Across 15 head-to-head benchmark comparisons, the Intel processor wins 11 and the AMD processor wins 4. Both sit at the 87th percentile of all CPUs in the database, with the Intel part averaging 40313 points and the AMD part averaging 39485 points.

The Verdict

The benchmark data favors the Intel Core i9-13905H for compute-heavy workloads. It wins Cinebench R15 multi-core by 5.3%, R23 multi-core by 9.4%, and Passmark multithread by 13%. Its largest margins come in Passmark find prime numbers (37.1% ahead), floating point math (34.9% ahead), and physics (30.2% ahead). The AMD Ryzen AI 7 450 takes the single-thread crown, winning Passmark single-thread by 5.1% and Cinebench R23 single-core by 0.9%, plus extended instructions by 4.9%.

The Intel part's average benchmark score of 40313 places it alongside the Xeon 6369P (40327, essentially tied) and the Ryzen 9 270 (40246, 0.2% behind), while the Xeon 6507P (40426) and Ryzen 9 7940H (40431) sit 0.3% ahead. The AMD part's 39485 average sits near the Ryzen 7 PRO 8840HS (39603, 0.3% ahead) and the Ryzen 7 9800X3D (39768, 0.7% ahead), with the Ryzen 7 PRO 8845HS (39325) and EPYC 4245P (39215) trailing by 0.4% and 0.7% respectively. Both processors are competitive within their respective peer groups.

Who should pick which? Users running rendering, physics, encryption, or heavy multi-threaded workloads should choose the Intel Core i9-13905H. Users who want stronger single-thread performance, extended instruction throughput, ECC memory support, and a lower 28 W TDP should choose the AMD Ryzen AI 7 450. The Intel part's 45 W TDP and 14-core configuration make it the higher-power option, while the AMD part's 4 nm process and 8-core design deliver a lower thermal envelope.

Architecture Differences

The two processors diverge at the silicon level. The Intel Core i9-13905H uses Raptor Lake architecture (Raptor Lake-H codename) on Intel's 10 nm process, with a die size of 257 mm². The AMD Ryzen AI 7 450 uses Zen 5 architecture (Gorgon Point codename) on TSMC's 4 nm process, with a die size of 195 mm². The AMD part is the newer design, with a release date of 2026-01-04 versus 2023-01-03 for the Intel part.

Core configuration differs substantially. The Intel part has 14 cores and 20 threads, while the AMD part has 8 cores and 16 threads. Both use 80 KB of L1 cache per core, but the Intel part has 2 MB of L2 per core versus 1 MB on the AMD part, and 24 MB of shared L3 versus 8 MB on the AMD part. The larger cache hierarchy on the Intel side likely contributes to its multi-threaded advantages.

Memory support also differs. The Intel part supports DDR4 and DDR5 in a dual-channel configuration, while the AMD part supports DDR5 and LPDDR5X with a memory bandwidth of 89.6 GB/s. The AMD part supports ECC memory; the Intel part does not. PCIe connectivity differs: the Intel part offers Gen 5 with 8 CPU lanes, while the AMD part offers Gen 4 with 16 CPU lanes. Integrated graphics are the Iris Xe Graphics 96EU on the Intel side and the Radeon 860M on the AMD side. Both are mobile parts with locked multipliers, and both are in active production.

Head-to-Head Benchmarks

Of the 15 head-to-head comparisons, the Intel Core i9-13905H wins 11. Its most decisive victories are in Passmark find prime numbers (122 versus 89, a 37.1% margin), floating point math (73434 versus 54447, 34.9%), physics (2054 versus 1578, 30.2%), and data encryption (20464 versus 16247, 26%). These results indicate a substantial advantage in numerical and physics-heavy workloads.

The Intel part also wins Cinebench R15 single-core by 14.4% (246 versus 215), integer math by 14.9% (101716 versus 88531), multithread by 13% (29779 versus 26350), data compression by 12.2% (354330 versus 315906), R23 multi-core by 9.4% (20034 versus 18316), R15 multi-core by 5.3% (2857 versus 2713), and random string sorting by 5.1% (37460 versus 35648).

The AMD Ryzen AI 7 450 wins 4 comparisons. Its strongest is Passmark single-thread, where it scores 3901 versus 3703, a 5.1% margin. It also wins extended instructions (22400 versus 21297, 4.9%) and Cinebench R23 single-core (2038 versus 2020, 0.9%). The Passmark singlethread result mirrors the single-thread result at 3901 versus 3703.

The pattern is consistent: the Intel part dominates in multi-threaded and math-heavy workloads, while the AMD part shows an edge in single-thread and extended instruction tests. The AMD part's single-thread win in R23 is narrow at 0.9%, suggesting the two are closely matched in lightly threaded Cinebench work, but the Intel part's 14.4% R15 single-core win complicates that picture. Across the two Cinebench versions, single-core results are split, while multi-core results consistently favor Intel.
