AMD Ryzen AI 7 445 vs AMD Ryzen Embedded 8840U Comparison

The AMD Ryzen AI 7 445 and the AMD Ryzen Embedded 8840U are both 28 W mobile processors from AMD, but they serve different design philosophies. The Ryzen AI 7 445 is a 6-core, 12-thread part built on the Zen 5 architecture, while the Ryzen Embedded 8840U is an 8-core, 16-thread part using the older Zen 4 architecture. The recorded data shows that the Ryzen AI 7 445 has a complete set of benchmark results, placing it in the 79th percentile of all CPUs, while the Ryzen Embedded 8840U has no recorded benchmark scores in the database, placing it in the 50th percentile with an average benchmark score of zero. This asymmetry means the analysis must rely on architectural differences and the measured performance of the AI 7 445, with extrapolation for the 8840U based on its specifications.

Architecture Differences

The two processors diverge significantly in their underlying architecture. The AMD Ryzen AI 7 445 is based on the Zen 5 architecture, using the Gorgon Point codename, and belongs to the Ryzen AI 400 generation, which combines Zen 5 and Zen 5c cores. The AMD Ryzen Embedded 8840U uses the Zen 4 architecture with the Hawk Point codename, part of the Ryzen Embedded series. Both are fabricated on a 4 nm process at TSMC, but the 8840U has published transistor and die size data: 25,000 million transistors on a 178 mm² die. The Ryzen AI 7 445 does not have transistor or die size data recorded.

The cache hierarchy shows a notable difference. The Ryzen AI 7 445 has 80 KB of L1 cache per core and 1 MB of L2 cache per core, with a total of 4 MB of L3 cache. The Ryzen Embedded 8840U has 64 KB of L1 cache per core and 1 MB of L2 cache per core, but its L3 cache is 16 MB and shared across all cores. This gives the 8840U a substantial 12 MB advantage in L3 capacity, which can benefit workloads with large working sets or frequent data sharing between cores.

Both processors share the same AMD Socket FP8, a 28 W TDP, dual-channel memory support, and ECC memory capability. The memory support differs slightly: the Ryzen AI 7 445 supports both DDR5 and LPDDR5X, while the Ryzen Embedded 8840U supports DDR5 only. The PCIe configuration also differs. The Ryzen AI 7 445 provides Gen 4 with 14 lanes (CPU only), while the Ryzen Embedded 8840U provides Gen 4 with 20 lanes (CPU only), a 6-lane advantage for the embedded part.

The integrated graphics differ as well. The Ryzen AI 7 445 uses the Radeon 840M, while the Ryzen Embedded 8840U uses the Radeon 780M. The production status for both is listed as active, and neither has an unlocked multiplier. The release dates are separated by roughly 21 months, with the Ryzen Embedded 8840U released on 2024-04-01 and the Ryzen AI 7 445 released on 2026-01-04.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Ryzen AI 7 445 and the AMD Ryzen Embedded 8840U. The wins counter for both processors is zero in the head-to-head comparison. Consequently, the performance analysis for the Ryzen AI 7 445 is based on its own recorded benchmark scores and its position relative to other CPUs in the database.

The Ryzen AI 7 445 has a comprehensive benchmark suite. In Cinebench R23, it scores 10590 in multicore and 1806 in single-core. In the older Cinebench R15, it scores 1723 in multicore and 254 in single-core. PassMark results include a multithread score of 18115, a single-thread score of 3591, integer math at 58332, floating point math at 39362, data compression at 215812, data encryption at 10519, extended instructions at 15826, find prime numbers at 56, physics at 976, and random string sorting at 23488.

Its average benchmark score is 26936, placing it in the 79th percentile of all CPUs. The nearest rivals in the database provide context for this score. The Intel Core i7-1370P has an average score of 26900, which is 0.1% lower than the Ryzen AI 7 445. The AMD Ryzen 5 7545U scores 26849, 0.3% lower. The AMD Ryzen 7 5700G scores 27051, which is 0.4% higher than the Ryzen AI 7 445. The Intel Core i9-9900K scores 27097, 0.6% higher. These tight margins indicate that the Ryzen AI 7 445 sits in a competitive performance band, effectively matching a desktop Core i9-9900K from several generations prior.

