AMD Ryzen Threadripper PRO 9985WX 64c/128t 3.2GHz-5.4GHz 350W (100-000000722)

Benchmark overview — AMD Ryzen Threadripper PRO 9985WX

The AMD Ryzen Threadripper PRO 9985WX is positioned as a high-end model within the Threadripper PRO 9000WX lineup,
just below the absolute flagship. It is designed for professional workloads that require very high sustained
multi-thread throughput, while maintaining strong single-thread responsiveness and full access to workstation-class
memory and I/O capabilities.

This benchmark section focuses on in-family comparison and cost-aware positioning, highlighting where the 9985WX
sits between upper mid-tier and top-tier PRO processors.

In-family performance comparison (Threadripper PRO 9000WX)

The figures below illustrate relative positioning inside the Threadripper PRO 9000WX lineup.
Multi-thread throughput is represented by an aggregate performance score, while single-thread ratings indicate
expected responsiveness in latency-sensitive workloads.

What this means in practice

The 9985WX delivers a substantial increase in sustained multi-thread performance compared to upper mid-tier models. This advantage becomes clearly visible in workloads that can keep a large number of cores active over long periods, such as large-scale rendering, scientific simulation, data analytics, and complex engineering pipelines.

Single-thread performance remains in the same responsiveness class as the rest of the PRO lineup. As a result, interactive tasks and mixed-use scenarios do not suffer despite the significantly higher core count.

Compared to the flagship model, the 9985WX provides most of the available parallel performance while avoiding the highest acquisition cost and the steepest drop in performance-per-euro.

Cinebench 2024 performance

These results confirm the CPU’s positioning as a high-throughput workstation processor. Single-core performance ensures strong responsiveness in latency-sensitive tasks, while the very high multi-core score reflects efficient scaling across a large number of cores under sustained load.

Cost-aware alternatives (indicative pricing)

The prices below are indicative examples and should be clarified in the product catalog or with a sales manager. They are used here solely to illustrate relative performance density.

From a price-to-performance perspective, the 9985WX marks the point where absolute throughput continues to rise, but performance per euro declines more sharply. This makes it most attractive for workloads that genuinely benefit from very high core counts.

Multiple lower-tier CPUs vs fewer high-end CPUs

In environments where workloads scale efficiently across multiple machines and licensing permits, deploying several mid-tier or upper mid-tier CPUs can sometimes deliver higher combined throughput than a single high-end processor.

• 2 × Threadripper PRO 9975WX → total throughput score: 212,928 (≈ €9,780)
• 1 × Threadripper PRO 9985WX → total throughput score: 154,304 (≈ €9,227)

This comparison represents a planning scenario rather than a guarantee. Real performance depends on software scaling behavior, memory and I/O requirements, infrastructure design, and licensing models.

How to read these numbers correctly

• Benchmarks indicate relative behavior under controlled conditions, not exact real-world performance.
• Single-thread metrics matter for responsiveness and lightly parallel workloads.
• Multi-thread metrics matter for rendering, simulation, and batch processing.
• Price-to-performance ratios are useful for planning, but system-level costs are equally important.
• Platform factors such as memory capacity, PCIe layout, cooling, and power delivery often have a greater impact than small score differences.

Practical takeaway

The Threadripper PRO 9985WX is a powerful near-flagship option for professional workstations. It is best suited for users with consistently heavy parallel workloads who need very high sustained throughput, but do not require the absolute maximum core count available in the lineup. For many professional environments, it represents a strong balance between extreme performance and overall cost efficiency.
