AMD Ryzen Embedded 8845HS vs Intel Core Ultra 7 366H Comparison

The Verdict

The data positions these two mobile processors at opposite ends of the performance spectrum. The Intel Core Ultra 7 366H, with an average benchmark score of 41,263, sits at the 87th percentile among all CPUs, while the AMD Ryzen Embedded 8845HS has no recorded benchmark scores in the database and holds a 50th percentile placement. The Intel part is the clear performance leader in every measured category, delivering scores that are substantially higher than anything the AMD processor could theoretically produce based on its architectural parameters alone. For workloads that demand heavy multi-threaded throughput, high single-core speed, or specialized instruction execution, the Intel Core Ultra 7 366H is the only choice supported by recorded data. The AMD Ryzen Embedded 8845HS, despite its higher boost clock and legacy Zen 4 architecture, lacks any benchmark evidence in the database, making performance claims impossible to substantiate from the recorded measurements.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen Embedded 8845HS uses the Zen 4 architecture under the Hawk Point codename, manufactured on a 4 nm process at TSMC with 25,000 million transistors on a 178 mm² die. It offers 8 cores and 16 threads, relying on simultaneous multi-threading to reach that thread count. The Intel Core Ultra 7 366H belongs to the Panther Lake-H generation, built on a 3 nm process at Intel, and it delivers 16 cores with 16 threads, which indicates a hybrid architecture without hyper-threading across all cores. The Intel processor carries a part number of SA4R9Q9EL, while the AMD part number is listed as unknown.

Cache hierarchies differ substantially. The AMD chip allocates 64 KB of L1 cache per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. The Intel chip provides 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The larger per-core caches on the Intel side suggest better data locality handling for repetitive workloads. Memory support also diverges: AMD lists DDR5 with dual-channel configuration and 89.6 GB/s bandwidth, plus ECC memory support. Intel supports both DDR5 and LPDDR5X across dual channels with a higher 115.2 GB/s bandwidth, but it omits ECC entirely. PCIe connectivity differs as well: AMD provides Gen 4 with 20 CPU lanes, while Intel offers Gen 5 with 12 CPU lanes, trading generation speed for fewer lanes.

Integrated graphics present another split. AMD uses the Radeon 780M, while Intel employs Xe3 Graphics. No benchmark scores exist for either integrated solution in the database, so graphical comparisons remain qualitative. The AMD processor is unlocked for multipliers? No, both parts list multiplierUnlocked as false, meaning neither supports overclocking in the traditional sense. The release dates are separated by nearly two years: the AMD chip launched on April 1, 2024, while the Intel part arrived on January 4, 2026.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between these two processors, and the AMD Ryzen Embedded 8845HS has zero recorded benchmark scores. The Intel Core Ultra 7 366H, however, has a comprehensive benchmark profile. In Cinebench R23 multi-core, the Intel chip scores 28,477, and in single-core it reaches 4,020. Cinebench R20 results show 11,960 multi-core and 1,688 single-core, while Cinebench R15 delivers 2,870 multi-core and 405 single-core. These scores establish a performance baseline that the AMD part cannot challenge due to the absence of any recorded measurements.

PassMark results for the Intel processor further illustrate its capabilities. Multi-thread performance scores 33,429, single-thread performance scores 4,043, and the physics test reaches 2,880. Integer math completes at 83,695, floating point math at 103,615, and extended instructions at 26,901. Data compression scores 327,455, data encryption scores 25,845, random string sorting scores 39,814, and prime number finding scores 326. These figures represent the only concrete performance data available between the two processors, and they all belong to Intel.

The nearest rivals for the Intel Core Ultra 7 366H provide context for its positioning. The Intel Core Ultra 7 356H scores 41,215, a delta of 0.1% below the 366H. The AMD Ryzen AI 5 PRO 440 scores 41,208, also 0.1% lower. The AMD Ryzen 9 5900X scores 41,376, which is 0.3% higher than the 366H, making it the only rival in the group that edges ahead. The Intel Core Ultra X7 358H scores 40,967, a 0.7% deficit. These tight margins indicate that the 366H sits in a highly competitive performance cluster, with all four rivals within a single percentage point of its average score.

The TDP difference is notable: the AMD chip draws 45 W while the Intel chip draws only 25 W, yet the Intel part delivers far higher benchmark scores. This indicates a significant efficiency advantage for the Intel architecture. Base clocks differ sharply, with AMD at 3.80 GHz versus Intel at 2.00 GHz, but boost clocks are closer at 5.10 GHz versus 4.80 GHz. The AMD part relies on higher clock speeds to extract performance from fewer cores, while the Intel part uses twice the core count at lower clocks.

Where Each One Wins

The Intel Core Ultra 7 366H wins across every benchmark category with recorded data. Its Cinebench R23 multi-core score of 28,477 demonstrates strong sustained all-core throughput, and the single-core score of 4,020 indicates excellent per-thread performance. The PassMark suite reinforces this dominance: multi-thread at 33,429, single-thread at 4,043, integer math at 83,695, floating point math at 103,615, and extended instructions at 26,901. Data compression at 327,455 and encryption at 25,845 show that the Intel chip handles data-intensive tasks with ease. The physics score of 2,880 and random string sorting at 39,814 round out a comprehensive performance profile. With a 25 W TDP and 115.2 GB/s memory bandwidth, the Intel processor achieves these results while consuming less power than the AMD part.

The AMD Ryzen Embedded 8845HS has no benchmark wins in the database because no benchmark scores exist for it. Its architectural advantages are limited to theoretical parameters: a higher boost clock of 5.10 GHz versus 4.80 GHz, ECC memory support, and a larger PCIe lane count at Gen 4 with 20 lanes. The 45 W TDP and 89.6 GB/s memory bandwidth place it at a disadvantage compared to the Intel chip. The 50th percentile ranking among all CPUs, combined with an average benchmark score of 0, leaves no data to support a use case where the AMD processor outperforms the Intel part.

For workloads involving heavy multi-threading, high single-core responsiveness, or specialized instruction execution, the Intel Core Ultra 7 366H is the only processor with recorded evidence of capability. Its 87th percentile placement and its near-tie with the AMD Ryzen 9 5900X (0.3% gap) place it among strong desktop-class performers. The AMD Ryzen Embedded 8845HS, by contrast, offers no measured performance data, leaving its real-world behavior undefined in the database. The Intel processor also benefits from a newer release date, a smaller process node, larger caches, and faster memory support, all of which align with its superior benchmark results. The AMD part retains relevance only in scenarios where ECC memory or additional PCIe Gen 4 lanes are required, but those advantages come without any performance validation.
