AMD Ryzen AI 9 HX 375 vs Intel Core i7-14700HX Comparison

The AMD Ryzen AI 9 HX 375 and Intel Core i7-14700HX are both high-end mobile processors, and the benchmark data shows a clear split in their strengths. The Intel part wins a decisive majority of the head-to-head tests, while the AMD chip carves out a narrow but significant niche in specific workloads. Both processors land in the 89th percentile of all CPUs, and their average benchmark scores are nearly identical — the AMD Ryzen AI 9 HX 375 averages 46030, while the Intel Core i7-14700HX averages 45953. That overall parity masks a very one-sided set of individual test results.

Head-to-Head Benchmarks

The Intel Core i7-14700HX dominates the multi-threaded and compute-heavy workloads. In Cinebench R23 multi-core, Intel scores 24595 against AMD’s 21812, a 11.3% advantage. The gap is even wider in Cinebench R15 multi-core, where Intel leads 3812 to 3334, a 12.5% margin. Geekbench multi-core also favors Intel, with a score of 14390 versus 13957, a 3% lead. This pattern holds across the PassMark suite, where Intel wins 13 of the 15 listed tests.

The largest Intel victories come in the most specialized tasks. In PassMark find prime numbers, Intel scores 165 against AMD’s 122, a 26.1% advantage — the biggest delta in the entire comparison. PassMark data encryption shows Intel at 26092 versus AMD’s 20802, a 20.3% lead. Floating point math is also strongly Intel-favored: 93836 against 75153, a 19.9% margin, and PassMark physics follows with 2252 versus 1819, a 19.2% gap. These are not marginal wins; the Intel part is delivering substantially higher throughput in math, encryption, and physics simulations.

The AMD Ryzen AI 9 HX 375 wins only two of the 17 head-to-head tests, but both are meaningful. In Cinebench R15 single-core, AMD scores 301 against Intel’s 296, a 1.7% lead. The more significant win is in PassMark extended instructions, where AMD scores 29269 against Intel’s 25718, a 13.8% advantage. That is the only test outside of the single-core Cinebench R15 where AMD outperforms, and it suggests the Zen 5 architecture has a distinct edge in certain instruction-level workloads.

The single-core picture is closer than the multi-core results. In Geekbench single-core, Intel leads 2116 to 2084, a 1.5% margin. Cinebench R23 single-core shows Intel ahead at 2103 versus 1988, a 5.5% gap. PassMark single-thread also goes to Intel, 3947 to 3867, a 2% difference. AMD’s lone single-core win in Cinebench R15 is notable, but the broader data indicates Intel holds a slight but consistent single-thread advantage.

The remaining PassMark tests all favor Intel by single-digit margins. Integer math: 131296 to 121754, a 7.3% lead. Data compression: 438539 to 404918, a 7.7% margin. Random string sorting: 48544 to 44552, an 8.2% gap. PassMark multithread: 36566 to 32916, a 10% difference. These results reinforce the narrative that Intel’s higher core count translates into broad multi-threaded superiority, while AMD’s wins are concentrated in very specific instruction paths.

The Verdict

The data is unambiguous: the Intel Core i7-14700HX is the faster processor for the vast majority of workloads. It wins 15 of 17 head-to-head benchmarks, and its victories span single-core, multi-core, and specialized compute tasks. The only areas where the AMD Ryzen AI 9 HX 375 takes the lead are Cinebench R15 single-core and PassMark extended instructions. For users who prioritize raw throughput in rendering, encryption, physics, or general number crunching, the Intel part is the clear choice based on the scores.

That said, the AMD chip is not a poor performer. Its average benchmark score of 46030 is actually higher than Intel’s 45953, and both sit at the 89th percentile. The AMD part also matches or beats several other rivals, including the Intel Core Ultra 5 235, which scores 46062 with a 0.1% delta, and the AMD EPYC 4364P at 45970. The Ryzen AI 9 HX 375 holds its own in the broader market, but in a direct comparison with the Core i7-14700HX, the Intel part wins decisively on test count and on most large-margin victories.

