AMD Ryzen AI Embedded P185i vs AMD Ryzen Embedded 8845HS Comparison

Head-to-Head Benchmarks

The database currently holds no head-to-head benchmark results for the AMD Ryzen AI Embedded P185i versus the AMD Ryzen Embedded 8845HS. Both processors have empty benchmark arrays, zero recorded wins in their comparison, and an average benchmark score of zero. This means the analysis below relies entirely on the recorded specifications and architectural data, not on measured performance deltas.

The two processors share the same boost clock of 5.10 GHz, which is the only clock speed where they align exactly. The Ryzen AI Embedded P185i starts at a base clock of 2.00 GHz, while the Ryzen Embedded 8845HS begins at 3.80 GHz. This difference in base frequency is substantial, but it must be interpreted carefully. The 8845HS has a higher base clock, which suggests it can sustain higher minimum performance under full load, all else being equal. The P185i, with its lower base clock, likely relies more on boost behavior and power management to reach its performance envelope.

Core and thread counts favor the P185i decisively. The Ryzen AI Embedded P185i uses 12 cores and 24 threads, while the Ryzen Embedded 8845HS uses 8 cores and 16 threads. That is a 50% increase in core count and a 50% increase in thread count for the P185i. In multi-threaded workloads that scale well with core count, the P185i should hold a clear advantage, but without benchmark data, the exact magnitude cannot be quantified. The 8845HS counters with a higher base clock, which helps in lightly threaded tasks or in situations where sustained all-core operation is limited by power or thermal constraints.

Cache configurations show both processors carry 16 MB of L3 cache. The P185i structures its L3 as 16 MB total, while the 8845HS lists its L3 as 16 MB shared. The L1 cache differs per core: the P185i has 80 KB per core, the 8845HS has 64 KB per core. L2 cache is identical at 1 MB per core. The larger L1 per core on the P185i may reduce memory latency for frequently accessed data, but the overall L3 parity means the last-level cache capacity offers no differentiator.

Integrated graphics separate the two clearly. The P185i carries a Radeon 890M, while the 8845HS carries a Radeon 780M. Both are integrated GPUs from AMD, but the 890M is a newer generation part. Without specific graphics benchmark scores in the database, the relative performance must be inferred from the model numbering and generation, which suggests the 890M is positioned above the 780M. The 8845HS also supports DDR5 memory only, while the P185i supports both DDR5 and LPDDR5X. The memory bandwidth figure is identical for both at 89.6 GB/s, and both use dual-channel memory buses.

PCIe lane counts differ. The Ryzen AI Embedded P185i provides 16 lanes of PCIe Gen 4, while the Ryzen Embedded 8845HS provides 20 lanes of PCIe Gen 4. The 8845HS offers 25% more PCIe lanes, which matters for embedded applications that need additional connectivity for storage, networking, or accelerator cards. Both processors support ECC memory, which is a key requirement for embedded and reliability-focused deployments.

Process node and foundry are shared: both are built on TSMC's 4 nm process. The die size differs, with the P185i at 233 mm² and the 8845HS at 178 mm². The larger die on the P185i aligns with its higher core count and newer graphics block. The 8845HS has a recorded transistor count of 25,000 million, while the P185i has no transistor count listed. The P185i also has a larger die area despite having no transistor figure, which indicates a denser or more complex layout, likely due to the additional cores and the newer iGPU.

Thermal design power differs significantly. The P185i has a TDP of 28 watts, while the 8845HS has a TDP of 45 watts. The 8845HS is rated for 60% more power draw. This affects sustained performance, cooling requirements, and system design. The P185i's lower TDP suggests it targets power-constrained embedded platforms, while the 8845HS can use more power to maintain higher base clocks. The base clock difference between the two (2.00 GHz vs 3.80 GHz) is likely tied to this TDP gap, as the 8845HS can dissipate more heat and thus run at a higher minimum frequency.

Release dates place the P185i as a newer product. The P185i has a release date of 2026-02-28, while the 8845HS has a release date of 2024-04-01. That is roughly 23 months between launches. The P185i belongs to the Gorgon Point codename and the generation labeled "Ryzen AI Embedded (Zen 5 / Zen 5c)", while the 8845HS uses the Hawk Point codename and the generation "Ryzen Embedded (Zen 4 (Hawk Point))". The architecture field confirms Zen 5 / Zen 5c for the P185i and Zen 4 for the 8845HS.

