AMD Ryzen AI Embedded P164i vs AMD Ryzen Embedded 8845HS Comparison

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark scores for the AMD Ryzen AI Embedded P164i versus the AMD Ryzen Embedded 8845HS. Both processors appear with an average benchmark score of 0 and a percentile rank of 50 among all CPUs, indicating that no measured performance data has been captured for either part in the current dataset. Without recorded scores, the comparative benchmark analysis is limited to architectural and specification-based inference rather than direct numerical comparison.

The absence of benchmark results means that neither processor can be declared a winner in any measured workload category. Both the P164i and the 8845HS have identical core and thread counts at 8 cores and 16 threads, so multi-threaded scaling would be expected to behave similarly, but the data does not confirm this. The boost clock difference is notable on paper: the 8845HS reaches 5.10 GHz while the P164i tops out at 5.00 GHz, a 0.10 GHz advantage for the 8845HS. Conversely, the P164i features a lower base clock of 2.00 GHz compared to the 8845HS at 3.80 GHz, which suggests a different power and frequency strategy, but without benchmark numbers, the impact on real-world performance cannot be quantified.

The percentile data places both at 50, which means they sit at the median of the database's CPU distribution. This is unusual for embedded parts with 8 cores, but it reflects the current lack of measured scores rather than actual performance equivalence. The database shows zero wins for either processor in the head-to-head section, confirming that no direct comparison has been recorded.

Given the absence of benchmark figures, the only performance-related conclusions available are derived from the architectural specifications provided. The 8845HS has a larger L3 cache at 16 MB shared versus the P164i's 8 MB, which could benefit cache-sensitive workloads, but this remains speculative without test data. The P164i uses a newer Zen 5 / Zen 5c core design compared to the 8845HS's Zen 4, which typically indicates improved instructions per clock, but again, the database does not include measurements to confirm this advantage.

Architecture Differences

The two processors represent different architectural generations from AMD. The AMD Ryzen AI Embedded P164i is based on the Gorgon Point codename and belongs to the Ryzen AI Embedded generation built on Zen 5 / Zen 5c cores. The AMD Ryzen Embedded 8845HS uses the Hawk Point codename with Zen 4 architecture. Both are fabricated on a 4 nm process at TSMC, but the die sizes differ significantly: the P164i measures 233 mm² while the 8845HS is smaller at 178 mm². The P164i has a transistor count that is not recorded in the database, whereas the 8845HS lists 25,000 million transistors.

Cache hierarchies differ in both L1 and L3. The P164i provides 80 KB of L1 cache per core, and the 8845HS provides 64 KB per core. L2 cache is identical at 1 MB per core. The L3 cache, however, is a major distinction: the P164i has 8 MB total, while the 8845HS has 16 MB shared. This doubling of L3 capacity in the 8845HS could benefit workloads with large working sets that rely on frequent data reuse.

Memory support also diverges. The P164i supports both DDR5 and LPDDR5X memory, while the 8845HS supports only DDR5. Both use a dual-channel memory bus and share the same memory bandwidth of 89.6 GB/s. PCIe lane counts differ: the P164i provides Gen 4 with 16 lanes (CPU only), whereas the 8845HS provides Gen 4 with 20 lanes (CPU only), giving the 8845HS additional PCIe connectivity.

Integrated graphics differ as well. The P164i carries Radeon 880M graphics, while the 8845HS carries Radeon 780M. The database does not provide performance metrics for these iGPUs, so the comparison is limited to naming and architectural generation. The P164i's Zen 5-based graphics core is newer, but no benchmark data confirms its superiority.

The base clock difference is substantial: the P164i runs at 2.00 GHz base, while the 8845HS runs at 3.80 GHz base. Boost clocks are closer, with the 8845HS at 5.10 GHz and the P164i at 5.00 GHz. The TDP difference of 28 watts versus 45 watts indicates that the P164i is designed for lower sustained power draw, likely trading base frequency for efficiency, while the 8845HS can sustain higher clocks at the cost of more power.

Where Each One Wins

Based on the available data, the AMD Ryzen Embedded 8845HS holds advantages in several specification areas. Its higher base clock of 3.80 GHz versus 2.00 GHz suggests stronger sustained performance at default settings, particularly in workloads that do not require boost behavior. The larger L3 cache of 16 MB versus 8 MB provides more on-die storage for frequently accessed data. The higher boost clock of 5.10 GHz gives a marginal peak frequency advantage. The additional PCIe lanes (20 versus 16) allow more expansion devices to be connected directly to the CPU. The earlier release date of 2024-04-01 means this processor has been available in the market for a longer period, which could indicate more mature firmware and ecosystem support.

The AMD Ryzen AI Embedded P164i wins on efficiency-oriented specifications. Its TDP of 28 watts versus 45 watts indicates lower power draw, which is critical for thermally constrained embedded systems. The support for LPDDR5X memory alongside DDR5 provides flexibility in memory selection, particularly for low-power or compact designs. The larger die size of 233 mm² versus 178 mm² suggests a more complex layout, consistent with the newer Zen 5 / Zen 5c core architecture. The newer release date of 2026-03-08 places it as a more recent addition to the market. The Radeon 880M integrated graphics names a newer generation than the Radeon 780M, though no benchmark data confirms its performance.

Neither processor has recorded benchmark wins in the database, so the use-case split is based purely on specification intent. The 8845HS appears oriented toward higher-throughput embedded workloads where power draw is less of a constraint. The P164i appears oriented toward power-sensitive or thermally limited designs that still require 8 cores and 16 threads. The lower base clock of the P164i likely means it relies more heavily on boost behavior for peak performance, while the 8845HS can maintain higher clocks under sustained load.

The Verdict

The recorded data does not provide benchmark scores for either processor, so a direct performance verdict cannot be established from measurements. Instead, the verdict rests on the specification differences documented in the database.

For applications where sustained multi-core throughput is the priority and power consumption is not a limiting factor, the AMD Ryzen Embedded 8845HS is the stronger candidate. Its 3.80 GHz base clock, 5.10 GHz boost clock, and 16 MB L3 cache provide a specification profile that favors continuous, high-frequency operation. The 45 watt TDP indicates that the processor is designed to sustain this level of performance. The additional PCIe lanes also make it suitable for systems that require more expansion capability.

For applications where power efficiency is paramount, the AMD Ryzen AI Embedded P164i is the more appropriate choice. Its 28 watt TDP represents a substantial reduction in thermal output compared to the 8845HS. The support for LPDDR5X memory enables lower-power memory configurations. The newer Zen 5 / Zen 5c architecture, while unmeasured in this database, suggests a more recent design that may deliver better instructions per clock at lower power levels. The 2.00 GHz base clock indicates a design that prioritizes burst performance through boost rather than sustained high-frequency operation.

The release dates provide additional context. The 8845HS entered the market on 2024-04-01, making it an established embedded processor. The P164i is dated 2026-03-08, positioning it as a newer option. Buyers seeking a proven, higher-clock processor with more cache should select the 8845HS. Buyers prioritizing lower power draw, newer architecture, and memory flexibility should select the P164i. The database contains no measured performance numbers, so these conclusions are drawn entirely from the recorded specification data.
