AMD Ryzen AI 9 HX 375 vs Intel Core Ultra 5 228V Comparison

The AMD Ryzen AI 9 HX 375 and the Intel Core Ultra 5 228V occupy different tiers in the mobile processor market, and the benchmark data reflects a clear split in their design goals. The AMD chip dominates in multi-threaded and compute-heavy tasks, while the Intel part shows a specific strength in one niche workload. The recorded data shows the AMD Ryzen AI 9 HX 375 winning 14 of the 15 shared benchmark comparisons, with the Intel Core Ultra 5 228V taking a single, narrow victory. The average benchmark score for the AMD processor is 46030, placing it at the 89th percentile of all CPUs, while the Intel processor averages 21440, which lands it at the 75th percentile. This positions the AMD part as the higher-performance option overall, though the Intel chip’s much lower 17 W TDP and distinct architecture indicate a different intended use case.

Where Each One Wins

The AMD Ryzen AI 9 HX 375 is the clear winner in almost every workload category measured. Its largest victories come in integer math, where it scores 121754 against the Intel’s 39679, a 206.8% advantage. Data compression also shows a massive gap, with the AMD part scoring 404918 versus 173924, a 132.8% lead. In rendering workloads, the AMD chip delivers 21812 in Cinebench R23 multi-core against 9932 for the Intel, a 119.6% difference. The pattern holds across extended instructions (29269 vs 14801, a 97.8% lead), multithreaded performance (32916 vs 18227, 80.6% ahead), and data encryption (20802 vs 13032, 59.6% ahead). Random string sorting also favors AMD heavily at 44552 versus 21254, a 109.6% margin. Even in floating-point math, where the gap is smaller, AMD still leads with 75153 against 53310, a 41% advantage.

The Intel Core Ultra 5 228V wins only one benchmark: PassMark find prime numbers, where it scores 168 against the AMD’s 122, a 27.4% improvement. This single win indicates a specific strength in a particular mathematical operation, but it does not translate into broader performance superiority. In single-threaded workloads, the two are nearly identical; the AMD chip scores 3867 in PassMark single-thread against the Intel’s 3836, a margin of just 0.8%. The Cinebench R23 single-core test shows a similar but slightly larger gap, with AMD at 1988 versus 1758, a 13.1% lead. For users prioritizing multi-core throughput, rendering, compression, or encryption, the data points decisively to the AMD processor.

Architecture Differences

The two processors use fundamentally different designs. The AMD Ryzen AI 9 HX 375 is built on the Zen 5 architecture with the Strix Point codename, using a 4 nm process from TSMC. It has 12 cores and 24 threads, with a base clock of 2.00 GHz and a boost clock of 5.10 GHz. Its cache layout includes 80 KB of L1 per core, 1 MB of L2 per core, and 16 MB of L3. The die size is 233 mm². The Intel Core Ultra 5 228V uses the Lunar Lake architecture, also fabricated by TSMC but on a 3 nm process. It has 8 cores and 8 threads, with a base clock of 2.10 GHz and a boost clock of 4.50 GHz. Its cache includes 192 KB of L1 per core, 2.5 MB of L2 per core, and 8 MB of shared L3. The Intel part has no die size recorded in the database.

The thread count difference is notable: the AMD processor supports simultaneous multithreading with 24 threads, while the Intel processor runs 8 threads across 8 cores. This explains much of the multi-core performance gap. The AMD chip has a 28 W TDP, while the Intel chip is rated at 17 W. The AMD processor uses the AMD Socket FP8, while the Intel part uses Intel BGA 2833. Memory support also differs, with the AMD chip supporting DDR5 and LPDDR5X at 89.6 GB/s bandwidth, while the Intel chip’s memory support is listed as depending on the motherboard. Both use dual-channel memory buses. The AMD chip supports PCIe Gen 4 with 16 CPU lanes, while the Intel chip supports PCIe Gen 5 with 4 CPU lanes. Integrated graphics differ as well, with the AMD part using the Radeon 890M and the Intel part using the Arc 130V. Both processors are unlocked multipliers false and do not support ECC memory.

Head-to-Head Benchmarks

The head-to-head data shows a consistent pattern of AMD dominance, with the largest margins in compute-intensive workloads. The PassMark integer math test shows the biggest gap, with the AMD chip scoring 121754 against 39679, a 206.8% advantage. This indicates a substantial difference in general-purpose arithmetic performance. Data compression follows at 404918 versus 173924, a 132.8% lead, suggesting the AMD processor handles file compression and decompression tasks much more efficiently. Cinebench R15 multi-core shows 3334 versus 1502.5, a 121.9% lead, and Cinebench R23 multi-core shows 21812 versus 9932, a 119.6% lead, confirming the AMD part’s strength in rendering workloads.

Random string sorting shows a 109.6% lead for AMD, with scores of 44552 versus 21254. Extended instructions show a 97.8% lead, with 29269 versus 14801. The PassMark multithread test shows 32916 versus 18227, an 80.6% lead. Data encryption shows 20802 versus 13032, a 59.6% lead. Floating-point math shows a smaller but still decisive 41% lead, with 75153 versus 53310. The PassMark physics test shows 1819 versus 1538, an 18.3% lead. Cinebench R23 single-core shows 1988 versus 1758, a 13.1% lead, and Cinebench R15 single-core shows 301 versus 267, a 12.7% lead. The PassMark single-thread tests show the closest margins, with 3867 versus 3836, a 0.8% lead for AMD. The only Intel win is the PassMark find prime numbers test, where the Intel chip scores 168 against 122, a 27.4% improvement. This single result shows that the Intel architecture has a specific advantage in prime number calculation, but it is an isolated case in an otherwise one-sided comparison.

The Verdict

The recorded data shows that the AMD Ryzen AI 9 HX 375 is the higher-performance processor in nearly every measured category. Its 12 cores and 24 threads, combined with a 5.10 GHz boost clock, deliver scores that are more than double the Intel part in several benchmarks. The 119.6% lead in Cinebench R23 multi-core and the 206.8% lead in PassMark integer math are decisive indicators for multi-threaded workloads. The AMD chip also holds a smaller but consistent lead in single-threaded tests, with a 13.1% advantage in Cinebench R23 single-core and a 0.8% lead in PassMark single-thread. The 89th percentile ranking for AMD versus the 75th percentile for Intel reinforces this overall performance gap.

The Intel Core Ultra 5 228V offers a different profile, with a lower 17 W TDP compared to the AMD’s 28 W. Its single benchmark win in PassMark find prime numbers, with a 27.4% improvement, does not offset the widespread performance deficits in other tests. The near-identical PassMark single-thread scores, at 3867 versus 3836, show that the Intel part can match the AMD chip in lightly threaded scenarios, but the multi-core results show a wide gap. The Intel processor’s 3 nm process node and 8 MB of shared L3 cache represent a different design approach, but the benchmark results indicate that the AMD processor delivers more performance overall. For workloads that rely on multi-core throughput, rendering, compression, or encryption, the data points to the AMD Ryzen AI 9 HX 375 as the stronger choice. For scenarios where the lower power envelope of the Intel part is the priority, the single-threaded parity suggests it can handle basic tasks, but the overall performance advantage belongs to the AMD processor.
