Architecture Differences

The AMD Ryzen AI 5 PRO 340 belongs to the Krackan Point codename family within the Ryzen AI PRO 300 generation, which uses a mix of Zen 5 and Zen 5c cores. The AMD Ryzen AI 9 365 belongs to the Strix Point codename family within the Ryzen AI 300 generation, also using Zen 5 and Zen 5c cores. Both are built on the same 4 nm TSMC process and use the same AMD Socket FP8.

The core configurations differ substantially. The Ryzen AI 5 PRO 340 provides 6 cores and 12 threads, while the Ryzen AI 9 365 provides 10 cores and 20 threads. This difference in core count drives most of the performance gap in multithreaded workloads. The die size also differs: 195 mm² for the Ryzen AI 5 PRO 340 versus 233 mm² for the Ryzen AI 9 365, reflecting the additional silicon for extra cores and cache.

Cache hierarchy shows a clear distinction in L3 capacity. The Ryzen AI 5 PRO 340 carries 8 MB of L3 cache, while the Ryzen AI 9 365 carries 16 MB of L3 cache. Both share the same per-core L1 (80 KB) and L2 (1 MB) allocations. The larger L3 on the Ryzen AI 9 365 benefits workloads that repeatedly access a working set larger than 8 MB.

The integrated graphics differ as well: Radeon 840M on the Ryzen AI 5 PRO 340 versus Radeon 880M on the Ryzen AI 9 365. This indicates a higher-tier iGPU on the Ryzen AI 9 365, though the database does not include separate graphics benchmarks. ECC memory support is exclusive to the Ryzen AI 5 PRO 340, which may matter for specific professional or reliability-focused use cases.

Both processors share the same base clock of 2.00 GHz, but the boost clock differs: 4.80 GHz for the Ryzen AI 5 PRO 340 and 5.00 GHz for the Ryzen AI 9 365. Both have a 28 W TDP and use dual-channel memory with 89.6 GB/s bandwidth. PCIe support is identical at Gen 4 with 16 CPU lanes.

Head-to-Head Benchmarks

The Verdict

The data points to a clear performance hierarchy. The AMD Ryzen AI 9 365 is the stronger processor in every benchmark category recorded, with its largest advantages in multithreaded workloads. The 10-core, 20-thread configuration delivers roughly 35% to 39% higher scores across Cinebench and PassMark multithread tests compared to the 6-core, 12-thread Ryzen AI 5 PRO 340.

For single-threaded tasks, the gap narrows to between 2.2% and 9.5%, depending on the benchmark. The Ryzen AI 9 365's 5.00 GHz boost clock versus 4.80 GHz gives it a modest edge in lightly threaded applications, but the per-core Zen 5 architecture appears similar in efficiency.

The Ryzen AI 5 PRO 340 should be chosen when ECC memory support is a requirement, as the Ryzen AI 9 365 lacks that feature. The Ryzen AI 5 PRO 340 also uses a smaller die (195 mm² versus 233 mm²), which may indicate lower manufacturing complexity, though the database does not include power efficiency measurements beyond the shared 28 W TDP.

The Ryzen AI 9 365 should be chosen for raw compute performance, particularly for rendering, data compression, encryption, and physics workloads where the core count advantage translates directly into higher throughput. Its 87th percentile ranking versus the 80th percentile for the Ryzen AI 5 PRO 340 confirms its placement in the higher tier of mobile processors.

Where Each One Wins

The AMD Ryzen AI 9 365 wins in every recorded benchmark category. Its strongest relative advantages appear in Cinebench R15 multicore (38.7% ahead), Cinebench R23 multicore (38.3% ahead), data encryption (38.7% ahead), and random string sorting (38.3% ahead). These workloads scale with core count and thread count, which explains the consistent margin.

The AMD Ryzen AI 5 PRO 340 has no benchmark wins in the database, but it holds specific feature advantages. ECC memory support is exclusive to this chip, making it the appropriate choice for systems that require error-correcting memory. Its smaller die size of 195 mm² versus 233 mm² may also be relevant for compact mobile designs, though the database does not provide chassis-level measurements.

For single-threaded responsiveness, the Ryzen AI 9 365 still leads, but by a much smaller margin (2.2% in PassMark single-thread, 8.9% in Cinebench R15 single-core, 9.5% in Cinebench R23 single-core). The Ryzen AI 5 PRO 340 remains competitive in lightly threaded office and web workloads where the 4.80 GHz boost clock provides adequate performance.

In multithreaded rendering, scientific computing, and data processing, the Ryzen AI 9 365 is the clear choice. Its PassMark multithread score of 29467 versus 19215, plus its 10-core configuration, delivers roughly a third more throughput across the board. The nearest rival data shows the Ryzen AI 9 365 performing near the AMD Ryzen 7 7700 (delta -0.1%), while the Ryzen AI 5 PRO 340 performs near the AMD Ryzen 7 5800X3D (delta 0.1%), putting these two chips in different performance classes entirely.
