Architecture Differences

The Ryzen AI 9 365 uses the Zen 5 architecture on the Strix Point codename, built on a 4 nm process at TSMC. Its die size measures 233 mm². The chip integrates 10 cores and 20 threads, arranged in the Ryzen AI 300 generation which combines Zen 5 and Zen 5c cores. Each core carries 80 KB of L1 cache and 1 MB of L2 cache, with a shared 16 MB L3 pool.

The Ryzen Embedded 8640U uses the Zen 4 architecture on the Hawk Point codename, also built on a 4 nm process at TSMC. Its die is smaller at 178 mm², and the chip contains 25,000 million transistors. It offers 6 cores and 12 threads from the Ryzen Embedded generation. Each core has 64 KB of L1 cache and 1 MB of L2 cache, with 16 MB of shared L3 cache.

Both processors fit the AMD Socket FP8 and share a 28 W TDP. Memory bandwidth is identical at 89.6 GB/s over dual-channel interfaces. The Ryzen AI 9 365 supports both DDR5 and LPDDR5X memory, while the Embedded 8640U supports DDR5 only. The Ryzen AI 9 365 does not support ECC memory; the Embedded 8640U does.

PCI Express connectivity differs: the Ryzen AI 9 365 provides Gen 4 with 16 lanes from the CPU, while the Embedded 8640U provides Gen 4 with 20 lanes. Integrated graphics also differ, with the Ryzen AI 9 365 featuring the Radeon 880M and the Embedded 8640U featuring the Radeon 760M.

The Ryzen AI 9 365 clocks at 2.00 GHz base and 5.00 GHz boost. The Embedded 8640U runs at a higher 3.50 GHz base but a slightly lower 4.90 GHz boost. Neither chip has an unlocked multiplier.

The Verdict

The data shows two processors aimed at different roles. The Ryzen AI 9 365 delivers significantly more cores, threads, and cache per core, with a larger die and newer Zen 5 architecture. Its benchmark results place it in the 87th percentile, competing within 1% of mid-range desktop and mobile processors like the Ryzen 7 7700 and Core i9-13905H.

The Ryzen Embedded 8640U targets embedded applications with ECC memory support and extra PCIe lanes. Its 6 cores and 12 threads, while fewer, run at a higher base clock of 3.50 GHz, which suits sustained single-threaded workloads. The 50th percentile ranking indicates mainstream-level performance rather than high-end.

Users who need maximum multi-threaded throughput, larger L3 cache per core, and the newer architecture should select the Ryzen AI 9 365. The benchmark record confirms strong results across Cinebench, Geekbench, and PassMark suites. Users who require ECC memory validation, additional PCIe lanes for peripherals, and a smaller physical die should select the Ryzen Embedded 8640U.

The Ryzen AI 9 365 has a clear advantage in core count, thread count, and per-core cache. The Embedded 8640U counters with higher base clock, ECC support, and more PCIe lanes. Both share the same TDP, socket, process node, foundry, memory bandwidth, and boost clock within 0.10 GHz.