Since the Ryzen Embedded 8840U has no benchmark scores, its performance cannot be directly compared. However, its architectural advantages are clear: 8 cores versus 6, 16 threads versus 12, a boost clock of 5.10 GHz versus 4.60 GHz, and 16 MB of L3 cache versus 4 MB. These specifications suggest that the 8840U would have a significant advantage in heavily threaded workloads, while the Zen 5 architecture of the Ryzen AI 7 445 might provide an instruction-per-clock advantage in single-threaded tasks. The database does not provide measurements to confirm this, so no definitive performance conclusion is possible.

The Verdict

The data indicates that the AMD Ryzen AI 7 445 is a measured performer, with a 79th percentile ranking and an average benchmark score of 26936. Its nearest rivals, all within 0.6% of its score, confirm that it delivers performance comparable to established desktop processors like the Intel Core i9-9900K and the AMD Ryzen 7 5700G. For users selecting a processor from the mobile segment, the Ryzen AI 7 445 provides a validated performance profile.

The AMD Ryzen Embedded 8840U, by contrast, has no recorded benchmark data. Its average benchmark score is zero, and its percentile ranking of 50 is the default baseline. The only quantitative information available is its specification sheet, which shows more cores, more threads, higher clocks, and more cache than the Ryzen AI 7 445. In a purely specification-based comparison, the 8840U appears to have the raw resources for better multithreaded performance, but the database cannot confirm this without measurements.

The Ryzen AI 7 445 is the correct choice for applications where verified performance data is required. Its benchmark results span Cinebench and PassMark tests, covering both single-threaded and multithreaded workloads. The 8840U is appropriate for embedded designs where the higher core count, higher clocks, and larger L3 cache are the primary selection criteria, and where the absence of benchmark data is acceptable. The 8840U also offers more PCIe lanes, which may be relevant for embedded systems with multiple expansion devices.

Where Each One Wins

The AMD Ryzen AI 7 445 wins in the database's measured performance metrics because it is the only one of the two with benchmark results. Its Cinebench R23 multicore score of 10590 and single-core score of 1806 provide a concrete performance baseline. Its PassMark multithread score of 18115 and single-thread score of 3591 further establish its capabilities. For any workload where a verified performance number is required, the Ryzen AI 7 445 is the only option with supporting data.

The AMD Ryzen Embedded 8840U wins on specification-driven advantages. Its 8 cores and 16 threads give it a 33% core advantage and a 33% thread advantage over the 6-core, 12-thread Ryzen AI 7 445. Its boost clock of 5.10 GHz is 0.50 GHz higher, and its base clock of 3.30 GHz is 1.30 GHz higher. The 16 MB of L3 cache is four times the 4 MB on the Ryzen AI 7 445. The 20 PCIe Gen 4 lanes exceed the 14 lanes on the Ryzen AI 7 445 by 6 lanes. These specifications make the 8840U the stronger candidate for multithreaded workloads, embedded systems with heavy I/O requirements, and scenarios where the larger cache can reduce memory latency.

For single-threaded performance, the Ryzen AI 7 445 has the newer Zen 5 architecture and a higher L1 cache per core at 80 KB versus 64 KB, but its lower boost clock of 4.60 GHz versus 5.10 GHz may offset that advantage. Without benchmark data for the 8840U, the database cannot determine which processor has superior single-thread performance. The Ryzen AI 7 445 also supports LPDDR5X memory in addition to DDR5, which may benefit power-sensitive mobile designs. The Ryzen Embedded 8840U, with its earlier release date and established production status, represents a known quantity for embedded deployments.

In terms of integrated graphics, the Radeon 840M on the Ryzen AI 7 445 and the Radeon 780M on the Ryzen Embedded 8840U are different models, but the database provides no performance scores for either. The Ryzen AI 7 445 has the advantage of a newer release date, while the Ryzen Embedded 8840U has the advantage of higher core counts and clocks. The choice between them depends on whether the user prioritizes measured benchmark data or raw specification headroom. The data supports the Ryzen AI 7 445 for validated performance and the Ryzen Embedded 8840U for specification-driven multithreaded and I/O-heavy use cases.
