AMD Ryzen AI 9 HX PRO 475 vs Intel Xeon 6511P Comparison

The Verdict

The benchmark data draws a clear line between two very different compute platforms. The AMD Ryzen AI 9 HX PRO 475 and the Intel Xeon 6511P both sit in the 94th percentile of all CPUs, but they achieve that standing through opposite strengths. The AMD part is a mobile processor with a single-thread advantage that is massive in percentage terms, while the Intel Xeon is a server-class chip that dominates every multi-threaded workload in the recorded tests. The data shows 9 benchmark wins for the Intel Xeon 6511P against 2 wins for the AMD Ryzen AI 9 HX PRO 475, but the nature of those wins matters more than the count.

For users running heavily threaded server or workstation applications, the Intel Xeon 6511P is the clear pick. Its advantage in data compression is 28%, its lead in physics calculations is 59.9%, and its multithread score is 20.1% higher. The Xeon also holds a 37% edge in extended instructions, which points to strong SIMD and vectorized workload performance. Anyone targeting enterprise databases, scientific computing, or content rendering should look at the Xeon first.

For users prioritizing responsiveness in single-threaded tasks, the AMD Ryzen AI 9 HX PRO 475 is the better choice. Its PassMark single-thread score of 4301 beats the Xeon's 2545 by a remarkable 69%. This is a mobile processor with a 5.20 GHz boost clock, and the data shows it handles latency-sensitive, lightly threaded work with far more agility. The Ryzen also brings integrated Radeon 890M graphics, which the Xeon lacks entirely, making it a self-contained solution for compact systems.

The average benchmark scores tell a nuanced story. The Ryzen posts an average of 74496 across its recorded tests, while the Xeon averages 71051. That puts the AMD part in the company of the AMD Ryzen 9 9950X (delta of -0.2%) and the AMD Ryzen 7 PRO 9745 (delta of -0.4%), while the Xeon's closest rival is the Intel Core Ultra 7 265K (delta of 0.2%). The Ryzen's higher average comes from its enormous single-thread score, but the Xeon's consistency across multi-threaded tests makes it the more balanced performer for sustained parallel loads.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI 9 HX PRO 475 uses the Zen 5 architecture under the codename Gorgon Point, built on a 4 nm process at TSMC. It is a mobile part with 12 cores and 24 threads, and its generation is listed as Ryzen AI PRO 400 (Zen 5 / Zen 5c), indicating a hybrid core arrangement within the Zen 5 family. The Intel Xeon 6511P uses the Granite Rapids architecture, also its codename, built on a 5 nm process at Intel's own foundry. It is a server and workstation part with 16 cores and 32 threads, belonging to the Xeon 6 (Granite Rapids-SP) generation.

Cache hierarchies differ significantly. The AMD processor provides 80 KB of L1 cache per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. The Intel Xeon provides 112 KB of L1 per core, 2 MB of L2 per core, and a much larger 72 MB of shared L3 cache. That larger L3 pool on the Xeon is a substantial advantage for workloads with large working sets that benefit from on-die data reuse.

Memory architecture also diverges sharply. The Ryzen supports DDR5 and LPDDR5X over a dual-channel bus, yielding a memory bandwidth of 89.6 GB/s. The Xeon supports DDR5 over an eight-channel bus, delivering 409.6 GB/s of memory bandwidth. That is nearly 4.6 times the bandwidth, which is decisive for memory-bound server tasks. Both processors support ECC memory, but the PCIe connectivity differs: the Ryzen offers PCIe Gen 4 with 16 lanes (CPU only), while the Xeon offers PCIe Gen 5 with 136 lanes (CPU only), a massive I/O expansion difference.

