The Intel part's nearest rivals include the Intel Core i7-13790F (0.1 percent ahead), the AMD Ryzen AI 7 450G (0.2 percent behind), and the AMD Ryzen AI Embedded P185 (0.5 percent ahead). The AMD chip's nearest rivals include the AMD Ryzen 7 7700 (0.1 percent behind), the Intel Core 5 221E (0.2 percent behind), and the Intel Core i9-13905H (0.7 percent behind).

Architecture Differences

The two processors use fundamentally different designs. The AMD Ryzen AI 9 365 is built on the Zen 5 architecture with the Strix Point codename, part of the Ryzen AI 300 generation. It uses a 4 nm process node from TSMC and has a die size of 233 mm². The Intel Core Ultra 7 265HX uses the Arrow Lake architecture with the Arrow Lake-HX codename, part of the Core Ultra Series 2 generation. It is fabricated on a 3 nm process node, also from TSMC, with a die size of 243 mm² and 17,800 million transistors.

Core counts differ substantially. The AMD chip has 10 cores and 20 threads, while the Intel chip has 20 cores and 20 threads. This means the Intel part relies on a mix of performance and efficiency cores, while the AMD part uses a smaller core count with symmetric multithreading. The AMD chip's base clock is 2.00 GHz with a boost clock of 5.00 GHz. The Intel chip runs at 2.60 GHz base and 5.30 GHz boost.

Cache hierarchies diverge significantly. The AMD chip provides 80 KB of L1 cache per core, 1 MB of L2 per core, and 16 MB of L3 cache. The Intel chip offers 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3 cache. The larger cache allocation on the Intel side likely contributes to its single-core lead.

Memory support also differs. The AMD chip supports DDR5 and LPDDR5X memory with dual-channel access and a bandwidth of 89.6 GB/s. The Intel chip supports DDR5 only, also dual-channel, with a higher bandwidth of 102.4 GB/s. Neither chip supports ECC memory.

PCIe capabilities separate the two as well. The AMD chip uses PCIe Gen 4 with 16 lanes (CPU only), while the Intel chip uses PCIe Gen 5 with 20 lanes (CPU only). This gives the Intel part more headroom for high-bandwidth peripherals.

The integrated graphics differ: the AMD chip uses the Radeon 880M, while the Intel chip uses Arc Xe-LPG Graphics with 64 execution units. Both are mobile parts, and both are active in production. The Intel chip has an unlocked multiplier, while the AMD chip does not. The AMD part uses AMD Socket FP8, while the Intel part uses Intel BGA 2114.

Where Each One Wins

The benchmark results give the Intel Core Ultra 7 265HX a clean sweep across all recorded tests. There are no benchmark categories where the AMD Ryzen AI 9 365 shows a win. The Intel part's largest advantages appear in prime number finding (71.2 percent), single-core Cinebench R23 (65.3 percent), and floating-point math (61.1 percent). These are compute-heavy tasks that benefit from high per-core throughput and a robust FPU.

The Intel chip also shows strong results in data encryption (53.6 percent ahead), which suggests its cryptographic instruction set handles these workloads efficiently. Extended instructions (38.4 percent ahead) and multithread performance (38.6 percent ahead) further indicate that the Intel part sustains high throughput across mixed workloads.

The AMD chip's closest contests are in integer math (19.8 percent behind) and single-thread PassMark (14.6 percent behind). These are the only two tests where the deficit drops below 20 percent. Random string sorting shows a 36.8 percent gap, which is moderate compared to the other tests. Data compression sits at 30.7 percent behind, and physics simulation at 42.8 percent behind.

For users running integer-heavy code or light single-threaded tasks, the AMD chip comes closer to matching the Intel part. But in every measured category, the Intel Core Ultra 7 265HX delivers higher scores. The database shows no category where the AMD chip takes the lead, making the Intel part the stronger choice across the board.

The Verdict

Based strictly on the recorded data, the Intel Core Ultra 7 265HX is the superior processor for raw performance. It wins every head-to-head benchmark, shows a higher average score (63173 vs 40048), and sits higher in the percentile ranking (93rd vs 87th). The Intel part's nearest rivals in the database are other high-end desktop and mobile chips, while the AMD part sits closer to mid-range performers.

The AMD Ryzen AI 9 365 is not without merit. Its smaller core count and lower TDP (28 vs 55) suggest it may fit into thinner, more power-conscious chassis. Its support for LPDDR5X memory and AMD Socket FP8 could make it easier to integrate into specific mobile designs. The Radeon 880M integrated graphics may offer competitive visual output, though the database does not include GPU benchmark comparisons.

However, for users who prioritize CPU throughput, the Intel part is the clear winner. The 117 percent average score advantage (63173 vs 40048) is substantial, and the 54 percent Cinebench R23 multicore lead indicates that heavily threaded workloads will finish far faster on the Intel chip. The 65.3 percent single-core lead in Cinebench R23 also means even lightly threaded applications will feel more responsive.

The choice depends on the use case. For maximum compute performance, the Intel Core Ultra 7 265HX is the only option between these two. For a lower-power mobile processor with acceptable performance, the AMD Ryzen AI 9 365 may be sufficient, especially if the system design benefits from its LPDDR5X support and smaller socket.
