AMD Ryzen AI 7 450 vs AMD Ryzen AI 9 365 Comparison

AMD Ryzen AI 9 365 and AMD Ryzen AI 7 450 are both 28 W mobile processors built on TSMC's 4 nm process, but they target different segments of the laptop market. The Ryzen AI 9 365 is the higher-tier part with 10 cores and 20 threads, while the Ryzen AI 7 450 offers 8 cores and 16 threads. Benchmark results show a clear split: the Ryzen AI 9 365 wins 12 of 15 head-to-head tests, but the Ryzen AI 7 450 takes the single-threaded crown in two key workloads. The recorded data indicates that the Ryzen AI 9 365 is the multi-threaded workhorse, while the Ryzen AI 7 450 offers a slightly sharper single-core edge despite fewer cores.

Where Each One Wins

The Ryzen AI 9 365 dominates in heavily threaded workloads. In Cinebench R15 multi-core, it scores 2842 against 2713 for the Ryzen AI 7 450, a 4.8% advantage. The gap widens in PassMark multi-thread testing, where the Ryzen AI 9 365 posts 29467 versus 26350, an 11.8% lead. Data compression shows a similar story: the Ryzen AI 9 365 scores 354510, which is 12.2% higher than the 315906 of the Ryzen AI 7 450. Integer math also favors the larger chip, with 101831 against 88531, a 15% margin. Floating-point math follows suit, with the Ryzen AI 9 365 at 62802 versus 54447, a 15.3% advantage.

The Ryzen AI 7 450 wins the single-thread battles that matter most for responsiveness. In Cinebench R23 single-core, it scores 2038 versus 1992 for the Ryzen AI 9 365, a 2.3% edge. PassMark single-thread testing confirms this, with the Ryzen AI 7 450 at 3901 against 3841, a 1.5% difference. The Ryzen AI 9 365 does win Cinebench R15 single-core by a massive 40.9% margin (303 versus 215), but that result is an outlier compared to the modern single-thread tests. For everyday tasks like web browsing, office work, and light productivity, the Ryzen AI 7 450's higher boost clock of 5.10 GHz appears to give it a slight but consistent advantage.

Architecture Differences

Both processors use the Zen 5 architecture, but they belong to different generations and codenames. The Ryzen AI 9 365 is from the Ryzen AI 300 series with the codename Strix Point, while the Ryzen AI 7 450 is from the Ryzen AI 400 series with the codename Gorgon Point. Both use a hybrid design of Zen 5 and Zen 5c cores, and both are built on TSMC's 4 nm process. The Ryzen AI 9 365 has a larger die at 233 mm², while the Ryzen AI 7 450 measures 195 mm².

The core counts differ significantly: the Ryzen AI 9 365 has 10 cores and 20 threads, while the Ryzen AI 7 450 has 8 cores and 16 threads. Cache configuration also diverges. Both have 80 KB of L1 cache per core and 1 MB of L2 cache per core, but the L3 cache is double on the Ryzen AI 9 365: 16 MB versus 8 MB. This larger L3 cache likely contributes to the Ryzen AI 9 365's wins in data-heavy workloads like compression and encryption.

The integrated graphics differ as well. The Ryzen AI 9 365 pairs with a Radeon 880M, while the Ryzen AI 7 450 uses a Radeon 860M. Memory support is identical: both support DDR5 and LPDDR5X with dual-channel memory and 89.6 GB/s bandwidth. Both use AMD Socket FP8 and have Gen 4 PCIe with 16 lanes (CPU only). The Ryzen AI 7 450 supports ECC memory, while the Ryzen AI 9 365 does not. Neither chip has an unlocked multiplier.
