These wins, combined with the lower 28-watt TDP, make the P185 suitable for scenarios where power efficiency and integer-heavy processing are priorities.

The AMD Ryzen AI Max PRO 385 wins the majority of tests, including the largest margin in extended instructions at 15.6%. This suggests a strong capability for workloads that use advanced instruction sets. The 17.8% lead in prime number finding indicates an edge in mathematical computations that are not purely integer or floating point. The multithread score of 32,075 versus 31,817, while small, shows a consistent advantage in parallel processing. Data compression, random string sorting, and single-thread performance all go to the Max PRO 385 by narrow margins of 1.3%, 0.6%, and 0.5%, respectively.

The Max PRO 385 also offers a substantially larger memory bandwidth of 256.0 GB/s, which could benefit memory-intensive tasks, though the benchmark data does not explicitly measure memory-bound workloads. The 32 MB of shared L3 cache doubles the P185's 16 MB, potentially improving cache hit rates for certain data patterns. For users prioritizing the broader set of benchmark wins and the higher extended instructions score, the Max PRO 385 is the data-supported selection. For those focused on integer math, encryption, and lower power draw, the P185 delivers the stronger measured results.
