AMD Ryzen Threadripper PRO 9985WX 64-Core sTR5 Processor Box
The AMD Ryzen Threadripper PRO 9985WX is a 64-core enterprise workstation processor built for professionals running rendering, simulation, compilation and local AI workloads that demand massive parallel processing power. It combines the latest Zen 5 architecture with eight DDR5 memory channels, 128 PCIe 5.0 lanes, and overclocking support to eliminate bottlenecks in creative and computational work.
Why this product
64 cores, 128 threads, 256 MB L3 cache
Delivers full-spectrum compute power for rendering, physics simulation, AI model fine-tuning, and compilation tasks that benefit from extreme parallelism.
8 DDR5 memory channels, ECC enabled by default
Supports up to 6400 MT/s with error correction for data integrity in workloads where memory reliability is critical.
128 PCIe 5.0 lanes for expandability
Connects multiple high-bandwidth GPUs, NVMe drives, and accelerators without bottlenecking data transfer between components.
Unlocked for overclocking with Curve Optimizer
Per-core voltage tuning and Precision Boost Overdrive allow fine-tuning performance and power balance for specific workloads.
Zen 5 on 4nm process, 350 W TDP

- Boots and runs RAID configurations on NVMe drives via native PCIe, but motherboard and chipset must support this feature.
Best for
- Professional rendering farms and VFX studios processing cinematic workloads in parallel.
- Scientific computing, physics simulation, and computational analysis requiring high core counts.
- Local AI model fine-tuning and inference on billion-parameter models with data locality.
- Software compilation and build farms benefiting from extreme thread count and memory bandwidth.
- Enthusiasts and overclockers seeking maximum per-core frequency and power tuning flexibility.
Trade-offs
- General-purpose consumer computing; the workstation socket and chipset are enterprise-only.
- Systems requiring integrated graphics or onboard video output; this processor has none.
- Budget-conscious projects; the platform is enterprise-grade and significantly more expensive than mainstream consumer CPUs.
- Users seeking a complete boxed solution; cooler and thermal paste are not included.
- Low-power or fanless builds; the 350 W TDP and requirement for robust cooling eliminate passive or minimal-cooling designs.
