AMD Ryzen AI 9 HX PRO 475 vs Intel Core 9 270H Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive overall advantage for the AMD Ryzen AI 9 HX PRO 475. Out of 11 direct benchmark comparisons, the AMD processor wins 10, with only a single victory for the Intel Core 9 270H. The average benchmark score confirms the gap: AMD scores 74,496 against Intel's 38,335, a difference that places the two chips in different performance tiers entirely.

The largest margin comes in extended instruction testing, where AMD delivers a score of 31,969 against Intel's 20,079. That is a 59.2% advantage, the widest gap in any measured workload. Data compression shows a similar story, with AMD at 461,650 versus Intel's 333,785, a 38.3% lead. Random string sorting also favors AMD heavily, 48,894 to 36,867, a 32.6% difference. Integer math follows at 29.9%, with AMD scoring 126,829 against Intel's 97,654.

Multithreaded performance, often the headline figure for productivity comparisons, favors AMD by 26.8%. The PassMark multithread score is 36,487 for AMD and 28,764 for Intel. This aligns with the core and thread counts: AMD fields 12 cores and 24 threads, while Intel uses 14 cores and 20 threads. The extra threads on AMD's side translate into measurable throughput gains in parallel workloads.

Single-thread performance is closer but still favors AMD. The PassMark single-thread score shows AMD at 4,301 versus Intel at 3,944, a 9.1% edge. This is notable because Intel's boost clock is higher, 5.80 GHz against AMD's 5.20 GHz, yet AMD still wins in single-threaded throughput. The architectural efficiency of Zen 5 appears to offset the raw clock disadvantage.

Other workloads show narrower but consistent AMD wins. Floating-point math goes to AMD by 13.1%, with scores of 79,887 and 70,640. Prime number finding favors AMD by 16.1%, 130 to 112. Data encryption shows a 19.4% lead for AMD, 23,132 to 19,369.

The sole Intel victory comes in the physics benchmark. Intel scores 1,966 against AMD's 1,877, a 4.5% margin. This is the only test in the entire set where Intel outperforms AMD, and the margin is modest compared to AMD's wins in other categories.

For context on overall placement, AMD sits at the 94th percentile of all CPUs in the database, while Intel sits at the 86th percentile. AMD's nearest rivals include the AMD Ryzen 9 9950X at 74,640 average score (0.2% ahead of AMD), the AMD Ryzen 7 PRO 9745 at 74,761 (0.4% ahead), and the Intel Core Ultra 9 285 at 75,488 (1.3% ahead). Intel's nearest rivals are substantially lower: the Intel Core Ultra 9 285H at 38,312 average score (0.1% behind Intel), the Intel Xeon w3-2525 at 38,392 (0.1% ahead), and the AMD Ryzen 7 250 at 38,221 (0.3% behind Intel).

Where Each One Wins

The data maps cleanly onto workload categories. AMD dominates compute-heavy tasks: integer math, floating-point math, extended instructions, and data compression all show double-digit leads. These are the workloads that benefit from high instruction throughput and efficient core design. The 59.2% extended instruction lead suggests AMD's Zen 5 handles advanced instruction sets with significantly better efficiency than Intel's Raptor Lake architecture.

AMD also wins in memory-sensitive operations. Data compression depends on both cache and memory bandwidth; AMD's 16 MB L3 cache and 89.6 GB/s memory bandwidth support this result. Random string sorting, which involves frequent data movement, also favors AMD by 32.6%. Encryption workloads, which rely on dedicated instruction paths, show a 19.4% AMD advantage.

Intel's physics benchmark win, 1,966 versus 1,877, represents the only scenario where Intel leads. Physics calculations often favor higher sustained clock speeds and specific scheduling behaviors. Intel's 14 cores, even with fewer threads, provide a wider physical core pool for this particular workload. The 4.5% margin is real but isolated.

For multithreaded productivity, AMD's 26.8% lead in the PassMark multithread test is the headline figure. This suggests that rendering, video encoding, and compilation workloads will generally favor AMD. The thread count advantage, 24 versus 20, compounds with AMD's per-core efficiency to produce a substantial gap.

