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

The AMD Ryzen AI 9 HX 375 and the Intel Core i9-14900KS represent two opposite poles of the processor market. The AMD chip is a 28-watt mobile part designed for thin-and-light laptops, while the Intel chip is a 150-watt desktop flagship built for maximum performance. The database shows a complete sweep: the Intel Core i9-14900KS wins all 17 head-to-head benchmark comparisons, with an average benchmark score of 81127 compared to 46030 for the AMD part. This analysis breaks down where each processor holds its ground, the architectural reasons behind the results, and what the recorded data means for potential use cases.

Where Each One Wins

The benchmark results indicate a total victory for the Intel Core i9-14900KS. In every recorded test, from Cinebench to Geekbench to PassMark, the Intel chip posts the higher score. The AMD Ryzen AI 9 HX 375 does not record a single win in the head-to-head comparison. However, the context matters. The AMD processor sits in the 89th percentile of all CPUs, while the Intel chip sits in the 96th percentile. Both are high performers, but the Intel part operates in a different performance class entirely.

The AMD chip's wins, if they can be called that, are in efficiency and platform fit rather than raw speed. The database shows a 28-watt TDP for the AMD part versus 150 watts for the Intel part. The AMD chip uses the AMD Socket FP8, a mobile platform, while the Intel chip uses Intel Socket 1700, a desktop platform. The AMD part is a mobile processor with integrated Radeon 890M graphics, while the Intel part is a desktop processor with UHD Graphics 770. For a laptop builder, the AMD chip is the only option that fits the power and thermal envelope. For a desktop builder chasing maximum performance, the Intel chip is the clear choice.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen AI 9 HX 375 uses the Zen 5 architecture, codenamed Strix Point, built on a 4 nm process by TSMC. The die size is 233 mm². The Intel Core i9-14900KS uses the Raptor Lake architecture, codenamed Raptor Lake-R, built on a 10 nm process by Intel. The die size is 257 mm².

The core configurations differ significantly. The AMD part has 12 cores and 24 threads, with a base clock of 2.00 GHz and a boost clock of 5.10 GHz. The Intel part has 24 cores and 32 threads, with a base clock of 3.20 GHz and a boost clock of 6.20 GHz. The Intel chip's core count is double the AMD chip's core count, and its boost clock is over a gigahertz higher.

Cache layouts also differ. Both parts have 80 KB of L1 cache per core. The AMD part has 1 MB of L2 cache per core and 16 MB of L3 cache. The Intel part has 2 MB of L2 cache per core and 36 MB of shared L3 cache. The Intel chip's larger L2 and L3 caches give it a substantial advantage in workloads that benefit from larger on-chip data storage.

Memory support diverges as well. The AMD part supports DDR5 and LPDDR5X memory over a dual-channel bus, with a memory bandwidth of 89.6 GB/s. The Intel part supports DDR4 and DDR5 memory over a dual-channel bus, with no recorded memory bandwidth figure in the database. The Intel part supports ECC memory, while the AMD part does not. PCIe connectivity differs: the AMD part uses Gen 4 with 16 CPU lanes, while the Intel part uses Gen 5 with 16 CPU lanes.

Head-to-Head Benchmarks

The largest single-core victory for the Intel Core i9-14900KS comes in Cinebench R23 single-core, where it scores 7199 against the AMD's 1988, a delta of -72.4% for the AMD part. That is a massive gap. The Intel chip's boost clock of 6.20 GHz clearly translates into single-thread performance that the AMD's 5.10 GHz boost cannot match.

In multi-core workloads, the Intel chip's advantage is also large but slightly smaller in percentage terms. Cinebench R23 multi-core shows the Intel part at 50995 versus the AMD part at 21812, a delta of -57.2%. This reflects the Intel chip's 24 cores and 32 threads versus the AMD's 12 cores and 24 threads.

Geekbench results follow the same pattern. In Geekbench single-core, the Intel part scores 2692 against the AMD's 2084, a delta of -22.6%. In Geekbench multi-core, the Intel part scores 23931 against the AMD's 13957, a delta of -41.7%. The single-core gap here is smaller than in Cinebench, but the multi-core gap remains substantial.

PassMark tests show consistent Intel dominance. In integer math, the Intel part scores 212644 against the AMD's 121754, a delta of -42.7%. In floating-point math, the Intel part scores 153975 against the AMD's 75153, a delta of -51.2%. In data compression, the Intel part scores 803368 against the AMD's 404918, a delta of -49.6%. In data encryption, the Intel part scores 47717 against the AMD's 20802, a delta of -56.4%. The smallest PassMark gap is in single-thread performance, where the Intel part scores 4815 against the AMD's 3867, a delta of -19.7%.

The physics test shows a delta of -46.2%, with the Intel part at 3381 and the AMD part at 1819. Random string sorting shows a delta of -50.4%, with the Intel part at 89789 and the AMD part at 44552. Find prime numbers shows a delta of -50%, with the Intel part at 244 and the AMD part at 122. Extended instructions show a delta of -35.7%, with the Intel part at 45524 and the AMD part at 29269.

The Verdict

The data points to a clear conclusion for performance-focused builders. The Intel Core i9-14900KS is the superior processor in every benchmark recorded. It wins all 17 head-to-head tests, offers a higher average benchmark score, and sits in a higher percentile of all CPUs. The Intel part's 24 cores, 32 threads, 6.20 GHz boost clock, and 36 MB of L3 cache give it a decisive edge in both single-threaded and multi-threaded workloads.

The AMD Ryzen AI 9 HX 375 serves a different purpose. Its 28-watt TDP, mobile socket, and integrated Radeon 890M graphics make it a laptop processor. The database shows it at the 89th percentile of all CPUs, which is respectable for a mobile part. Its nearest rivals include the Intel Core i9-13900HX, a mobile processor, and the AMD EPYC 4364P, a server chip. The Intel Core i9-14900KS, by contrast, has nearest rivals that are workstation and high-end desktop parts, including the Intel Xeon w5-3535X and the AMD Ryzen 9 8940HX.

For a desktop builder with access to a 150-watt power budget and a Socket 1700 motherboard, the Intel Core i9-14900KS is the obvious choice. For a laptop user who needs a capable processor that fits a mobile power envelope, the AMD Ryzen AI 9 HX 375 is the appropriate part. The two processors do not compete in the same market segment, and the benchmark data confirms that the Intel chip is in a different performance class.
