Where Each One Wins

The Intel Xeon 6517P is the clear winner for compute-heavy, parallel workloads. Its biggest victory comes in PassMark find prime numbers, where it scores 335 against the AMD's 130 — a 157.7% advantage. Physics calculations also favor Intel heavily, with the Xeon posting 4452 versus 1877, a 137.2% gap. Extended instruction workloads show a 62.3% lead (51891 vs 31969), and floating-point math is 59.6% higher (127497 vs 79887). Data compression and encryption also go to Intel, with 41.5% and 40% deltas respectively. For server tasks like database operations, rendering, or scientific simulation, the Xeon 6517P's 16 cores and 72 MB L3 cache provide an overwhelming throughput advantage.

The AMD Ryzen AI 9 HX PRO 475 wins in exactly one benchmark category, but it is a critical one: single-threaded performance. Its 4301 score in PassMark single-thread testing outstrips the Intel's 3311 by 23%. This translates to faster response in lightly-threaded applications, better day-to-day usability, and superior performance in software that relies on high clock speeds rather than core counts. The AMD chip also benefits from a much lower 28W TDP, making it the only viable choice for fanless or battery-powered systems, though its 12 cores and 16 MB L3 cache still provide respectable multi-threaded capability for a mobile part.

Architecture Differences

The Intel Xeon 6517P is built on Granite Rapids architecture, Intel's 5 nm process, and targets the server/workstation segment with an Intel Socket 4710. It uses a monolithic die design with 16 cores based on the Granite Rapids core, supporting 32 threads. The cache hierarchy is generous: 112 KB L1 per core, 2 MB L2 per core, and 72 MB shared L3. Memory support is DDR5 over an eight-channel bus, delivering 409.6 GB/s. PCIe connectivity is Gen 5 with 88 lanes. This processor has no integrated graphics, as it is designed strictly for compute tasks.

The AMD Ryzen AI 9 HX PRO 475 uses the Zen 5 architecture on a 4 nm TSMC process, with the codename Gorgon Point. It is a mobile part on AMD Socket FP8, featuring a hybrid design of Zen 5 and Zen 5c cores totaling 12 cores and 24 threads. The die size is 233 mm². L1 cache is 80 KB per core, L2 is 1 MB per core, and L3 is 16 MB. Memory support includes both DDR5 and LPDDR5X over a dual-channel bus, providing 89.6 GB/s. PCIe is Gen 4 with 16 lanes. Unlike the Intel part, it includes an integrated Radeon 890M GPU, making it a complete system-on-chip for mobile devices.

Specification Differences

The two processors diverge sharply on nearly every specification. The Intel Xeon 6517P has 16 cores and 32 threads, while the AMD Ryzen AI 9 HX PRO 475 has 12 cores and 24 threads. Base clocks differ significantly: 3.20 GHz for Intel versus 2.00 GHz for AMD. Boost clocks favor AMD at 5.20 GHz against Intel's 4.20 GHz. TDP is a massive differentiator at 190 for Intel versus 28 for AMD. Sockets are incompatible (Intel Socket 4710 vs AMD Socket FP8). Process nodes differ (5 nm Intel vs 4 nm TSMC). Cache sizes are larger on Intel, with 72 MB L3 versus 16 MB. Memory bandwidth is 409.6 GB/s versus 89.6 GB/s, with Intel using eight-channel DDR5 and AMD using dual-channel DDR5/LPDDR5X. PCIe lanes differ (88 Gen 5 lanes vs 16 Gen 4 lanes). The AMD part includes integrated Radeon 890M graphics; the Intel has N/A. Release dates also differ, with Intel launching on 2025-02-23 and AMD on 2026-01-04.

Head-to-Head Benchmarks

The head-to-head results paint a lopsided picture in favor of the Intel Xeon 6517P. In PassMark data compression, Intel scores 653338 against AMD's 461650, a 41.5% win. Data encryption follows suit: 32385 vs 23132, a 40% advantage. Extended instructions show the widest gap among compute tests, with Intel at 51891 and AMD at 31969, a 62.3% delta. The find prime numbers test is the most dramatic: Intel's 335 crushes AMD's 130, a 157.7% difference. Floating-point math favors Intel at 127497 vs 79887 (59.6%), integer math at 162671 vs 126829 (28.3%), and multithread performance at 49786 vs 36487 (36.4%). Physics tests show Intel at 4452 against AMD's 1877, a 137.2% lead. Random string sorting goes to Intel 67480 vs 48894, a 38% margin.

The AMD Ryzen AI 9 HX PRO 475 wins the single-thread tests. In both passmark_single_thread and passmark_singlethread, AMD scores 4301 versus Intel's 3311, a 23% advantage. This is the only category where AMD leads, but it highlights the architectural strength of Zen 5's high boost clock of 5.20 GHz. Despite losing 9 of 11 benchmarks, AMD's average benchmark score of 74496 actually exceeds Intel's 72350, driven by the fact that AMD's benchmark suite includes fewer multi-threaded tests and its single-thread dominance carries more weight in the average calculation. Intel's nearest rival is the Intel Xeon 6724P (avgScore 72396, deltaPct -0.1), while AMD's closest competitor is the AMD Ryzen 9 9950X (avgScore 74640, deltaPct -0.2). Both processors rank in the 94th percentile of all CPUs, though they achieve this status through opposite means: raw parallel power versus exceptional single-core efficiency.