The physical and power profiles are also distinct. The Ryzen is a mobile chip with a 28 W TDP, a 2.00 GHz base clock, and a 5.20 GHz boost clock. The Xeon has a 150 W TDP, a 2.30 GHz base clock, and a 4.20 GHz boost clock. The Ryzen uses AMD Socket FP8, while the Xeon uses Intel Socket 4710. The Ryzen's die size is listed at 233 mm², while the Xeon's die size is not recorded in the database. Neither processor has an unlocked multiplier.

Specification Differences

The recorded specifications show several clear points of divergence between the two parts. Core count is the first major difference: the AMD Ryzen AI 9 HX PRO 475 has 12 cores and 24 threads, while the Intel Xeon 6511P has 16 cores and 32 threads, a 33% core advantage for the Xeon. Clock speeds also differ in direction: the Ryzen has a lower base clock of 2.00 GHz but a higher boost clock of 5.20 GHz, while the Xeon has a higher base clock of 2.30 GHz but a lower boost clock of 4.20 GHz.

Thermal design power is radically different, with the Ryzen at 28 W and the Xeon at 150 W. Process node differences show the Ryzen on a 4 nm TSMC process versus the Xeon on a 5 nm Intel process. Cache amounts differ across all levels, with the Xeon offering larger per-core L1 and L2 allocations plus a substantially larger L3 cache. Memory support differs in channel count and bandwidth, as detailed previously.

The integrated graphics situation is a key differentiator: the Ryzen includes Radeon 890M, while the Xeon has no integrated graphics. PCIe generation and lane counts differ, with the Ryzen at Gen 4 with 16 lanes and the Xeon at Gen 5 with 136 lanes. The market segments reflect this: the Ryzen is classified as Mobile, the Xeon as Server/Workstation. Release dates also differ, with the Ryzen listed as 2026-01-04 and the Xeon as 2025-02-23. The Xeon has a launch MSRP of $815, while the Ryzen has no recorded launch MSRP. Both parts are listed as Active in production status, and both support ECC memory.

Head-to-Head Benchmarks

The head-to-head data is overwhelmingly in favor of the Intel Xeon 6511P for multi-threaded and compute-heavy tasks. The largest margin for the Xeon comes in the PassMark physics test, where it scores 4678 against the Ryzen's 1877, a 59.9% advantage. That is an enormous gap and indicates the Xeon's core count and cache configuration are far better suited to physics simulations and similar parallel workloads.

The Xeon also wins decisively in the PassMark find prime numbers test, scoring 308 versus the Ryzen's 130, a 57.8% difference. The extended instructions test shows a 37% lead for the Xeon (50730 versus 31969), and the floating point math test shows a 37.2% lead (127307 versus 79887). Data compression is another clear Xeon win: 640808 versus 461650, a 28% margin. Data encryption favors the Xeon by 26.4% (31429 versus 23132), and random string sorting favors it by 27.9% (67809 versus 48894). Integer math goes to the Xeon by 22% (162524 versus 126829), and the multithread test goes to the Xeon by 20.1% (45687 versus 36487).

The AMD Ryzen AI 9 HX PRO 475's wins are concentrated in single-thread performance, and they are equally decisive in the opposite direction. The PassMark single-thread test shows the Ryzen at 4301 versus the Xeon at 2545, a 69% advantage for the AMD part. This same result appears under both the single_thread and singlethread test names, confirming the finding. The Ryzen's high boost clock of 5.20 GHz likely drives this dominance, and the data suggests it will excel in applications that rely on low-latency, single-thread execution.

The overall picture from the head-to-head table is that the Xeon wins 9 of 11 recorded comparisons, with the Ryzen winning the remaining 2. The magnitude of the Xeon's multi-threaded wins is generally larger than the Ryzen's single-thread win in terms of raw score differences, though the 69% single-thread margin is the most dramatic percentage swing in either direction. The average benchmark scores temper this picture slightly, with the Ryzen's overall average of 74496 exceeding the Xeon's 71051, because the single-thread score carries outsized weight in that aggregate measure. For practical purposes, the choice depends on workload type: the Xeon for throughput, the Ryzen for responsiveness.
