Where Each One Wins

Based on the recorded data, the AMD Ryzen 9 PRO 8945HS wins every benchmark category. The most pronounced advantages are in random string sorting (79.1%), data encryption (93.7%), and integer math (69.8%). These results indicate that the Ryzen 9 PRO 8945HS is the superior choice for workloads that rely on high memory throughput, cryptographic processing, and general integer computation. Its 16 threads, compared to 12 for the Ryzen AI 5 PRO 435, provide a clear edge in multithreaded scenarios, evidenced by the 59.1% lead in the passmark multithread test. The Ryzen 9 PRO 8945HS also benefits from a larger 16 MB shared L3 cache, which likely contributes to its strong showing in data-heavy tasks like compression and sorting.

The AMD Ryzen AI 5 PRO 435 does not record a single win in the head-to-head data. However, its closest performance to the Ryzen 9 PRO 8945HS is in the single-thread test, where it trails by only 4.3%. This suggests that for lightly threaded applications, the performance difference is minimal. The Ryzen AI 5 PRO 435 also operates at a lower 28 W TDP compared to 45 W for the Ryzen 9 PRO 8945HS, a specification that is not directly benchmarked but indicates a focus on power efficiency. The Ryzen AI 5 PRO 435 uses a Zen 5 architecture with an 80 KB L1 cache per core, which is larger than the 64 KB per core on the Ryzen 9 PRO 8945HS, potentially aiding in some single-core efficiency scenarios. The data shows no benchmark where the Ryzen AI 5 PRO 435 outperforms its rival.

The Verdict

The benchmark data directs a clear verdict: the AMD Ryzen 9 PRO 8945HS is the higher-performance processor. It wins all 11 head-to-head tests, with deltas ranging from 4.3% in single-thread to 93.7% in data encryption. Its average benchmark score of 41963 places it at the 88th percentile among all CPUs, while the Ryzen AI 5 PRO 435 has an average score of 37762, placing it at the 86th percentile. The Ryzen 9 PRO 8945HS also sits higher in the overall database ranking, with its average score slightly above the Intel Core i7-14700T (41914, delta 0.1%) and Intel Core i7-12850HX (41779, delta 0.4%).

The Ryzen AI 5 PRO 435, with an average score of 37762, is closely matched with the AMD Ryzen AI Embedded P132 (37804, delta -0.1%) and the Intel Core 5 211E (37829, delta -0.2%). It trails the Intel Core i5-13600K (37685, delta 0.2%) by a small margin.
