AMD Ryzen AI 9 365 vs Intel Core Ultra 9 285 Comparison

Head-to-Head Benchmarks

The recorded data shows a dominant performance profile for the Intel Core Ultra 9 285, winning all 15 head-to-head benchmark comparisons against the AMD Ryzen AI 9 365. The Intel part leads by margins ranging from 21.3% to 74.5%, with the smallest advantage appearing in single-threaded workloads and the largest in prime number finding.

The single-core comparison is telling. In Cinebench R23 single-core, Intel scores 6909 against AMD's 1992, a 71.2% deficit for the Ryzen AI 9 365. The PassMark single-thread test tells a different story in magnitude: Intel scores 4881 versus 3841, a narrower 21.3% gap. This suggests the AMD Zen 5 architecture is comparatively stronger in single-threaded integer work than in the Cinebench rendering workload, though it still trails in both.

Multi-core performance shows an even wider separation. Cinebench R23 multi-core gives Intel 48945 points against AMD's 18698, a 61.8% deficit. The Cinebench R15 multi-core result repeats the pattern: 4933 for Intel versus 2842 for AMD, a 42.4% gap. The PassMark multithread score shows Intel at 56602 versus 29467, a 47.9% deficit. These numbers align with the core count disparity: Intel fields 24 cores against AMD's 10, though the AMD part supports 20 threads versus Intel's 24 threads.

The most lopsided result in the entire comparison is PassMark find prime numbers. Intel scores 459, AMD scores 117, a 74.5% deficit. This workload rewards the Intel architecture heavily, likely reflecting the combination of higher boost clock and larger cache allocation. Floating point math also favors Intel decisively: 194988 versus 62802, a 67.8% deficit for AMD. Data encryption shows Intel at 46949 against AMD's 18297, a 61% gap, while data compression gives Intel 602121 versus 354510, a 41.1% gap.

The extended instructions test gives Intel 45357 against 25113, a 44.6% deficit. Integer math is the closest multi-threaded comparison at 38.2% (164869 versus 101831). Random string sorting shows Intel at 73651 versus 39447, a 46.4% gap. Physics simulation gives Intel 3598 versus 1704, a 52.6% deficit. Even the Cinebench R15 single-core result, which is the oldest test in the set, shows Intel ahead at 696 versus 303, a 56.5% gap.

The average benchmark score in the database confirms the overall positioning. Intel's average is 75488 across its recorded benchmarks, while AMD's average is 40048. Intel sits at the 95th percentile of all CPUs in the database, AMD at the 87th percentile. Intel's nearest rivals include AMD EPYC 8224P at 75582 (0.1% higher), AMD EPYC 4545P at 75373 (0.2% lower), AMD Ryzen 7 PRO 9755X3D at 75716 (0.3% higher), and AMD Ryzen 7 PRO 9755 at 75738 (0.3% higher). AMD's nearest rivals are much closer in average score: AMD Ryzen 7 7700 at 40081 (0.1% higher), Intel Core 5 221E at 40144 (0.2% higher), AMD Ryzen 9 270 at 40246 (0.5% higher), and Intel Core i9-13905H at 40313 (0.7% higher). The data shows that the Ryzen AI 9 365 competes in a completely different performance tier than the Core Ultra 9 285.

The Verdict

The data points to a straightforward conclusion: the Intel Core Ultra 9 285 outperforms the AMD Ryzen AI 9 365 in every recorded benchmark. There is no single test where the AMD part takes the lead. The Intel processor wins by at least 21.3% in the PassMark single-thread test and by as much as 74.5% in the prime number test.

The segment difference matters for interpretation. The AMD Ryzen AI 9 365 is a mobile processor designed for a 28 W TDP, while the Intel Core Ultra 9 285 is a desktop processor with a 65 W TDP. The Intel part also carries a launch MSRP of $579. The performance gap should be understood in that context: the desktop part draws more power, uses a newer 3 nm process node from TSMC, and packs more than double the cores.

Buyers choosing between these two parts are not choosing within the same class. The Ryzen AI 9 365 belongs in thin-and-light laptops where power limits are tight. The Core Ultra 9 285 belongs in desktop towers where sustained power delivery and cooling are available. The benchmark data confirms that the desktop part delivers dramatically higher throughput across rendering, encryption, compression, and math workloads. The AMD part's 87th percentile ranking places it near the AMD Ryzen 7 7700, a desktop CPU from an older generation, while the Intel part's 95th percentile ranking places it near server-class EPYC processors.

