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

The AMD Ryzen AI 7 450G and Intel Core Ultra 7 366H represent two distinct philosophies in processor design, with the former aimed at desktop systems and the latter at mobile platforms. The recorded data shows that the AMD part wins 6 of the 11 head-to-head benchmarks, while the Intel part wins 5, but the nature of those victories reveals a deeper story about workload suitability. The AMD Ryzen AI 7 450G achieves a 93rd percentile ranking across all CPUs, while the Intel Core Ultra 7 366H sits at the 87th percentile. The average benchmark score for the AMD is 63331, compared to 41263 for the Intel, a substantial gap that is heavily influenced by the AMD chip’s dominance in data compression tests. However, the Intel processor counters with decisive wins in floating-point math, physics, and prime number finding, indicating that the choice between these two depends entirely on the intended application.

The Verdict

The benchmark results indicate that the AMD Ryzen AI 7 450G is the stronger overall performer for general desktop productivity, particularly in workloads involving data compression and integer math. Its average benchmark score of 63331 places it 53.5% higher than the Intel Core Ultra 7 366H’s 41263, and its percentile ranking of 93 versus 87 confirms its broader appeal. The AMD chip wins the crucial single-thread test with a score of 4309 against 4043, a 6.6% advantage, which translates to faster responsiveness in everyday tasks and lightly threaded software. For users building a desktop system with an AM5 socket, the data clearly favors the AMD part, especially given its higher boost clock of 5.10 GHz compared to 4.80 GHz and its unlocked multiplier, which allows for overclocking.

The Intel Core Ultra 7 366H, despite its lower average score, is not without merit. Its 16 cores and 16 threads match the thread count of the AMD, but its design prioritizes specific computational strengths. The Intel chip wins the multithread benchmark with 33429 against 30422, a 9% lead, and delivers a massive 62.7% advantage in floating-point math (103615 versus 63683). This makes it the preferable choice for mobile users who need to run scientific simulations, 3D rendering, or any workload that relies heavily on floating-point operations. The Intel processor also wins in physics calculations, scoring 2880 versus 1440, a 50% lead, and in prime number finding, where it scores 326 against 87. These results suggest that the Intel chip is engineered for sustained computational throughput in specific mathematical domains, which can be critical for professional applications on laptops.

It offers 16 cores and 16 threads, with a base clock of 2.00 GHz and a boost clock of 4.80 GHz. The cache configuration is far larger: 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3 cache. The socket is Intel BGA 2540, designed for mobile use, and the TDP is just 25 watts. Memory support is dual-channel DDR5 and LPDDR5X with a higher bandwidth of 115.2 GB/s, but without ECC support. The integrated graphics are Intel Xe3 Graphics, and the PCIe interface is Gen 5 with 12 lanes. The Intel chip does not have an unlocked multiplier, aligning with its mobile market segment, while the AMD part is unlocked for overclocking.
