AMD Ryzen AI Embedded P185 vs AMD Ryzen Embedded 8840U Comparison

Head-to-Head Benchmarks

The recorded data contains a complete benchmark profile for the AMD Ryzen AI Embedded P185, while the AMD Ryzen Embedded 8840U has no individual benchmark scores listed in the database. This makes a direct score-by-score comparison impossible. However, the P185's aggregate performance can be positioned against the field. The P185 holds a 93rd percentile ranking among all CPUs, with an average benchmark score of 62,839. Its nearest rival, the Intel Core Ultra 7 255HX, scores 62,738, a delta of 0.2 percent in favor of the P185. The Intel Core i7-13790F sits slightly ahead at 63,080, a 0.4 percent margin over the P185. The Intel Core Ultra 7 265HX posts 63,173, which is 0.5 percent higher. The AMD Ryzen AI 9 PRO 465 trails at 62,498, putting the P185 0.5 percent ahead.

Within the P185's own benchmark suite, the strongest results appear in data compression, integer math, and single-thread workloads. The PassMark data compression score is 374,429, while integer math reaches 117,832. Single-thread performance is recorded at 3,977. Floating point math scores 70,587. Random string sorting completes at 40,557. Extended instructions hit 26,544. Data encryption scores 19,612. The multithread score is 31,817, and the physics score is 1,772. Find prime numbers returns 129.

Because the 8840U lacks any benchmark entries, the head-to-head comparison relies entirely on the P185's standalone metrics. The database shows zero wins for each processor in the head-to-head array, which reflects the absence of paired test data rather than a competitive outcome. The P185's multithread score of 31,817 and single-thread score of 3,977 establish a baseline, but no equivalent figures exist for the 8840U to set against them. The percentile gap is stark: the P185 sits at 93, while the 8840U sits at 50. The average benchmark score for the 8840U is listed as 0, indicating no recorded measurements.

Architecture Differences

The two processors share several foundational traits. Both use the AMD Socket FP8, both are built on a 4 nm TSMC process, and both support dual-channel memory with 89.6 GB/s of bandwidth. Both also support ECC memory. The similarities end there.

The P185, codenamed Gorgon Point, belongs to the Ryzen AI Embedded generation built on Zen 5 and Zen 5c cores. It offers 12 cores and 24 threads. The 8840U, codenamed Hawk Point, uses Zen 4 architecture and provides 8 cores and 16 threads. The P185's base clock is 2.00 GHz, while the 8840U starts at 3.30 GHz. Both reach the same 5.10 GHz boost clock. The P185 has a die size of 233 mm², compared to the 8840U's 178 mm². The 8840U lists a transistor count of 25,000 million; the P185 does not have a recorded transistor figure.

Cache layouts differ in the L1 tier. The P185 provides 80 KB of L1 per core, while the 8840U provides 64 KB per core. Both have 1 MB of L2 per core. The L3 cache is 16 MB in both cases, though the 8840U specifies it as shared. Memory support differs as well: the P185 accepts DDR5 and LPDDR5X, while the 8840U lists only DDR5. PCIe lane counts also diverge. The P185 offers Gen 4 with 16 lanes from the CPU, while the 8840U offers Gen 4 with 20 lanes.

Integrated graphics separate the two further. The P185 carries a Radeon 890M, while the 8840U uses a Radeon 780M. The P185 has no series designation in the database, while the 8840U belongs to the 8000 series. The P185's production status is active with a release date of 2026-02-28, whereas the 8840U is also active but released on 2024-04-01. Neither processor has an unlocked multiplier, and neither has a launch MSRP recorded.

The core count difference is the most consequential architectural gap. Twelve cores versus eight cores, combined with 24 threads versus 16 threads, gives the P185 a substantial parallelism advantage. The higher base clock on the 8840U suggests better responsiveness at lower loads, but the boost clocks match at 5.10 GHz. The process node is identical, so thermal and power characteristics likely follow similar curves, though the P185's larger die and additional cores imply higher complexity. The 8840U's smaller die and lower core count may translate to simpler power management in constrained embedded chassis.

Where Each One Wins

The P185 wins in any workload that scales with core count or thread count. Its 12 cores and 24 threads outperform an 8-core, 16-thread part in multithreaded throughput by structural necessity. The recorded multithread score of 31,817, while not directly comparable to the 8840U's absent data, indicates strong parallel execution capability. The P185 also wins on memory flexibility, accepting both DDR5 and LPDDR5X, which broadens its applicability in embedded designs that favor low-power memory. Its larger L1 cache at 80 KB per core provides more per-thread data locality, which can benefit latency-sensitive integer workloads. The P185's 93rd percentile ranking places it firmly among high-end mobile processors, and its nearest rivals are all recent Intel HX-series parts or AMD Ryzen AI 9 parts.

The 8840U wins on raw single-thread headroom at low utilization. Its 3.30 GHz base clock is 65 percent higher than the P185's 2.00 GHz base clock, so lightly threaded tasks that do not boost will complete faster on the 8840U. The 8840U also offers more PCIe lanes at 20 versus 16, which matters for embedded systems driving multiple peripherals directly from the CPU. Its smaller die at 178 mm² versus 233 mm² suggests lower manufacturing complexity, and its earlier release date means a longer field history. The 8840U's 50th percentile ranking places it at the median of all CPUs, which is a reasonable position for mid-range embedded deployments. The P185's 93rd percentile is a high-end position, but that ranking comes with the architectural cost of a larger die and more cores.

For workloads that are primarily single-threaded and do not benefit from boosting, the 8840U's higher base clock gives it an edge. For workloads that are heavily multithreaded, such as data compression, encryption, or parallel compilation, the P185's core advantage should dominate. The P185's LPDDR5X support also gives it a memory ecosystem advantage in power-constrained embedded designs, while the 8840U's DDR5-only support limits it to standard DDR5 modules. Neither processor has a vCache 3D option, so L3 capacity is fixed at 16 MB for both.

The Verdict

The data supports a clear split. The AMD Ryzen AI Embedded P185 is the higher-performance part by every recorded metric. Its 93rd percentile ranking, average score of 62,839, and nearest rivals within 0.5 percent all indicate a top-tier mobile processor. The 12-core, 24-thread configuration with Zen 5 and Zen 5c cores provides substantial multithreaded capability, and the LPDDR5X support adds memory flexibility. Its release date of 2026-02-28 makes it a newer design.

The AMD Ryzen Embedded 8840U occupies a different position. With 8 cores and 16 threads on Zen 4, it is a mid-range part at the 50th percentile. Its higher base clock of 3.30 GHz gives it a low-load advantage, and its 20 PCIe lanes exceed the P185's 16. The smaller die and earlier release date suggest a more mature, compact solution for embedded applications that do not require top-end throughput.

The database contains no head-to-head benchmark entries and no individual scores for the 8840U, so a direct performance delta cannot be quantified. What is clear is that the P185 is positioned for high-end embedded workloads that demand parallel compute, while the 8840U is positioned for balanced, mid-range deployments. For a system that needs maximum multithreaded throughput, the P185 is the only choice between the two based on recorded data. For a system that values higher base clocks, more PCIe lanes, and a longer production history, the 8840U has structural advantages. The P185's 93rd percentile and the 8840U's 50th percentile summarize the performance gap without requiring additional context.
