AMD Ryzen Embedded 8840U vs Intel Core Ultra 7 366H Comparison

Head-to-Head Benchmarks

The database records no shared benchmark results between the AMD Ryzen Embedded 8840U and the Intel Core Ultra 7 366H. The Intel part has an extensive set of recorded scores, while the AMD entry has no benchmark entries at all. Direct comparison of performance must therefore rely on the Intel processor's absolute scores and its position relative to other CPUs in the database.

The Intel Core Ultra 7 366H delivers a Cinebench R23 multi-core score of 28,477 and a single-core score of 4,020. In Cinebench R20, it records 11,960 multi-core and 1,688 single-core. The older R15 test shows 2,870 multi-core and 405 single-core. PassMark results include a multi-thread score of 33,429, single-thread of 4,043, integer math at 83,695, floating point math at 103,615, and extended instructions at 26,901. Data compression scores 327,455, data encryption 25,845, physics 2,880, random string sorting 39,814, and prime number finding 326.

The Intel chip sits at the 87th percentile of all CPUs in the database, with an average benchmark score of 41,263. Its nearest rivals are tightly clustered. The Intel Core Ultra 7 356H scores 41,215, a delta of 0.1 percent. The AMD Ryzen AI 5 PRO 440 also scores 41,208, another 0.1 percent delta. The AMD Ryzen 9 5900X scores 41,376, which is 0.3 percent higher than the 366H. The Intel Core Ultra X7 358H scores 40,967, 0.7 percent lower. These deltas are small, indicating the 366H performs essentially on par with its immediate competitors in aggregate benchmark terms.

Given the absence of any head-to-head benchmark data, the AMD Ryzen Embedded 8840U cannot be quantitatively compared to the Intel part. The database shows zero wins for either processor in direct tests. Any assessment of the AMD chip must rely on its architectural specifications alone, without numerical performance claims.

Where Each One Wins

For the Intel Core Ultra 7 366H, the recorded data shows strengths across multiple workload types. The Cinebench multi-core results, especially the R23 score of 28,477, indicate strong sustained throughput in rendering and similar parallel tasks. The PassMark multi-thread score of 33,429 reinforces this picture. Single-thread performance is also solid, with the R23 single-core score of 4,020 and PassMark single-thread of 4,043 showing capable per-core execution.

The PassMark sub-tests reveal specific strengths. Integer math at 83,695 and floating point math at 103,615 suggest balanced arithmetic capability. Data compression at 327,455 is particularly strong, indicating efficient handling of compression workloads. Data encryption at 25,845 and extended instructions at 26,901 show support for specialized instruction sets. Random string sorting at 39,814 and physics at 2,880 round out the profile.

The AMD Ryzen Embedded 8840U has no recorded benchmark wins. The database lists zero wins for either processor in head-to-head tests. Without measured scores, the AMD chip's performance characteristics cannot be established from the data. Its specifications suggest it targets similar mobile workloads, but no empirical evidence exists in the database to confirm or deny this.

Architecture Differences

The AMD Ryzen Embedded 8840U uses the Zen 4 architecture under the Hawk Point codename, built on a 4 nm process at TSMC. It has 8 cores and 16 threads, with a base clock of 3.30 GHz and boost clock of 5.10 GHz. The chip contains 25,000 million transistors on a 178 mm² die. Cache is organized as 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. It supports DDR5 memory on a dual-channel bus with 89.6 GB/s bandwidth. ECC memory is supported. The integrated graphics is Radeon 780M. PCIe is Gen 4 with 20 lanes from the CPU. The socket is AMD Socket FP8. The thermal design power is 28 watts. Production status is active, with a release date of April 2024.

The Intel Core Ultra 7 366H uses the Panther Lake architecture, built on a 3 nm process at Intel. It has 16 cores and 16 threads, with a base clock of 2.00 GHz and boost clock of 4.80 GHz. Cache is organized as 192 KB L1 per core, 2.5 MB L2 per core, and 18 MB shared L3. It supports DDR5 and LPDDR5X memory on a dual-channel bus with 115.2 GB/s bandwidth. ECC memory is not supported. The integrated graphics is Intel Xe3 Graphics. PCIe is Gen 5 with 12 lanes from the CPU. The socket is Intel BGA 2540. The thermal design power is 25 watts. Production status is active, with a release date of January 2026. The part number is SA4R9Q9EL.

Several differences stand out. The Intel part has twice the core count but the same thread count, meaning it uses a hybrid design without simultaneous multithreading, while the AMD chip uses 8 cores with 16 threads via SMT. The Intel chip has a lower base clock but a modestly lower boost clock. The Intel L1 and L2 caches are larger per core, and the L3 is slightly larger. Memory bandwidth is higher on the Intel part at 115.2 GB/s versus 89.6 GB/s. The Intel process node is smaller at 3 nm versus 4 nm. PCIe generation differs, with Intel at Gen 5 and AMD at Gen 4, though the AMD chip has more lanes. ECC memory is available only on the AMD part. The Intel chip supports both DDR5 and LPDDR5X, while the AMD chip lists DDR5 only.

The Verdict

The recorded data supports the Intel Core Ultra 7 366H as the only processor with measured performance. Its 87th percentile ranking and average score of 41,263 place it among capable mobile processors. The nearest rival deltas, all within 0.7 percent, show it performs essentially identically to its closest competitors. The Cinebench R23 multi-core score of 28,477 and PassMark multi-thread of 33,429 indicate strong parallel throughput. Single-core results are also respectable.

The AMD Ryzen Embedded 8840U cannot be evaluated on performance from the database. No benchmark scores exist for it. Its percentile ranking is 50, but this is not backed by any measured average score. The chip's architectural specifications, including 8 cores with SMT, Zen 4, and a 5.10 GHz boost clock, suggest it may compete in similar mobile segments, but the data provides no confirmation.

For users seeking a processor with verified performance, the Intel Core Ultra 7 366H is the choice supported by the database. For those who prioritize ECC memory support or the specific AMD platform, the Ryzen Embedded 8840U offers those features, but performance remains unquantified. The Intel chip also provides higher memory bandwidth and a smaller process node. The AMD chip has more PCIe lanes and a higher boost clock on paper. Without measurements, the AMD option is a specification-based pick, not a performance-based one.
