Head-to-Head Benchmarks

The Ryzen AI 9 HX 375 wins all 15 head-to-head benchmark comparisons. The largest single margin appears in Cinebench R23 multi-core, where the Ryzen AI 9 HX 375 scores 21812 against the Ryzen 5 240’s 13013, a delta of -40.3%. That is a massive multi-threaded advantage, driven by double the cores and threads. Cinebench R15 multi-core shows a similar story: 3334 versus 2078, a -37.7% gap. In PassMark physics, the Ryzen AI 9 HX 375 scores 1819 against 1060, a -41.7% delta, which reflects its stronger multi-core throughput in simulation-style workloads.

The single-core gap is much smaller, but still favors the Ryzen AI 9 HX 375. In Cinebench R23 single-core, the Ryzen AI 9 HX 375 scores 1988 versus 1742, a -12.4% delta. Cinebench R15 single-core shows 301 versus 270, a -10.3% gap. PassMark single-thread scores are closer still: 3867 versus 3675, a -5% delta. This pattern indicates that the Ryzen AI 9 HX 375’s Zen 5 cores deliver better per-thread performance, but the architectural advantage is less dramatic than the core-count advantage.

In encryption and compression workloads, the Ryzen AI 9 HX 375 leads by notable margins. PassMark data compression shows 404918 versus 267963, a -33.8% delta. PassMark data encryption shows 20802 versus 15849, a -23.8% delta. These workloads scale with both core count and instruction efficiency, so the Zen 5 part’s lead is expected.

Where Each One Wins

The Ryzen AI 9 HX 375 wins every benchmark category in the recorded data. For heavily multi-threaded workloads, such as Cinebench R23 multi-core and PassMark multithread, the advantage is decisive. The 12-core, 24-thread configuration with Zen 5 cores provides a 40.3% lead in Cinebench R23 multi-core and a 31.2% lead in PassMark multithread. For physics simulation, the Ryzen AI 9 HX 375 scores 1819 versus 1060, a 41.7% lead, making it the stronger choice for CPU-bound simulation tasks. For integer math, it scores 121754 versus 73189, a 39.9% lead. For floating point math, it scores 75153 versus 45301, a 39.7% lead. For prime number calculations, the Ryzen AI 9 HX 375 scores 122 versus 70, a 42.6% lead.

The Ryzen 5 240 has no benchmark wins. Its higher base clock of 4.30 GHz does not translate into a single-thread victory. Its lower TDP of 45 versus 28 does not give it an efficiency advantage in the recorded data. The closest margin for the Ryzen 5 240 is in PassMark single-thread, where it trails by only 5%. That is the only category where the Ryzen 5 240 comes within single digits of the Ryzen AI 9 HX 375. In every other test, the gap is 10% or larger.

The Ryzen 5 240 does have some distinguishing features that may matter for specific system designs. It offers more PCIe lanes at 20 versus 16, which could support more expansion devices. It also has a smaller die size at 178 mm² versus 233 mm², which may influence manufacturing costs but is not reflected in the benchmark scores. Neither chip has an unlocked multiplier, and both are mobile parts.

The Verdict

The recorded data leaves no ambiguity about the performance hierarchy. The AMD Ryzen AI 9 HX 375 is the faster processor in every measured workload, with a lead that ranges from 5% in single-thread tests to over 40% in multi-threaded tests. Its 89th percentile ranking versus the Ryzen 5 240’s 84th percentile reflects this consistent advantage. The Ryzen AI 9 HX 375 also accomplishes this with a lower TDP of 28, compared to the Ryzen 5 240’s 45, which suggests better performance per watt in the database’s measurements.

The Ryzen 5 240 is not a weak processor in absolute terms. Its average benchmark score of 33542 places it near competitors like the Intel Core Ultra 7 255H at 33537 and the AMD Ryzen 7 8840HS at 33667. The Ryzen AI 9 HX 375, however, sits in a different class. Its average score of 46030 is close to the Intel Core i9-13900HX at 46098 and the Intel Core Ultra 5 235 at 46062. That puts the Ryzen AI 9 HX 375 in the company of high-end laptop processors, while the Ryzen 5 240 competes with mid-range parts.

For a system where CPU performance is the priority, the Ryzen AI 9 HX 375 is the clear choice. It delivers roughly 60% higher multi-core scores in Cinebench R23, nearly 40% higher integer math scores, and over 40% higher prime number processing. The Ryzen 5 240 makes sense only in a context where its features, such as the higher PCIe lane count of 20, are more important than raw compute. The benchmark data shows no workload category where the Ryzen 5 240 outperforms the Ryzen AI 9 HX 375.
