AMD Ryzen AI 9 HX 370 vs Intel Core i5-14400 Comparison

The Verdict

The AMD Ryzen AI 9 HX 370 is the dominant performer in this comparison. The recorded data shows it wins 16 of the 17 head-to-head benchmark comparisons, with the Intel Core i5-14400 taking a single victory. The average benchmark score for the AMD part sits at 37904, placing it in the 86th percentile of all CPUs in the database. The Intel chip's average score is 32115, which puts it in the 82nd percentile. The gap in average scores is roughly 18%, a meaningful margin for most workloads.

The AMD Ryzen AI 9 HX 370 is the pick for users who prioritize multi-threaded throughput, content creation, and data-heavy tasks. Its 12 cores and 24 threads give it a structural advantage in parallel workloads, and the benchmark wins reflect that. The Intel Core i5-14400, with its higher single-core Cinebench R23 score, serves a narrower role. That single win matters for specific single-threaded applications, but the AMD chip still wins the other single-thread tests in the head-to-head set.

For a desktop builder looking at the Intel Socket 1700 platform, the i5-14400 has its place. It is the only one of the two with ECC memory support, which can matter for entry-level workstation builds. However, the data consistently favors the AMD mobile processor across nearly every measured category. The Ryzen AI 9 HX 370 is a mobile part on AMD Socket FP8, so it belongs in laptops rather than a desktop chassis. That distinction is critical: the Intel chip is a desktop processor, while the AMD chip is designed for mobile systems.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI 9 HX 370 uses the Zen 5 architecture under the Strix Point codename, built on a 4 nm process at TSMC. Its die size is 233 mm². The Intel Core i5-14400 uses the Raptor Lake architecture under the Raptor Lake-R codename, built on a 10 nm process at Intel's own foundry, with a die size of 215 mm².

The core configurations diverge sharply. AMD fields 12 cores and 24 threads, while Intel fields 10 cores and 16 threads. The AMD generation label is "Ryzen AI 300 (Zen 5 / Zen 5c)", indicating a hybrid core arrangement within the Zen 5 family. The Intel generation label is "Core i5 (Raptor Lake Refresh)", a refresh of the Raptor Lake design. Process node differences are significant: 4 nm versus 10 nm, which contributes to the AMD chip's 28 W TDP compared to Intel's 65 W TDP.

Cache structures also differ. Both use 80 KB of L1 per core. AMD uses 1 MB of L2 per core, while Intel uses 1.25 MB per core. The L3 cache is 16 MB on AMD and 20 MB shared on Intel. Memory support diverges: AMD supports DDR5 and LPDDR5X, while Intel supports DDR4 and DDR5. AMD's memory bandwidth is recorded at 89.6 GB/s, with no bandwidth figure listed for Intel. ECC memory is available on Intel but not on AMD. PCIe support differs as well: AMD provides Gen 4 with 16 lanes, while Intel provides Gen 5 with 16 lanes.

The integrated graphics are another major split. AMD uses the Radeon 890M, while Intel uses UHD Graphics 730. The AMD part is classified as a mobile segment product, released on 2024-06-30. Intel is a desktop segment product, released on 2024-01-07. The Intel chip carries a launch MSRP of $221; no launch MSRP is recorded for the AMD chip.

Head-to-Head Benchmarks

The head-to-head comparison is lopsided. The AMD Ryzen AI 9 HX 370 wins 16 benchmarks, while Intel wins a single one.

The largest AMD victory comes in Cinebench R15 multi-core, where the AMD chip scores 3409.5 against Intel's 2148, a 58.7% advantage. PassMark extended instructions shows a 59.7% delta in AMD's favor, with scores of 31653 versus 19816. PassMark find prime numbers goes to AMD 126 to 80, a 57.5% lead. GeekBench multi-core shows AMD at 15242 versus Intel's 9807, a 55.4% gap. PassMark random string sorting is 48723 to 32346, a 50.6% delta. PassMark integer math lands at 122933 versus 82017, a 49.9% advantage. PassMark data compression shows 445719 versus 314995, a 41.5% lead. PassMark multi-thread is 35148 versus 25080, a 40.1% delta.

The AMD single-thread advantages are smaller but consistent. PassMark single-thread has AMD at 3973 versus 3741, a 6.2% lead. Cinebench R15 single-core is close, with AMD at 306.5 versus 303, just a 1.2% edge. GeekBench single-core shows a larger 26.4% delta, with AMD at 2407 versus 1905. PassMark physics goes to AMD 1881 to 1396, a 34.7% lead. PassMark floating point math is 76892 versus 61549, a 24.9% gap. PassMark data encryption has AMD at 22252 versus 16731, a 33% delta.

The single Intel win is Cinebench R23 single-core, where the i5-14400 scores 3009 against AMD's 2018, a 32.9% margin in Intel's favor. That is a notable outlier, as the other single-thread tests do not show the same pattern.

Cinebench R23 multi-core is nearly a tie. AMD scores 21761, Intel scores 21315, a 2.1% delta. Despite the massive core count difference, this workload brings them close together.

Where Each One Wins

The AMD Ryzen AI 9 HX 370 dominates in multi-threaded and data-intensive workloads. Cinebench R15 multi-core, GeekBench multi-core, PassMark multi-thread, integer math, floating point math, data compression, data encryption, extended instructions, prime number finding, random string sorting, and physics all go to AMD with double-digit margins in most cases. Users running parallel compilation, video rendering, database operations, or scientific calculations would see the AMD chip pull ahead substantially based on the recorded deltas.

The AMD chip also wins the majority of single-thread tests. PassMark single-thread, GeekBench single-core, and Cinebench R15 single-core all show AMD ahead, though the margins vary. The Cinebench R15 single-core margin is razor-thin at 1.2%, while GeekBench single-core shows a robust 26.4% lead.

The Intel Core i5-14400 has one clear win: Cinebench R23 single-core. The 3009 score versus 2018 is a large margin, and it suggests that certain single-threaded workloads optimized for that specific benchmark would favor Intel. The i5-14400 also holds advantages in platform features. ECC memory support is exclusive to Intel, and PCIe Gen 5 with 16 lanes is available on the Intel socket. DDR4 memory support gives Intel users an upgrade path from older systems without replacing memory.

The Intel chip is a desktop part on Socket 1700, so it fits into existing desktop motherboards. The AMD chip is a mobile part on Socket FP8, which means it is found in laptops. That form factor difference is the deciding factor for many buyers: the AMD chip offers superior performance per the benchmark data, but only in a mobile package. The Intel chip delivers a narrower but still competitive performance profile in a desktop context, with the added benefit of ECC support.

For users who need the fastest recorded multi-thread performance in the database comparison, the AMD Ryzen AI 9 HX 370 is the clear data-driven choice. For users building a desktop system with ECC memory requirements or a preference for the Intel Socket 1700 platform, the i5-14400 offers a single-thread performance edge in Cinebench R23 and platform features the AMD chip lacks.
