The Intel Core Ultra 9 285 is the choice for any workload that prioritizes raw compute performance. The data shows it is consistently faster across single-threaded, multi-threaded, and specialized instruction tests. The AMD Ryzen AI 9 HX PRO 370, by contrast, is a mobile processor with a 28 TDP, designed for a different class of system. The Intel part is a desktop processor with a 65 TDP. The AMD chip offers a smaller physical footprint and lower power envelope, but the recorded benchmarks show no scenario where it outperforms the Intel part.

For users building a desktop system where performance is the sole criterion, the Intel Core Ultra 9 285 is the clear pick. For users requiring a mobile processor with integrated graphics and a low power draw, the AMD Ryzen AI 9 HX PRO 370 is the appropriate selection, but the performance trade-off is substantial and universal across all measured tests.

Where Each One Wins

The Intel Core Ultra 9 285 wins in every single recorded benchmark category. There is no test in the database where the AMD Ryzen AI 9 HX PRO 370 takes the lead. This includes Cinebench R15 and R23 multi-core and single-core tests, all PassMark tests (data compression, encryption, extended instructions, prime numbers, floating point math, integer math, multithread, physics, random string sorting, and single thread).

The AMD chip's role is defined by its market segment, not its benchmark wins. It is a mobile processor on AMD Socket FP8, while the Intel part is a desktop processor on Intel Socket 1851. The AMD processor uses a 28 TDP, the Intel part uses a 65 TDP. The database shows the AMD chip is the only one of the two with a dual-channel memory bus supporting both DDR5 and LPDDR5X, making it suited for compact mobile designs. The Intel part uses DDR5 only.

No workload category favors the AMD processor. Even in the closest comparison, PassMark single-thread, the Intel Core Ultra 9 285 scores 4881 against 4003 for the AMD chip, an 18% advantage. The largest single-thread gap appears in Cinebench R23 single-core, where the Intel part scores 6909 versus 1992, a 71.2% difference.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen AI 9 HX PRO 370 uses the Zen 5 architecture, codenamed Strix Point, built on a 4 nm process at TSMC. The Intel Core Ultra 9 285 uses the Arrow Lake architecture, codenamed Arrow Lake-S, built on a 3 nm process at TSMC. The Intel part is listed in the Core Ultra Series 2 generation, while the AMD part belongs to the Ryzen AI PRO 300 generation with a Zen 5 / Zen 5c hybrid core arrangement.

Core configuration differs sharply. The AMD chip has 12 cores and 24 threads. The Intel chip has 24 cores and 24 threads, meaning it does not use simultaneous multithreading. The AMD chip uses a per-core L1 cache of 80 KB and per-core L2 cache of 1 MB, with a 16 MB L3 cache. The Intel chip uses a per-core L1 cache of 192 KB and per-core L2 cache of 3 MB, with a 36 MB shared L3 cache. The Intel part has a larger die at 243 mm² versus 233 mm² for the AMD part, and the Intel part lists 17,800 million transistors while the AMD part does not list a transistor count.

Clock speeds differ as well. The AMD chip has a base clock of 2.00 GHz and a boost clock of 5.10 GHz. The Intel chip has a base clock of 2.50 GHz and a boost clock of 5.60 GHz. The Intel part also carries a higher memory bandwidth rating of 102.4 GB/s versus 89.6 GB/s for the AMD part. PCIe support differs: the AMD chip uses Gen 4 with 16 lanes, while the Intel chip uses Gen 5 with 20 lanes.

Integrated graphics differ. The AMD chip uses the Radeon 890M, while the Intel chip uses the Arc Xe-LPG Graphics 64EU. Both support ECC memory, and neither has an unlocked multiplier.
