MB L3 cache for high memory throughput
• 148 PCIe 5.0 lanes for extensive expansion and I/O
• 350 W TDP — designed for fully‑equipped workstation builds

When planning a build with the AMD Ryzen Threadripper PRO 9985WX, prioritize a powerful cooling solution, a compatible sTR5 motherboard with robust VRMs, and enterprise‑grade power delivery to fully exploit the processor’s capabilities.
