AMD Ryzen AI 9 HX 375 vs Intel Core i9-14900F Comparison

The Verdict

The data is unambiguous: the Intel Core i9-14900F dominates the AMD Ryzen AI 9 HX 375 across every recorded benchmark. The head-to-head table shows 17 wins for Intel and zero for AMD, with the average benchmark score for the Intel part at 60008 compared to 46030 for the AMD chip. The Intel processor also holds a higher percentile rank, sitting at 92 versus 89 for the AMD part.

The Intel Core i9-14900F is the clear choice for anyone prioritizing raw compute performance, especially in multi-threaded workloads where its 24 cores and 32 threads provide a decisive structural advantage. The AMD Ryzen AI 9 HX 375, with 12 cores and 24 threads, cannot match that core count, and the benchmark data confirms this gap consistently. The AMD part is a mobile processor with a 28 W TDP, while the Intel part is a desktop processor with a 65 W TDP, so the comparison pits a low-power mobile chip against a full desktop part.

For desktop users building a high-performance workstation or gaming rig, the Intel Core i9-14900F is the only reasonable selection based on this data. For a thin-and-light laptop where power draw is a primary constraint, the AMD Ryzen AI 9 HX 375 is the part that exists in that form factor, but the recorded performance figures show it is not competitive with the Intel desktop chip in any measured category.

Where Each One Wins

The Intel Core i9-14900F wins every single benchmark in the database. The largest margins appear in single-core tests, where the Intel part shows a 64.4% advantage in Cinebench R23 single-core, and in multi-threaded rendering, where it posts a 44.9% lead in Cinebench R23 multi-core. The Intel processor also leads by 40% in PassMark data encryption and by 41.6% in Prime number generation, indicating strong performance in both cryptographic and integer-heavy tasks.

The AMD Ryzen AI 9 HX 375 has no recorded wins. Its closest margin to the Intel part is in PassMark extended instructions, where it trails by only 5.8%, and in PassMark single-thread, where the gap narrows to 14.2%. These smaller deltas suggest that the AMD architecture is relatively more competitive in instruction-set-specific workloads and in lightly threaded tasks, but it still loses those tests outright.

The data also shows that the AMD part has a much lower TDP at 28 W versus 65 W for Intel, which positions the AMD chip as the more efficient option for battery-powered devices. However, the benchmark results indicate that this efficiency comes at a substantial performance cost across all 17 recorded tests.

Architecture Differences

The AMD Ryzen AI 9 HX 375 uses the Zen 5 architecture with the Strix Point codename, part of the Ryzen AI 300 generation that mixes Zen 5 and Zen 5c cores. It is built on a 4 nm process at TSMC with a die size of 233 mm². The chip has 12 cores and 24 threads, with a base clock of 2.00 GHz and a boost clock of 5.10 GHz. Its cache hierarchy includes 80 KB of L1 per core, 1 MB of L2 per core, and 16 MB of L3 cache. The memory interface supports DDR5 and LPDDR5X over a dual-channel bus with a recorded bandwidth of 89.6 GB/s. It uses the AMD Socket FP8 and includes Radeon 890M integrated graphics. The part does not support ECC memory and uses PCIe Gen 4 with 16 lanes.

The Intel Core i9-14900F uses the Raptor Lake architecture with the Raptor Lake-R codename, part of the Core 14th Gen series. It is built on a 10 nm process at Intel with a die size of 257 mm². The chip has 24 cores and 32 threads, with a base clock of 2.00 GHz and a boost clock of 5.80 GHz. Its cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and a larger 36 MB shared L3 cache. The memory interface supports DDR4 and DDR5 over a dual-channel bus, with no bandwidth figure recorded. It uses the Intel Socket 1700 and has no integrated graphics. The part supports ECC memory and uses PCIe Gen 5 with 16 lanes.

The most significant architectural differences are the core counts, the process nodes, and the cache sizes. Intel has twice the cores and 8 more threads, a larger L2 per core, and more than double the L3 cache. AMD has a smaller process node and a smaller die, plus an integrated GPU that Intel lacks. The Intel part also has a higher boost clock by 0.70 GHz.

Head-to-Head Benchmarks

The largest single margin in the entire comparison is in Cinebench R23 single-core. The Intel Core i9-14900F scores 5583, while the AMD Ryzen AI 9 HX 375 scores 1988, a delta of 64.4%. This is a massive gap for a single-threaded test and indicates that the Intel architecture has a substantial per-core performance advantage, likely driven by its higher boost clock and larger cache.

In Cinebench R23 multi-core, the Intel part scores 39551 versus 21812 for AMD, a 44.9% lead. The Intel part also wins Cinebench R15 multi-core by 16.4% with scores of 3986 versus 3334. These rendering workloads show that Intel's additional cores translate directly into throughput gains.

The Geekbench results show a similar pattern. Intel leads multi-core by 30.2% with 20008 versus 13957, and single-core by 18.9% with 2570 versus 2084. The multi-core gap is larger than the single-core gap, consistent with the core count difference.

The PassMark suite reveals consistent Intel advantages across varied workloads. Data compression shows Intel at 564207 versus 404918, a 28.2% lead. Data encryption shows Intel at 34644 versus 20802, a 40% lead. Floating point math shows Intel at 119550 versus 75153, a 37.1% lead. Integer math shows Intel at 177066 versus 121754, a 31.2% lead.

The closest benchmark in the entire set is PassMark extended instructions, where Intel scores 31084 versus 29269 for AMD, a modest 5.8% lead. This suggests that the AMD Zen 5 architecture handles extended instruction sets relatively well, but it still loses this test.

The PassMark single-thread test shows Intel at 4506 versus 3867, a 14.2% lead. This is the second-smallest margin after extended instructions, reinforcing that the AMD part is less disadvantaged in lightly threaded tasks than in heavily parallel workloads. However, the overall pattern is uniform: Intel wins all 17 head-to-head benchmarks, with no exceptions.
