AMD Ryzen AI Embedded P185 vs AMD Ryzen Embedded 8845HS Comparison

Where Each One Wins

The recorded data splits these two AMD embedded processors along clear lines. The Ryzen AI Embedded P185 wins every single benchmark category where both parts have recorded scores. The P185 shows a 12-core, 24-thread configuration against the 8845HS's 8-core, 16-thread setup, and that advantage shows up across the entire PassMark suite. The P185's average benchmark score sits at 62,839, placing it in the 93rd percentile of all CPUs in the database. The 8845HS has no individual benchmark scores recorded, so its percentile ranking of 50 and average score of zero reflect the absence of data rather than a measured performance level.

The P185's strongest absolute results come in data-intensive workloads. Its PassMark data compression score reaches 374,429, which towers over its other recorded results. Integer math scores 117,832, floating point math scores 70,587, and multithreaded performance scores 31,817. These are the workloads where the extra four cores and eight threads deliver the largest measurable advantage. The single-thread score of 3,977 confirms that the P185 also handles lightly threaded tasks well, though this figure is less dominant relative to its own multithreaded results.

The 8845HS, by contrast, has no recorded benchmark scores in the database. This means the analysis cannot assign it any wins based on measured performance. Its higher base clock of 3.80 GHz compared to the P185's 2.00 GHz suggests a different design philosophy, one that favors sustained frequency at a higher 45 W TDP rather than the P185's 28 W envelope. But without benchmark data, the database cannot confirm how that base clock translates into real-world results. The P185 wins all measurable categories by default, and the 8845HS's case rests entirely on architectural specifications rather than recorded performance.

Architecture Differences

Both processors use TSMC's 4 nm process node and fit into the same AMD Socket FP8, but their internal designs diverge significantly. The P185 uses the Gorgon Point codename and belongs to the Ryzen AI Embedded generation built on a hybrid Zen 5 / Zen 5c core arrangement. The 8845HS uses the Hawk Point codename and the 8000 series, built entirely on Zen 4 architecture. This generational gap explains several specification differences beyond the core count.

The P185 packs 12 physical cores and 24 threads, while the 8845HS provides 8 cores and 16 threads. The P185's die measures 233 mm², notably larger than the 8845HS's 178 mm². The 8845HS has a recorded transistor count of 25,000 million, while the P185's transistor count is not listed. Both chips share the same 1 MB L2 cache per core and 16 MB of L3 cache, though the P185 lists its L3 as 16 MB without specifying shared allocation, while the 8845HS explicitly lists 16 MB shared. Per-core L1 cache differs: the P185 provides 80 KB per core against the 8845HS's 64 KB per core.

Clock behavior presents a striking contrast. The 8845HS starts at a much higher 3.80 GHz base clock, while the P185 idles at a conservative 2.00 GHz base. Both reach the same 5.10 GHz boost clock. The TDP figures reflect this difference: the P185 consumes 28 W, while the 8845HS draws 45 W. The P185 achieves its higher core count and lower base clock within a tighter power envelope, suggesting the Zen 5c efficiency cores play a role in its design. The 8845HS uses its higher base clock and higher TDP to push frequency from the outset with fewer cores.

Memory support shows another split. Both processors support dual-channel memory with 89.6 GB/s bandwidth and ECC memory, but the P185 extends support to both DDR5 and LPDDR5X, while the 8845HS lists only DDR5. PCIe lane counts also differ: the P185 provides Gen 4 with 16 lanes from the CPU, while the 8845HS provides Gen 4 with 20 lanes. The integrated graphics differ as well, with the P185 using the Radeon 890M and the 8845HS using the Radeon 780M. Both target the mobile market segment and remain in active production, with the P185 released later (2026-02-28) than the 8845HS (2024-04-01). Neither processor has an unlocked multiplier, and neither has a recorded launch MSRP.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between these two processors, and the 8845HS has no individual benchmark scores. The comparison therefore rests on the P185's recorded PassMark results against the 8845HS's absence of recorded data. The P185's nearest rivals provide context for interpreting its scores, all of which are Intel or AMD parts with average scores within a narrow band.

The P185's average benchmark score of 62,839 places it 0.2% ahead of the Intel Core Ultra 7 255HX (62,738), 0.5% ahead of the AMD Ryzen AI 9 PRO 465 (62,498), 0.4% behind the Intel Core i7-13790F (63,080), and 0.5% behind the Intel Core Ultra 7 265HX (63,173). These deltas are small, indicating that the P185 sits in a tightly contested performance tier despite its 93rd percentile ranking. The largest measured gap in either direction is just 0.5%, which suggests the P185's positioning depends more on its specific feature set than on raw score dominance.

Within the P185's own benchmark suite, the multithreaded score of 31,817 and the single-thread score of 3,977 both fall into expected ranges for a 12-core hybrid part. The data encryption score of 19,612 and the extended instructions score of 26,544 indicate strong cryptographic and SIMD throughput. The find prime numbers score of 129 is the lowest recorded result, which reflects the integer-heavy, single-threaded nature of that workload. The random string sorting score of 40,557 and the physics score of 1,772 round out the suite. The P185's 93rd percentile placement across all CPUs in the database, combined with its narrow rival deltas, paints a picture of a processor that is competitive with the top tier but not decisively ahead of its closest alternatives.

The 8845HS's lack of recorded scores means no delta calculations are possible against the P185. Its 50th percentile ranking and zero average score in the database are placeholder values, not measured outcomes. Readers should treat the 8845HS's performance as unquantified rather than poor.

The Verdict

The data supports a clear split in use cases. The Ryzen AI Embedded P185 is the choice for workloads that scale with core count and thread count. Its 12 cores, 24 threads, and 28 W TDP deliver a 93rd percentile average benchmark score of 62,839, with the multithreaded score of 31,817 and data compression score of 374,429 standing as the standout results. The P185's Zen 5 / Zen 5c hybrid architecture, larger 233 mm² die, 80 KB per-core L1 cache, and support for both DDR5 and LPDDR5X make it the more feature-complete part. Its lower base clock of 2.00 GHz is offset by the same 5.10 GHz boost as the 8845HS, and the lower 28 W TDP gives it an efficiency profile that the 45 W 8845HS cannot match on paper.

The Ryzen Embedded 8845HS appeals to designs that prioritize a higher base clock of 3.80 GHz and a simpler 8-core Zen 4 layout. Its 25,000 million transistors, 178 mm² die, and 20 PCIe Gen 4 lanes provide a solid foundation for embedded applications that do not need the P185's core count. The 8845HS also carries the Radeon 780M integrated graphics, a step below the P185's Radeon 890M, and its memory support is limited to DDR5. With no recorded benchmark scores, the 8845HS cannot be positioned as a performance leader in the database; it remains a specification-defined alternative for systems where the higher base clock and lower complexity take priority.

Neither processor has a recorded launch MSRP, so no cost-based comparison is possible from the data. The P185's later release date, hybrid core design, and broader memory support indicate a newer platform, while the 8845HS's earlier release and conventional Zen 4 layout represent the prior generation. For embedded designs that need maximum throughput per watt, the P185's 28 W TDP and 12-core configuration make it the data-backed winner. For designs that need a higher base clock and fewer cores, the 8845HS remains a viable option, but its performance cannot be verified from the database.
