AMD Ryzen AI 9 PRO 465 vs Intel Core Ultra 5 338H Comparison

The Verdict

The recorded data splits these two mobile processors into distinct roles. The AMD Ryzen AI 9 PRO 465 holds a decisive edge in multithreaded throughput and integer-heavy workloads, while the Intel Core Ultra 5 338H counters with superior floating-point performance and a significant advantage in prime-number calculation. The AMD part wins 5 of the 11 head-to-head tests, the Intel part wins 6, but the magnitude of the wins differs sharply. AMD's largest victory is a 65% lead in integer math; Intel's largest is a 58.6% lead in prime-number finding. For users prioritizing parallel integer workloads, data compression, or random string sorting, the AMD processor is the stronger choice. For users needing floating-point math or physics simulation, the Intel processor delivers better results. The AMD chip also occupies a higher overall position in the database, ranking in the 93rd percentile versus the Intel part's 84th percentile.

Architecture Differences

The two processors use fundamentally different design approaches. The AMD Ryzen AI 9 PRO 465 is built on a 4 nm TSMC process using the Zen 5 architecture with the Gorgon Point codename. It packs 10 cores and 20 threads, with a base clock of 2.00 GHz and a boost clock of 5.00 GHz. Its thermal design power is 28 W. The Intel Core Ultra 5 338H uses a 3 nm Intel process with the Panther Lake architecture and Panther Lake codename. It has 12 cores but only 12 threads, meaning no simultaneous multithreading. Its base clock is 1.90 GHz with a boost clock of 4.70 GHz, and its thermal design power is 25 W.

Cache configurations differ substantially. The AMD part provides 80 KB of L1 per core, 1 MB of L2 per core, and 16 MB of L3 cache. The Intel part has 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3 cache. The Intel chip therefore has more cache at every level per core, though the AMD chip's L3 is not marked as shared in the same way.

Memory support also diverges. The AMD processor supports both DDR5 and LPDDR5X memory over a dual-channel bus, with a recorded memory bandwidth of 89.6 GB/s. The Intel processor supports only LPDDR5X memory, also dual-channel, but with a higher recorded bandwidth of 136.5 GB/s. PCIe connectivity differs as well: the AMD part uses Gen 4 with 16 CPU lanes, while the Intel part uses Gen 5 with 4 CPU lanes. Integrated graphics differ: the AMD chip uses the Radeon 890M, the Intel chip uses the Arc B370. Both processors are mobile parts, both are active in production, and both launched on the same date. Neither has an unlocked multiplier. The AMD chip uses AMD Socket FP8, while the Intel chip uses Intel BGA 2540.

Head-to-Head Benchmarks

The largest single delta in the comparison is in PassMark integer math, where the AMD Ryzen AI 9 PRO 465 scores 107,173 against the Intel Core Ultra 5 338H's 64,934, a 65% advantage. This is the clearest demonstration of the AMD part's strength in general integer computation. Data compression follows a similar pattern: AMD scores 385,174 versus Intel's 276,539, a 39.3% lead. Random string sorting also favors AMD, with 40,860 versus 34,082, a 19.9% margin. Extended instructions go to AMD at 26,441 versus 23,906, a 10.6% advantage. The multithread score, a broad measure of parallel capability, favors AMD at 31,485 versus 28,717, a 9.6% lead.

The Intel processor responds with several notable wins. Prime-number finding shows Intel at 304 versus AMD's 126, a 58.6% lead. Floating-point math goes to Intel at 84,067 versus 66,824, a 20.5% advantage. Physics simulation favors Intel at 2,697 versus 1,747, a 35.2% margin. Data encryption goes to Intel at 21,367 versus 19,308, a 9.6% lead. The single-thread scores are nearly identical: Intel records 4,180 versus AMD's 4,168, a 0.3% difference. The same delta appears in the duplicate single-thread entry in the database. The overall benchmark averages in the database reflect a large gap: the AMD part has an average benchmark score of 62,498, while the Intel part sits at 33,989. This difference is explained by the fact that the AMD chip's nearest rivals are high-end desktop parts like the Intel Core i9-13900KF, which it leads by 1.1%, while the Intel chip's nearest rivals are mid-range mobile and server parts like the Intel Core Ultra 7 165H, which it trails by 0.3%.

The AMD processor's nearest rival data places it just below the Intel Core Ultra 7 255HX by 0.4%, just below the AMD Ryzen AI Embedded P185 by 0.5%, and just below the Intel Core i7-13790F by 0.9%. It sits above the Intel Core i9-13900KF by 1.1%. The Intel Core Ultra 5 338H, by contrast, sits 0.3% below the Intel Core Ultra 7 165H, 0.3% above the Intel Core i7-12800HX, 0.4% above the Intel Xeon 6353P, and 0.7% below the AMD EPYC 4244P. The AMD chip's percentile ranking of 93 versus the Intel chip's 84 confirms that the AMD part places higher in the overall database distribution.

Where Each One Wins

The AMD Ryzen AI 9 PRO 465 wins in workloads that stress parallel integer execution and data manipulation. Its 65% lead in integer math is the standout result, and its 39.3% lead in data compression points toward archive handling, database operations, and similar tasks. The 19.9% lead in random string sorting reinforces the pattern: this processor handles sorting and text-processing pipelines more efficiently. The 10.6% lead in extended instructions suggests better support for specialized instruction sets. The 9.6% lead in multithread score indicates that the 20-thread configuration provides a real advantage in broadly parallel workloads. The AMD chip also holds the higher average benchmark score and the higher percentile ranking, so in aggregate it is the faster processor in the database's overall measurement.

The Intel Core Ultra 5 338H wins in workloads that favor floating-point throughput and certain algorithmic patterns. Its 58.6% lead in prime-number finding is the largest single margin in either direction, and its 35.2% lead in physics simulation makes it the better choice for physics-based computation. The 20.5% lead in floating-point math covers scientific and engineering workloads that rely on non-integer arithmetic. The 9.6% lead in data encryption is a smaller but still meaningful advantage for security-related tasks. The single-thread result, though only 0.3% in Intel's favor, means the two chips are interchangeable for lightly threaded applications. The Intel part also offers higher memory bandwidth and a newer 3 nm process node, which may matter in memory-bound scenarios despite the AMD part's overall benchmark advantage.
