Single-thread PassMark shows a 15.6% advantage for the Ryzen AI 9 365 (3841 versus 3241).

The sole win for the AMD Ryzen 5 PRO 5655G comes in Cinebench R23 single-core, where it scores 2435 versus 1992, a 22.2% advantage. This is notable because the Ryzen 5 PRO 5655G has a higher base clock (3.90 GHz versus 2.00 GHz) and only a 0.60 GHz lower boost clock, so in a workload that does not sustain multi-core boost, its higher baseline frequency pays off.

Where Each One Wins

The AMD Ryzen AI 9 365 wins in nearly every measured category. It is the stronger processor for multi-core rendering, as shown by its 7.7% lead in Cinebench R23 multi-core and 38.8% lead in Cinebench R15 multi-core. It is also the stronger processor for scientific and mathematical workloads, with large leads in floating point math, integer math, and prime number finding. Data-heavy tasks like compression, encryption, and random string sorting all favor the Ryzen AI 9 365 by double-digit margins. Physics simulation shows the largest gap, with the Ryzen AI 9 365 nearly 60% ahead.

The Ryzen AI 9 365 also wins in general single-threaded performance according to PassMark, with a 15.6% lead. Its 5.00 GHz boost clock and newer Zen 5 architecture likely contribute to this result, though the database does not provide direct architectural analysis.

The AMD Ryzen 5 PRO 5655G wins only in Cinebench R23 single-core, where its 2435 score beats the Ryzen AI 9 365's 1992 by 22.2%. This makes it the better choice for workloads that are specifically sensitive to the Cinebench R23 single-thread metric. Additionally, the Ryzen 5 PRO 5655G is the only option for AM4 desktop platforms and DDR4 memory, and it supports ECC memory, which the Ryzen AI 9 365 does not. Its desktop market segment and 65 W TDP also make it a fit for traditional desktop builds, whereas the Ryzen AI 9 365 is a mobile part with a 28 W TDP.

In summary, the Ryzen AI 9 365 is the data-backed choice for users who prioritize multi-threaded throughput, math performance, and memory bandwidth. The Ryzen 5 PRO 5655G is the data-backed choice for users on AM4 platforms, those needing ECC memory, or those targeting the specific Cinebench R23 single-core workload.
