Where Each One Wins

The AMD Ryzen AI 7 450 takes the majority of benchmark victories, winning 8 out of 15 head-to-head tests. Its wins are concentrated in workloads that scale with thread count and raw compute throughput. This includes all multi-core Cinebench tests, PassMark multithread, integer math, data compression, data encryption, extended instructions, and random string sorting. The largest advantage appears in integer math, where the AMD part scores 88,531 versus 41,558 for the Intel chip, a 113% difference. Data compression also shows a massive gap, with the Ryzen AI 7 450 scoring 315,906 compared to 187,050, a 68.9% delta. These results indicate that the AMD processor is the better choice for content creation, code compilation, and any workload that can use its 16 threads.

The Intel Core Ultra 7 266V wins 7 tests, but its victories are narrower and concentrated in single-threaded performance and specific math operations. It wins Cinebench R15 and R23 single-core tests, PassMark single-thread, floating point math, physics, and find prime numbers. The single-thread wins are consistent, with margins ranging from 1.1% to 12.7%. The most notable Intel win is in find prime numbers, where it scores 191 versus 89 for the AMD, a 53.4% advantage. This suggests the Intel processor has a strong integer execution pipeline for certain algorithms, but its overall thread count limits its appeal for general multi-threaded work. The physics test is a narrow win for Intel, 1,608 versus 1,578, a 1.9% margin, indicating near parity in that specific simulation workload.

The use-case split is clear. The AMD Ryzen AI 7 450 is the multi-threaded workhorse, delivering 35.4% higher PassMark multithread scores and 62.7% higher Cinebench R15 multi-core scores. The Intel Core Ultra 7 266V is the single-thread specialist, but its advantages are smaller in percentage terms, and it cannot match the AMD processor in sustained all-core workloads. For users running parallel tasks, the database favors AMD. For lightly threaded applications where single-core speed is the bottleneck, Intel holds a measurable, but smaller, edge.

Architecture Differences

The two processors come from different architectural generations and process nodes. The AMD Ryzen AI 7 450 uses the Zen 5 architecture, specifically the Gorgon Point codename, built on TSMC's 4 nm process. It has 8 cores and 16 threads, with a base clock of 2.00 GHz and a boost clock of 5.10 GHz. The Intel Core Ultra 7 266V uses the Lunar Lake architecture, also built on TSMC but at 3 nm, with a base clock of 2.20 GHz and a boost clock of 5.00 GHz. The Intel part has 8 cores but only 8 threads, meaning no simultaneous multithreading, which directly explains its lower multi-threaded scores.

Cache configurations differ significantly. The AMD processor has 80 KB of L1 cache per core, 1 MB of L2 per core, and 8 MB of shared L3 cache. The Intel processor has 192 KB of L1 per core, 2.5 MB of L2 per core, and 12 MB of shared L3 cache. The larger L2 and L3 caches on the Intel part may contribute to its single-threaded efficiency, particularly in workloads that fit within cache. However, the AMD part compensates with more threads and higher boost clocks.

Memory support also diverges. The AMD Ryzen AI 7 450 supports DDR5 and LPDDR5X over a dual-channel bus, with 89.6 GB/s of bandwidth. The Intel Core Ultra 7 266V supports LPDDR5X (depending on motherboard) over a dual-channel bus, with 136.5 GB/s of bandwidth. The Intel chip has a 52% memory bandwidth advantage, which may help in memory-intensive single-threaded tasks. The AMD processor supports ECC memory, while the Intel part does not. PCIe support is another differentiator: AMD offers Gen 4 with 16 lanes (CPU only), while Intel offers Gen 5 with 4 lanes (CPU only). This suggests the AMD platform can support more expandability, while Intel prioritizes the newer standard for fewer devices.

The integrated graphics also differ: AMD uses the Radeon 860M, while Intel uses the Arc 140V. Both are mobile parts, but the database does not include graphics benchmarks, so the comparison is limited to CPU performance. The TDP ratings show a 28 W envelope for AMD versus 17 W for Intel, indicating the AMD part is designed for higher performance at the cost of power, while the Intel part targets efficiency. The Intel processor released on 2024-09-23, while the AMD processor has a release date of 2026-01-04, putting them in different product cycles.

Head-to-Head Benchmarks

The Cinebench tests reveal the core split. In Cinebench R15 multi-core, the AMD Ryzen AI 7 450 scores 2,713 versus 1,667 for the Intel, a 62.7% delta. This is the largest multi-core margin in the suite. In Cinebench R23 multi-core, the gap narrows to 10.7%, with AMD at 18,316 and Intel at 16,544. The single-core results flip: Cinebench R15 single-core shows Intel at 235 versus AMD at 215, an 8.5% advantage. Cinebench R23 single-core shows Intel at 2,335 versus 2,038, a 12.7% advantage. The multi-core margins vary widely across test versions, but the direction is consistent.

PassMark results show a similar pattern. In integer math, the AMD processor scores 88,531 against 41,558, a 113% delta, which is the largest single advantage recorded. Data compression shows AMD at 315,906 versus 187,050, a 68.9% delta. Extended instructions show AMD at 22,400 versus 15,928, a 40.6% delta.

These figures place the AMD part in a higher performance class overall.

The Verdict

The data indicates two distinct profiles. The AMD Ryzen AI 7 450 is the superior multi-threaded processor, with wins in 8 of 15 benchmarks and massive margins in integer math, data compression, and multithread. Its 16 threads and higher boost clock of 5.10 GHz give it a substantial lead in any workload that can parallelize. The 62.7% advantage in Cinebench R15 multi-core and the 113% advantage in integer math are not marginal differences; they represent a generational gap in throughput. The 87th percentile placement confirms that this processor competes with higher-end desktop parts.

The Intel Core Ultra 7 266V is the efficiency-focused single-thread contender. Its wins in Cinebench single-core and find prime numbers show that it has a fast core, but the lack of multithreading holds it back. The 12.7% advantage in Cinebench R23 single-core is real, but it does not offset the 10.7% deficit in multi-core for the same test. The 76th percentile placement and an average score of 23,297 put it in a lower tier, closer to older Ryzen 7 5800H parts than to the AMD Ryzen AI 7 450.

For users who prioritize multi-core performance, the AMD Ryzen AI 7 450 is the clear choice based on recorded data. For users who need the best single-thread speed and are willing to sacrifice multi-core capability, the Intel Core Ultra 7 266V offers a narrower advantage. The AMD processor also supports ECC memory and has more PCIe lanes, while the Intel processor offers higher memory bandwidth and a newer PCIe standard. The verdict depends on workload, but the benchmark evidence strongly favors AMD for general compute tasks.
