AMD Ryzen 5 40 vs AMD Ryzen AI Embedded P185i Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Ryzen 5 40 and the AMD Ryzen AI Embedded P185i. The head-to-head table is empty, and the win counters for both processors are zero. This absence of direct comparison data means any assessment must rely on the individual benchmark scores recorded for the Ryzen 5 40 and the architectural specifications of the P185i.

For the Ryzen 5 40, the recorded Cinebench results show a multicore score of 4841 in Cinebench R23 and 790 in Cinebench R15. Single-core scores reach 1150 in Cinebench R23 and 165.5 in Cinebench R15. In PassMark testing, the processor achieves 9341 in multithread, 2477 in single-thread, 31598 in integer math, and 15194 in floating-point math. Data compression scores 141533, while data encryption records 6646. Extended instructions hit 6437, random string sorting reaches 15124, and find prime numbers scores 20. Physics performance is recorded at 432.

The Ryzen AI Embedded P185i has no benchmark entries in the database. Its average benchmark score is listed as 0, and it has no nearest rivals for contextual comparison. The percentile ranking for the P185i sits at 50, while the Ryzen 5 40 ranks at the 70th percentile among all CPUs in the database.

The Ryzen 5 40 shows an average benchmark score of 15882. Its nearest rivals in the database include the AMD EPYC 75F3 with an average score of 15859 (a 0.1% difference), the Intel Core Ultra 5 134U with 15910 (a 0.2% difference in the opposite direction), the AMD EPYC 9354P with 15826 (a 0.4% difference), and the AMD EPYC 9334 with 15940 (a 0.4% difference). These margins are all within 0.4%, placing the Ryzen 5 40 in a tightly clustered performance band. The data shows the Ryzen 5 40 sits essentially at parity with enterprise-class EPYC processors despite being a low-power mobile part.

The Verdict

Given the complete absence of benchmark data for the Ryzen AI Embedded P185i, the database cannot confirm any performance advantage for it. The P185i has a recorded average benchmark score of 0 and no entries in any test. The Ryzen 5 40, by contrast, has a full suite of 15 recorded benchmark results across Cinebench and PassMark tests.

The Ryzen 5 40 is the only processor in this comparison with measurable performance data. Its 70th percentile ranking indicates it outperforms the majority of CPUs in the database. The P185i's 50th percentile ranking, while not derived from direct measurements, places it at the median of all recorded processors. This percentile gap suggests the Ryzen 5 40 occupies a higher performance tier, but the lack of P185i test scores means this cannot be verified through direct comparison.

For workloads requiring proven, measurable performance, the data points squarely to the Ryzen 5 40. The P185i may offer architectural advantages on paper, but the database contains no evidence of its actual performance. Any selection between these two processors based strictly on recorded data must favor the Ryzen 5 40, as it is the only part with confirmed benchmark results.

Architecture Differences

The two processors come from different architectural generations and manufacturing nodes. The Ryzen 5 40 uses the Zen 2 architecture with the Mendocino codename, built on a 6 nm process at TSMC with a die size of 100 mm². The Ryzen AI Embedded P185i uses the Gorgon Point codename with a Zen 5 / Zen 5c generation, built on a 4 nm process at TSMC with a die size of 233 mm².

Core configurations differ substantially. The Ryzen 5 40 has 4 cores and 8 threads, while the P185i has 12 cores and 24 threads. The P185i's hybrid core arrangement with Zen 5 and Zen 5c cores explains the larger physical footprint. Cache hierarchies also diverge: the Ryzen 5 40 carries 64 KB of L1 cache per core, 512 KB of L2 per core, and 4 MB of shared L3 cache. The P185i carries 80 KB of L1 per core, 1 MB of L2 per core, and 16 MB of L3 cache.

The P185i has a smaller transistor count advantage in terms of density due to the 4 nm node, though exact transistor counts are not recorded for either processor. The process node difference from 6 nm to 4 nm represents a significant manufacturing advancement, allowing the P185i to pack more cores and cache into a larger die while maintaining power efficiency.

The integrated graphics differ as well. The Ryzen 5 40 uses the Radeon 610M, while the P185i uses the Radeon 890M. The newer Radeon 890M reflects the more recent GPU architecture available in the Zen 5 generation.

Specification Differences

The two processors differ across nearly every measurable specification. Clock speeds show a notable split: the Ryzen 5 40 has a base clock of 2.80 GHz and a boost clock of 4.30 GHz, while the P185i has a lower base clock of 2.00 GHz but a higher boost clock of 5.10 GHz. The P185i's higher boost clock compensates for its lower base frequency, suggesting a design that scales aggressively under load.

Power envelopes differ, with the Ryzen 5 40 rated at a 15 W TDP and the P185i at 28 W. The higher TDP for the P185i supports its additional cores and higher boost ceiling. Socket compatibility is distinct: the Ryzen 5 40 uses the AMD Socket FT6, while the P185i uses the AMD Socket FP8.

Memory support diverges significantly. The Ryzen 5 40 supports LPDDR5 memory with dual-channel configuration and a memory bandwidth of 88.0 GB/s. The P185i supports both DDR5 and LPDDR5X with dual-channel configuration and a slightly higher memory bandwidth of 89.6 GB/s. The P185i also supports ECC memory, while the Ryzen 5 40 does not.

PCIe connectivity shows a major gap. The Ryzen 5 40 provides PCIe Gen 3 with 4 lanes (CPU only), while the P185i provides PCIe Gen 4 with 16 lanes (CPU only). This quadrupling of available lanes and the newer PCIe generation gives the P185i substantially more expansion capability.

The Ryzen 5 40 has a release date of September 30, 2025, while the P185i has a later release date of February 28, 2026. Both processors are listed as Active in production status and neither has a recorded launch MSRP. Both processors have locked multipliers and unknown part numbers. Both target the mobile market segment.

Where Each One Wins

The Ryzen 5 40 wins in every category where recorded data exists. It has a complete benchmark suite with 15 recorded test scores, an average benchmark score of 15882, and a 70th percentile ranking. Its nearest rivals in the database are all within 0.4% of its average score, confirming it delivers competitive performance in its tier. The 15 W TDP makes it a low-power option suitable for compact mobile systems, and its smaller 100 mm² die reflects a more modest manufacturing footprint.

The Ryzen AI Embedded P185i wins on paper specifications. It has triple the cores and threads, a 0.80 GHz higher boost clock, a newer 4 nm process node, and a larger 16 MB L3 cache compared to 4 MB on the Ryzen 5 40. It supports both DDR5 and LPDDR5X memory with ECC capability, provides PCIe Gen 4 with 16 lanes versus Gen 3 with 4 lanes, and features the Radeon 890M integrated graphics. Its memory bandwidth of 89.6 GB/s edges out the Ryzen 5 40's 88.0 GB/s.

For workloads that depend on multi-core throughput, the P185i's 12 cores and 24 threads provide a theoretical advantage, though no benchmark data confirms this. For single-core performance, the P185i's 5.10 GHz boost clock suggests strong performance, but again, no measurements exist. The P185i's ECC memory support makes it suitable for reliability-sensitive embedded applications, while its PCIe Gen 4 with 16 lanes accommodates more expansion devices.

The Ryzen 5 40 wins in demonstrated performance, power efficiency, and database ranking. The P185i wins in raw specification count, connectivity options, and memory flexibility. Without benchmark data for the P185i, the only measurable victory belongs to the Ryzen 5 40.
