AMD Ryzen AI Embedded P164 vs AMD Ryzen Embedded 8845HS Comparison

Head-to-Head Benchmarks

The database does not contain a direct head-to-head benchmark comparison between the AMD Ryzen AI Embedded P164 and the AMD Ryzen Embedded 8845HS, and the 8845HS has no recorded benchmark scores in its profile. The P164, however, has a full set of PassMark measurements. Its average benchmark score is 52,901, which places it at the 91st percentile of all CPUs in the database. The 8845HS, by contrast, sits at the 50th percentile with an average score of 0, indicating that no performance data has been captured for that part.

Because the 8845HS lacks recorded scores, the most productive way to interpret the P164's results is through its nearest rivals. The P164's average score of 52,901 is nearly identical to the AMD Ryzen 5 9500F, which scores 52,873, a delta of just 0.1%. It also trades blows with the Intel Xeon 634 (52,974, delta -0.1%), the AMD EPYC 7313P (53,206, delta -0.6%), and the AMD Ryzen 9 7900X (53,288, delta -0.7%). These deltas are all within a single percentage point, indicating that the P164 performs in the same tier as those established desktop and server parts.

Looking at the P164's individual workload scores, the data reveals a processor that excels in compression and encryption tasks. Its PassMark data compression score is 327,891, a figure that dwarfs its other results. Data encryption scores 16,055, and extended instructions reach 24,193. Integer math scores 87,940, while floating point math lands at 55,799. The multithread score is 25,889, and single-thread performance registers at 4,029. Random string sorting produces 34,801, physics scores 1,210, and find prime numbers scores just 71.

The lack of any benchmark entries for the 8845HS means that no direct wins can be assigned to either processor. The database records zero wins for each part in the head-to-head comparison. This is a case where the measurement infrastructure has captured data for one part and not the other, so the analysis must rely on architectural specifications rather than comparative test results.

Architecture Differences

The two processors share several foundational traits but diverge in key architectural areas. Both are manufactured by AMD, both use TSMC's 4 nm process node, both use the AMD Socket FP8, and both are classified as mobile market segments with active production status. Both also support ECC memory, dual-channel memory buses, and DDR5 memory. Neither has an unlocked multiplier.

The most significant architectural difference is the core design generation. The P164 uses the Gorgon Point codename with a generation described as "Ryzen AI Embedded (Zen 5 / Zen 5c)." The 8845HS uses the Hawk Point codename with a generation of "Ryzen Embedded (Zen 4 (Hawk Point))." This means the P164 is built on a newer Zen 5 architecture family, while the 8845HS relies on the previous Zen 4 design.

Cache configurations differ substantially. The P164 has 80 KB of L1 cache per core, 1 MB of L2 cache per core, and 8 MB of L3 cache. The 8845HS has 64 KB of L1 cache per core, also 1 MB of L2 cache per core, but a much larger 16 MB of shared L3 cache. The 8845HS therefore offers double the L3 capacity, which can benefit workloads with large working sets, while the P164 has larger per-core L1 cache.

Die size and transistor counts also separate the two. The P164 has a die size of 233 mm², while the 8845HS is smaller at 178 mm². The 8845HS has a recorded transistor count of 25,000 million, while the P164's transistor count is not listed in the database. The larger die on the P164 is notable given that it uses a smaller L3 cache, suggesting the Zen 5 / Zen 5c core layout occupies more silicon area.

Clock speeds tell a more nuanced story. The P164 has a base clock of 2.00 GHz and a boost clock of 5.00 GHz. The 8845HS has a significantly higher base clock of 3.80 GHz and a slightly higher boost of 5.10 GHz. The 8845HS also carries a higher TDP of 45 watts, compared to the P164's 28 watts. The higher base clock and TDP of the 8845HS suggest it can sustain higher all-core frequencies under load, while the P164 is tuned for lower power consumption with a still-competitive boost ceiling.

Memory support shows a minor divergence. The P164 supports both DDR5 and LPDDR5X memory, while the 8845HS lists only DDR5. Both have a memory bandwidth of 89.6 GB/s. PCIe lanes differ as well: the P164 offers Gen 4 with 16 lanes (CPU only), while the 8845HS offers Gen 4 with 20 lanes (CPU only). The 8845HS provides four additional CPU-attached PCIe lanes.

