AMD Ryzen AI Embedded P185 vs Intel Core Ultra 9 386H Comparison

Where Each One Wins

The benchmark split between the AMD Ryzen AI Embedded P185 and the Intel Core Ultra 9 386H is lopsided, with Intel taking 9 of 11 head-to-head tests. The AMD processor wins only two tests: data compression and integer math. That pairing suggests a workload profile built around arithmetic-heavy, compression-oriented tasks where the AMD part’s 24 threads provide a structural advantage. The Intel part, by contrast, dominates across floating point, encryption, prime number finding, physics simulation, random string sorting, multithreaded throughput, and single-thread performance.

The single-thread result matters for everyday responsiveness. Intel leads the PassMark single-thread test with 4218 against 3977, a 5.7% margin. That edge carries into the physics test, where Intel scores 3028 versus 1772, a 41.5% gap. Physics simulations tend to scale with fast cores and efficient instruction handling, and the data reflects that. For users running simulation-heavy code, the Intel chip is the clear choice.

The AMD chip’s two wins are not trivial. Data compression at 374429 versus 352365 is a 6.3% advantage, and integer math at 117832 versus 87284 is a full 35% lead. Integer math is foundational for database operations, financial calculations, and general office productivity. The AMD part’s 12 cores and 24 threads allow it to process parallel integer workloads more effectively than Intel’s 16 cores and 16 threads, which lack simultaneous multithreading. The result is a processor that wins where raw integer throughput matters but loses everywhere else.

Architecture Differences

The two processors come from 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 / Zen 5c cores. It is fabricated on a 4 nm process at TSMC with a die size of 233 mm². The Intel Core Ultra 9 386H uses the Panther Lake architecture, specifically Panther Lake-H, built on Intel’s 3 nm process. The process node difference is small, but the design choices diverge sharply.

Core counts differ significantly. AMD provides 12 cores and 24 threads, while Intel provides 16 cores and 16 threads. Intel’s lack of simultaneous multithreading means its 16 cores handle 16 threads, whereas AMD’s 12 cores each handle two threads. This explains the AMD integer math and compression wins: more threads available for parallel integer work. Intel compensates with more physical cores and a higher base clock. AMD runs at a 2.00 GHz base with a 5.10 GHz boost, while Intel runs at 2.10 GHz base and 4.90 GHz boost. The Intel base clock is slightly higher, but AMD has the higher boost ceiling.

Cache hierarchies also differ. AMD uses 80 KB L1 per core, 1 MB L2 per core, and 16 MB L3. Intel uses 192 KB L1 per core, 2.5 MB L2 per core, and 18 MB shared L3. Intel’s larger per-core L1 and L2 caches, combined with a larger shared L3, help explain its floating point and single-thread advantages. The memory bandwidth figures reinforce this: Intel delivers 115.2 GB/s versus AMD’s 89.6 GB/s, both over dual-channel DDR5 or LPDDR5X memory.

Platform features differ as well. AMD supports ECC memory; Intel does not. AMD uses PCIe Gen 4 with 16 CPU lanes, while Intel uses PCIe Gen 5 with 12 CPU lanes. Intel’s PCIe Gen 5 offers higher per-lane bandwidth, but AMD provides more total lanes. Integrated graphics differ: AMD uses the Radeon 890M, Intel uses Intel Xe3 Graphics. Both are mobile parts, with TDP ratings of 28 W for AMD and 25 W for Intel. The Intel part has a lower TDP despite more cores, a result of the 3 nm process and the absence of multithreading overhead.

Head-to-Head Benchmarks

The largest Intel win comes in the prime number test. Intel scores 341 against AMD’s 129, a 62.2% advantage. Prime number finding is highly dependent on integer division and branch prediction, and the Intel architecture handles it far better. The floating point math test also heavily favors Intel: 108527 versus 70587, a 35% gap. This is the largest absolute point difference in the entire comparison, with Intel leading by 37940 points. The physics test shows a 41.5% Intel lead, and data encryption shows a 27.8% Intel lead at 27150 versus 19612. Extended instructions go to Intel by 8.9%, random string sorting by 3.7%, and multithread by 10.1% at 35399 versus 31817.

The AMD wins are concentrated in integer math and data compression. The integer math result of 117832 versus 87284 is a 35% AMD lead, exactly matching the inverse of Intel’s floating point margin. This symmetry suggests the two chips are optimized for different math domains: AMD for integer throughput, Intel for floating point throughput. Data compression at 374429 versus 352365 is a 6.3% AMD win, driven largely by thread count.

Single-thread performance favors Intel at 4218 versus 3977, a 5.7% margin. This is consistent across both PassMark single-thread listings in the database. The multithread test, however, shows Intel winning at 35399 versus 31817 despite having fewer threads. This indicates that Intel’s 16 physical cores outperform AMD’s 24 threads in mixed workloads, likely due to higher per-core efficiency and the larger cache hierarchy.

The Cinebench R23 multicore score for Intel is 20547 and the single-core score is 2071.5, which pulls down the average relative to AMD’s PassMark-only average.

The Verdict

The recorded data points to a clear split. The Intel Core Ultra 9 386H wins 9 of 11 head-to-head benchmarks, including all floating point, encryption, physics, and single-thread tests. It also wins the multithread test despite having fewer threads than the AMD part. The Intel chip is the better all-around performer for most workloads, especially those involving floating point math, physics simulation, encryption, or single-thread responsiveness.

The AMD Ryzen AI Embedded P185 wins only two tests, but those wins are meaningful. The 35% integer math lead and the 6.3% data compression lead suggest the AMD part is better suited for integer-heavy parallel workloads such as database processing, compression tasks, and certain financial calculations. The 24 threads give it a scheduling advantage in workloads that can use more than 16 threads effectively.

The Intel part also offers higher memory bandwidth at 115.2 GB/s versus 89.6 GB/s, larger caches, and PCIe Gen 5 support. The AMD part offers ECC memory support, a higher boost clock of 5.10 GHz, and a lower 28 W TDP compared to Intel’s 25 W. The percentile ranking favors AMD at 93 versus Intel’s 88, but that ranking is based on different benchmark sets and should not be read as a direct performance comparison.

For buyers prioritizing floating point performance, physics, encryption, and single-thread speed, the Intel Core Ultra 9 386H is the data-backed choice. For buyers prioritizing integer math, data compression, and ECC memory support, the AMD Ryzen AI Embedded P185 delivers specific advantages in those narrow domains. The overall benchmark record favors Intel by a wide margin, with the AMD chip winning only where its thread count and integer throughput can overcome Intel’s architectural advantages.
