Its DDR4 memory support may also be relevant for systems with existing DDR4 memory. The database does not show any benchmark where the Ryzen 3 PRO 5355GE outperforms the Ryzen AI 9 365.

The Ryzen AI 9 365 wins every performance category in the recorded data. It is the choice for multi-threaded rendering workloads, as shown by Cinebench R15 and R23 multi-core results. It is the choice for data compression, encryption, and extended instruction workloads, where its margins range from -47.7% to -58.7%. It is the choice for floating-point and integer math workloads, with deltas of -61.6% and -56.1% respectively. It is also the choice for single-threaded workloads, with the smallest recorded margin of -19.6% in PassMark single-thread.

The Ryzen AI 9 365 additionally offers higher memory bandwidth at 89.6 GB/s compared to 51.2 GB/s, newer DDR5 and LPDDR5X memory support, PCIe Gen 4 instead of Gen 3, and a more advanced 4 nm process node. Its Radeon 880M integrated graphics replaces the older Radeon Vega 6. The lower TDP of 28 watts compared to 35 watts means the Ryzen AI 9 365 delivers substantially higher performance while consuming less power according to the listed TDP values.

The percentile data reinforces the performance hierarchy. The Ryzen AI 9 365 sits at the 87th percentile of all CPUs, while the Ryzen 3 PRO 5355GE sits at the 71st percentile. The nearest rival comparisons confirm that the Ryzen AI 9 365 competes with processors like the AMD Ryzen 7 7700 and Intel Core i9-13905H, while the Ryzen 3 PRO 5355GE competes with the AMD Ryzen 5 4600G and AMD Ryzen 3 8300GE. For any workload where compute performance is the deciding factor, the recorded data points to the Ryzen AI 9 365 without exception.
