AMD Ryzen 7 PRO 9745 vs Intel Xeon 6517P Comparison

The Intel Xeon 6517P and AMD Ryzen 7 PRO 9745 represent two fundamentally different approaches to server and workstation processing. The data reveals a stark split: the Intel part dominates nearly every multi-threaded and specialized workload, while the AMD chip claims a decisive victory in single-thread performance. This head-to-head comparison shows 11 benchmark results, with the Intel Xeon 6517P winning 9 and the AMD Ryzen 7 PRO 9745 winning 2, yet the AMD processor holds a higher overall percentile ranking at 95 versus Intel’s 94.

Head-to-Head Benchmarks

The most dramatic gap appears in the Passmark physics test, where the Intel Xeon 6517P scores 4452 against AMD’s 2026, a staggering 119.7% advantage. This suggests the Intel architecture handles complex physical simulations with far greater efficiency, likely due to its higher core count and larger cache hierarchy. Similarly, in prime number finding, Intel leads with 335 versus 188, a 78.2% delta that indicates superior integer processing capabilities in mathematically intensive tasks.

Floating-point math shows another clear Intel victory: 127497 versus 82461, representing a 54.6% lead. This pattern continues across data compression (653338 vs 457211, 42.9% ahead), encryption (32385 vs 22848, 41.7% ahead), and extended instructions (51891 vs 36800, 41% ahead). The Intel Xeon 6517P also wins in random string sorting by 37.1%, integer math by 31%, and the Passmark multithread test by 30.3%, scoring 49786 against AMD’s 38201.

The single exception to Intel’s dominance is striking. In Passmark single-thread tests, the AMD Ryzen 7 PRO 9745 scores 4624 versus Intel’s 3311, a 28.4% advantage. This is the only category where AMD wins, but it is a significant one. The deltaPct is negative for Intel in this test, indicating that the AMD processor delivers substantially better performance when only one core is active. This single-thread gap likely stems from the AMD chip’s higher boost clock of 5.40 GHz compared to Intel’s 4.20 GHz, combined with the newer Zen 5 architecture.

Architecture Differences

The two processors diverge fundamentally in their core configurations. The Intel Xeon 6517P packs 16 cores and 32 threads, while the AMD Ryzen 7 PRO 9745 offers just 8 cores and 16 threads. This 2x core advantage explains much of Intel’s multi-threaded dominance. The Intel chip draws on Granite Rapids architecture, built on Intel’s 5 nm process, whereas AMD uses Granite Ridge with Zen 5 cores on TSMC’s 4 nm node. The AMD processor contains 8,315 million transistors on a 70.6 mm² die, while the Intel part’s transistor count and die size are not listed.

Cache configurations tell a similar story of scale. Intel provides 112 KB of L1 cache per core, 2 MB of L2 per core, and a massive 72 MB shared L3 cache. AMD offers 80 KB L1 per core, 1 MB L2 per core, and 32 MB shared L3. Intel’s total cache capacity is substantially larger, which likely contributes to its wins in data-heavy workloads like compression and sorting. The memory subsystem also differs: Intel supports eight-channel DDR5 with 409.6 GB/s bandwidth, while AMD uses dual-channel DDR5 with 89.6 GB/s. This 4.5x bandwidth advantage gives Intel a clear edge in memory-intensive applications.

PCIe lanes also favor Intel, with 88 Gen 5 lanes versus AMD’s 24 Gen 5 lanes. Both support ECC memory, and neither has an unlocked multiplier. The AMD chip includes integrated Radeon Graphics, while the Intel Xeon 6517P has N/A for integrated graphics. Sockets differ completely: Intel uses Socket 4710, AMD uses AM5. The Intel chip has a launch MSRP of $1195, while AMD’s launch MSRP is not provided.

Where Each One Wins

The Intel Xeon 6517P is the clear choice for workloads that scale with core count and memory bandwidth. Data compression, encryption, and extended instruction sets all show Intel leading by over 40%. Physics simulations show the largest gap at 119.7%, indicating that scientific computing and engineering workloads would strongly favor the Intel part. The 16-core, 32-thread configuration combined with 72 MB of L3 cache and 409.6 GB/s memory bandwidth makes it suitable for virtualized environments, database servers, and any application that can utilize many threads simultaneously. The Passmark multithread score of 49786 versus 38201 reinforces this conclusion.

The AMD Ryzen 7 PRO 9745 wins exclusively in single-thread performance, with a 28.4% advantage. This makes it the better option for lightly threaded applications, legacy software that doesn’t scale across cores, or workloads where per-core speed is paramount. Its higher boost clock of 5.40 GHz and newer Zen 5 architecture deliver the best possible performance for tasks like single-threaded scripting, certain database queries, or real-time processing where low latency on one core matters more than aggregate throughput. The AMD chip’s lower TDP of 65 watts versus Intel’s 190 watts also suggests it can maintain high clocks without the same thermal demands, though the data does not directly measure power efficiency.

The Verdict

The benchmark data presents a clear choice based on workload characteristics. The Intel Xeon 6517P wins 9 of 11 head-to-head tests and achieves decisive victories in every multi-threaded category, with leads ranging from 30.3% to 119.7%. Its architecture with 16 cores, 32 threads, 72 MB of L3 cache, and eight-channel memory is purpose-built for high-throughput server environments. Any application that can parallelize across cores will see substantial benefits from the Intel processor.

The AMD Ryzen 7 PRO 9745, despite having half the cores and threads, still achieves a higher average benchmark score of 74761 compared to Intel’s 72350, and a higher percentile ranking of 95 versus 94. This is remarkable given its smaller footprint. Its 28.4% single-thread advantage makes it the superior choice for single-core-bound applications. The data shows that for users who prioritize raw single-thread speed or run software that cannot utilize more than a few cores, the AMD processor is clearly better. However, for nearly every multi-threaded or memory-intensive workload, the Intel Xeon 6517P is the definitive winner.
