AMD Ryzen AI 7 450 vs Intel Core Ultra 7 366H Comparison

AMD Ryzen AI 7 450 and Intel Core Ultra 7 366H are both active mobile processors aimed at thin-and-light laptops, but the benchmark data shows a clear performance hierarchy. The Intel part wins 14 of the 15 recorded head-to-head comparisons, often by substantial margins, while the AMD chip secures a single victory in integer math. The average benchmark scores confirm the gap: 41,263 for the Intel versus 39,485 for the AMD, a difference of about 4.5%. Both sit at the 87th percentile of all CPUs in the database, meaning they land in the same overall performance tier, but the distribution of wins within that tier heavily favors Intel.

Head-to-Head Benchmarks

The most decisive Intel victories come in single-core and floating-point workloads. In Cinebench R23 single-core, the Core Ultra 7 366H scores 4,020 against the Ryzen AI 7 450's 2,038, a delta of 49.3% in Intel's favor. The R15 single-core result is even more lopsided: 405 versus 215, a 46.9% lead. These are not marginal wins; the Intel core design delivers roughly double the single-threaded performance in these rendering tests. The same pattern appears in PassMark floating-point math, where Intel scores 103,615 versus 54,447, a 47.5% advantage, and in PassMark physics, where Intel leads 2,880 to 1,578, a 45.2% gap.

Multi-core rendering also favors Intel, though by a smaller margin than single-core. In Cinebench R23 multi-core, the Intel part scores 28,477 against 18,316 for the AMD, a 35.7% lead. The R15 multi-core test shows Intel ahead at 2,870 versus 2,713, a 5.5% margin. The PassMark multi-thread score follows the same direction: 33,429 for Intel versus 26,350 for AMD, a 21.2% advantage. Data-heavy workloads show narrower Intel wins. PassMark data compression is close at 327,455 versus 315,906, a 3.5% lead, and random string sorting gives Intel 39,814 against 35,648, a 10.5% edge. Data encryption is a larger gap at 25,845 versus 16,247, a 37.1% lead for Intel.

The AMD Ryzen AI 7 450 takes its sole win in PassMark integer math, scoring 88,531 against Intel's 83,695, a 5.8% advantage. This is a notable result because it shows the AMD core is not universally slower; in pure integer arithmetic it outperforms the Intel chip. The extended instructions test also favors Intel, but at a more modest 16.7% delta: 26,901 versus 22,400. The find prime numbers test is the most extreme Intel win, with 326 versus 89, a 72.7% gap that suggests a substantial difference in the handling of that specific workload. Overall, the benchmark data shows a processor that wins on nearly every axis, with the AMD chip's single victory confined to a narrow compute scenario.

Architecture Differences

The two processors are built on fundamentally different architectures. The AMD Ryzen AI 7 450 uses the Zen 5 architecture with the Gorgon Point codename, part of the Ryzen AI 400 generation that combines Zen 5 and Zen 5c cores. It has 8 cores and 16 threads, fabricated on a 4 nm process at TSMC with a die size of 195 mm². The Intel Core Ultra 7 366H uses the Panther Lake architecture with the same Panther Lake codename, part of the Ultra 7 generation for Panther Lake-H. It has 16 cores and 16 threads, meaning it does not use simultaneous multithreading; each thread maps to a physical core. Intel fabricates this chip on a 3 nm process at its own foundry, and no die size is recorded in the database.

Cache configurations differ substantially. The AMD chip has 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of L3 cache. The Intel chip has 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3 cache. The larger L1 and L2 allocations per core on Intel likely contribute to its single-thread performance edge, while the bigger shared L3 pool helps with multi-core data sharing. Both support DDR5 and LPDDR5X memory over a dual-channel bus, but the memory bandwidth figures are different: 89.6 GB/s for AMD versus 115.2 GB/s for Intel. The Intel part also uses PCIe Gen 5 with 12 CPU lanes, while the AMD part uses PCIe Gen 4 with 16 CPU lanes.

The base clocks are identical at 2.00 GHz, but boost clocks differ: the AMD chip reaches 5.10 GHz, while the Intel chip tops out at 4.80 GHz. Despite the higher AMD boost clock, Intel still wins the single-thread benchmarks, indicating that IPC (instructions per clock) differences favor the Intel architecture. The TDP ratings are close at 28 W for AMD and 25 W for Intel, both suited for mobile designs. The integrated graphics differ as well: AMD uses the Radeon 860M, while Intel uses Xe3 Graphics. Neither GPU has recorded benchmark scores in the database, so the comparison rests on CPU workloads only. The AMD chip supports ECC memory, while the Intel chip does not. Both are socketed differently: AMD Socket FP8 for the AMD part, Intel BGA 2540 for the Intel part.

The Verdict

The data points to a clear recommendation for the Intel Core Ultra 7 366H in nearly all compute scenarios. It leads in 14 of 15 benchmarks, including every Cinebench test, all PassMark math workloads except integer math, and all data processing tests. The margins range from a close 3.5% in data compression and single-thread scores to a dominant 72.7% in find prime numbers. For users running rendering, physics simulations, encryption, or floating-point-heavy code, the Intel chip is the stronger choice based on the recorded results. Its higher average benchmark score of 41,263 versus 39,485 reinforces this, even though both processors share the same 87th percentile ranking.

The AMD Ryzen AI 7 450 is the better option only for workloads that stress integer math, where it holds a 5.8% lead. It also offers ECC memory support, which the Intel part lacks, a feature that matters for error-sensitive computing tasks. The AMD chip has a higher boost clock at 5.10 GHz versus 4.80 GHz, but the benchmark results show this does not translate into a real-world advantage in single-threaded tests. For a mobile laptop processor where the majority of tasks are mixed integer and floating-point work, the Intel Core Ultra 7 366H is the more capable part according to the data.

Where Each One Wins

The Intel Core Ultra 7 366H wins in rendering, both single and multi-core. Cinebench R23 single-core shows a 49.3% lead, and R23 multi-core shows a 35.7% lead. These are the tests most representative of 3D modeling, video encoding, and general productivity where single-thread speed matters. The Intel chip also wins in physics and floating-point math, with 45.2% and 47.5% gaps respectively, making it the pick for simulation and scientific workloads. Data encryption favors Intel by 37.1%, and extended instructions by 16.7%, covering security and specialized compute tasks. The find prime numbers test, with its 72.7% Intel lead, points to a major advantage in prime-finding or similar algorithmic workloads.

The AMD Ryzen AI 7 450 wins only in integer math, with a 5.8% edge. This covers arithmetic that does not use fractional numbers, common in database lookups, file indexing, and certain financial calculations. The AMD chip also provides ECC memory support, which is a hardware feature rather than a benchmark win, but it matters for users who need data integrity in memory. For anyone running mixed workloads or standard laptop tasks, the Intel part dominates. For a niche use case focused purely on integer operations, the AMD chip has a small but real advantage. The data does not support any other scenario where the AMD processor comes out ahead.
