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

Where Each One Wins

The head-to-head benchmark data is unambiguous: the Intel Core Ultra 9 285T wins every single recorded comparison. Across all 11 benchmark categories, the Intel part posts higher scores, with the AMD Ryzen AI Embedded P185 failing to claim a single victory. The closest margin comes in data compression, where the Intel chip leads by only 2.5%, while the largest gap appears in prime number finding, where the Intel processor is ahead by 62.6%.

That said, the two processors occupy very different market positions. The AMD part is a mobile embedded processor with a 28 TDP, while the Intel part is a desktop chip with a 35 TDP. The AMD chip is built for power-constrained environments, and its benchmark profile reflects an emphasis on efficiency rather than raw throughput. The Intel chip, with 24 cores versus 12, naturally dominates in multithreaded workloads. The multithread score of 39931 for the Intel part against 31817 for the AMD part confirms this core-count advantage.

The Intel processor also holds the edge in single-thread performance, scoring 4576 versus 3977, a 13.1% difference. This matters for applications that rely on per-core speed, such as legacy software or lightly threaded tasks. The AMD part still delivers competitive single-thread numbers, but the data shows the Intel chip is faster in every measured scenario.

Architecture Differences

The architectural split is substantial. The AMD Ryzen AI Embedded P185 uses the Gorgon Point codename with a generation designation of Ryzen AI Embedded (Zen 5 / Zen 5c). It is built on a 4 nm process at TSMC with a die size of 233 mm². The Intel Core Ultra 9 285T uses the Arrow Lake architecture, specifically Arrow Lake-S, on a 3 nm process also at TSMC, with a die size of 243 mm² and 17,800 million transistors.

Core configurations diverge sharply. The AMD chip has 12 cores and 24 threads, while the Intel chip has 24 cores and 24 threads, meaning the Intel part relies on a different threading model with no hyperthreading. The AMD chip uses a hybrid Zen 5 / Zen 5c arrangement, though the exact core distribution is not recorded in the database. The Intel chip's cache hierarchy is larger across the board: 192 KB of L1 per core versus 80 KB, 3 MB of L2 per core versus 1 MB, and 36 MB of shared L3 versus 16 MB.

Memory support also differs. The AMD chip supports both DDR5 and LPDDR5X with dual-channel memory and 89.6 GB/s of bandwidth. The Intel chip supports DDR5 only, also dual-channel, but with higher bandwidth at 102.4 GB/s. Both support ECC memory. PCIe connectivity favors the Intel chip with Gen 5 and 20 lanes (CPU only), while the AMD chip offers Gen 4 with 16 lanes (CPU only).

Integrated graphics differ as well. AMD uses the Radeon 890M, while Intel uses Arc Xe-LPG Graphics 64EU. The sockets are incompatible: AMD Socket FP8 versus Intel Socket 1851. Neither processor has an unlocked multiplier. The release dates are also distinct, with the Intel part launching earlier and the AMD part appearing later in the database.

The Verdict

The data points to a clear performance hierarchy. The Intel Core Ultra 9 285T outperforms the AMD Ryzen AI Embedded P185 in every benchmark category recorded in the head-to-head comparison. The Intel chip leads by double-digit percentages in most tests: 38.8% in data encryption, 48.8% in floating point math, 20.3% in multithread, and 37.6% in physics. Even in the closest test, data compression, the Intel part still wins by 2.5%.

However, the selection depends on the use case. The AMD chip is a mobile embedded processor with a 28 TDP, suited for compact, power-limited systems. The Intel chip is a desktop part with a 35 TDP and a launch MSRP of $549, aimed at higher-performance desktop workloads. The Intel chip's 24 cores and 36 MB of L3 cache make it the stronger choice for heavily threaded applications. The AMD chip's 12 cores and 16 MB of L3 cache are more modest, but its lower TDP and support for LPDDR5X make it viable for embedded or mobile scenarios where thermal and power budgets are tight.

The percentile rankings reinforce the split. The AMD chip sits at the 93rd percentile among all CPUs, while the Intel chip sits at the 91st percentile. The AMD part's average benchmark score of 62839 is higher than the Intel part's 51310, which reflects the different benchmark suites recorded for each. The Intel part includes Cinebench scores in its database, while the AMD part does not, so direct average comparisons are not apples-to-apples. In the shared PassMark tests, the Intel chip wins all 11.

Users who need maximum throughput across all measured workloads should choose the Intel Core Ultra 9 285T. Users who require a lower-power embedded processor with competitive performance for its class should consider the AMD Ryzen AI Embedded P185. The data does not support any scenario where the AMD chip outpaces the Intel chip in raw performance.

Head-to-Head Benchmarks

The most decisive Intel victory occurs in the find prime numbers test. The Intel chip scores 345 against the AMD chip's 129, a 62.6% advantage. This test often reflects integer-heavy computational loops, and the Intel chip's higher core count and larger cache likely contribute. Floating point math shows a similar pattern: Intel scores 137923 versus 70587, a 48.8% lead. This is one of the largest absolute gaps in the dataset.

Data encryption also favors Intel heavily. The Intel chip posts 32061 versus 19612, a 38.8% difference. Physics follows at 2842 versus 1772, a 37.6% gap. Multithread performance shows a 20.3% Intel lead, with scores of 39931 and 31817 respectively. The Intel chip's 24 cores versus 12 explains much of this margin.

Integer math is closer but still Intel-favored: 132433 versus 117832, an 11% difference. Random string sorting shows a 15% Intel lead, 47695 versus 40557. Single-thread performance, recorded twice in the database with identical values, gives Intel a 13.1% edge at 4576 versus 3977.

The narrowest margin is data compression. The Intel chip scores 384140 against the AMD chip's 374429, a 2.5% gap. Extended instructions also stay relatively close: 27477 versus 26544, a 3.4% difference. These two tests show that the AMD chip can approach Intel's performance in specific workloads, but it never surpasses it.

The AMD chip's strongest relative showing is in data compression and extended instructions, where the Intel lead remains below 5%. Its weakest relative showing is in find prime numbers and floating point math, where the Intel lead exceeds 48%. No benchmark category records a win for the AMD part.
