AMD Ryzen AI 9 HX 375 vs Intel Core 9 270H Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive overall victory for the AMD Ryzen AI 9 HX 375, which wins 10 of the 15 recorded head-to-head comparisons. The Intel Core 9 270H takes 5 wins, but the magnitude of AMD's victories is consistently larger. The most dramatic difference appears in PassMark extended instructions, where the AMD part scores 29,269 against Intel's 20,079, a 45.8% advantage. This indicates a substantial lead in workloads that leverage advanced CPU instruction sets.

Cinebench multi-core results reinforce the AMD lead. In Cinebench R23 multi-core, the Ryzen AI 9 HX 375 scores 21,812 versus 18,000 for the Intel part, a 21.2% gap. The older Cinebench R15 multi-core test shows an even larger difference: 3,334 versus 2,464, which translates to a 35.3% advantage. These results confirm that AMD's multi-threaded performance is the defining strength of this comparison.

Single-core results tell a different story. The Intel Core 9 270H wins Cinebench R15 single-core with 347 points against AMD's 301, a 13.3% margin. In Cinebench R23 single-core, Intel leads by a narrower 2.5% (2,040 versus 1,988). PassMark single-thread also favors Intel, with 3,944 versus 3,867, a 2% edge. While Intel holds the single-thread crown, the margins are small except in the older R15 test.

The integer and floating-point math tests both go to AMD. PassMark integer math shows 121,754 for AMD versus 97,654 for Intel, a 24.7% lead. Floating-point math is closer: 75,153 versus 70,640, a 6.4% margin. Data compression also favors AMD heavily, with 404,918 versus 333,785, a 21.3% difference. Random string sorting goes to AMD by 20.8% (44,552 versus 36,867). Data encryption shows a modest AMD lead of 7.4% (20,802 versus 19,369).

PassMark physics is an Intel win, with 1,966 versus 1,819, a 7.5% margin. Prime number finding goes to AMD by 8.9% (122 versus 112). The overall average benchmark score reflects the same ordering: AMD sits at 46,030 while Intel is at 38,335. The AMD part ranks in the 89th percentile of all CPUs, while Intel sits in the 86th percentile.

Where Each One Wins

The AMD Ryzen AI 9 HX 375 dominates multi-threaded and throughput-oriented tasks. Its 10 benchmark wins span Cinebench R15 and R23 multi-core, data compression, data encryption, extended instructions, prime number finding, floating-point math, integer math, multithread, and random string sorting. The largest wins come in extended instructions (45.8%), Cinebench R15 multi-core (35.3%), and integer math (24.7%). This pattern points to a processor that excels when many threads are active and when the workload can use modern instruction extensions.

The Intel Core 9 270H wins in single-threaded and physics-oriented workloads. Its victories include Cinebench R15 single-core (13.3% ahead), Cinebench R23 single-core (2.5% ahead), PassMark single-thread (2% ahead), and PassMark physics (7.5% ahead). The single-core lead is consistent across all three measured single-thread tests, making Intel the stronger choice for lightly threaded applications. The physics win suggests an advantage in simulation or game-physics calculations that rely on a single primary thread.

The overall scores confirm the split. AMD's average benchmark score of 46,030 exceeds Intel's 38,335 by roughly 20%. The nearest rivals in the database for AMD include the Intel Core Ultra 5 235 at 46,062 (0.1% behind AMD) and the Intel Core i9-13900HX at 46,098 (0.1% behind AMD). For Intel, the nearest rival is the Intel Core Ultra 9 285H at 38,312 (0.1% behind the Core 9 270H). These adjacent scores show that both processors sit near the top of their respective performance tiers.

Architecture Differences

The two processors come from different architectural lineages. AMD uses the Zen 5 architecture with the Strix Point codename, part of the Ryzen AI 300 generation that combines Zen 5 and Zen 5c cores. Intel uses Raptor Lake architecture with the Raptor Lake-H codename, part of the Core 9 generation built on Raptor Lake Refresh. These are fundamentally different designs: AMD's hybrid approach pairs performance and efficiency Zen 5 cores, while Intel's Raptor Lake-H is a more traditional high-power mobile design.

