AMD Ryzen Threadripper PRO 9955WX vs Intel Core 9 273PQE Comparison

The benchmark database shows a clear hierarchy between the AMD Ryzen Threadripper PRO 9955WX and the Intel Core 9 273PQE. Across 17 head-to-head tests, the AMD processor claims 15 victories, while the Intel part wins 2. The decisive factor is the AMD chip’s dominant multicore throughput, which outstrips the Intel part by significant margins in nearly every workload category.

Head-to-Head Benchmarks

The most striking result is in Cinebench, where the AMD Ryzen Threadripper PRO 9955WX posts a consistent 51.8% advantage across all six tests. In Cinebench R23 multicore, the AMD scores 59494 against Intel’s 39190, a gap of 20304 points. Single-core results follow the same pattern: Cinebench R23 single-core shows 8399 for AMD versus 5532 for Intel, a 51.8% delta. The identical percentage across R15, R20, and R23 indicates a fixed performance ratio, not a workload-specific anomaly.

PassMark results reinforce the multicore dominance. The AMD part wins data compression with 920954 points against 585752, a 57.2% lead. Data encryption shows 44389 versus 29636, a 49.8% delta. The largest single margin appears in extended instructions, where AMD scores 76363 compared to Intel’s 38743, a 97.1% difference. Random string sorting also shows a wide gap: 99813 versus 53167, an 87.7% delta. Prime number finding favors AMD by 70.2% (337 versus 198). Integer math shows a 43.4% lead (236120 versus 164629), while floating point math is closer at 24.4% (156215 versus 125546). Multithread performance shows 67035 versus 46107, a 45.4% margin, and physics tests show 4156 versus 2754, a 50.9% delta.

The Intel Core 9 273PQE wins only in PassMark single-thread tests. The score is 4573 against AMD’s 4530, a 0.9% margin. That result appears in both the passmark_single_thread and passmark_singlethread entries, confirming it as a genuine, if narrow, advantage. This indicates Intel’s higher boost clock, 5.90 GHz versus 5.40 GHz, gives it a slight edge when only one core is active. However, the margin is small enough that it does not offset AMD’s multicore superiority.

Where Each One Wins

The AMD Ryzen Threadripper PRO 9955WX wins every heavily threaded workload category in the database. This includes Cinebench renders, data compression, encryption, extended instruction sets, prime number calculations, integer math, floating point math, multithread throughput, physics simulations, and random string sorting. The data shows the AMD part is built for parallel workloads where all cores engage simultaneously. The 51.8% Cinebench margin specifically indicates a consistent advantage in rendering tasks, which scale directly with core count and thread count.

The Intel Core 9 273PQE wins only in single-threaded PassMark tests. This makes it suitable for lightly threaded applications where a single core carries the load. The 0.9% margin is modest, but it does demonstrate that Intel’s architecture can match or slightly exceed AMD’s per-core performance in specific conditions. Workloads that depend on one core, such as certain legacy software or lightly threaded user interfaces, would see a marginal benefit from the Intel part.

The overall picture from the data is clear: AMD dominates in throughput, Intel has a narrow single-core lead. For users running parallel jobs, the AMD part is the obvious choice. For users with strictly single-threaded tasks, the Intel part offers a slight edge, but the margin is too small to be decisive in most real-world scenarios.

Architecture Differences

The AMD Ryzen Threadripper PRO 9955WX uses the Zen 5 architecture on a 4 nm process node from TSMC. The Intel Core 9 273PQE uses a 10 nm process node from Intel’s own foundry. The AMD part has 16 cores and 32 threads, while the Intel part has 12 cores and 24 threads. This 4-core and 8-thread difference explains most of the multicore performance gap.

Cache configurations differ substantially. The AMD part has 64 KB of L1 per core, 1 MB of L2 per core, and 64 MB of L3 cache. The Intel part has 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. The AMD chip’s larger total L3, 64 MB versus 36 MB, provides more headroom for data-heavy workloads. The Intel chip has larger per-core L1 and L2, but that does not compensate for the smaller L3 in multithreaded scenarios.

Memory architecture shows a major divergence. The AMD part supports DDR5 memory with an eight-channel bus and 409.6 GB/s bandwidth. The Intel part supports both DDR4 and DDR5 but uses a dual-channel bus with 89.6 GB/s bandwidth. The fourfold difference in memory channels and the 4.5x difference in bandwidth directly affect data-intensive tasks. The AMD part’s PCIe implementation also differs: it offers Gen 5 with 128 lanes (CPU only), while the Intel part offers Gen 5 with 16 lanes (CPU only). The AMD part has no integrated graphics, while the Intel part includes UHD Graphics 770.

The AMD part’s production status is Active, with a release date of 2025-07-22. The Intel part is also Active, with a release date of 2026-03-08. The AMD part’s generation is listed as Ryzen Threadripper (Zen 4 (Storm Peak)), while the Intel part’s generation is Core 9 (Bartlett Lake). The AMD codename is Shimada Peak, and the Intel codename is Bartlett Lake.

The Verdict

The data directs a clear split. The AMD Ryzen Threadripper PRO 9955WX is the choice for workloads that use many threads. Its 51.8% lead in Cinebench tests, 57.2% lead in data compression, and 45.4% lead in multithread throughput confirm it excels at rendering, data processing, and parallel computation. The eight-channel memory bus and 409.6 GB/s bandwidth support this role, as does the 128-lane PCIe Gen 5 implementation for expansion-heavy systems.

The Intel Core 9 273PQE is the choice only for strictly single-threaded tasks. Its 0.9% PassMark single-thread win shows a marginal edge, and its 5.90 GHz boost clock gives it the highest peak frequency in this comparison. The 125-watt TDP also makes it far lighter on power draw. However, the data shows no other category where Intel takes the lead.

For most professional workloads, the AMD part’s multicore dominance is decisive. The 97.1% extended instructions margin and 87.7% random string sorting margin show that even specialized instruction sets run faster on AMD. The Intel part’s single-thread win is real but narrow, and it does not translate into an overall performance advantage in any multicore benchmark. The recorded data indicates that the AMD Ryzen Threadripper PRO 9955WX is the stronger processor for all but the most single-thread-focused use cases.