The 20-thread count on the AMD part does not compensate for the core deficit. Intel's 24 cores and 24 threads produce scores that are roughly 1.5 to 4 times higher depending on the workload. The single-thread results are also consistently in Intel's favor, meaning the AMD part does not even offer a per-core efficiency advantage in these recorded tests.

Specification Differences

The two processors differ across nearly every core specification category. The AMD Ryzen AI 9 365 has 10 cores and 20 threads, while the Intel Core Ultra 9 285 has 24 cores and 24 threads. Base clocks are 2.00 GHz for AMD and 2.50 GHz for Intel, with boost clocks of 5.00 GHz and 5.60 GHz respectively. The TDP ratings are 28 W for AMD and 65 W for Intel.

The socket types are incompatible: AMD uses Socket FP8, Intel uses Socket 1851. The AMD part is a mobile processor, the Intel part is a desktop processor. AMD supports DDR5 and LPDDR5X memory, while Intel supports DDR5 only. Both use dual-channel memory buses, but the memory bandwidth differs: AMD records 89.6 GB/s, Intel records 102.4 GB/s. ECC memory support is present on the Intel part but absent on the AMD part.

PCIe specifications differ as well. AMD provides Gen 4 with 16 lanes (CPU only), while Intel provides Gen 5 with 20 lanes (CPU only). The integrated graphics differ: AMD uses the Radeon 880M, Intel uses the Arc Xe-LPG Graphics 64EU. The Intel part has a launch MSRP of $579; the AMD part has no recorded launch MSRP. Neither processor has an unlocked multiplier. The release dates are June 30, 2024 for AMD and December 31, 2024 for Intel.

Architecture Differences

The AMD Ryzen AI 9 365 uses the Zen 5 architecture under the codename Strix Point, belonging to the Ryzen AI 300 generation with a mix of Zen 5 and Zen 5c cores. It is built on a 4 nm process at TSMC with a die size of 233 mm². The Intel Core Ultra 9 285 uses the Arrow Lake architecture under the codename Arrow Lake-S, belonging to the Ultra 9 generation. It is built on a 3 nm process at TSMC with a die size of 243 mm² and 17,800 million transistors.

Cache layouts differ substantially. The AMD part has 80 KB of L1 per core, 1 MB of L2 per core, and 16 MB of L3 cache. The Intel part has 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3 cache. The Intel L3 cache is more than double the AMD L3 cache, which partially explains the large gap in the PassMark find prime numbers test, a workload that is highly cache sensitive.

The AMD part is built for the mobile segment with a 28 W TDP, while the Intel part targets the desktop segment with a 65 W TDP. The process node advantage goes to Intel at 3 nm versus AMD's 4 nm, both fabricated by TSMC. The Intel part's higher boost clock of 5.60 GHz versus 5.00 GHz contributes to its single-thread superiority in the recorded benchmarks.

Where Each One Wins

The Intel Core Ultra 9 285 wins in every recorded workload category. The data shows no use case where the AMD Ryzen AI 9 365 takes the lead. The Intel part is strongest relative to AMD in prime number finding (74.5% ahead), floating point math (67.8% ahead), and Cinebench R23 single-core (71.2% ahead). It is least dominant in PassMark single-thread (21.3% ahead) and integer math (38.2% ahead).

The AMD Ryzen AI 9 365's role in the data is as a comparison point for the mobile segment. Its 28 W TDP and 10-core configuration place it in the 87th percentile of all CPUs, alongside desktop parts like the AMD Ryzen 7 7700 and the Intel Core i9-13905H. The AMD part still delivers competitive single-thread performance relative to its own tier, trailing the Intel Core Ultra 9 285 by only 21.3% in the PassMark single-thread test, which is the narrowest gap recorded.

For workloads that demand maximum throughput, the Intel Core Ultra 9 285 is the clear choice based on the benchmark results. For power-constrained mobile systems, the AMD Ryzen AI 9 365 provides a more efficient platform at 28 W, though the recorded benchmarks do not include any power efficiency metric to quantify that trade-off. The data simply shows that the desktop part outperforms the mobile part in every measured dimension, with the largest advantages appearing in cache-heavy and floating-point-intensive tasks.
