Architecture Differences

The architectural divide between these two processors is substantial, reflecting a five-year gap in design philosophy. The Intel Xeon 6741P is built on the Granite Rapids architecture, manufactured on a 5 nm process by Intel, with a die size of 2x 598 mm². In contrast, the AMD Ryzen Threadripper PRO 3995WX uses the Zen 2 architecture, fabricated by TSMC on a 7 nm process, with a die size of 8x 74 mm² and 30,400 million transistors. This node advantage translates directly into higher clock speeds for the Intel part: it runs at 2.50 GHz base and 3.80 GHz boost, while the AMD part operates at 2.70 GHz base and 4.20 GHz boost. Despite the lower boost clock, the Intel chip’s newer process delivers superior single-thread performance in every benchmark.

Cache hierarchies also differ markedly. The Intel Xeon 6741P allocates 112 KB of L1 and 2 MB of L2 per core, with a massive 288 MB of shared L3 cache. The AMD Ryzen Threadripper PRO 3995WX has smaller per-core caches — 64 KB L1 and 512 KB L2 — but offers 256 MB of L3. In memory support, the Intel part uses DDR5 with an eight-channel bus and 409.6 GB/s bandwidth, whereas the AMD part uses DDR4 with an eight-channel bus and 204.8 GB/s bandwidth. PCIe connectivity also differs: the Xeon 6741P provides Gen 5 with 136 lanes, while the Threadripper PRO 3995WX provides Gen 4 with 128 lanes. Both support ECC memory, but the Intel part targets the server/workstation market segment, while the AMD part is classified as desktop.

Head-to-Head Benchmarks

The benchmark data reveals a pattern of Intel dominance in compute-intensive tasks, with AMD securing specific data-handling victories. In Cinebench R15, R20, and R23 multicore tests, the Intel Xeon 6741P wins with a consistent 19.9% margin across all three versions. The single-core results are nearly identical in percentage terms: the Xeon 6741P leads by 20% in both R15 and R20, and by 19.9% in R23. This uniformity suggests a fundamental architectural efficiency advantage for the Intel part rather than workload-specific tuning.

PassMark results show a more varied picture. The Intel Xeon 6741P wins extended instructions by 34.1%, floating point math by 29.1%, and single-thread performance by 23.1%. Its most dramatic victory is in physics, where it scores 13,890 against the AMD part’s 5,498, a 152.6% delta. The find prime numbers test is similarly lopsided: Intel scores 1,242 versus AMD’s 566, a 119.4% advantage. These results indicate that the Intel architecture handles complex mathematical and physics simulations with far greater efficiency.

The AMD Ryzen Threadripper PRO 3995WX, despite losing 13 of 17 benchmarks, carves out a niche in memory-heavy operations. It wins data compression by 1.4% (1,841,292 vs 1,816,408), random string sorting by 6% (188,574 vs 177,322), and integer math by 6.5% (490,116 vs 458,058). Its most significant victory is in data encryption, where it scores 124,433 versus Intel’s 89,746, a 27.9% advantage. These wins suggest that the AMD part’s higher core count (64 vs 48) provides an edge in parallel data manipulation tasks, despite the Intel part’s superior per-core performance.

The PassMark multithread test shows the Xeon 6741P ahead by 19.9% (100,660 vs 83,928), reinforcing the Cinebench results. Overall, the data indicates that the Intel Xeon 6741P is faster in most general-purpose and compute workloads, while the AMD part’s strengths are confined to specific data processing scenarios.

The Verdict

The benchmark data supports a clear performance hierarchy. The Intel Xeon 6741P is the superior processor for the vast majority of workloads, leading in 13 of 17 head-to-head tests. Its advantages are most pronounced in physics (152.6% faster), prime number finding (119.4% faster), and extended instructions (34.1% faster), making it the obvious choice for scientific computing, engineering simulations, and any application that relies on heavy mathematical computation. The Cinebench multicore results, where Intel leads by approximately 20% across all versions, further cement its position for rendering and content creation.

The AMD Ryzen Threadripper PRO 3995WX is not without merit. Its wins in data encryption (27.9% faster) and integer math (6.5% faster) suggest it handles certain data processing and security workloads more effectively. The 64-core configuration may also appeal to users who run highly parallel, memory-bound tasks that benefit from the additional threads. However, the Intel part’s 19.9% lead in the PassMark multithread test indicates that core count alone does not guarantee overall throughput.

For server and workstation deployments where compute density and single-thread performance are critical, the Intel Xeon 6741P is the data-driven choice. Its 5 nm process, DDR5 memory support, and 409.6 GB/s bandwidth provide a modern foundation that outperforms the older AMD platform. The AMD part, with its 2020 release date and DDR4 memory, remains competitive only in specific niches. Users prioritizing encryption or data sorting workloads may prefer the Threadripper PRO 3995WX, but the Xeon 6741P’s broader benchmark dominance makes it the default recommendation for general high-performance computing.
