AMD Ryzen Threadripper PRO 9995WX

The AMD Ryzen Threadripper PRO 9995WX is a 96-core, 192-thread workstation processor built on the Zen 5 architecture (codename Shimada Peak) and manufactured on TSMC’s 4 nm process. It sits at the very top of the desktop-workstation hierarchy, achieving a perfect 100th percentile ranking among all CPUs in the benchmark database. Its average benchmark score of 406,395 places it in a class shared only with the most extreme server processors, and the data shows it is neither the fastest nor the slowest in its immediate peer group—but its specific balance of single-thread speed and massive parallel throughput makes it a distinct choice for professionals who need both.

How It Compares

Against the AMD EPYC 9655P, the Threadripper PRO 9995WX holds a 2.5% advantage in average benchmark score. That margin is narrow, but it is consistent across the data, meaning the 9995WX edges out this single-socket EPYC in aggregate performance. The EPYC 9655P, however, is designed for dense server deployments, so the Threadripper’s lead here is notable for workstation buyers who expect top-tier compute without sacrificing platform flexibility.

The AMD EPYC 9745 is the only rival in this group that beats the 9995WX, with the Threadripper trailing by 4.6%. That deficit is small enough to be workload-dependent, but the EPYC 9745’s higher average score suggests it has an edge in certain multi-threaded server tasks. For a workstation part, the 9995WX still delivers nearly all of the EPYC 9745’s performance while offering a different platform feature set.

Compared to the AMD EPYC 9655, the Threadripper PRO 9995WX leads by 8.8%. This is a more comfortable margin, and it highlights the 9995WX’s strength as a high-frequency, high-core-count part relative to a similar EPYC sibling. The 8.8% gap is meaningful for rendering or simulation workloads where every percentage point of throughput translates directly to reduced wall-clock time.

The largest lead in the rival set is against the AMD EPYC 9754, where the 9995WX is 11.5% faster on average. The EPYC 9754 is a high-core-density server chip, yet the Threadripper’s combination of Zen 5 efficiency and higher clock potential gives it a decisive aggregate advantage. This positions the 9995WX as a superior choice for users who need server-level core counts but with workstation-oriented responsiveness.

Who Should Consider It

Professionals running multi-threaded content creation workloads—such as 3D rendering, video encoding, or complex simulations—will find the 9995WX’s 96 cores and 192 threads directly beneficial. The Cinebench R23 multi-core score of 148,601 and PassMark multi-thread score of 174,825 indicate that tasks which scale across many threads will complete substantially faster than on any mainstream desktop processor, and the 11.5% lead over the EPYC 9754 confirms it outpaces even some server parts in aggregate throughput.

For single-thread-bound applications, such as legacy software, scripting, or certain CAD tools that rely on one core, the 9995WX still performs exceptionally well. Its Cinebench R23 single-core score of 20,979 and PassMark single-thread score of 4,565 are near the top for any CPU, meaning interactive responsiveness and lightly threaded tasks will not feel sluggish despite the processor’s massive core count. This makes it a viable option for engineers who alternate between heavy simulation and everyday desktop use.

Data-heavy workloads like compression, encryption, and scientific computing are also a strong fit. The PassMark data compression score of 3,627,619 and data encryption score of 215,680 are extremely high, indicating that the processor excels at both memory-bandwidth-intensive and cryptography-heavy tasks. The eight-channel DDR5 memory support with 409.6 GB/s bandwidth further reinforces this, making the 9995WX ideal for large in-memory datasets or database workloads.

Office and general productivity users, however, will be over-served by this processor. The sheer core count and 350 W TDP are unnecessary for typical spreadsheet, email, or web-browsing tasks, and the data shows that a mid-range workstation CPU would deliver similar single-thread performance at a fraction of the complexity. The 9995WX is best reserved for professionals who can consistently utilize more than half of its 192 threads.

Benchmark Performance

The Cinebench R23 multi-core score of 148,601 is the headline figure, and it sits 8.8% above the EPYC 9655 and 11.5% above the EPYC 9754, while being 2.5% ahead of the EPYC 9655P and 4.6% behind the EPYC 9745. This pattern holds across Cinebench R20, where the 9995WX scores 62,412 multi-core, and Cinebench R15, where it scores 14,978 multi-core. The consistency of these deltas suggests that the 9995WX’s performance advantage is not a single-benchmark artifact but a genuine characteristic of its architecture.

Single-core performance is equally strong, with Cinebench R23 single-core at 20,979 and Cinebench R20 single-core at 8,811. These scores are close to what high-end desktop CPUs achieve, but the 9995WX maintains this level while also offering 96 cores—a combination that few rivals can match. The PassMark single-thread score of 4,565 reinforces this, showing that the processor does not compromise on per-core speed to achieve its parallel throughput.

In specialized PassMark tests, the 9995WX shows particular strengths. Floating-point math scores 707,600, integer math scores 1,220,090, and random string sorting scores 426,857—all indicative of excellent general-purpose arithmetic and data manipulation capabilities. The extended instructions score of 247,436 and find prime numbers score of 1,573 further demonstrate its prowess in SIMD-heavy and algorithmic workloads. Physics simulation, as measured by PassMark, scores 20,011, which is robust for workstation-class computation.

