AMD Ryzen 7 PRO 8840U vs AMD Ryzen AI 7 PRO 360 Comparison

AMD Ryzen AI 7 PRO 360 vs AMD Ryzen 7 PRO 8840U: two 8-core, 16-thread mobile processors aimed at professional laptops, but the data shows they are not equal. The Ryzen 7 PRO 8840U, based on the older Zen 4 architecture, dominates the majority of benchmark comparisons, while the Ryzen AI 7 PRO 360, built on Zen 5, only manages to secure a few specific wins. This analysis breaks down the recorded head-to-head results to help you decide which one fits your workload.

Head-to-Head Benchmarks

The benchmark database shows a clear pattern: the AMD Ryzen 7 PRO 8840U wins 11 of the 15 recorded comparisons, while the AMD Ryzen AI 7 PRO 360 takes only 4. The most dramatic differences appear in Cinebench tests. In Cinebench R23 multicore, the 8840U scores 20254 against the 360's 13794, a massive 31.9% lead. The single-core R23 test tells a similar story, with the 8840U at 2859 versus 1958, a 31.5% advantage. These are not marginal differences; they represent a substantial performance gap in both heavily threaded and lightly threaded rendering workloads.

The Ryzen 7 PRO 8840U also wins in the older Cinebench R15 tests, though by smaller margins. It scores 2041 versus 2023 in multicore, a 0.9% lead, and 288 versus 271 in single-core, a 5.9% advantage. PassMark results reinforce the 8840U's dominance. In integer math, the 8840U scores 88339 versus 77414, a 12.4% lead, and in floating point math it posts 50746 against 46996, a 7.4% win. The 8840U also leads in data encryption (16441 vs 13264, a 19.3% gap), random string sorting (33109 vs 28390, a 14.3% gap), and data compression (272664 vs 256603, a 5.9% gap). Its multithread score of 23850 beats the 360's 22125 by 7.2%, and its extended instructions score of 19132 beats 18029 by 5.8%.

The Ryzen AI 7 PRO 360's wins are narrower but worth noting. In PassMark single-thread tests, it scores 3862 versus 3641, a 6.1% lead, which indicates a higher peak frequency in lightly threaded scenarios. It also wins the physics test with 1257 versus 1174, a 7.1% advantage, and ties the 8840U at 76 in the find prime numbers test. These results suggest the 360's Zen 5 architecture offers some efficiency in specific instruction paths, but not enough to overcome the 8840U's overall throughput.

Architecture Differences

The two processors come from different architectural generations. The Ryzen AI 7 PRO 360 uses the Zen 5 architecture, codenamed Strix Point, while the Ryzen 7 PRO 8840U uses Zen 4, codenamed Hawk Point. Both are built on TSMC's 4 nm process, so the node is identical. The die size differs, with the 360 measuring 233 mm² versus the 8840U's 178 mm², and the 8840U has a listed transistor count of 25,000 million, while the 360's transistor count is not recorded in the database.

Cache layouts are a key differentiator. The 360 offers 80 KB of L1 cache per core and 1 MB of L2 per core, with 8 MB of L3 cache. The 8840U has 64 KB of L1 per core and 1 MB of L2 per core, but its L3 cache is 16 MB shared. That double-sized L3 pool likely explains why the 8840U performs better in many memory-sensitive workloads, even with the older core design. The 360's larger L1 per core helps in specific single-thread tasks, but the 8840U's shared L3 provides more total cache.

Socket and platform support also differ. The 360 uses AMD Socket FP8, while the 8840U uses AMD Socket FP7. Both support dual-channel memory with 89.6 GB/s bandwidth, and both support ECC memory. The 8840U lists DDR5 memory support, while the 360 supports DDR5 and LPDDR5X. PCIe lanes differ, with the 8840U offering Gen 4 with 20 lanes versus the 360's Gen 4 with 16 lanes, which may matter for expandability in docking stations or external GPUs. Integrated graphics also differ: the 360 has a Radeon 880M, while the 8840U has a Radeon 780M.

Where Each One Wins

The AMD Ryzen 7 PRO 8840U is the clear winner for compute-heavy tasks. Its 31.9% lead in Cinebench R23 multicore makes it a better choice for video rendering, 3D modeling, and batch processing. The 12.4% lead in integer math and 7.4% lead in floating point math indicate stronger general-purpose number crunching. Its 19.3% advantage in data encryption is a decisive factor for workloads involving file encryption, secure communications, or virtual private network processing. The 14.3% win in random string sorting suggests better performance in database operations and text manipulation. For users running sustained multithreaded loads, the 8840U is the pick.

The AMD Ryzen AI 7 PRO 360 wins in specific scenarios. Its 6.1% advantage in PassMark single-thread tests means it handles quick, sequential tasks with slightly better responsiveness, such as opening applications, light coding, or spreadsheet work. The 7.1% win in physics calculations could benefit simulation software that relies on that specific instruction path. Its larger L1 cache per core and newer Zen 5 architecture may also offer better energy efficiency per instruction, though the database does not record power consumption. For users who prioritize single-thread latency or run workloads that hit the physics test pattern, the 360 is the better option.

The Verdict

The data points decisively toward the AMD Ryzen 7 PRO 8840U for most buyers. It wins 11 out of 15 benchmarks, including the most demanding ones. The 31.9% gap in Cinebench R23 multicore is too large to ignore for anyone doing CPU-bound work. Its double L3 cache and higher base and boost clocks give it a practical edge in real-world applications. If you are choosing between these two for a workstation laptop, the 8840U is the safer bet for performance.

The AMD Ryzen AI 7 PRO 360 is a niche pick. It wins in single-thread PassMark and physics, and it offers a newer architecture, but the benchmark evidence does not support it as a general performance leader. Its lower
