Architecture Differences

The two processors come from different manufacturing and 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. The Intel Core Ultra X7 358H uses the Panther Lake codename and belongs to the Ultra X7 generation built on Panther Lake-H architecture. AMD fabricates its chip on a 4 nm process at TSMC, while Intel uses a 3 nm process at its own foundry. The AMD die measures 233 mm², while the Intel die size is not recorded in the database.

Core configurations differ significantly. The AMD chip has 12 cores and 24 threads, indicating simultaneous multithreading. The Intel chip has 16 cores but only 16 threads, meaning it does not implement hyper-threading in this configuration. The AMD chip runs at a 2.00 GHz base clock with a 5.10 GHz boost clock, while the Intel chip has a 1.90 GHz base clock and a 4.80 GHz boost clock. Both processors are locked, with multiplier unlocking set to false.

Cache hierarchies diverge in structure and size. The AMD chip provides 80 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of L3 cache. The Intel chip offers 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 18 MB of shared L3 cache.

Where Each One Wins

The AMD Ryzen AI Embedded P185 wins in workloads that emphasize integer arithmetic and data compression. The 41.7% lead in integer math indicates strong ALU throughput that benefits tasks such as database operations, cryptography aside, and general-purpose computation. The 12.6% advantage in data compression points to efficient handling of memory-bound data transformation workloads. The narrow 0.5% win in random string sorting rounds out the AMD chip's profile as a processor suited to data processing and sorting tasks. The AMD chip also carries ECC memory support, making it appropriate for environments where data integrity is a priority, and its 28 TDP rating with 24 threads provides a high thread count for parallel workloads.

The Intel Core Ultra X7 358H wins in the majority of benchmark categories, particularly those involving complex mathematical operations. The 61.7% lead in find prime numbers and the 32% lead in floating point math indicate strong execution units for scientific computing and numerical simulation. The 41.3% advantage in physics suggests good performance in simulation and modeling applications. The 24.7% lead in data encryption points to efficient cryptographic instruction handling. The Intel chip also wins in multithread performance by 5.9% despite having fewer threads, which indicates superior per-thread efficiency. Its 153.6 GB/s memory bandwidth, more than 70% higher than the AMD chip's 89.6 GB/s, supports memory-intensive workloads.

The Intel chip's 3.6% single-thread advantage means applications that depend heavily on single-core performance, such as legacy software or lightly threaded games, will generally favor the Intel part. The Intel chip's Gen 5 PCIe with 4 lanes offers higher per-lane bandwidth, which can benefit devices that use few lanes but require high throughput. The Intel chip's earlier release date by roughly eight weeks may indicate more mature platform support in the database.

The AMD chip's 24 threads versus 16 threads makes it the better choice for heavily threaded workloads that scale with thread count, provided the workload benefits from simultaneous multithreading. The AMD chip's 16 PCIe Gen 4 lanes provide more total lanes for multi-device configurations, even though the per-lane bandwidth is lower than Gen 5. The AMD chip's L3 cache is 16 MB versus 18 MB for Intel, a modest difference that slightly favors Intel for shared data access patterns.

The benchmark data shows a clear split: AMD leads in integer-centric and compression workloads, while Intel leads in floating-point, encryption, physics, and single-thread performance. The Intel chip wins 8 of 11 head-to-head tests, but the AMD chip maintains a higher average benchmark score and percentile ranking. The choice between these two processors ultimately depends on workload characteristics, with the AMD chip favoring data processing and the Intel chip favoring mathematical computation.
