Architecture Differences

The two processors come from different AMD generations and use different underlying designs. The Ryzen 7 PRO 8840U is an 8000 series part built on the Zen 4 architecture, codenamed Hawk Point. It uses 8 cores and 16 threads. The Ryzen AI 9 365 belongs to the Ryzen AI 300 series, built on Zen 5 and Zen 5c, codenamed Strix Point. It uses 10 cores and 20 threads. Both are manufactured on a 4 nm process at TSMC.

The die sizes differ substantially. The Ryzen 7 PRO 8840U has a die size of 178 mm² and contains 25,000 million transistors. The Ryzen AI 9 365 has a larger die at 233 mm², though the transistor count for this chip is not recorded in the database. Clock speeds also differ. The Ryzen 7 PRO 8840U has a base clock of 3.30 GHz and a boost clock of 5.10 GHz. The Ryzen AI 9 365 has a lower base clock of 2.00 GHz and a boost clock of 5.00 GHz. Both parts carry a 28 W TDP and are unlocked in their multipliers.

Cache configurations follow the architectural split. The Ryzen 7 PRO 8840U provides 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The Ryzen AI 9 365 provides 80 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of L3 cache. The larger per-core L1 cache on the Ryzen AI 9 365 reflects the newer Zen 5 design.

Memory support is similar but not identical. Both chips support dual-channel memory with a recorded bandwidth of 89.6 GB/s. The Ryzen 7 PRO 8840U supports DDR5 and includes ECC memory support. The Ryzen AI 9 365 supports both DDR5 and LPDDR5X, but does not include ECC support. The PCIe configurations also differ. The Ryzen 7 PRO 8840U provides Gen 4 with 20 lanes (CPU only), while the Ryzen AI 9 365 provides Gen 4 with 16 lanes (CPU only). The sockets are different as well: the Ryzen 7 PRO 8840U uses AMD Socket FP7, and the Ryzen AI 9 365 uses AMD Socket FP8. The integrated graphics differ, with the Ryzen 7 PRO 8840U carrying the Radeon 780M and the Ryzen AI 9 365 carrying the Radeon 880M. The Ryzen 7 PRO 8840U has two recorded part numbers, 100-000001317 (FP7r2) and 100-000001377 (FP7), while the Ryzen AI 9 365 has a single part number, 100-000001530. The Ryzen 7 PRO 8840U was released on 2024-04-15, and the Ryzen AI 9 365 was released on 2024-06-30.

Where Each One Wins

The Ryzen 7 PRO 8840U wins in Cinebench R23, both single-core and multi-core. The single-core result, a 43.5% lead, is the most lopsided outcome in the entire dataset. This suggests the Zen 4 chip at its higher boost clock of 5.10 GHz delivers strong performance in this specific rendering benchmark, despite having two fewer cores and four fewer threads. The multi-core R23 win, at 8.3%, is narrower but still clear. For users running Cinebench R23 specifically, the Ryzen 7 PRO 8840U is the better choice according to the recorded data.

The Ryzen AI 9 365 wins everywhere else. Its 10-core, 20-thread configuration gives it a clear advantage in the Passmark multi-thread test, where it leads by 19.1%. The physics test shows a 31.1% advantage, and the find prime numbers test shows a 35% advantage. These results point to a chip that handles parallel integer workloads and physics calculations with considerably more headroom. The data compression and extended instructions tests also favor the Ryzen AI 9 365 by more than 23%, indicating strong performance in encryption, compression, and SIMD-style workloads. The single-thread Passmark result is closer at 5.2%, but still favors the Ryzen AI 9 365.

The Cinebench R15 results add a wrinkle. In the older version of Cinebench, the Ryzen AI 9 365 wins both single-core (5%) and multi-core (28.2%). This contrasts with the R23 results, where the Ryzen 7 PRO 8840U wins. The data suggests that the two chips respond differently across Cinebench versions, with the Ryzen 7 PRO 8840U performing better in R23 and the Ryzen AI 9 365 performing better in R15. Users should note that benchmark selection matters when evaluating these two processors.

The Verdict

The data points to two different profiles. The AMD Ryzen AI 9 365 is the stronger overall processor. It wins 13 of 15 head-to-head tests, holds a higher average benchmark score (40048 versus 32233), and ranks at the 87th percentile of all CPUs compared with the 83rd percentile for the Ryzen 7 PRO 8840U. Its nearest rivals include the AMD Ryzen 7 7700 and Intel Core i9-13905H, which places it in a higher performance tier. The Ryzen 7 PRO 8840U, by contrast, sits alongside the Intel Core i5-14400 and Intel Core i7-12800H.

The Ryzen 7 PRO 8840U is the choice only for workloads that resemble Cinebench R23, particularly the single-core variant where it leads by 43.5%. That is a narrow but real advantage. For almost every other recorded workload, including compression, encryption, math operations, physics, and general multi-threading, the Ryzen AI 9 365 delivers higher scores, often by double-digit margins. The Ryzen AI 9 365 also offers more cores and threads, a larger L1 cache per core, and support for LPDDR5X memory, while the Ryzen 7 PRO 8840U counters with ECC memory support and more PCIe lanes. The Ryzen 7 PRO 8840U also has a higher boost clock, 5.10 GHz versus 5.00 GHz, which likely contributes to its R23 single-core win.

Both parts carry the same 28 W TDP and are production-active mobile processors. The Ryzen AI 9 365 is a newer release, dated 2024-06-30 versus 2024-04-15 for the Ryzen 7 PRO 8840U. For general-purpose productivity and compute-heavy tasks, the Ryzen AI 9 365 is the stronger part according to the benchmark data. For users specifically targeting Cinebench R23 performance, the Ryzen 7 PRO 8840U holds the advantage.
