High-End Workstation
The AMD Ryzen Threadripper PRO 9995WX is a 96-core, 192-thread Zen 5 workstation processor built on TSMC 4nm, offering 8-channel DDR5-6400, up to 2 TB of ECC memory, and 128 PCIe 5.0 lanes for extreme rendering, simulation, and AI workloads.
The Ryzen Threadripper PRO 9995WX combines 96 Zen 5 cores, 192 threads, 8-channel DDR5-6400 ECC memory, and 128 PCIe 5.0 lanes in a single sTR5 socket. It targets extreme workloads like VFX rendering, FEA/CFD simulation, and large-scale AI, where its core density and bandwidth are more important than cost or power efficiency.
For anything less than heavily parallel professional tasks, lower-core Threadripper or Ryzen 9 parts offer better value.
Specifications
Performance
Class-leading multi-threaded performance for rendering, compilation, and batch processing, scaling well with core-heavy workloads.
Excellent for consolidating many VMs or containers with ample memory and PCIe connectivity for virtual GPUs.
More than capable for high-refresh-rate gaming, but most gaming workloads cannot utilize 96 cores, so you pay for cores you rarely use.
At 350 W TDP and often higher under load, efficiency is lower than mainstream parts, requiring robust cooling and power supply.
- •Strong single-threaded performance thanks to Zen 5 and high boost clocks.
- •Most games cannot use more than a fraction of the 96 cores.
- •Platform cost and power are hard to justify for gaming alone.
- •Strong CPU-based inference and fine-tuning for models that fit in system memory.
- •No dedicated NPU; AI acceleration is via AVX-512 and vector units.
- •Best suited as a CPU companion to discrete GPUs for larger models.

History
AMD introduced the Ryzen Threadripper PRO family in 2020 to address professional workstation users who needed more cores and memory bandwidth than mainstream Ryzen could offer, along with enterprise-grade reliability. Over successive generations, Threadripper PRO pushed core counts from 64 to 96 and memory support from DDR4 to DDR5, consistently targeting the high end of the workstation market. In 2025, AMD launched the Zen 5-based Ryzen Threadripper PRO 9000 WX-Series, codenamed Shimada Peak, alongside the 5-year anniversary of Threadripper PRO.
The flagship 9995WX took the existing 96-core formula but replaced the Zen 4 cores with Zen 5, increased boost clocks, and moved to faster DDR5-6400 memory. This generation cemented AMD’s leadership in single-socket workstation performance, with reviews showing clear advantages over Intel’s Xeon W-3400/3500 series in many rendering and simulation workloads, though at substantially higher cost and power.
Improvements over Previous Generation
- Zen 5 architecture with ~16% IPC uplift over Zen 4
- Higher boost ceiling (5.4 GHz vs 5.1 GHz)
- Faster DDR5-6400 memory support (vs DDR5-5200 on 7000-series)
- Higher single-threaded and multi-threaded performance at similar TDP

A single 9995WX has fewer cores than dual EPYC but lower latency and simpler workstation qualification; dual EPYC wins on raw core count and memory capacity for highly parallel workloads.
Is the 9995WX suitable for virtualization?
Yes, with 96 cores, 192 threads, 8-channel memory, and extensive virtualization features (AMD-V, AMD-Vi, AVIC, VBS), it is excellent for consolidation of many VMs or VDI workloads.
Does the 9995WX include a cooler?
No, AMD specifies that a thermal solution is not included in the box; you must provide a compatible sTR5 cooler.
What is the maximum turbo power of the 9995WX?
AMD does not publish a separate max turbo power; under heavy all-core loads, power draw can significantly exceed the 350 W TDP, especially with PBO enabled.
Can I use the 9995WX for AI workloads?
Yes, it is strong for CPU-based inference and fine-tuning, especially with AVX-512, but for large models you will still want discrete GPUs for acceleration.
How does the 9995WX compare to the 9980X HEDT part?
The 9995WX has more cores and 8-channel memory with PRO features, while the 9980X is a 64-core HEDT part with quad-channel memory and no PRO manageability, at a lower price.
Is the 9995WX future-proof?
As a top-bin workstation CPU, it should remain capable for several years in highly parallel workloads, but its platform is expensive and specialized; future-proofing depends more on your workload growth than the CPU alone.
