AMD Ryzen AI Embedded P185 vs Intel Core Ultra 5 225F Comparison

Where Each One Wins

The benchmark split between the AMD Ryzen AI Embedded P185 and the Intel Core Ultra 5 225F is remarkably clean, with each processor dominating entirely different categories. The AMD part wins 4 of the 11 recorded head-to-head tests, while the Intel chip takes 7, but the nature of those wins tells the real story.

The AMD Ryzen AI Embedded P185 establishes its advantage in integer-heavy and parallel workloads. Its largest victory comes in PassMark integer math, where it scores 117832 against Intel's 66417, a massive 77.4% advantage. This is the single biggest delta in the entire comparison. The AMD processor also wins data compression with a score of 374429 versus 310843, a 20.5% lead. It edges out the Intel chip in multithread performance (31817 vs 31004, a 2.6% margin) and random string sorting (40557 vs 37325, an 8.7% lead). These results point to a processor that excels when handling large datasets, sorting operations, and parallel integer computation.

The Intel Core Ultra 5 225F counters with dominance in floating-point, encryption, and single-threaded tasks. Its most decisive win is in finding prime numbers, where it scores 352 against AMD's 129, a 63.4% advantage. The Intel processor also leads in floating-point math (92554 vs 70587, a 23.7% gap), physics calculations (2430 vs 1772, a 27.1% margin), and data encryption (22648 vs 19612, a 13.4% lead). In single-thread performance, the Intel chip scores 4397 versus 3977, a 9.6% advantage. It also wins extended instructions (28027 vs 26544, a 5.3% margin).

The use-case split is clear. The AMD Ryzen AI Embedded P185 suits workloads built around integer processing, data compression, and heavy multithreading. The Intel Core Ultra 5 225F fits tasks relying on floating-point math, cryptography, physics simulation, and single-thread responsiveness. The overall average benchmark scores reflect this divergence: AMD's avgBenchmarkScore is 62839 with a 93rd percentile ranking among all CPUs, while Intel's is 37313 with an 85th percentile ranking.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI Embedded P185 uses the Gorgon Point codename and belongs to the Ryzen AI Embedded generation built on Zen 5 and Zen 5c cores. It is manufactured on a 4 nm process at TSMC with a die size of 233 mm². The Intel Core Ultra 5 225F uses the Arrow Lake-S codename, belongs to the Core Ultra Series 2 generation, and implements the Arrow Lake architecture. It is built on a more advanced 3 nm process, also at TSMC, with a slightly larger die at 243 mm² and a transistor count of 17,800 million.

Core configurations differ significantly. The AMD processor has 12 cores and 24 threads, leveraging simultaneous multithreading. The Intel processor has 10 cores and 10 threads, with no hyperthreading. This explains why the AMD chip wins multithread benchmarks despite losing single-thread tests. The AMD part's base clock is 2.00 GHz with a boost of 5.10 GHz, while the Intel chip runs at a 3.30 GHz base and 4.90 GHz boost. The higher boost clock on the AMD side does not translate to single-thread wins, indicating architectural efficiency differences beyond raw frequency.

Cache hierarchies are also distinct. The AMD processor allocates 80 KB of L1 per core and 1 MB of L2 per core, with a 16 MB L3 cache. The Intel processor provides 192 KB of L1 per core and 3 MB of L2 per core, with a 20 MB shared L3. The larger per-core caches on the Intel side likely contribute to its single-thread and floating-point advantages.

The AMD chip includes the Radeon 890M integrated graphics, while the Intel part has no integrated graphics at all. Memory support differs as well: the AMD processor supports both DDR5 and LPDDR5X with ECC memory capability, while the Intel chip supports only DDR5 without ECC. The Intel processor offers a wider memory bandwidth at 102.4 GB/s versus 89.6 GB/s for AMD. PCIe connectivity also diverges, with AMD providing Gen 4 with 16 lanes (CPU only) and Intel providing Gen 5 with 20 lanes (CPU only).

Head-to-Head Benchmarks

The largest single victory belongs to the AMD Ryzen AI Embedded P185 in integer math. Its score of 117832 versus 66417 represents a 77.4% advantage, a staggering gap that dwarfs every other difference in this comparison. This result suggests that the Zen 5 and Zen 5c cores possess a substantial integer execution advantage over the Arrow Lake cores in this particular workload.

The AMD processor also demonstrates a strong 20.5% lead in data compression, scoring 374429 against Intel's 310843. This aligns with the integer math result, as compression algorithms rely heavily on integer operations. The multithread test shows a narrower 2.6% margin (31817 vs 31004), and random string sorting gives AMD an 8.7% edge (40557 vs 37325).

The Intel Core Ultra 5 225F answers with a 63.4% victory in prime number finding (352 vs 129). This test is notoriously sensitive to single-thread efficiency and branch prediction, areas where the Intel architecture clearly excels. The floating-point math test gives Intel a 23.7% margin (92554 vs 70587), and physics simulation shows a 27.1% advantage (2430 vs 1772). Data encryption favors Intel by 13.4% (22648 vs 19612), and extended instructions give Intel a 5.3% lead (28027 vs 26544).

Single-thread performance is decisively Intel's, with a 9.6% margin in both recorded single-thread tests (4397 vs 3977). This consistent gap across two identical test entries reinforces the conclusion that the Intel architecture delivers better per-thread performance despite having fewer cores and threads.

Specification Differences

The core and thread counts present the most fundamental difference. The AMD Ryzen AI Embedded P185 provides 12 cores and 24 threads, while the Intel Core Ultra 5 225F provides 10 cores and 10 threads. The AMD processor has a lower base clock of 2.00 GHz versus 3.30 GHz, but a higher boost clock of 5.10 GHz versus 4.90 GHz.

Thermal design power differs substantially: the AMD chip is rated at 28 W TDP, while the Intel chip is rated at 65 W TDP. This makes the AMD processor far more power-efficient on paper, though the Intel chip's higher power envelope may contribute to its performance advantages in certain tests.

The process nodes differ by one generation step: AMD uses 4 nm, Intel uses 3 nm. Both are fabricated by TSMC. The Intel chip has a documented transistor count of 17,800 million, while the AMD chip's transistor count is not recorded. Die sizes are close: 233 mm² for AMD, 243 mm² for Intel.

Cache configurations differ in both size and organization. AMD provides 80 KB L1 per core, 1 MB L2 per core, and 16 MB L3. Intel provides 192 KB L1 per core, 3 MB L2 per core, and 20 MB shared L3. The larger per-core caches on the Intel side are notable.

Memory support shows the AMD processor accepting both DDR5 and LPDDR5X with ECC support, while the Intel processor accepts only DDR5 without ECC. Memory bandwidth favors Intel at 102.4 GB/s versus 89.6 GB/s. PCIe generation and lane count favor Intel as well: Gen 5 with 20 lanes versus Gen 4 with 16 lanes.

The AMD processor includes Radeon 890M integrated graphics; the Intel processor has no integrated graphics. The AMD chip uses AMD Socket FP8, while the Intel chip uses Intel Socket 1851. Neither processor has an unlocked multiplier. The Intel chip carries a launch MSRP of $231 and a part number of SRQD2SRVF9, while the AMD chip's MSRP and part number are not recorded. The AMD processor released on 2026-02-28, and the Intel processor released on 2025-01-06. Both remain in active production.