The market segment for both is Mobile, and both use the AMD Socket FP8. Both are listed as Active in production status. Neither processor has an unlocked multiplier, and neither has a launch MSRP recorded in the database.

The Verdict

Based strictly on the recorded data, the AMD Ryzen AI Embedded P185i and the AMD Ryzen Embedded 8845HS serve different embedded workloads. The P185i offers 12 cores and 24 threads versus 8 cores and 16 threads, a 50% advantage in parallel execution capacity. It also uses a newer Zen 5 / Zen 5c architecture, a larger L1 cache per core (80 KB vs 64 KB), a newer integrated GPU (Radeon 890M vs Radeon 780M), and broader memory support (DDR5 and LPDDR5X vs DDR5 only). Its TDP is lower at 28 watts versus 45 watts, which makes it suitable for thermally constrained designs.

The 8845HS counters with a much higher base clock of 3.80 GHz versus 2.00 GHz, which indicates stronger single-thread performance at sustained loads. It also provides 20 PCIe Gen 4 lanes versus 16, offering more expansion headroom. The 8845HS has a smaller die (178 mm² vs 233 mm²) and a recorded transistor count of 25,000 million, though the P185i has no such figure for comparison.

The data shows a trade-off: the P185i emphasizes core count, newer architecture, and power efficiency, while the 8845HS emphasizes base frequency, PCIe connectivity, and a more mature platform. Users who prioritize multi-threaded throughput and integrated graphics capability should select the P185i. Users who need higher minimum clock speeds and additional PCIe lanes for peripheral connectivity should select the 8845HS. Without benchmark scores, no further performance ranking is possible.

Both use AMD Socket FP8, dual-channel memory, 89.6 GB/s memory bandwidth, and have no unlocked multiplier.

Architecture Differences

The architectural split is clear from the generation and codename fields. The P185i uses the Gorgon Point codename with a generation labeled "Ryzen AI Embedded (Zen 5 / Zen 5c)", while the 8845HS uses the Hawk Point codename with a generation labeled "Ryzen Embedded (Zen 4 (Hawk Point))". The architecture field confirms Zen 5 / Zen 5c for the P185i and Zen 4 for the 8845HS. Both are built on TSMC's 4 nm process. The P185i has 80 KB of L1 cache per core, while the 8845HS has 64 KB per core. L2 cache is identical at 1 MB per core. L3 cache is 16 MB on both, though the P185i lists it as 16 MB total and the 8845HS lists it as 16 MB shared. The P185i has no listed architecture field beyond the generation, but the 8845HS explicitly lists Zen 4. The P185i's larger die size of 233 mm² versus 178 mm² likely reflects the additional cores and the newer Zen 5 / Zen 5c core complex plus the Radeon 890M graphics block.

Where Each One Wins

The AMD Ryzen AI Embedded P185i wins in scenarios that demand high parallel throughput. Its 12 cores and 24 threads give it a 50% core and thread advantage over the 8845HS. The newer Zen 5 / Zen 5c architecture and larger per-core L1 cache (80 KB vs 64 KB) support this position. The Radeon 890M integrated GPU is a newer generation than the Radeon 780M, so graphics workloads should favor the P185i. The lower TDP of 28 watts makes it suitable for power-sensitive embedded designs. The support for LPDDR5X memory adds flexibility for compact, low-power systems that need high-bandwidth memory in a small footprint.

The AMD Ryzen Embedded 8845HS wins in scenarios that require higher sustained clock speeds and more connectivity. Its base clock of 3.80 GHz is 90% higher than the P185i's 2.00 GHz, which matters for latency-sensitive, lightly threaded tasks. The higher TDP of 45 watts allows for more aggressive power delivery, supporting that base clock. The 20 PCIe Gen 4 lanes, 25% more than the P185i, provide additional bandwidth for storage controllers, network interfaces, or field-programmable gate arrays. The 8845HS also has a smaller die at 178 mm², which may simplify thermal management in some chassis. Its earlier release date of 2024-04-01 means it has been in the market longer, which can indicate broader ecosystem support in embedded applications.
