Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen AI 5 PRO 440 is built on the Zen 5 architecture with the Gorgon Point codename, part of the Ryzen AI PRO 400 generation that mixes Zen 5 and Zen 5c cores. It uses a 4 nm process node at TSMC with a die size of 195 mm². The Intel Core Ultra 9 285H uses the Arrow Lake-H design, part of the Core Ultra Series 2, and moves to a smaller 3 nm process node, also fabricated by TSMC.

Core counts differ substantially. The AMD part has 6 cores and 12 threads, relying on simultaneous multithreading to reach its thread count. The Intel part has 16 cores and 16 threads, which means it does not use hyper-threading; each core provides one thread. This raw core advantage gives Intel a structural edge in heavily parallel workloads, although the AMD chip’s efficiency-oriented design targets lower power draw.

Cache hierarchies are not comparable in size. AMD allocates 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of L3. Intel allocates 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3. The larger per-core L1 and L2 on the Intel chip, combined with the tripled L3, suggests a design that feeds more data to each execution unit.

Memory support is similar on paper: both accept DDR5 and LPDDR5X over a dual-channel bus. However, Intel’s memory bandwidth is recorded at 102.4 GB/s, while AMD’s is 89.6 GB/s. Both support ECC memory. PCIe connectivity differs: AMD provides Gen 4 with 16 CPU lanes, while Intel provides Gen 5 with 8 CPU lanes. The integrated graphics also differ, with AMD using Radeon 840M and Intel using Arc Graphics 140T.

The Intel part has a higher base clock of 2.90 GHz and a boost clock of 5.40 GHz, against AMD’s 2.00 GHz base and 4.80 GHz boost. The TDP rating also splits them: 45W for Intel versus 28W for AMD. The AMD part uses the AMD Socket FP8, while Intel uses the BGA 2049 package.

Head-to-Head Benchmarks

The recorded head-to-head data shows a clean sweep for the Intel Core Ultra 9 285H across all eleven PassMark tests. No test in the comparison favors the AMD Ryzen AI 5 PRO 440.

The largest margin appears in the prime number search test. Intel scores 330 against AMD’s 77, a 76.7% deficit for the AMD chip. This test often stresses integer throughput and branch prediction, and the 16-core Intel part dominates.

Floating-point math shows a similarly large gap. Intel scores 109190 versus AMD’s 42934, a 60.7% difference. The physics test, which tends to simulate rigid body or particle workloads, gives Intel 2513 against AMD’s 1119, a 55.5% lead. Data encryption also favors Intel heavily: 26140 versus 12418, a 52.5% advantage.

The multi-thread test is 38.4% in favor of Intel, with scores of 34171 and 21054. Random string sorting follows with Intel at 40931 and AMD at 27252, a 33.4% gap. Extended instructions show Intel ahead by 31.1%, scoring 26794 versus 18456.

The smallest margins are still decisive. Integer math gives Intel 85922 versus AMD’s 65991, a 23.2% lead. Data compression shows Intel at 335859 against AMD’s 256420, a 23.7% gap. Single-thread performance, the closest test, has Intel at 4415 and AMD at 3785, a 14.3% difference.

The average benchmark score in the database places the AMD part at 41208, while the Intel part sits at 38312. That seems counterintuitive given the head-to-head sweep, but the two chips occupy different positions in the percentile rankings: AMD is at the 87th percentile of all CPUs, while Intel is at the 86th. The nearest rivals for AMD include the Intel Core Ultra 7 356H at 41215 and the AMD Ryzen 9 5900X at 41376, while Intel’s nearest rivals include the Intel Core 9 270H at 38335 and the Intel Core i5-13600HX at 38261.

The Verdict

The benchmark data indicates that the Intel Core Ultra 9 285H is the stronger processor in every measured PassMark workload. The 16-core design with 24 MB of L3 cache and higher clock speeds delivers leads ranging from 14.3% in single-thread to 76.7% in prime number calculation. For workloads that scale across cores, such as rendering, encryption, or floating-point simulation, Intel’s advantage is substantial.

The AMD Ryzen AI 5 PRO 440 does offer a lower TDP of 28W versus Intel’s 45W, which suggests it may fit into thinner or more power-conscious mobile designs. Its average benchmark score is actually higher than Intel’s in the database (41208 versus 38312), and it ranks one percentile higher (87th versus 86th). This discrepancy likely reflects different benchmark suites or weighting in the average score calculation, but the direct head-to-head PassMark results are unambiguous.

For users who prioritize raw compute throughput, the data points to the Intel part. For users who prioritize power efficiency and still need decent multi-threading, the AMD part shows a more favorable performance-per-watt profile, though exact efficiency ratios are not in the database.

Where Each One Wins

The Intel Core Ultra 9 285H wins in all recorded benchmark categories. Its largest victories come in prime number finding (76.7% ahead), floating-point math (60.7% ahead), and physics simulation (55.5% ahead). These results indicate a clear advantage in scientific computing, financial modeling, and any workload that relies heavily on floating-point arithmetic or complex integer loops. The 16 physical cores and 24 MB of shared L3 cache provide ample resources for parallel execution.

The AMD Ryzen AI 5 PRO 440 does not win any head-to-head benchmark, but it holds advantages in non-performance dimensions. Its 28W TDP is 17W lower than Intel’s, which could translate into longer battery life in mobile systems, though the database does not record battery tests. Its 4 nm process node, while larger than Intel’s 3 nm node, still represents a modern manufacturing technology. The AMD chip also uses PCIe Gen 4 with 16 lanes, which may offer more total bandwidth for multiple devices than Intel’s Gen 5 with 8 lanes, depending on device count.

The average benchmark score field tells a different story. AMD’s average of 41208 edges out Intel’s 38312, and AMD’s percentile rank of 87 exceeds Intel’s 86. This suggests that in the broader database context, the AMD chip performs comparably to or slightly better than the Intel chip when averaged across a wide range of tests beyond the PassMark suite included in the head-to-head. The Intel part’s closest rival, the Intel Core 9 270H, sits at 38335, nearly identical, while AMD’s closest rival, the Intel Core Ultra 7 356H, sits at 41215, also nearly identical.

For workloads that fit within the PassMark head-to-head set, the Intel Core Ultra 9 285H is the clear choice. For workloads that align more with the average benchmark score distribution, the AMD Ryzen AI 5 PRO 440 appears at least competitive. The data does not support a single universal winner; it supports a split based on workload type and power constraints.
