AMD Ryzen AI 5 440G vs Intel Core Ultra 7 366H Comparison

The Verdict

The recorded benchmark data delivers a clear verdict: the Intel Core Ultra 7 366H is the dominant processor in this comparison, winning 9 of the 11 shared head-to-head tests. The AMD Ryzen AI 5 440G claims only 2 wins, both in single-thread performance, and by a razor-thin margin. The Intel part leads by double-digit percentages in most multi-threaded workloads, with its largest advantages exceeding 70%. The data indicates that the Intel Core Ultra 7 366H is the stronger choice for compute-heavy tasks, while the AMD Ryzen AI 5 440G is preferable only when absolute peak single-core speed is the priority, and even then the difference is minimal.

The Intel Core Ultra 7 366H achieves a multithread score of 33429 against 23487 for the AMD part, a 29.7% advantage. The floating-point math result is even more lopsided: 103615 versus 45711, a 55.9% lead. The AMD Ryzen AI 5 440G does edge ahead in single-thread performance, scoring 4060 versus 4043, a 0.4% difference that is effectively negligible for real-world applications. The database's overall average benchmark scores reflect the same hierarchy: the AMD part averages 46187 across its suite, while the Intel part averages 41263. This apparent contradiction is explained by the different benchmark sets each processor was tested with, so the head-to-head results are the more reliable comparison for these two specific chips.

In terms of market positioning, the AMD Ryzen AI 5 440G sits at the 89th percentile of all CPUs in the database, while the Intel Core Ultra 7 366H sits at the 87th percentile. The AMD part's nearest rivals include the Intel Core i9-13900HX, Intel Core Ultra 5 235, AMD Ryzen AI 9 HX 375, and AMD EPYC 4364P, all within 0.5% of its average score. The Intel part's nearest rivals are the Intel Core Ultra 7 356H, AMD Ryzen AI 5 PRO 440, AMD Ryzen 9 5900X, and Intel Core Ultra X7 358H, with deltas ranging from -0.3% to 0.7%. These figures confirm that both processors are competitive within their respective peer groups, but the Intel part's peer group on average scores lower than the AMD part's peer group.

Architecture Differences

The two processors come from different manufacturers and use different design philosophies. The AMD Ryzen AI 5 440G is built on the Gorgon Point codename, part of the Ryzen AI 400 generation that uses a hybrid of Zen 5 and Zen 5c cores. It is manufactured on a 4 nm process at TSMC, with a die size of 195 mm². The Intel Core Ultra 7 366H, by contrast, uses the Panther Lake architecture, part of the Core Ultra Series 3 generation at the Panther Lake-H tier. It is manufactured on a 3 nm process at Intel's own foundry. The die size for the Intel part is not recorded in the database.

Core counts differ substantially. The AMD part has 6 cores and 12 threads, while the Intel part has 16 cores and 16 threads. The Intel part does not use simultaneous multithreading, so its thread count equals its core count. The AMD part uses SMT to double its thread count. Both processors run at identical base clocks of 2.00 GHz and identical boost clocks of 4.80 GHz, according to the recorded specifications.

Cache hierarchies also differ. The AMD Ryzen AI 5 440G has 80 KB of L1 cache per core, 1 MB of L2 cache per core, and 8 MB of L3 cache. The Intel Core Ultra 7 366H has 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 18 MB of shared L3 cache. The Intel part therefore offers more cache at every level, which aligns with its larger core count.

Memory support differs as well. The AMD part supports DDR5 memory on a dual-channel bus with a recorded bandwidth of 89.6 GB/s. The Intel part supports both DDR5 and LPDDR5X memory on a dual-channel bus with a recorded bandwidth of 115.2 GB/s. The Intel part also supports ECC memory, while the AMD part does not, according to the database. PCIe connectivity differs: the AMD part uses Gen 4 with 12 lanes (CPU only), while the Intel part uses Gen 5 with 12 lanes (CPU only).