The verdict depends on the workload. For general-purpose computing, multi-threaded rendering, and most productivity tasks, the Intel Core i7-14700HX is the stronger option. For users who specifically need extended instruction set performance — a niche but real requirement — the AMD Ryzen AI 9 HX 375 offers a 13.8% advantage that Intel cannot match. The data does not support a recommendation for AMD for most buyers, but it does carve out a legitimate use case for the Strix Point chip.

Where Each One Wins

The Intel Core i7-14700HX wins in every major multi-threaded benchmark category. Cinebench R23 multi-core, Cinebench R15 multi-core, and Geekbench multi-core all go to Intel with margins ranging from 3% to 12.5%. In the PassMark suite, Intel wins data compression, data encryption, find prime numbers, floating point math, integer math, multithread, physics, and random string sorting. The margins are largest in encryption (20.3%), floating point (19.9%), and physics (19.2%), which points to strong performance in scientific computing, financial modeling, and simulation workloads.

The AMD Ryzen AI 9 HX 375 wins in PassMark extended instructions, with a 13.8% lead over Intel. This is a specific but important category that covers advanced instruction sets like AVX-512 and similar extensions. For workloads that rely heavily on these instructions — certain AI inference tasks, cryptography, or specialized media processing — the AMD part has a measurable advantage. The AMD chip also edges out Intel in Cinebench R15 single-core by 1.7%, though this is a minor win given Intel’s superiority in the other single-core tests.

In terms of efficiency, the AMD part has a much lower TDP at 28 watts versus Intel’s 55 watts. This is not a benchmark score, but it is a significant architectural difference that could influence thermal and battery behavior in a laptop. The data does not include battery life or thermal tests, but the TDP figures suggest the AMD chip may run cooler and consume less power under load, which could be a deciding factor for mobile users.

Architecture Differences

The Intel Core i7-14700HX is built on Intel’s 10 nm process with a die size of 257 mm², while the AMD Ryzen AI 9 HX 375 uses TSMC’s 4 nm node with a smaller 233 mm² die. The Intel part is based on the Raptor Lake architecture, specifically the Raptor Lake-HX refresh, and belongs to the Core 14th Gen series. The AMD chip uses the Zen 5 architecture, codenamed Strix Point, and is part of the Ryzen AI 300 generation, which combines Zen 5 and Zen 5c cores.

The cache configurations differ significantly. The Intel Core i7-14700HX offers 2 MB of L2 cache per core and 33 MB of shared L3 cache. The AMD Ryzen AI 9 HX 375 has 1 MB of L2 per core and 16 MB of L3 cache. Both have 80 KB of L1 cache per core. The Intel part’s larger L3 cache and double L2 per core likely contribute to its multi-threaded performance advantage.

Memory support also differs. The Intel chip supports both DDR4 and DDR5, while the AMD chip supports DDR5 and LPDDR5X. The AMD part has a memory bandwidth of 89.6 GB/s, while the Intel part’s memory bandwidth is not listed in the data. Intel supports ECC memory, while AMD does not. The AMD chip uses a dual-channel memory bus, as does the Intel part.

PCIe connectivity is a notable difference. The Intel Core i7-14700HX supports PCIe Gen 5 with 16 lanes, while the AMD Ryzen AI 9 HX 375 is limited to PCIe Gen 4 with 16 lanes. This could affect future expansion options, though the data does not include any benchmarks that directly test PCIe bandwidth.

The integrated graphics differ as well. AMD uses the Radeon 890M, while Intel uses UHD Graphics 770. The data does not include iGPU benchmarks, so no performance comparison is possible. The Intel part has an unlocked multiplier, while the AMD chip does not, which may matter for overclocking in supported systems. The Intel chip has a base clock of 2.10 GHz and a boost clock of 5.50 GHz, while the AMD chip runs at 2.00 GHz base and 5.10 GHz boost. The Intel part has a higher TDP of 55 watts, compared to AMD’s 28 watts, which reflects the Intel chip’s higher power draw and potentially higher sustained performance.
