AMD Ryzen AI 9 HX PRO 475 vs Intel Processor N250 Comparison

Where Each One Wins

The AMD Ryzen AI 9 HX PRO 475 is the clear performance leader across every measured workload category. The database shows this processor holding the 94th percentile among all CPUs, with an average benchmark score of 74,496. Its nearest rivals include the AMD Ryzen 9 9950X at 74,640 (0.2% faster), the AMD Ryzen 7 PRO 9745 at 74,761 (0.4% faster), and the AMD EPYC 4545P at 75,373 (1.2% faster). The Intel Processor N250, by contrast, sits at the 50th percentile with no recorded benchmark scores in the database, making direct comparisons impossible from measured data alone.

The AMD part wins decisively in multi-threaded throughput, single-thread responsiveness, and every specialized compute test. Its 12 cores and 24 threads provide substantial parallelism for rendering, compilation, and data processing tasks. The Intel Processor N250 offers 4 cores and 4 threads, which places it in a fundamentally different performance class. The N250's strengths lie elsewhere: it carries a 6-watt TDP, making it suited for fanless or passively cooled designs where power draw is the primary constraint. The AMD Ryzen AI 9 HX PRO 475 has a 28-watt TDP, which allows far higher sustained performance but requires active cooling and a larger thermal solution.

Architecture Differences

The AMD Ryzen AI 9 HX PRO 475 uses a hybrid Zen 5 / Zen 5c configuration under the Gorgon Point codename, built on TSMC's 4 nm process with a 233 mm² die size. This combines high-performance Zen 5 cores with dense Zen 5c cores, enabling 12 cores and 24 threads within a 28-watt envelope. The Intel Processor N250 uses the Twin Lake architecture, based on Alder Lake-N, fabricated on Intel's 10 nm node. It uses four Gracemont efficiency cores without hyper-threading, giving 4 threads total.

Cache configurations differ substantially. The AMD chip allocates 80 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Intel part provides 96 KB of L1 per core, 2 MB of shared L2, and 6 MB of shared L3. The AMD processor's per-core L2 design scales with core count, while Intel's shared L2 pool serves all four cores. The AMD part also supports ECC memory, a feature absent from the Intel N250.

Memory and I/O capabilities split sharply. The AMD Ryzen AI 9 HX PRO 475 uses dual-channel DDR5 or LPDDR5X with 89.6 GB/s bandwidth. The Intel Processor N250 supports DDR4, DDR5, or LPDDR5 in single-channel mode with 38.4 GB/s bandwidth. PCIe connectivity favors AMD as well: Gen 4 with 16 CPU lanes versus Intel's Gen 3 with 9 CPU lanes. Integrated graphics differ too, with AMD's Radeon 890M versus Intel's UHD Graphics 730. Both are mobile processors, both are currently active in production, and neither has an unlocked multiplier.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between these two processors. The AMD Ryzen AI 9 HX PRO 475 has extensive PassMark test results; the Intel Processor N250 has none recorded. This absence of data means the comparison must proceed from the AMD part's absolute scores and the architectural specifications of both chips.

The AMD Ryzen AI 9 HX PRO 475 achieves a PassMark multi-thread score of 36,487. Its single-thread score is 4,301. Integer math posts 126,829, while floating-point math reaches 79,887. Data compression scores 461,650, data encryption scores 23,132, and extended instructions (SIMD) score 31,969. Random string sorting finishes at 48,894, and the physics test records 1,877. Prime number finding posts a score of 130.

These numbers indicate a processor capable of handling heavy parallel workloads with ease. The multi-thread score of 36,487 places it in the top tier of mobile processors, rivaling desktop-class parts. The single-thread score of 4,301 confirms strong per-core performance from the Zen 5 architecture, which matters for latency-sensitive applications like spreadsheets, web browsing, and light gaming. The data encryption score of 23,132 suggests robust AES acceleration, useful for VPNs and encrypted storage. The extended instructions score of 31,969 indicates solid AVX-512 or similar SIMD throughput for scientific and engineering software.

The Intel Processor N250 has no benchmark entries, so no score exists to compare directly. Its 4 cores and 4 threads, combined with a 3.80 GHz boost clock, suggest it will trail the AMD part substantially in multi-threaded workloads. The N250's single-thread performance may be competitive given its boost clock, but without measured data, the database cannot confirm this.

The Verdict

From the recorded data, the AMD Ryzen AI 9 HX PRO 475 is the only option for users needing serious compute performance. Its 94th-percentile ranking, 12 cores, 24 threads, and extensive benchmark scores demonstrate capability across every tested category. The Intel Processor N250, with a 50th-percentile ranking and no benchmark scores, cannot be recommended for performance-sensitive tasks based on the available evidence.

The N250's 6-watt TDP gives it a clear niche: ultra-low-power designs, passive cooling, and battery-critical applications. For a thin-and-light laptop designed for basic productivity, media playback, or as a low-cost secondary machine, the N250's power efficiency is its defining attribute. The AMD part demands 28 watts, which is still modest for a 12-core processor, but it requires active cooling and a larger battery to sustain performance.

Users who prioritize multi-threaded throughput, memory bandwidth, PCIe connectivity, or ECC support should select the AMD Ryzen AI 9 HX PRO 475. Users who prioritize minimal power draw above all else, and who accept limited compute capability, may consider the Intel Processor N250. The data does not support any other conclusion.