The average benchmark score of 406,395, when compared to the nearest rivals’ scores, places the 9995WX in a tight competitive band. The data shows it is 2.5% faster than the EPYC 9655P, 8.8% faster than the EPYC 9655, and 11.5% faster than the EPYC 9754, but 4.6% slower than the EPYC 9745. These margins are small in absolute terms, but they matter for users who run long-duration jobs where a 5% difference can translate to hours of saved time.

Platform and Compatibility

The 9995WX uses AMD Socket sTR5, which is specific to the Threadripper PRO line and requires a compatible workstation motherboard. This socket supports the processor’s 128 PCIe Gen 5 lanes (CPU only), providing extensive connectivity for multiple GPUs, NVMe storage, and high-speed networking cards. The platform is designed for serious expansion, with enough lanes to run several accelerators simultaneously without bottlenecking.

Memory support is eight-channel DDR5, which doubles the bandwidth of typical quad-channel desktop platforms. With a maximum memory bandwidth of 409.6 GB/s, the 9995WX can feed its 96 cores efficiently, particularly in memory-intensive workloads like large-scale simulations or in-memory databases. ECC memory is supported, which is a critical feature for professionals who need error correction during long compute runs.

The processor is unlocked, allowing overclocking if the motherboard and cooling permit it, though the 350 W TDP means that headroom is limited without robust thermal solutions. The production status is active, and the release date is July 22, 2025. The launch MSRP is $11700, and the part number is 100-000001361.

Upgrade path within the sTR5 platform is determined by AMD’s roadmap, but the 9995WX represents the top of the current Zen 5 Threadripper generation, so users are unlikely to need an upgrade for several years. The platform’s PCIe Gen 5 support ensures compatibility with future peripherals, and the DDR5 memory standard is current, so there is no immediate need for a platform refresh.

Single-Thread vs Multi-Thread Behavior

The 9995WX delivers a rare combination: exceptional multi-thread performance without sacrificing single-thread speed. Its Cinebench R23 single-core score of 20,979 is only slightly lower than what dedicated high-frequency desktop CPUs achieve, yet it simultaneously produces a multi-core score of 148,601. This balance means that workloads which interleave heavily threaded tasks with interactive, single-threaded operations—such as a designer rendering a scene while adjusting UI elements—will not experience the sluggishness common on many high-core-count server parts.

In contrast, rival server processors like the EPYC 9754, which the 9995WX beats by 11.5% on average, often prioritize raw core count over per-core clock speed. The Threadripper’s 5.40 GHz boost clock, versus its 2.50 GHz base clock, indicates significant frequency headroom that benefits single-threaded bursts. The PassMark single-thread score of 4,565 confirms this, making the 9995WX suitable for older applications that are not well-parallelized.

For workloads that are purely multi-threaded, the 9995WX’s 96 cores scale effectively, as shown by its PassMark multi-thread score of 174,825 and data compression score of 3,627,619. The eight-channel memory bus ensures that all cores have adequate data throughput, preventing memory bottlenecks that can cap performance on lower-bandwidth platforms. The data indicates that the processor’s multi-thread performance is not just a sum of many weak cores, but a coherent high-bandwidth design.

The practical implication is that users can run a mix of heavy batch jobs and interactive work without compromise. While the EPYC 9745 may edge out the 9995WX by 4.6% in aggregate benchmarks, that rival likely does not offer the same single-thread responsiveness, making the Threadripper a better fit for workstation environments where both aspects matter.

Power and Thermals

The 9995WX has a 350 W TDP, which places it in the high-power workstation class. This TDP requires a substantial cooling solution—typically a large tower air cooler with multiple heat pipes or a high-end liquid cooler—to maintain boost clocks under sustained load. The data does not specify thermal dissipation figures, but the 350 W TDP implies that the processor generates significant heat, especially when all 96 cores are active.

Given the 350 W TDP, the platform’s power delivery system must be robust, and users should expect higher electricity consumption compared to mainstream desktop processors. The 4 nm process node from TSMC helps mitigate some efficiency losses, but the sheer core count means that power draw is inherently high. The processor’s base clock of 2.50 GHz is relatively low, which suggests that idle or light-load power consumption may be manageable, but full-load scenarios will push the cooling system.

The unlocked multiplier allows for overclocking, but doing so will increase both power draw and heat output beyond the 350 W TDP. Benchmark results show that the processor already performs at a high level, so overclocking is likely unnecessary for most users and could require custom water cooling to avoid thermal throttling. The platform’s 128 PCIe Gen 5 lanes and eight-channel memory also add to system-level power requirements, so a high-wattage power supply is advisable.

In terms of cooling tier, the 350 W TDP places the 9995WX above typical desktop processors but below some extreme server parts. A capable air cooler may suffice for stock operation, but for sustained all-core workloads, a high-quality liquid cooler is recommended to keep temperatures within safe limits and maintain consistent boost clocks. The data shows no thermal throttling figures, but the TDP class alone indicates that thermal management is a critical consideration for any build using this processor.