The manufacturing process differs significantly. AMD fabricates on a 4 nm process at TSMC, while Intel uses a 10 nm process at its own foundry. This process gap likely contributes to AMD's efficiency and multi-threaded performance advantages. The die size for AMD is listed at 233 mm², while Intel's die size is not recorded in the database.

Cache topology also differs. Both use 80 KB of L1 per core. The L2 cache is 1 MB per core on AMD versus 2 MB per core on Intel. L3 cache is 16 MB on AMD versus 24 MB shared on Intel. Despite having less total cache, AMD still wins most throughput benchmarks, suggesting that its memory architecture and core efficiency compensate for the smaller cache.

PCIe support differs. AMD offers PCIe Gen 4 with 16 CPU lanes, while Intel offers PCIe Gen 5 with 8 CPU lanes. Both support dual-channel memory. AMD supports DDR5 and LPDDR5X memory with 89.6 GB/s of bandwidth, while Intel supports DDR4 and DDR5 with no bandwidth figure recorded. Neither processor supports ECC memory. Both are mobile-market parts with integrated graphics, but the iGPU differs: AMD uses Radeon 890M while Intel uses Iris Xe Graphics 96EU.

Specification Differences

The core and thread counts differ in an interesting way. The AMD Ryzen AI 9 HX 375 has 12 cores and 24 threads, while the Intel Core 9 270H has 14 cores and 20 threads. Intel has more physical cores but fewer threads, which means the AMD part uses simultaneous multithreading more aggressively. AMD's 24 threads versus Intel's 20 threads helps explain the multi-core benchmark wins.

Clock speeds favor Intel. The AMD base clock is 2.00 GHz with a 5.10 GHz boost. Intel runs at 2.70 GHz base and 5.80 GHz boost. Intel's higher clocks support its single-thread wins, while AMD's thread count and architecture carry the multi-threaded workloads.

Thermal design power differs substantially. AMD is rated at 28 W TDP, while Intel is rated at 45 W TDP. The lower TDP for AMD makes its multi-core dominance more notable, as it achieves higher throughput scores while being rated for less power draw. Neither processor has an unlocked multiplier.

Sockets are incompatible: AMD uses Socket FP8, Intel uses BGA 1744. Release dates differ, with AMD launching on 2024-06-30 and Intel on 2024-12-17. AMD has no recorded launch MSRP, while Intel has a launch MSRP of $697. Manufacturing differs as noted: TSMC 4 nm for AMD, Intel 10 nm for Intel. The part numbers are 100-000001682 for AMD and SRQ6V for Intel.

The Verdict

The recorded data points to the AMD Ryzen AI 9 HX 375 as the stronger overall processor. It wins the majority of benchmarks, holds a 20% lead in average benchmark score (46,030 versus 38,335), and does so with a lower 28 W TDP against Intel's 45 W TDP. The multi-core wins are substantial, with Cinebench R23 showing a 21.2% lead and Cinebench R15 showing a 35.3% lead. The extended instructions win of 45.8% indicates that AMD is particularly strong in modern, instruction-heavy workloads. The 89th percentile ranking versus Intel's 86th percentile confirms the overall standing.

The Intel Core 9 270H is the choice when single-thread performance is the priority. It wins every recorded single-thread test, with the largest margin in Cinebench R15 single-core at 13.3%. Its higher base and boost clocks (2.70 GHz and 5.80 GHz) support this strength. The physics benchmark win (7.5%) also favors Intel for workloads that depend on a single fast thread. However, Intel's 5 wins come with smaller average margins than AMD's 10 wins, and its 45 W TDP is higher while delivering fewer threads.

For users running multi-threaded compilation, data compression, encryption, or floating-point and integer math, the AMD part is clearly ahead. For users running lightly threaded applications where single-core speed is the bottleneck, the Intel part offers a modest edge. The overall database ranking places AMD higher, and its benchmark wins are more numerous and larger in magnitude. The verdict from the data: the AMD Ryzen AI 9 HX 375 is the superior all-around mobile processor, while the Intel Core 9 270H is a specialized option for single-thread-sensitive tasks.
