AMD Ryzen AI Embedded P174i vs AMD Ryzen Embedded 8845HS Comparison

Head-to-Head Benchmarks

The database contains no recorded benchmark scores, no head-to-head benchmark entries, and no win counts for either processor. The average benchmark score for both the AMD Ryzen AI Embedded P174i and the AMD Ryzen Embedded 8845HS is zero, with both CPUs sitting at the 50th percentile among all CPUs in the database. This absence of measured performance data means any direct numerical comparison of processing speed, multi-threaded throughput, or integrated graphics capability is not possible from the recorded information.

What the data does provide is a structural comparison. The P174i uses 10 cores and 20 threads, while the 8845HS uses 8 cores and 16 threads. The P174i has a base clock of 2.00 GHz and a boost clock of 5.00 GHz. The 8845HS has a base clock of 3.80 GHz and a boost clock of 5.10 GHz. The 8845HS holds a 0.10 GHz advantage in boost frequency, which could translate to higher single-thread performance in lightly threaded workloads, though no empirical score confirms this. Conversely, the P174i offers two additional physical cores and four additional threads, which typically benefits heavily parallel workloads such as compilation or rendering. Without benchmark results, the magnitude of these advantages remains unquantified.

Both processors share the same socket, AMD Socket FP8, and both use a dual-channel memory bus with identical memory bandwidth of 89.6 GB/s. Both support ECC memory. The P174i supports DDR5 and LPDDR5X memory, while the 8845HS supports DDR5 only. Both are built on TSMC's 4 nm process node. The P174i uses the Gorgon Point codename with a Zen 5 / Zen 5c hybrid core arrangement, while the 8845HS uses the Hawk Point codename with Zen 4 cores. The P174i integrates a Radeon 880M GPU, and the 8845HS integrates a Radeon 780M GPU. The die size for the P174i is 233 mm², and the 8845HS die size is 178 mm². The 8845HS has a listed transistor count of 25,000 million, while the P174i does not have a transistor count in the database.

The thermal design power differs substantially. The P174i has a TDP of 28 watts, and the 8845HS has a TDP of 45 watts. This 17 watt difference indicates the P174i is designed for lower power envelopes, which may affect sustained performance in thermally constrained systems. The 8845HS, with its higher TDP, can potentially sustain higher clocks under load, but again, no benchmark data confirms this behavior.

PCIe lane counts also differ. The P174i provides Gen 4 with 16 lanes for the CPU, while the 8845HS provides Gen 4 with 20 lanes for the CPU. The 8845HS offers four additional PCIe lanes, which could support more expansion devices or additional storage controllers.

The release dates are recorded. The 8845HS was released on 2024-04-01, and the P174i was released on 2026-02-28. The P174i is a later release, coming almost two years after the 8845HS.

Architecture Differences

The two processors diverge significantly in their core architectures. The AMD Ryzen AI Embedded P174i is built on the Gorgon Point codename and uses a hybrid core arrangement of Zen 5 and Zen 5c cores. This represents a newer generation design compared to the AMD Ryzen Embedded 8845HS, which uses the Hawk Point codename and solely employs Zen 4 architecture cores. The P174i's 10 cores and 20 threads likely combine higher-performance Zen 5 cores with more efficient Zen 5c cores, a design strategy that balances throughput and power efficiency. The 8845HS uses 8 cores and 16 threads, all based on the older Zen 4 architecture.

The process node for both is identical at 4 nm from TSMC. However, the die size differs: the P174i measures 233 mm², while the 8845HS measures 178 mm². The larger die on the P174i accommodates the additional cores and the newer architecture. The 8845HS has a recorded transistor count of 25,000 million, while the P174i does not have a transistor count listed in the database.

Cache hierarchies are similar in capacity but differ in per-core allocation. The P174i has 80 KB of L1 cache per core, while the 8845HS has 64 KB of L1 cache per core. Both have 1 MB of L2 cache per core. L3 cache is 16 MB for the P174i, and the 8845HS also has 16 MB of shared L3 cache. The per-core L1 difference favors the P174i by 16 KB per core. The P174i's L3 cache is not labeled as shared, while the 8845HS explicitly lists its L3 as shared.

The integrated graphics differ between the two. The P174i includes a Radeon 880M GPU, and the 8845HS includes a Radeon 780M GPU. Both are integrated into the processor package, and no benchmark scores for these GPUs are recorded.

The memory controller also differs. The P174i supports both DDR5 and LPDDR5X, enabling lower-power memory configurations. The 8845HS supports DDR5 only. Both maintain a dual-channel memory bus with 89.6 GB/s bandwidth. The PCIe implementation differs as well: the P174i provides Gen 4 with 16 CPU lanes, and the 8845HS provides Gen 4 with 20 CPU lanes.

Where Each One Wins

Based on the recorded data, the AMD Ryzen AI Embedded P174i holds advantages in several areas. It has more cores and threads, with 10 cores and 20 threads versus 8 cores and 16 threads on the 8845HS. This suggests better performance in multi-threaded workloads where parallel processing is key. The P174i also has a larger L1 cache per core at 80 KB versus 64 KB, which could reduce memory latency in some operations. Its memory controller supports LPDDR5X in addition to DDR5, offering flexibility for power-sensitive designs. The P174i's lower TDP of 28 watts versus 45 watts indicates it can operate in thermally constrained environments or with smaller cooling solutions. Its integrated Radeon 880M is a newer GPU generation than the Radeon 780M. The P174i also has a newer release date, coming in 2026-02-28 versus 2024-04-01 for the 8845HS.

The AMD Ryzen Embedded 8845HS counters with its own set of advantages. It has a higher base clock of 3.80 GHz versus 2.00 GHz, and a higher boost clock of 5.10 GHz versus 5.00 GHz. Higher clock speeds typically benefit single-threaded and lightly threaded workloads. The 8845HS has a higher TDP of 45 watts, which allows for more sustained power draw and potentially more consistent performance under continuous load. It provides more PCIe lanes, 20 versus 16, which supports more expansion devices. The 8845HS has a smaller die size at 178 mm² versus 233 mm², and it has a listed transistor count of 25,000 million, which the P174i lacks in the database. Its Zen 4 architecture, while older, is a known quantity with a longer track record.

The Verdict

The data presents two processors with complementary strengths. The AMD Ryzen AI Embedded P174i offers a higher core and thread count, a lower TPD of 28 watts, a newer Zen 5 / Zen 5c architecture, LPDDR5X memory support, and a newer integrated GPU. The AMD Ryzen Embedded 8845HS offers higher clock speeds, a higher TDP of 45 watts, more PCIe lanes, and a smaller die size.

For workloads that scale with core count, such as parallel compilation, virtualization, or multi-threaded server tasks, the P174i's 10 cores and 20 threads provide a structural advantage. Its lower power envelope also suits embedded systems with limited cooling or battery power. The support for LPDDR5X memory further reinforces its suitability for power-conscious designs.

For workloads that depend on single-thread performance or higher sustained clocks, the 8845HS's base clock of 3.80 GHz and boost clock of 5.10 GHz give it an edge. The higher TDP of 45 watts means it can draw more power to maintain performance. The additional four PCIe lanes provide more connectivity options for embedded systems requiring multiple controllers or accelerators.

The absence of benchmark scores means no empirical performance verdict can be issued. The database shows zero wins for either processor, zero average benchmark scores, and identical 50th percentile rankings. The selection between the two depends entirely on the specific requirements of the embedded application. The P174i targets scenarios where core count and power efficiency are priorities. The 8845HS targets scenarios where clock speed and expansion capacity are priorities. Neither processor can be declared a performance winner based on the recorded data.
