AMD Ryzen Threadripper 9980X vs AMD Ryzen Threadripper PRO 9995WX Comparison

The AMD Ryzen Threadripper PRO 9995WX and the AMD Ryzen Threadripper 9980X are both Zen 5 parts on the same sTR5 socket, but they are not aimed at the same buyer. The data is unambiguous: the PRO 9995WX wins every single head-to-head benchmark listed, 17 wins to zero. The PRO chip is the top-tier workstation part, sitting at the 100th percentile of all CPUs with an average benchmark score of 412,068, while the 9980X is a very fast desktop part at the 99th percentile with an average score of 321,753. You should pick the PRO 9995WX if your workload scales with core count and memory bandwidth, and you need the absolute maximum throughput. The 9980X is the better pick for a high-end desktop system where you want most of the multi-core muscle and a much lower launch MSRP, but you are willing to sacrifice the PRO's extra cores, cache, and memory channels. The 9980X is also a sensible choice if you are building a system that does not need eight-channel memory or 128 PCIe lanes.

The Verdict

The verdict here is about matching silicon to the job, not about quality—both are exceptional. The Ryzen Threadripper PRO 9995WX is the clear choice for a dedicated workstation or server node where multi-threaded rendering, simulation, and data processing are the primary tasks. Its 96 cores and 192 threads, combined with 384 MB of L3 cache and eight-channel DDR5 memory, put it in a different performance class. The benchmarks show it is 13.8% ahead of the 9980X in every Cinebench multi-core test, and its advantage grows to 25.2% in data compression and 31.5% in data encryption. The PRO part also boasts 128 PCIe Gen 5 lanes, which is critical for systems with multiple high-end GPUs or NVMe storage arrays.

The Ryzen Threadripper 9980X is the better option for a high-end desktop that still needs massive compute power but does not require the PRO's enterprise features. With 64 cores and 128 threads, it is still a monster, and its 256 MB of L3 cache is substantial. It has a base clock of 3.20 GHz compared to the PRO's 2.50 GHz, which helps it keep pace in single-threaded tasks. The data shows the 9980X is only 0.1% behind the PRO in the Passmark single-thread test, making them effectively identical in lightly-threaded work. Its quad-channel memory and 80 PCIe lanes are plenty for most desktop builds. The launch MSRP difference is significant: the PRO 9995WX is $11700, while the 9980X is $4999. If your budget is a consideration and you do not need the PRO's extra cores and bandwidth, the 9980X is the practical choice.

Architecture Differences

Both CPUs are built on the Zen 5 architecture with the codename Shimada Peak, manufactured by TSMC on a 4 nm process node. The core design is the same, with each core featuring 64 KB of L1 cache and 1 MB of L2 cache. The fundamental difference lies in the silicon configuration. The PRO 9995WX is a massive chip with 99,780 million transistors spread across 12 chiplets, each with a die size of 70.6 mm². The 9980X uses a smaller configuration with 66,520 million transistors across 8 chiplets of the same 70.6 mm² size. This is why the PRO part has 96 cores and the 9980X has 64 cores.

The cache hierarchy is also a major architectural split. The PRO 9995WX has a total of 384 MB of L3 cache, while the 9980X has 256 MB. This extra cache is a direct result of the additional chiplets. The memory controllers are configured differently as well: the PRO 9995WX supports eight-channel DDR5 memory, while the 9980X supports quad-channel DDR5. This doubles the theoretical memory bandwidth from 204.8 GB/s on the 9980X to 409.6 GB/s on the PRO 9995WX. Both support ECC memory, which is crucial for error-sensitive workstation workloads. The PCIe lane allocation is another key differentiator, with the PRO offering 128 Gen 5 lanes (CPU only) compared to 80 lanes on the 9980X.

Specification Differences

The specification sheet shows a clear performance hierarchy. The PRO 9995WX has 96 cores and 192 threads, while the 9980X has 64 cores and 128 threads. The base clock differs, with the 9980X running at 3.20 GHz and the PRO at 2.50 GHz, though both boost to 5.40 GHz. The PRO has a larger L3 cache at 384 MB versus 256 MB. The memory bus is a major difference: the PRO uses eight-channel DDR5 with 409.6 GB/s bandwidth, while the 9980X uses quad-channel DDR5 with 204.8 GB/s. The PCIe configuration also differs, with the PRO having 128 Gen 5 lanes and the 9980X having 80. Both are unlocked for overclocking, share the same 350 W TDP, and use the same sTR5 socket. The PRO is classified for the Server/Workstation segment, while the 9980X is for Desktop. The PRO was released on 2025-07-22, and the 9980X was released a week later on 2025-07-29.

Head-to-Head Benchmarks

The benchmark results are a clean sweep for the PRO 9995WX. In the Cinebench suite, the PRO is consistently 13.8% ahead in the R15, R20, and R23 multi-core tests. For example, in Cinebench R23 multi-core, the PRO scores 148,601 versus 130,529 for the 9980X. The single-core Cinebench results show a similar 13.8% to 13.9% advantage for the PRO, with scores like 20,979 versus 18,427 in R23 single-core. This is notable because the 9980X has a higher base clock, but the PRO's architecture still edges it out.

The Passmark suite reveals where the PRO's extra cores create massive gaps. The largest win for the PRO is in the Passmark physics test, where it scores 16,860 against 8,001 for the 9980X, a delta of 110.7%. The find prime numbers test also shows a huge 91.9% advantage for the PRO (1,476 vs 769). In integer math, the PRO is 38% ahead (1,203,634 vs 872,071), and in floating-point math, it is 29.7% ahead (725,066 vs 559,003). Data encryption shows a 31.5% lead for the PRO (206,662 vs 157,137), and data compression shows a 25.2% lead (3,723,652 vs 2,974,534). The random string sorting test has a 43.4% delta in favor of the PRO. The only test where the two are nearly identical is the Passmark single-thread test, where the PRO scores 4,542 and the 9980X scores 4,537, a delta of just 0.1%. The Passmark multithread score is 171,200 for the PRO versus 141,641 for the 9980X, a 20.9% difference.

Where Each One Wins

The PRO 9995WX wins in every scenario that leverages its physical advantages. Any multi-threaded workload that can scale beyond 64 cores will see a significant benefit. The data shows this clearly in compute-heavy tasks like Cinebench multi-core rendering, where it is consistently 13.8% faster. The PRO's wins are even more pronounced in specialized workloads. The 31.5% lead in data encryption and the 25.2% lead in data compression make it the pick for database, archival, and security applications. The 110.7% win in the physics test and the 91.9% win in prime number finding indicate a massive advantage in scientific simulation and number-crunching tasks. The 38% lead in integer math is crucial for financial modeling and general computational workloads. The PRO's eight-channel memory and 128 PCIe lanes are the deciding factors for systems running large datasets that need high bandwidth and multiple accelerators.

The 9980X wins in the context of a desktop workstation where the PRO's extra capabilities are overkill. Its single-threaded performance is effectively identical to the PRO, with only a 0.1% difference in the Passmark single-thread test. This means everyday application responsiveness, web browsing, and lightly-threaded legacy software will feel the same. Its higher base clock of 3.20 GHz might give it a slight edge in latency-sensitive tasks that do not use many cores, although the benchmarks do not show a win. The 9980X is also the winner for a system builder who needs a 350 W TDP part with 80 PCIe lanes and quad-channel memory, which is still a massive amount of bandwidth for most desktop users. The launch MSRP is the clearest differentiator; the 9980X at $4999 is less than half the price of the PRO 9995WX at $11700, making it a far more accessible entry point into the high-core-count Threadripper platform.
