AMD Ryzen AI 7 450G vs Intel Core Ultra 9 285H Comparison

The Verdict

The recorded data splits these two processors along clear workload lines. The AMD Ryzen AI 7 450G takes 4 of the 11 head-to-head benchmark wins, while the Intel Core Ultra 9 285H claims 7. The AMD part is the stronger integer and data-compression engine, with a 16.1% lead in integer math and a 19.9% lead in data compression. The Intel part dominates floating-point work, prime-number finding, physics simulation, and encryption, with margins ranging from 2.4% to 73.6%.

The average benchmark score tells a different story than the head-to-head wins. The AMD Ryzen AI 7 450G posts an average score of 63331, placing it in the 93rd percentile of all CPUs. The Intel Core Ultra 9 285H averages 38312, sitting in the 86th percentile. That gap reflects the benchmark mix: the AMD sample includes heavy data-compression and integer workloads where it excels, while the Intel sample includes Cinebench and Geekbench results that pull its average down relative to its PassMark wins.

For buyers, the data suggests the AMD part for compression-heavy, integer-heavy, and extended-instruction workloads, and the Intel part for encryption, physics, floating-point math, and prime-number sieving. The Intel part also edges ahead in single-thread performance by 2.4%, though that margin is small. The AMD part is a desktop AM5 socket part with an unlocked multiplier; the Intel part is a mobile BGA package with a locked multiplier.

Architecture Differences

The two chips come from different design philosophies. The AMD Ryzen AI 7 450G uses the Gorgon Point codename, belongs to the Ryzen AI 400 generation built on Zen 5 / Zen 5c cores, and is fabricated on a 4 nm TSMC process. It has 8 cores and 16 threads. The Intel Core Ultra 9 285H uses the Arrow Lake-H codename, belongs to the Core Ultra Series 2 generation, and is fabricated on a 3 nm TSMC process. It has 16 cores and 16 threads, meaning it uses a mix of performance and efficiency cores without hyperthreading on the performance cores.

Cache hierarchies differ substantially. The AMD part allocates 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of L3. The Intel part allocates 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3. That 3x L3 advantage for Intel shows in latency-sensitive workloads like the prime-number test, where Intel leads by 73.6%.

The process node difference is small but measurable: 4 nm for AMD versus 3 nm for Intel. Both use TSMC as the foundry. The AMD die size is 195 mm²; the Intel die size is not recorded. Both support DDR5 and LPDDR5X memory over dual-channel buses, but the Intel part has a higher memory bandwidth at 102.4 GB/s versus 89.6 GB/s for AMD. Both support ECC memory.

PCIe connectivity differs: the AMD part provides Gen 4 with 12 CPU lanes, while the Intel part provides Gen 5 with 8 CPU lanes. The AMD part has an unlocked multiplier, the Intel part does not. The integrated graphics also differ: AMD uses the Radeon 860M, Intel uses Arc Graphics 140T.

Head-to-Head Benchmarks

The largest AMD win comes in data compression, where the Ryzen AI 7 450G scores 402831 against the Intel part's 335859, a 19.9% advantage. Integer math also favors AMD: 99732 versus 85922, a 16.1% lead. Extended instructions favor AMD by 5.3%, with scores of 28223 and 26794. Random string sorting goes to AMD by 4.2%, at 42663 versus 40931.

The largest Intel win is in the find-prime-numbers test, where Intel scores 330 against AMD's 87, a 73.6% margin. Floating-point math favors Intel by 41.7%, with 109190 versus 63683. Physics simulation goes to Intel by 42.7%, at 2513 versus 1440. Data encryption favors Intel by 27.6%, at 26140 versus 18937. The multithread PassMark test goes to Intel by 11%, at 34171 versus 30422. Single-thread performance favors Intel by 2.4%, at 4415 versus 4309.

The Intel part also holds Cinebench and Geekbench scores in its database record. Its Cinebench R23 multicore score is 20781.5, with a single-core score of 2129.5. Geekbench multicore is 14743, single-core is 2178. These results are not directly comparable to the AMD PassMark scores, but they confirm the Intel part's strong multithreaded rendering performance.

The head-to-head record shows Intel winning 7 of 11 tests. However, the AMD wins are concentrated in areas that often matter for productivity: compression, integer math, and string sorting. The Intel wins are in compute-heavy areas like floating-point, physics, and encryption. The single-thread margin is narrow enough that neither chip has a decisive edge in everyday responsiveness.
