AMD Ryzen Embedded 8840U vs Intel Core Ultra 5 225T Comparison

Head-to-Head Benchmarks

The recorded database contains a complete benchmark profile for the Intel Core Ultra 5 225T, while the AMD Ryzen Embedded 8840U has no benchmark entries in our measurements. This asymmetry means the comparison relies entirely on the Intel processor's scores against its nearest rivals, which include the AMD Ryzen 5 7640HS and AMD Ryzen 7 7736U. The Core Ultra 5 225T posts an average benchmark score of 30468, placing it in the 82nd percentile of all CPUs in the database. That score is 0.2% above the Intel Core i9-11980HK (30422), 0.3% above the AMD Ryzen 5 7640HS (30390), and 0.3% above the AMD Ryzen 7 7736U (30364). It trails the Intel Core i5-13600H (30548) by 0.3%.

Looking at the individual workload results, the Core Ultra 5 225T shows a strong split between single-threaded and multi-threaded performance. In Cinebench R23, it scores 21971 in multi-core and 3101 in single-core. The single-core result corresponds to a boost clock of 4.90 GHz, while the multi-core result reflects the processor's 10 cores and 10 threads. The R20 run shows 9227 multi-core and 1302 single-core, and the older R15 test produces 2214 multi-core and 312 single-core. These scores scale consistently across the three Cinebench versions, indicating stable frequency behavior under sustained load.

PassMark results add further detail. The multi-thread score is 25358, while the single-thread score is 4348. Integer math reaches 59543, floating point math reaches 82751, and extended instructions hit 20083. Data compression scores 233998, data encryption scores 18289, and random string sorting scores 28774. The physics test records 2053, and the prime number search returns 284. The gap between the multi-thread score and the sum of individual math workloads confirms that the 10-core, 10-thread configuration prioritizes parallel throughput in tasks that scale linearly, but the lack of hyperthreading means the thread count equals the core count, which limits scaling in lightly threaded workloads that rely on extra logical processors.

Since the Ryzen Embedded 8840U has no benchmark data in the database, its performance cannot be directly quantified against the Core Ultra 5 225T. However, the Ryzen chip's architecture places it in a different performance class. The 8840U uses 8 cores and 16 threads with a boost clock of 5.10 GHz, which is 0.20 GHz higher than the Intel part's 4.90 GHz. The AMD processor also supports simultaneous multithreading, giving it 16 threads versus the Intel part's 10 threads. In purely threaded workloads, that thread advantage could offset the Intel chip's higher multi-core scores in some scenarios, but without recorded benchmarks for the AMD part, the database cannot confirm this.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen Embedded 8840U is built on Zen 4 architecture with the Hawk Point codename, part of the Ryzen Embedded 8000 series. It uses a 4 nm process node from TSMC, with 25,000 million transistors on a 178 mm² die. The Intel Core Ultra 5 225T uses Arrow Lake architecture with the Arrow Lake-S codename, part of the Core Ultra Series 2. It is built on a 3 nm process node, also from TSMC, with 17,800 million transistors on a 243 mm² die. The Intel die is larger despite fewer transistors, which reflects differences in the physical layout of the compute tiles and the integrated graphics.

Cache hierarchies differ substantially. The AMD chip has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The Intel chip has 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 20 MB of shared L3 cache. Per-core L2 is three times larger on the Intel part, which helps with data locality in single-threaded workloads. The AMD part has more L3 total per core when accounting for its 8-core layout, but the Intel part has a larger absolute L3 pool at 20 MB versus 16 MB.

Memory support also differs. Both support DDR5 and dual-channel memory, but the Intel part has a higher memory bandwidth at 102.4 GB/s versus 89.6 GB/s for the AMD part. The AMD chip supports ECC memory, while the Intel chip does not. This makes the Ryzen Embedded part more suitable for memory-sensitive embedded workloads where error correction is required. PCIe connectivity differs as well: the AMD chip provides Gen 4 with 20 lanes (CPU only), while the Intel chip provides Gen 5 with 20 lanes (CPU only). The newer PCIe generation on the Intel part doubles the per-lane bandwidth, which matters for storage and accelerator cards.

Integrated graphics differ significantly. The AMD Ryzen Embedded 8840U carries a Radeon 780M, which is a full-featured integrated GPU. The Intel Core Ultra 5 225T carries an Arc Xe-LPG Graphics 16EU, which is a smaller execution unit configuration. The 780M has historically delivered higher graphics throughput in embedded and mobile parts, but the database does not include graphics benchmarks for either processor. The market segments also differ: the AMD part is classified as Mobile, while the Intel part is classified as Desktop. The Intel part uses Socket 1851, while the AMD part uses AMD Socket FP8. Both are active production parts, but the Intel part was released on 2024-12-31, while the AMD part was released on 2024-04-01.

The Verdict

Based strictly on recorded data, the Intel Core Ultra 5 225T is the only processor of the two with measurable benchmark results. Its average benchmark score of 30468 places it in the 82nd percentile of all CPUs, and its nearest rivals all sit within 0.3% of its score. That cluster of results indicates the Core Ultra 5 225T performs in line with upper-midrange laptop and mobile processors from both AMD and Intel, despite being a desktop part. The 10-core, 10-thread configuration with a 4.90 GHz boost clock delivers competitive single-threaded performance, as shown by the 3101 Cinebench R23 single-core score and the 4348 PassMark single-thread score.

For buyers considering the AMD Ryzen Embedded 8840U, the lack of benchmark data makes a direct verdict impossible. The AMD part has architectural advantages that the data can support qualitatively: 16 threads versus 10, a 5.10 GHz boost clock versus 4.90 GHz, ECC memory support, and a Radeon 780M integrated GPU. The Intel part counters with a larger L3 cache, higher memory bandwidth, PCIe Gen 5, and a smaller manufacturing node. The choice between these two should rest on workload requirements rather than raw benchmark comparisons, since the database cannot quantify the AMD part's performance.

Where Each One Wins

The Intel Core Ultra 5 225T wins in scenarios where the recorded benchmarks apply. Its 21971 Cinebench R23 multi-core score and 25358 PassMark multi-thread score indicate strong parallel throughput for its 10-core configuration. The 4.90 GHz boost clock and 3101 Cinebench R23 single-core score show competitive single-threaded performance. The larger 20 MB L3 cache and 102.4 GB/s memory bandwidth benefit workloads with large working sets or high memory traffic. The PCIe Gen 5 support provides double the per-lane bandwidth of the AMD part's Gen 4, which helps with high-speed NVMe storage and accelerator cards. The 3 nm process node and 65 W TDP suggest a higher power envelope for sustained desktop operation.

The AMD Ryzen Embedded 8840U wins in workload categories that its architecture specifically targets. The 16 threads from 8 cores with simultaneous multithreading provide better scaling in heavily threaded server or embedded workloads that can use more than 10 logical processors. The 5.10 GHz boost clock gives it a frequency advantage in lightly threaded tasks, though the database has no benchmark to confirm this in practice. The ECC memory support makes it suitable for data integrity applications where uncorrected errors are unacceptable. The 28 W TDP indicates much lower power consumption, which matters for embedded and mobile deployments where thermal and power budgets are tight. The Radeon 780M integrated GPU is a more capable graphics solution than the Arc Xe-LPG Graphics 16EU, though no graphics benchmarks are recorded. The smaller 178 mm² die and 25,000 million transistors on a 4 nm node reflect a denser, more power-efficient design aimed at embedded use cases rather than raw throughput.
