The single-thread results are the closest. Passmark_single_thread scores 3841 for the Ryzen AI 9 365 versus 3757 for the Ryzen AI 5 PRO 435, a modest 2.2% difference. The same 2.2% margin appears in passmark_singlethread. This indicates that while the Ryzen AI 9 365 has a higher boost clock (5.00 GHz versus 4.50 GHz), the per-core execution efficiency is nearly identical, and the Ryzen AI 5 PRO 435 remains competitive for single-threaded workloads.

The Ryzen AI 9 365 also has additional benchmark entries not present for the Ryzen AI 5 PRO 435: Cinebench R15 multicore (2842), Cinebench R15 singlecore (303), Cinebench R23 multicore (18698), Cinebench R23 singlecore (1992), Geekbench multicore (13760), and Geekbench singlecore (2253). These scores further confirm its multi-threaded strength, with the R23 multicore result exceeding the R15 multicore result by a factor of 6.6, indicating strong scaling across cores.

Where Each One Wins

The Ryzen AI 9 365 is the clear winner for all multi-threaded workloads. The data shows a 35.2% advantage in multithread, a 40.2% advantage in integer math, and a 41.6% advantage in physics. These are tasks that leverage the additional 4 cores and 8 threads directly. The 16 MB L3 cache likely contributes to the 34.3% lead in data compression and the 38.4% lead in encryption, as larger working sets can remain resident in cache. For rendering, simulation, compilation, or data processing, the Ryzen AI 9 365 is the superior part based on every recorded metric.

The Ryzen AI 5 PRO 435 does not win any benchmark, but it is not without merits. Its single-thread score of 3757 is within 2.2% of the Ryzen AI 9 365, meaning for lightly threaded applications such as office productivity, web browsing, or legacy software, the performance gap is negligible. The presence of ECC memory support makes it suitable for reliability-sensitive environments where data integrity is paramount, a feature the Ryzen AI 9 365 lacks entirely. Additionally, the Ryzen AI 5 PRO 435 has a lower boost clock (4.50 GHz versus 5.00 GHz), which may translate to more predictable power behavior, though the TDP is identical at 28 W.

The Ryzen AI 9 365 also aligns with an earlier release date (2024-06-30 versus 2026-01-04), indicating it has been available for a longer period in the market. The Ryzen AI 5 PRO 435, as a newer PRO-series part, targets commercial deployments with ECC and a smaller cache footprint. In terms of benchmark scores, the Ryzen AI 9 365 is the performance leader without exception, and the Ryzen AI 5 PRO 435 serves as a lower-core-count alternative for single-threaded and ECC-focused use cases.