Single-thread performance, while closer, still favors AMD by 9.1%. This covers typical desktop responsiveness, office applications, and lightly threaded legacy software. Even with Intel's higher boost clock of 5.80 GHz, AMD's 5.20 GHz maximum does not prevent a win in this category.

Architecture Differences

The two processors come from fundamentally different design philosophies. AMD uses the Zen 5 architecture on a 4 nm TSMC process node, with the codename Gorgon Point. Intel uses the Raptor Lake architecture, specifically the Raptor Lake-H variant, on a 10 nm Intel process node. The process node difference alone explains part of the efficiency gap: 4 nm versus 10 nm is a significant manufacturing advantage for AMD.

AMD's cache layout consists of 80 KB L1 per core, 1 MB L2 per core, and 16 MB L3. Intel also uses 80 KB L1 per core but doubles the L2 to 2 MB per core and provides 24 MB of shared L3. Intel's larger L3 cache, 24 MB versus 16 MB, does not translate into benchmark wins in the recorded data, suggesting AMD's cache efficiency and prefetch behavior compensate for the smaller pool.

Core topology differs as well. AMD provides 12 cores and 24 threads, relying on simultaneous multithreading for the full thread count. Intel provides 14 cores and 20 threads, which implies a hybrid arrangement typical of Raptor Lake with performance and efficiency cores. The thread count difference, 24 versus 20, favors AMD in heavily parallel workloads.

Memory support diverges. AMD supports DDR5 and LPDDR5X with dual-channel bus and a measured 89.6 GB/s bandwidth. Intel supports DDR4 and DDR5, also dual-channel, but the database does not record a bandwidth figure for Intel. AMD also supports ECC memory, while Intel does not. This makes AMD the choice for error-sensitive workloads.

PCIe connectivity differs: AMD provides Gen 4 with 16 CPU lanes, while Intel provides Gen 5 with 8 CPU lanes. The generation advantage goes to Intel, but the lane count advantage goes to AMD. Integrated graphics also differ: AMD uses the Radeon 890M, while Intel uses Iris Xe Graphics with 96 execution units.

The die size for AMD is recorded at 233 mm², while Intel's die size is not recorded. Both processors use their respective sockets: AMD Socket FP8 for AMD, Intel BGA 1744 for Intel. Neither processor has an unlocked multiplier. AMD's part number is 100-000001683, Intel's is SRQ6V.

The Verdict

The benchmark data points consistently toward the AMD Ryzen AI 9 HX PRO 475 for users prioritizing raw compute performance. AMD wins 10 of 11 head-to-head tests, including all major productivity categories: multithread, single-thread, integer math, floating-point math, and data compression. The average score of 74,496 places AMD in a different performance class than Intel's 38,335, and AMD's nearest rivals are all high-end desktop or workstation parts, not mobile chips.

The Intel Core 9 270H has a single win in physics testing, and it does offer a higher boost clock at 5.80 GHz, a larger L3 cache at 24 MB, and PCIe Gen 5 support. Users who specifically need those features, or who require DDR4 memory compatibility, may find Intel suitable. Intel also has a lower TDP in the sense that its recorded 45 W TDP is higher than AMD's 28 W, so Intel does not win on power efficiency as recorded.

For workloads that stress encryption, compression, extended instructions, or general multithreaded throughput, the data shows AMD ahead by margins ranging from 16.1% to 59.2%. The single-thread lead of 9.1% means even lightly threaded applications favor AMD. The physics benchmark aside, there is no recorded category where Intel meaningfully challenges AMD's position.

The database percentile ranking reinforces this: AMD at the 94th percentile versus Intel at the 86th percentile. AMD also supports ECC memory, which Intel does not, making AMD the safer choice for data-integrity-sensitive environments. The release dates differ, with Intel launching in December 2024 and AMD in January 2026, but the recorded performance data does not reflect any advantage for the earlier launch.

Users who need the absolute highest recorded benchmark scores in mobile computing should select the AMD part based on this data. Users who require the specific features Intel offers, such as PCIe Gen 5 or DDR4 support, should verify those needs against the specification table. Otherwise, the benchmark results indicate a clear performance winner.
