AMD Ryzen AI Embedded P185 vs Intel Core Ultra 9 285K Comparison

Head-to-Head Benchmarks

The recorded data presents a clear and consistent picture: the Intel Core Ultra 9 285K wins every single head-to-head benchmark against the AMD Ryzen AI Embedded P185. Out of 11 direct comparisons, Intel takes 11, with no wins for AMD. This is not a narrow victory; the margins are substantial across every workload category.

The largest gap appears in the prime number finding test, where the Intel chip scores 541 against AMD's 129, a delta of -76.2%. This is a massive lead in a test that stresses integer throughput and branch prediction. The floating-point math test shows a similar story: Intel scores 224,324 versus 70,587, a 68.5% advantage. These two results alone indicate that the Intel part has a fundamentally higher computational ceiling for both integer and floating-point workloads.

Data encryption follows the same pattern. Intel scores 57,745, while AMD manages 19,612, a 66% deficit. This is particularly relevant for workloads that rely on AES or other cryptographic operations. Extended instructions also favor Intel heavily: 62,277 versus 26,544, a 57.4% delta. The random string sorting test, which measures memory access patterns and sorting efficiency, shows Intel at 94,927 versus 40,557, a 57.3% gap.

The multithreaded score, often a good summary of overall throughput, shows Intel at 67,260 versus 31,817, a 52.7% difference. The physics test, which often reflects simulation and rigid body dynamics, shows Intel at 3,938 versus 1,772, a 55% lead. Data compression is another decisive win: Intel scores 790,052 versus 374,429, a 52.6% delta.

Even the single-threaded tests, where AMD's Zen 5 architecture is often competitive, show a clear Intel advantage. The single-thread score is 5,087 for Intel versus 3,977 for AMD, a 21.8% gap. The integer math test is the closest relative margin on the list, but Intel still leads by 31.6%, scoring 172,379 versus 117,832.

The average benchmark score reflects this overall dominance. Intel's average is 83,807, while AMD's is 62,839. This places Intel in the 96th percentile of all CPUs in the database, while AMD sits in the 93rd percentile. The nearest rivals for each processor confirm their respective tiers: Intel's closest competitor is the Intel Core Ultra 9 290K Plus with a delta of -0.2%, while AMD's closest rival is the AMD Ryzen AI 9 PRO 465 with a delta of 0.5%.

The Verdict

The data is unambiguous. The Intel Core Ultra 9 285K is the faster processor in every measured category. The 24-core, 24-thread design with a 5.70 GHz boost clock outperforms the 12-core, 24-thread AMD part with its 5.10 GHz boost clock across all 11 head-to-head benchmarks. The margins range from 21.8% in single-threaded performance to 76.2% in prime number finding.

The Intel part also has a higher memory bandwidth at 102.4 GB/s versus 89.6 GB/s, which likely contributes to its lead in memory-sensitive tests like random string sorting and data compression. Its 36 MB of shared L3 cache is more than double AMD's 16 MB, further explaining the throughput advantage.

However, the AMD Ryzen AI Embedded P185 is not without its own merits. Its 28 W TDP is dramatically lower than Intel's 125 W TDP. The AMD part is designed for mobile and embedded use, while the Intel part is a desktop processor. The AMD chip uses the AMD Socket FP8, while Intel uses the Intel Socket 1851. These are different platforms for different use cases.

The launch MSRP of the Intel Core Ultra 9 285K is $589. The AMD part has no listed launch MSRP. The Intel processor has an unlocked multiplier, while the AMD part is locked. The Intel chip also supports PCIe Gen 5 with 20 lanes, while AMD supports PCIe Gen 4 with 16 lanes.

For anyone building a desktop workstation or high-performance PC, the Intel Core Ultra 9 285K is the clear choice based on benchmark data. For embedded or mobile systems where power consumption is a primary constraint, the AMD Ryzen AI Embedded P185 is the only sensible option, despite its lower scores.

Where Each One Wins

The Intel Core Ultra 9 285K wins in every benchmark category recorded. This includes single-threaded workloads, multithreaded workloads, integer math, floating-point math, data compression, data encryption, extended instructions, prime number finding, physics simulation, and random string sorting. There is no workload in the database where the AMD part comes out ahead.

The AMD part wins in efficiency, though not in raw performance. Its 28 W TDP is less than a quarter of Intel's 125 W TDP. This makes it suitable for fanless or low-power designs, battery-powered devices, or compact embedded systems. The AMD chip also uses the Radeon 890M integrated graphics, while Intel uses the Arc Xe-LPG Graphics 64EU. Both are capable of display output and light graphics work, but the database does not provide comparative graphics benchmarks.

The Intel part has a higher boost clock (5.70 GHz versus 5.10 GHz), more cores (24 versus 12), and more L3 cache (36 MB versus 16 MB). It also has a larger L1 cache per core (192 KB versus 80 KB) and more L2 cache per core (3 MB versus 1 MB). These architectural advantages translate directly into the benchmark results.

The AMD part is built on a 4 nm process, while Intel uses a 3 nm process. Both are fabricated by TSMC. Intel's die size is 243 mm² with 17,800 million transistors, while AMD's die size is 233 mm² with no transistor count listed. The smaller process node and larger transistor budget give Intel a structural advantage.
