AMD Ryzen AI 7 PRO 450 vs Intel Core Ultra 7 265H Comparison

The Verdict

The Intel Core Ultra 7 265H is the clear performance leader in this comparison. It wins 14 of the 15 head-to-head benchmark tests recorded in the database, with the AMD Ryzen AI 7 PRO 450 taking only a single win. The average benchmark score tells the same story: the Intel part scores 41,621 versus 37,093 for the AMD chip, a margin that places the Core Ultra 7 265H in the 88th percentile of all CPUs while the Ryzen AI 7 PRO 450 sits in the 85th percentile.

The AMD Ryzen AI 7 PRO 450 is only competitive in one specific workload: integer math, where it edges out the Intel chip by 0.9%. For any other measured task, the Intel Core Ultra 7 265H delivers noticeably higher performance, with the largest gaps appearing in floating-point math, prime number finding, and data encryption. The verdict is straightforward: the Intel Core Ultra 7 265H is the stronger processor for essentially all compute-heavy mobile workloads, while the AMD part offers a narrower advantage in integer-heavy processing and a different platform feature set.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI 7 PRO 450 uses the Zen 5 architecture on a 4 nm TSMC process node, with the Gorgon Point codename and a die size of 195 mm². It is part of the Ryzen AI PRO 400 generation, which combines Zen 5 and Zen 5c cores. The chip has 8 cores and 16 threads, meaning it relies on simultaneous multithreading to reach its thread count.

The Intel Core Ultra 7 265H uses the Arrow Lake architecture on a 3 nm TSMC process node, with the Arrow Lake-H codename. It belongs to the Core Ultra Series 2 generation. Intel's approach differs markedly: the chip has 16 physical cores and 16 threads, meaning every core is a physical core with no multithreading. This gives Intel a 2-to-1 core count advantage while both parts offer the same thread count of 16.

Cache configurations diverge substantially. The AMD chip has 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of shared L3 cache. The Intel chip has 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3 cache. The Intel part therefore has more cache at every level, with its L3 being three times larger than AMD's.

The integrated graphics also differ. AMD uses the Radeon 860M, while Intel uses the Arc Graphics 140T. Both support DDR5 and LPDDR5X memory in a dual-channel configuration, but the Intel chip has a higher memory bandwidth rating: 102.4 GB/s versus 89.6 GB/s for AMD. Both support ECC memory and both are mobile-market processors with a 28 W TDP. The AMD part uses the AMD Socket FP8 with PCIe Gen 4 at 16 lanes (CPU only), while Intel uses the Intel BGA 2049 socket with PCIe Gen 5 at 8 lanes (CPU only). The AMD chip was released in January 2026, while the Intel chip was released in January 2025.

Head-to-Head Benchmarks

The benchmark data shows a consistent pattern of Intel dominance across nearly every test category. In Cinebench R23 multicore, the Intel Core Ultra 7 265H scores 19,940 against 16,054 for the AMD chip, a 19.5% advantage. The single-core result is closer but still favors Intel: 2,080 versus 2,010, a 3.4% gap. Cinebench R15 shows a larger single-core margin, with Intel at 307 versus 220, a 28.3% difference, and a 17.8% multicore lead at 2,989 versus 2,457.

The most dramatic gaps appear in PassMark's specialized math and encryption tests. In floating-point math, the Intel chip scores 109,123 against 52,971, a 51.5% advantage. The prime number finding test shows an even larger relative gap: Intel scores 335 versus 84, a 74.9% difference. Data encryption follows with Intel at 26,005 versus 14,925, a 42.6% lead. The physics test shows Intel ahead by 46.5%, scoring 2,497 versus 1,337.

Other PassMark tests continue the trend. Extended instructions favor Intel by 22.5%, with scores of 26,805 versus 20,778. Random string sorting goes to Intel at 40,742 versus 32,344, a 20.6% lead. Data compression favors Intel by 12.1%, with 334,711 versus 294,298. The multithread test shows Intel at 34,027 versus 24,779, a 27.2% advantage. Single-thread performance favors Intel by 8.7%, with 4,334 versus 3,955.

The single AMD win comes in integer math, where the Ryzen AI 7 PRO 450 scores 86,227 against 85,479, a 0.9% margin. This is a narrow victory and does not offset the substantial losses elsewhere. The overall benchmark average confirms the Intel advantage: 41,621 versus 37,093, a difference of roughly 12%.

Specification Differences
