AMD Ryzen AI 7 345 vs AMD Ryzen AI 9 365 Comparison

The Verdict

The recorded data positions the AMD Ryzen AI 9 365 as the clear performance leader between these two mobile processors. Across 15 head-to-head benchmark comparisons, the Ryzen AI 9 365 wins 13, while the Ryzen AI 7 345 takes only 2. The average benchmark score tells the same story: the Ryzen AI 9 365 posts 40048 versus 29461 for the Ryzen AI 7 345, a gap of roughly 36 percent. The Ryzen AI 9 365 also sits in the 87th percentile of all CPUs in the database, while the Ryzen AI 7 345 lands in the 81st.

The Ryzen AI 7 345 does hold one meaningful edge in single-threaded PassMark testing, where it scores 3875 against 3841, a 0.9 percent advantage. That result appears twice in the dataset (passmark_single_thread and passmark_singlethread), confirming the consistency of the measurement. However, the Ryzen AI 9 365 counters with superior single-core results in Cinebench, scoring 303 in R15 and 1992 in R23 versus 271 and 1818 for the Ryzen AI 7 345.

Users seeking maximum multi-threaded throughput should select the Ryzen AI 9 365. Its 10 cores and 20 threads deliver substantially higher scores in every multi-core workload recorded. Users prioritizing the narrow PassMark single-thread metric might prefer the Ryzen AI 7 345, but the margin is small and the Cinebench single-core numbers favor the larger processor. For general productivity, content creation, or any workload that scales across cores, the data unequivocally favors the Ryzen AI 9 365.

Architecture Differences

Both processors belong to the Ryzen AI 300 generation and share the Zen 5 / Zen 5c architecture family, but they come from different codenames. The Ryzen AI 7 345 uses the Krackan Point design, while the Ryzen AI 9 365 uses Strix Point. The Ryzen AI 9 365 is explicitly listed with a "Zen 5" architecture string, while the Ryzen AI 7 345 does not carry a separate architecture field in the database.

The core counts differ substantially: the Ryzen AI 9 365 packs 10 cores and 20 threads, the Ryzen AI 7 345 offers 6 cores and 12 threads. The die size also differs, with the Ryzen AI 9 365 measuring 233 mm². No die size figure is recorded for the Ryzen AI 7 345, which suggests the Krackan Point design is physically smaller, though the database does not provide a number to confirm this.

Cache hierarchy differs most noticeably at the L3 level. The Ryzen AI 9 365 has 16 MB of L3 cache, four times the 4 MB found on the Ryzen AI 7 345. Per-core L1 and L2 caches are identical at 80 KB and 1 MB respectively. Both processors use the same PCIe generation (Gen 4), but the Ryzen AI 9 365 provides 16 lanes versus 14 lanes for the Ryzen AI 7 345.

The integrated graphics differ as well. The Ryzen AI 9 365 ships with the Radeon 880M, while the Ryzen AI 7 345 uses the Radeon 840M. Neither processor supports ECC memory, and both are locked multipliers, meaning overclocking is not available through the multiplier.

Specification Differences

The two processors share several core specifications: both use AMD Socket FP8, both are built on TSMC's 4 nm process, both have a 28 W TDP, and both support DDR5 and LPDDR5X memory. The memory bus is dual-channel for both, with identical 89.6 GB/s bandwidth. Both are mobile segment parts, currently active in production, and neither has a launch MSRP recorded.

The differences begin with core and thread counts: 10 cores and 20 threads for the Ryzen AI 9 365 versus 6 cores and 12 threads for the Ryzen AI 7 345. Base clocks match at 2.00 GHz, but boost clocks diverge, with the Ryzen AI 9 365 reaching 5.00 GHz versus 4.60 GHz for the Ryzen AI 7 345.

L3 cache differs by a factor of four: 16 MB on the Ryzen AI 9 365 versus 4 MB on the Ryzen AI 7 345. PCIe lane count also differs, with 16 lanes on the Ryzen AI 9 365 and 14 on the Ryzen AI 7 345. The integrated graphics differ (Radeon 880M versus Radeon 840M), as does the die size (233 mm² recorded only for the Ryzen AI 9 365).

Release dates differ by roughly six months. The Ryzen AI 9 365 entered the market on 2024-06-30, while the Ryzen AI 7 345 arrived on 2025-01-14. The part numbers also differ: 100-000001530 for the Ryzen AI 9 365 and 100-000002122 for the Ryzen AI 7 345.

PassMark multi-thread results reinforce the trend. The Ryzen AI 9 365 scores 29467 versus 19927 for the Ryzen AI 7 345, a 32.4 percent lead. Integer math shows a 37.7 percent advantage (101831 versus 63475), while floating-point math favors the Ryzen AI 9 365 by 32.1 percent (62802 versus 42621). Data compression tests show a 33 percent gap (354510 versus 237484), and data encryption shows a 35.4 percent gap (18297 versus 11814).

The prime number search workload reveals the largest relative difference. The Ryzen AI 9 365 scores 117 versus 62 for the Ryzen AI 7 345, a 47 percent advantage. Physics simulation tests show a 36.1 percent gap (1704 versus 1089), while random string sorting shows a 35.5 percent gap (39447 versus 25435). Extended instruction tests (likely AVX-related) show a 32.3 percent advantage for the Ryzen AI 9 365 (25113 versus 17003).

Single-core results are closer. Cinebench R15 single-core gives the Ryzen AI 9 365 a 10.6 percent edge (303 versus 271), while R23 single-core shows an 8.7 percent gap (1992 versus 1818). However, the PassMark single-thread test flips the result: the Ryzen AI 7 345 scores 3875 versus 3841, a 0.9 percent win. This appears twice in the dataset, confirming the measurement.

The overall win count stands at 13 for the Ryzen AI 9 365 and 2 for the Ryzen AI 7 345. The average benchmark scores place the Ryzen AI 9 365 near desktop-class competitors: it sits within 0.1 percent of the AMD Ryzen 7 7700 and within 0.7 percent of the Intel Core i9-13905H. The Ryzen AI 7 345, by contrast, matches the AMD Ryzen 7 3800X almost exactly (0 percent delta) and trails the Intel Core i5-13500HX by 0.7 percent. These nearest-rival comparisons contextualize the performance tier: the Ryzen AI 9 365 competes with upper-mid-range desktop and high-end mobile parts, while the Ryzen AI 7 345 aligns with older desktop processors and mid-range mobile chips.
