The AMD Ryzen Threadripper PRO 9985WX is a Zen 5 (Shimada Peak) professional workstation processor with 64 cores and 128 threads, a 3.2 GHz base clock that boosts to 5.4 GHz, a massive 256 MB of L3 cache and full 8-channel DDR5-6400 ECC memory support — built for the most demanding professional rendering, simulation and AI workstations. Supplied boxed without a cooler (part number 100-100000722WOF, EAN 0730143317481). Typically in stock with fast delivery across Cyprus.
Compatibility — read before you buy
This is a professional workstation processor for the AMD Socket sTR5 (WRX90 chipset) PRO platform — it requires a WRX90 motherboard and is not compatible with consumer AM4/AM5 or the non-PRO TRX50 boards. It supports 8-channel registered ECC DDR5-6400 up to 2 TB and provides 128 PCIe 5.0 lanes. With a 350W TDP it ships without a cooler and requires a high-performance sTR5 liquid or air cooler.

Key Features
64 Cores, 128 Threads
Sixty-four Zen 5 cores with SMT deliver extreme workstation multi-threaded performance for rendering, simulation and AI development.
8-Channel DDR5-6400 ECC
Full 8-channel registered ECC DDR5-6400 support (up to 2 TB) provides enormous memory bandwidth and capacity with error correction for data-integrity-critical work.
128 PCIe 5.0 Lanes
A massive 128 PCIe 5.0 lanes allow multiple GPUs, NVMe arrays and high-speed cards simultaneously — ideal for multi-accelerator professional rigs.
PRO Manageability & Security
Threadripper PRO adds AMD PRO management, security and memory-guard features for enterprise workstation deployments.
Technical Specifications
Frequently Asked Questions
Singular Expert Insight
The Threadripper PRO 9985WX pairs 64 Zen 5 cores with the full 8-channel DDR5-6400 and 128 PCIe 5.0 lanes of the WRX90 PRO platform — extreme professional throughput for rendering, simulation and AI just below the flagship 9995WX. For fewer cores the 9975WX (32-core) and 9965WX (24-core) cost less. Pair it with registered ECC DDR5 memory across all eight channels for maximum bandwidth.
Buyer's Guide
Buy it if
You build the most demanding professional workstations and want 64 Zen 5 cores with 8-channel ECC DDR5-6400 and 128 PCIe 5.0 lanes on WRX90.
Skip it if
You want a gaming or mainstream desktop CPU (a Ryzen 9 is far cheaper), or your workloads do not scale to 64 cores.
Also consider
The Threadripper PRO 9975WX (32 cores) or 9965WX (24 cores) for less, or the flagship 9995WX (96 cores) for maximum compute.