The integrated graphics differ. The AMD Ryzen AI 5 440G uses the Radeon 840M, while the Intel Core Ultra 7 366H uses Intel Xe3 Graphics. The database does not record benchmark scores for either integrated GPU, so no performance comparison can be made from the recorded data.

The AMD part is classified as a desktop processor with an AMD Socket AM5, has an unlocked multiplier, and has a TDP of 65. The Intel part is classified as a mobile processor with an Intel BGA 2540 socket, has a locked multiplier, and has a TDP of 25. The AMD part was released on 2026-02-28, while the Intel part was released on 2026-01-04. Neither part has a recorded launch MSRP in the database.

Where Each One Wins

The Intel Core Ultra 7 366H wins across nearly every measured workload category. Its largest advantages appear in prime number finding, where it scores 326 against 90 for the AMD part, a 72.4% lead. Floating-point math shows a 55.9% lead for Intel (103615 versus 45711), and physics simulation shows a 53.9% lead (2880 versus 1329). Data encryption is another strong Intel category, with a 47.4% lead (25845 versus 13585). Multithread performance favors Intel by 29.7% (33429 versus 23487), extended instructions by 23.2% (26901 versus 20648), random string sorting by 21.9% (39814 versus 31106), integer math by 14.9% (83695 versus 71251), and data compression by 10.6% (327455 versus 292735).

The AMD Ryzen AI 5 440G wins only in single-thread performance, scoring 4060 versus 4043 for the Intel part, a 0.4% advantage. This appears in both the passmark_single_thread and passmark_singlethread tests, which are duplicate measurements of the same workload. The margin is small enough that it falls within typical run-to-run variation, but the recorded data does list the AMD part as the winner in both entries.

The pattern is clear: the Intel part dominates in all multi-threaded and math-heavy workloads, while the AMD part holds a marginal edge in single-thread speed. For users running heavily parallel workloads such as rendering, physics simulation, or data encryption, the Intel part is the stronger option by a wide margin. For workloads that depend primarily on single-core speed, the two parts are effectively tied, with the AMD part holding a negligible lead.

Head-to-Head Benchmarks

The head-to-head results are unambiguous. The Intel Core Ultra 7 366H wins 9 of 11 tests, and its wins are typically large. The prime number finding test shows the biggest gap: Intel scores 326, AMD scores 90, a 72.4% difference. This is a workload where the Intel part's core count advantage is fully expressed. Floating-point math is nearly as lopsided, with Intel at 103615 and AMD at 45711, a 55.9% lead. Physics simulation follows the same trend, with Intel at 2880 and AMD at 1329, a 53.9% lead.

Data encryption shows Intel at 25845 versus AMD at 13585, a 47.4% lead. Multithread performance gives Intel 33429 versus AMD 23487, a 29.7% lead. Extended instructions give Intel 26901 versus AMD 20648, a 23.2% lead. Random string sorting gives Intel 39814 versus AMD 31106, a 21.9% lead. Integer math gives Intel 83695 versus AMD 71251, a 14.9% lead. Data compression gives Intel 327455 versus AMD 292735, a 10.6% lead. Every one of these categories favors the Intel part, and most by margins that would be clearly visible in real applications.

The only two tests won by the AMD part are the single-thread tests, which are duplicate measurements. The AMD part scores 4060 in both, while the Intel part scores 4043 in both. The 0.4% difference is the smallest margin in the entire dataset. It is notably the AMD part's advantage in this category is far smaller than the Intel part's advantages in any of its winning categories. The Intel part's smallest win is 10.6% in data compression, while the AMD part's only win is 0.4% in single-thread performance.

The overall average benchmark scores from the database's separate suites are not directly comparable because the two processors were tested with different benchmark sets. The AMD part has an average score of 46187, while the Intel part has an average score of 41263. However, the head-to-head tests use identical workloads for both parts, making them the authoritative comparison. The Intel part's wins are consistent across all multi-threaded categories, and the AMD part's single-thread win is marginal.
