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

Head-to-Head Benchmarks

The recorded data presents a complete sweep for the Intel Core Ultra 9 285K across all 17 head-to-head benchmark comparisons. The AMD Ryzen AI 9 365 does not register a single win in any recorded test. This is not a close contest by any metric; the Intel part leads by substantial double-digit margins in every workload category.

The most significant gap appears in the PassMark find prime numbers test. The Intel chip scores 541 against the AMD's 117, a delta of -78.4%. This test is heavily integer-dependent and scales with core count, so the disparity is expected given the hardware specifications. Similarly, floating-point math shows a -72% delta, with Intel scoring 224,324 to AMD's 62,802. These two results highlight the raw computational throughput difference between a desktop flagship and a mobile-focused processor.

In multi-threaded workloads, the Intel chip is consistently more than twice as fast. Cinebench R23 multicore shows a score of 42,522 for Intel versus 18,698 for AMD, a -56% delta. The Geekbench multicore result is 26,702 against 13,760, a -48.5% delta. PassMark multithread follows the same pattern, Intel at 67,260 and AMD at 29,467, a -56.2% delta. The data confirms that for heavily parallelized tasks, the 285K delivers roughly double the performance of the 365.

Single-thread performance tells a similar story, though with narrower margins. Cinebench R23 single-core shows Intel at 2,377 versus AMD's 1,992, a -16.2% delta. Geekbench single-core is 2,870 against 2,253, a -21.5% delta. PassMark single-thread shows 5,087 versus 3,841, a -24.5% delta. The Intel part wins the single-threaded race by a meaningful margin, but the gap is far smaller than in multi-threaded tests. This indicates the AMD Zen 5 architecture is competitive on a per-core basis, while the Intel design relies on its much higher core count and boost clock to pull ahead.

The data encryption test shows the largest raw score gap. Intel scores 57,745 versus AMD's 18,297, a -68.3% delta. Data compression shows Intel at 790,052 versus 354,510, a -55.1% delta. Extended instructions also favor Intel heavily, 62,277 against 25,113, a -59.7% delta. These results all point to the same conclusion: the Intel part has a commanding lead in both integer and floating-point throughput, as well as in specialized instruction workloads.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI 9 365 uses the Zen 5 architecture, codenamed Strix Point, and belongs to the Ryzen AI 300 generation. It is built on a 4 nm process node at TSMC, with a die size of 233 mm². The Intel Core Ultra 9 285K uses the Arrow Lake architecture, codenamed Arrow Lake-S, and belongs to the Ultra 9 generation. It is built on a 3 nm process node, also at TSMC, with a die size of 243 mm² and a transistor count of 17,800 million.

The core configuration differs significantly. The AMD chip has 10 cores and 20 threads, while the Intel chip has 24 cores and 24 threads. The Intel part does not use simultaneous multithreading, which explains why its thread count equals its core count. The AMD part uses SMT, doubling its threads to 20 from 10 physical cores.

Cache hierarchy is another major differentiator. The AMD chip has 80 KB of L1 cache per core and 1 MB of L2 cache per core, with a 16 MB L3 cache. The Intel chip has 192 KB of L1 cache per core and 3 MB of L2 cache per core, with a much larger 36 MB shared L3 cache. The larger per-core cache allocations and the bigger L3 pool on the Intel part contribute to its higher benchmark scores.

The integrated graphics also differ. The AMD chip uses a Radeon 880M, while the Intel chip uses Arc Xe-LPG Graphics with 64 EU. These are integrated solutions, not discrete GPUs, but they indicate different graphics capabilities. The Intel chip supports ECC memory, while the AMD chip does not. The Intel chip also has an unlocked multiplier for overclocking, while the AMD chip's multiplier is locked.

Specification Differences

The two processors differ on nearly every key specification field. The AMD Ryzen AI 9 365 has a base clock of 2.00 GHz and a boost clock of 5.00 GHz. The Intel Core Ultra 9 285K has a base clock of 3.70 GHz and a boost clock of 5.70 GHz. Both base and boost clocks are higher on the Intel part.

Power consumption is a major divergence. The AMD chip has a TDP of 28 watts, while the Intel chip has a TDP of 125 watts. This reflects the mobile versus desktop market segmentation. The AMD chip uses the AMD Socket FP8, while the Intel chip uses the Intel Socket 1851.

Memory support shows another difference. The AMD chip supports both DDR5 and LPDDR5X memory, while the Intel chip supports DDR5 only. The memory bus is dual-channel on both, but the Intel chip has a higher memory bandwidth of 102.4 GB/s versus the AMD's 89.6 GB/s. The Intel chip supports ECC memory; the AMD chip does not.

PCIe connectivity is different. The AMD chip uses Gen 4 with 16 lanes (CPU only), while the Intel chip uses Gen 5 with 20 lanes (CPU only). The Intel chip offers both a newer PCIe generation and more lanes. The market segment also differs: the AMD chip is classified as Mobile, while the Intel chip is classified as Desktop.

The release dates are both in 2024, with the AMD chip released on 2024-06-30 and the Intel chip released on 2024-10-23. The Intel chip has a launch MSRP of $589. The AMD chip has no recorded launch MSRP. The part numbers differ as well: the AMD chip is 100-000001530, and the Intel chip is SRQD5.

The Verdict

The data presents a clear hierarchy. The Intel Core Ultra 9 285K is the dominant performer in every recorded benchmark. It wins all 17 head-to-head comparisons, with deltas ranging from -15.6% in Cinebench R15 single-core to -78.4% in PassMark find prime numbers. The Intel part sits in the 96th percentile of all CPUs, while the AMD part sits in the 87th percentile.

The AMD Ryzen AI 9 365 is not a competitor in raw performance terms. Its average benchmark score is 40,048, which is less than half of the Intel's 83,807. The nearest rivals to the AMD chip include the AMD Ryzen 7 7700, the Intel Core 5 221E, and the AMD Ryzen 9 270, all with average scores within 0.7% of the 365. The Intel chip's nearest rivals are the Intel Core Ultra 9 290K Plus, the AMD EPYC 4584PX, and the AMD EPYC 9135, all within 1.5% of the 285K.

The choice between these two processors depends entirely on the intended use case. The Intel Core Ultra 9 285K is a desktop part with a 125 watt TDP, 24 cores, and a 5.70 GHz boost clock. It is designed for maximum throughput in multi-threaded workloads, as evidenced by its 42,522 Cinebench R23 multicore score. The AMD Ryzen AI 9 365 is a mobile part with a 28 watt TDP, 10 cores, and a 5.00 GHz boost clock. It is designed for efficiency and portability, not for competing with desktop flagships.

For anyone building a high-performance desktop workstation or gaming rig, the Intel chip is the only choice based on the recorded performance data. For a thin-and-light laptop where power draw and thermals matter, the AMD chip offers a capable mobile solution. The data does not suggest any scenario where the AMD chip outperforms the Intel chip, so the decision rests on platform requirements rather than benchmark results.
