Where Each One Wins

The data does not offer any workload category where the AMD Ryzen AI 7 445 comes out ahead. Every recorded benchmark, from Cinebench rendering to PassMark math and data tests, favors the Ryzen 9 PRO 8945HS. The closest contest is single-thread performance, where the Ryzen AI 7 445 trails by only 9.2%, suggesting that in lightly threaded tasks the gap narrows considerably.

For the Ryzen 9 PRO 8945HS, the strongest performance advantages appear in heavily parallel workloads. The Cinebench R23 multi-core test shows a 137.6% lead, and the data encryption test shows a 107.4% lead. These results indicate that the Ryzen 9 PRO 8945HS is particularly well suited for rendering, encryption, compression, and other tasks that scale with core count and thread count.

The Ryzen 9 PRO 8945HS also shows a strong lead in single-core rendering, with a 96.7% delta in Cinebench R23 single-core. This suggests that the advantage is not purely a matter of having more cores; the Ryzen 9 PRO 8945HS also delivers higher performance per thread in these workloads. The PassMark single-thread test, however, tells a slightly different story, with only a 9.2% delta, indicating that the gap in general single-threaded integer work is much smaller than in rendering-specific single-thread tests.

For practical use, the Ryzen 9 PRO 8945HS is the clear choice for multi-threaded productivity, content creation, and any workload that can use 16 threads. The Ryzen AI 7 445 remains competitive in lightly threaded tasks but falls far behind in anything that stresses multiple cores simultaneously.

The Verdict

The benchmark data points to a clear overall winner: the AMD Ryzen 9 PRO 8945HS. It wins all 15 head-to-head tests, holds a 137.6% lead in Cinebench R23 multi-core, and delivers a 67.7% advantage in PassMark multi-thread performance. Its 88th percentile ranking among all CPUs, compared to the 79th percentile for the Ryzen AI 7 445, reflects the large average benchmark score gap of 41,963 versus 26,936.

The Ryzen AI 7 445 offers a lower TDP at 28 W versus 45 W, which suggests it is positioned for more power-conscious mobile designs. It also supports LPDDR5X memory and uses the newer Zen 5 architecture. However, the recorded data does not show any performance category where this translates into a win. The closest it comes is the PassMark single-thread test, where the 9.2% delta is the smallest gap in the entire comparison.

For users prioritizing multi-threaded performance, rendering, encryption, compression, and general productivity, the Ryzen 9 PRO 8945HS is the stronger choice based on the data. The Ryzen AI 7 445 remains an option for systems where the lower TDP and memory flexibility matter more than raw benchmark scores. The recorded numbers, however, place the Ryzen 9 PRO 8945HS firmly ahead in every measured workload.