Integrated graphics differ between the two. The P164 uses the Radeon 880M, while the 8845HS uses the Radeon 780M. The 880M is the newer graphics block, consistent with the P164's newer architecture generation.

Release timing is also distinct. The P164 has a release date of 2026-03-08, while the 8845HS was released on 2024-04-01. Neither part has a recorded launch MSRP in the database.

Where Each One Wins

Without direct benchmark data for the 8845HS, the wins must be inferred from specification differences. The 8845HS holds advantages in raw clock speed and cache capacity. Its 3.80 GHz base clock is 1.8 GHz higher than the P164's 2.00 GHz base, and its 5.10 GHz boost is 0.1 GHz higher. For workloads that are latency-sensitive or that depend on single-thread responsiveness, the higher base clock suggests the 8845HS can maintain higher sustained frequencies without relying on boost conditions. The 16 MB of shared L3 cache, double the P164's 8 MB, gives the 8845HS a clear edge for workloads that repeatedly access large data structures, such as database workloads or certain scientific computing patterns.

The 8845HS also has more PCIe lanes, 20 versus 16, which supports more attached devices or higher-bandwidth I/O configurations. Its 45 W TDP, while higher, indicates the platform is designed to feed more power to the cores, which can translate to higher sustained all-core throughput in thermally unconstrained environments.

The P164 wins in areas tied to its newer architecture and efficiency. Its Zen 5 / Zen 5c generation is newer than the Zen 4 design in the 8845HS. The P164's 28 W TDP is 17 W lower, making it the more power-efficient choice for embedded systems where thermal budgets are tight. The P164 also supports LPDDR5X memory in addition to DDR5, which can enable lower-power memory configurations or higher-bandwidth designs depending on implementation. Its larger die size of 233 mm² versus 178 mm² suggests a more complex core layout, and its Radeon 880M integrated graphics represent a newer generation than the 780M.

The P164's benchmark results, while not directly comparable to the 8845HS, place it at the 91st percentile of all CPUs, a strong showing. The 8845HS's 50th percentile ranking, while based on no recorded scores, at least positions it in the database's middle tier. The P164's recorded average score of 52,901 is substantial, and its data compression score of 327,891 indicates a processor that handles compression workloads exceptionally well. For embedded use cases involving encryption, the P164's 16,055 encryption score and 24,193 extended instructions score suggest capable performance.

The practical split is therefore: the 8845HS for sustained all-core compute with larger caches and more I/O, the P164 for power-constrained embedded designs that benefit from a newer core architecture and newer integrated graphics.

The Verdict

The data presents an incomplete comparison because the 8845HS has no recorded benchmark scores. What the database does show is that the P164 is a fully measured processor with a 91st percentile ranking and an average score of 52,901, placing it alongside the AMD Ryzen 5 9500F, Intel Xeon 634, AMD EPYC 7313P, and AMD Ryzen 9 7900X within a 1% performance band. The 8845HS, with its 50th percentile ranking and no scores, cannot be matched against that data.

From a specification standpoint, the choice breaks down by use case. The 8845HS is the higher-clocked part with a 3.80 GHz base frequency, a 5.10 GHz boost, 16 MB of L3 cache, 20 PCIe lanes, and a 45 W TDP. It suits embedded designs that prioritize sustained multi-core throughput, larger cache residency, and more I/O expansion, and where the platform can accommodate its higher power draw. Its 178 mm² die and 25,000 million transistors also make it the smaller, more transistor-dense design.

The P164 uses the newer Zen 5 / Zen 5c architecture on a 233 mm² die, runs at a 28 W TDP, supports LPDDR5X in addition to DDR5, and carries the Radeon 880M. It suits power-constrained embedded systems that need the latest core architecture, lower thermal output, and a newer integrated graphics block. Its recorded benchmark strength in data compression (327,891) and encryption (16,055) indicates specific workload advantages, though those numbers cannot be compared directly to the 8845HS without matching data.

Buyers who need verified performance numbers should select based on the P164's recorded results. Buyers who need maximum sustained clocks and cache capacity on paper should look to the 8845HS. The database cannot declare an overall winner because the 8845HS has no measurement record, so the verdict rests on the P164's complete benchmark profile versus the 8845HS's specification advantages.
