The two processors come from different AMD generations. The Ryzen 9 PRO 8945HS uses Zen 4 architecture under the Hawk Point codename, part of the Ryzen 9 generation. The Ryzen AI 9 365 uses Zen 5 architecture under the Strix Point codename, part of the Ryzen AI 300 generation. Both are built on a 4 nm process at TSMC, but the die sizes differ: the Ryzen 9 PRO 8945HS measures 178 mm² with 25,000 million transistors, while the Ryzen AI 9 365 measures 233 mm² with transistor count not recorded in the database.

Core counts differ meaningfully. The Ryzen 9 PRO 8945HS has 8 cores and 16 threads, while the Ryzen AI 9 365 has 10 cores and 20 threads. The Ryzen AI 9 365 combines Zen 5 and Zen 5c cores in a hybrid arrangement. The Ryzen 9 PRO 8945HS has uniform Zen 4 cores. Base clocks separate the two strongly: the Ryzen 9 PRO 8945HS runs at 4.00 GHz base with a 5.20 GHz boost, while the Ryzen AI 9 365 runs at 2.00 GHz base with a 5.00 GHz boost. The Ryzen AI 9 365's low base clock reflects its hybrid core design and lower power envelope.

Thermal design power differs. The Ryzen 9 PRO 8945HS is rated at 45 W TDP, while the Ryzen AI 9 365 is rated at 28 W TDP. The Ryzen 9 PRO 8945HS uses AMD Socket FP7, and the Ryzen AI 9 365 uses AMD Socket FP8. Cache configurations also differ.

Both processors are locked (multiplier not unlocked), both target the mobile market segment, and both remain in active production as of the database records. The Ryzen 9 PRO 8945HS launched on April 15, 2024, while the Ryzen AI 9 365 launched on June 30, 2024.

The Verdict

The recorded data supports a clear split. The AMD Ryzen 9 PRO 8945HS is the stronger all-around processor for compute-heavy workloads. Its Cinebench R23 multi-core score of 25165 versus 18698 represents a 34.6% advantage, and its single-core Cinebench R23 score of 3552 versus 1992 is a 78.3% advantage. These are not marginal differences. Applications that rely on sustained multi-threaded execution, such as 3D rendering, video encoding, or software compilation, will show large performance gains on the Ryzen 9 PRO 8945HS.

The Ryzen AI 9 365 does not match the Ryzen 9 PRO 8945HS in most benchmarks, but its wins are not trivial. The 10.8% lead in Cinebench R15 multi-core and the 16.1% lead in PassMark physics suggest that its 10-core, 20-thread configuration can outperform in specific parallel workloads, particularly those that are short-lived or scale well with core count. The 22.2% win in find prime numbers indicates an advantage in certain integer-heavy algorithms.

The Ryzen AI 9 365 has a lower TDP of 28 W versus 45 W for the Ryzen 9 PRO 8945HS. That difference matters for system design, since a lower TDP allows thinner chassis and longer battery life in mobile devices. The Ryzen AI 9 365 also supports LPDDR5X memory, which is common in compact laptops, while the Ryzen 9 PRO 8945HS supports ECC memory, which suits workstation or professional use cases.

The percentile rankings place the Ryzen 9 PRO 8945HS at the 88th percentile among all CPUs, with an average benchmark score of 41963. The Ryzen AI 9 365 sits at the 87th percentile with an average benchmark score of 40048. The nearest rivals for the Ryzen 9 PRO 8945HS include the Intel Core i7-14700T at 41914 (0.1% higher) and the AMD Ryzen 5 7400 at 42055 (0.2% lower).

Head-to-Head Benchmarks

The largest single benchmark gap in the comparison is Cinebench R23 single-core. The Ryzen 9 PRO 8945HS scores 3552, and the Ryzen AI 9 365 scores 1992, a 78.3% difference. This is the defining advantage for the Ryzen 9 PRO 8945HS in any workload that does not scale across cores. The R15 single-core test shows a similar pattern at 357 versus 303, a 17.8% lead. These results are consistent with the higher boost clock of 5.20 GHz versus 5.00 GHz and the uniform Zen 4 core design.

Cinebench R23 multi-core reverses the core-count expectation. Despite having 10 cores versus 8, the Ryzen AI 9 365 scores only 18698, while the Ryzen 9 PRO 8945HS scores 25165. The 34.6% margin suggests that the Ryzen AI 9 365's hybrid Zen 5 / Zen 5c configuration does not sustain multi-threaded throughput as effectively as the Ryzen 9 PRO 8945HS's eight full Zen 4 cores. The R15 multi-core test tells a different story: the Ryzen AI 9 365 wins 2842 to 2536, a 10.8% edge. The difference between the R15 and R23 multi-core results may reflect workload duration and thermal behavior, since the Ryzen AI 9 365 has a 28 W TDP.

PassMark results cluster more closely. Data compression goes to the Ryzen 9 PRO 8945HS at 368884 versus 354510, a 4.1% margin. Data encryption shows a larger gap at 21820 versus 18297, a 19.3% advantage. Extended instructions favor the Ryzen 9 PRO 8945HS by 10.4% (27714 versus 25113). Random string sorting goes to the Ryzen 9 PRO 8945HS at 44668 versus 39447, a 13.2% margin. Floating point math is nearly even at 63490 versus 62802, a 1.1% lead for the Ryzen 9 PRO 8945HS. Integer math is also close at 103390 versus 101831, a 1.5% edge. PassMark multithread favors the Ryzen 9 PRO 8945HS at 30378 versus 29467, a 3.1% margin. PassMark single-thread and singlethread both show 3920 versus 3841, a 2.1% lead.

The Ryzen AI 9 365's wins are narrower in overall impact. PassMark physics shows 1704 versus 1430, a 16.1% advantage. Find prime numbers shows 117 versus 91, a 22.2% advantage. These wins indicate that the extra cores and Zen 5 architecture provide real benefits in specific computational patterns, but they do not offset the broad lead held by the Ryzen 9 PRO 8945HS across the rest of the benchmark suite.
