For a desktop chip, the Ryzen 5 7400's performance profile is respectable, but it is outclassed in every measurable way by the Ryzen AI 9 HX 370.

Architecture Differences

The two processors come from different AMD families and use different architectures. The Ryzen 5 7400 is based on Zen 4 architecture with the codename Raphael, part of the 7000 series. The Ryzen AI 9 HX 370 uses Zen 5 architecture with the codename Strix Point, belonging to the Ryzen AI 300 generation, which combines Zen 5 and Zen 5c cores.

Manufacturing processes differ. The Ryzen 5 7400 is built on a 5 nm node at TSMC, while the Ryzen AI 9 HX 370 uses a 4 nm node at TSMC. The die sizes reflect this difference: the Ryzen 5 7400 has a die size of 71 mm², while the Ryzen AI 9 HX 370 has a die size of 233 mm². The transistor count is 6,570 million for the Ryzen 5 7400; the database does not list a transistor count for the Ryzen AI 9 HX 370.

Cache structures differ per core. The Ryzen 5 7400 has 64 KB of L1 cache per core, while the Ryzen AI 9 HX 370 has 80 KB per core. Both have 1 MB of L2 cache per core. L3 cache is 16 MB shared for the Ryzen 5 7400 and 16 MB for the Ryzen AI 9 HX 370.

The integrated graphics differ. The Ryzen 5 7400 uses Radeon Graphics, while the Ryzen AI 9 HX 370 uses Radeon 890M. The memory support also differs: the Ryzen 5 7400 supports DDR5 only, while the Ryzen AI 9 HX 370 supports both DDR5 and LPDDR5X.

PCIe connectivity differs. The Ryzen 5 7400 supports PCIe Gen 5 with 24 lanes (CPU only), while the Ryzen AI 9 HX 370 supports PCIe Gen 4 with 16 lanes (CPU only).

Specification Differences

The most obvious specification difference is core count: 6 cores and 12 threads for the Ryzen 5 7400 versus 12 cores and 24 threads for the Ryzen AI 9 HX 370. This directly explains much of the multithreaded performance gap.

Clock speeds differ substantially. The Ryzen 5 7400 has a base clock of 3.30 GHz and a boost of 4.30 GHz. The Ryzen AI 9 HX 370 has a lower base of 2.00 GHz but a much higher boost of 5.10 GHz. The higher boost clock helps the HX 370 in single-threaded scenarios.

TDP is a major differentiator. The Ryzen 5 7400 is rated at 65 W, while the Ryzen AI 9 HX 370 is rated at 28 W. The mobile chip delivers more performance at less than half the TDP.

Memory bandwidth differs slightly. The Ryzen 5 7400 has 83.2 GB/s, while the Ryzen AI 9 HX 370 has 89.6 GB/s. Both use dual-channel memory buses.

ECC support is exclusive to the Ryzen 5 7400. The Ryzen AI 9 HX 370 does not support ECC memory.

The multiplier is unlocked on the Ryzen 5 7400, while it is locked on the Ryzen AI 9 HX 370. This matters for overclocking, but the database does not list any overclocking benchmark results.

Release dates differ. The Ryzen 5 7400 was released on 2025-09-15, while the Ryzen AI 9 HX 370 was released on 2024-06-30.

Head-to-Head Benchmarks

The database records 11 head-to-head benchmark comparisons, and the Ryzen AI 9 HX 370 wins all of them. The largest deltas appear in the math-heavy tests.

In floating-point math, the HX 370 scores 76,892 versus 40,784 for the Ryzen 5 7400. That is a -47% delta, meaning the Ryzen 5 7400 is nearly half as fast in this workload. Integer math is similarly lopsided: 122,933 versus 64,733, a -47.3% delta.

Multithreaded performance strongly favors the HX 370. The PassMark multithread score is 35,148 versus 21,712, a -38.2% delta. Physics simulation follows the same pattern: 1,881 versus 1,150, a -38.9% delta.

Data compression shows a wide gap: 445,719 versus 261,749, a -41.3% delta. Data encryption is 22,252 versus 14,865, a -33.2% delta. Extended instructions score 31,653 versus 19,924, a -37.1% delta. Prime number finding is 126 versus 79, a -37.3% delta. Random string sorting is 48,723 versus 31,110, a -36.1% delta.

The closest result is in single-thread performance. Both the passmark_single_thread and passmark_singlethread tests show 3,973 for the HX 370 versus 3,248 for the Ryzen 5 7400, a -18.2% delta. This is still a clear win for the HX 370, but the relative gap is much smaller than in multithreaded tests.

Average benchmark scores reflect the overall picture. The Ryzen 5 7400 has an average benchmark score of 42,055, while the Ryzen AI 9 HX 370 has an average of 37,904. Interestingly, the Ryzen 5 7400 has a higher average score despite losing every head-to-head test. This is because the benchmark sets differ: the Ryzen 5 7400's PassMark scores are weighted differently, and the HX 370's average includes additional tests like Cinebench R15 and R23, Geekbench, and 3DMark that are not present in the Ryzen 5 7400's data. The percentile rankings are close: the Ryzen 5 7400 sits at the 88th percentile of all CPUs, while the HX 370 sits at the 86th percentile.

Nearest rivals provide context. The Ryzen 5 7400's closest competitors include the AMD Ryzen 9 PRO 8945HS (average score 41,963, +0.2% delta), Intel Core i7-14700T (41,914, +0.3%), Intel Core i7-12850HX (41,779, +0.7%), and Intel Core i9-12900K (42,335, -0.7%). The Ryzen AI 9 HX 370's nearest rivals include the Intel Core i9-14901E (37,911, 0% delta), AMD Ryzen 7 9700X (37,943, -0.1%), Intel Core 5 211E (37,829, +0.2%), and AMD Ryzen AI Embedded P132 (37,804, +0.3%).

The Verdict

The data supports a straightforward conclusion. The AMD Ryzen AI 9 HX 370 wins every single head-to-head benchmark comparison against the AMD Ryzen 5 7400. In multithreaded workloads, the margin is consistently around 36-47% in favor of the HX 370. In single-threaded workloads, the HX 370 leads by 18.2%.

The Ryzen AI 9 HX 370 achieves this with 12 cores versus 6, a higher boost clock (5.10 GHz versus 4.30 GHz), and a lower TDP (28 W versus 65 W). It uses a newer 4 nm process versus 5 nm, newer Zen 5 architecture versus Zen 4, and supports faster memory bandwidth (89.6 GB/s versus 83.2 GB/s). The only areas where the Ryzen 5 7400 holds an advantage are ECC memory support, an unlocked multiplier, PCIe Gen 5 with 24 lanes versus Gen 4 with 16 lanes, and a higher average benchmark score (42,055 versus 37,904) due to differing test sets.

For desktop builders who need ECC memory or PCIe Gen 5, the Ryzen 5 7400 is the only option of the two. For anyone prioritizing raw performance per watt, multithreaded throughput, or single-thread speed, the Ryzen AI 9 HX 370 is the clear choice based on recorded measurements. The mobile chip delivers more performance in every direct comparison while consuming less power.

The Ryzen 5 7400 remains a capable desktop processor, but the head-to-head data does not show a single workload where it outperforms the Ryzen AI 9 HX 370. The verdict from the database is unambiguous: the Ryzen AI 9 HX 370 is the faster processor in all tested scenarios.
