Head-to-Head Benchmarks

The head-to-head benchmark table in the database is empty, meaning no direct comparison scores were recorded between the two processors. However, the Ryzen AI 7 445 has a full set of individual benchmark scores, while the Ryzen Embedded 8640U has none. This makes the comparison one-sided in the recorded data.

The Ryzen AI 7 445 achieves a Cinebench R23 multi-core score of 10590 and a single-core score of 1806. The ratio between these scores indicates strong scaling across its 6 cores and 12 threads. The Cinebench R15 results follow the same pattern: 1723 multi-core and 254 single-core.

In PassMark tests, the Ryzen AI 7 445 records a single-thread score of 3591 (listed twice in the database under slightly different test names) and a multithread score of 18115. The multithread score is roughly five times the single-thread score, which suggests effective utilization of the 12 threads.

The Ryzen AI 7 445 sits at the 79th percentile among all CPUs, with an average benchmark score of 26936. Its 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% higher than the Ryzen AI 7 445. The AMD Ryzen 5 7545U scores 26849, which is 0.3% lower. The AMD Ryzen 7 5700G scores 27051, which is 0.4% higher. The Intel Core i9-9900K scores 27097, which is 0.6% higher. These deltas are all within one percentage point, meaning the Ryzen AI 7 445 lands in a tightly packed performance band around the 26900 to 27100 average score range.

The Ryzen Embedded 8640U has no such rivals listed and no scores to place in context. Its percentile rank of 50 is the default baseline in the database, not a measured result. The database therefore contains no evidence of the Embedded part outperforming the AI part in any workload.

The Verdict

The data supports a straightforward selection based on measured performance. The AMD Ryzen AI 7 445 is the only one of the two with recorded benchmark results, and those results place it at the 79th percentile of all CPUs. It shows strong single-thread performance with a Cinebench R23 single-core score of 1806 and a PassMark single-thread score of 3591. It shows strong multi-thread performance with a Cinebench R23 multi-core score of 10590 and a PassMark multithread score of 18115. Its average benchmark score of 26936 places it within 0.6% of the Intel Core i9-9900K and within 0.3% of the AMD Ryzen 5 7545U, indicating it trades blows with established desktop and mobile parts from prior generations.

The AMD Ryzen Embedded 8640U offers attributes that are not measured in the database but are recorded in its specifications. It has a higher base clock of 3.50 GHz and a higher boost clock of 4.90 GHz, both exceeding the Ryzen AI 7 445. It has 16 MB of shared L3 cache versus 4 MB, a fourfold difference. It provides 20 PCIe Gen 4 lanes versus 14. It has a larger physical footprint with 25,000 million transistors and a 178 mm² die size. These specifications suggest the Embedded part is designed for connectivity and sustained operation rather than peak benchmark performance.

For workloads where the database has measurements, the Ryzen AI 7 445 is the clear choice. Any task that relies on single-thread speed or multi-thread throughput will favor it based on the recorded scores. The near-tie with the Intel Core i7-1370P (0.1% delta) and the AMD Ryzen 5 7545U (0.3% delta) shows it competes effectively with a wide range of mid-to-high-end processors.

For workloads where the database has no measurements, the Ryzen Embedded 8640U remains an unverified option. Its higher clocks and larger L3 cache could translate into real advantages in cache-sensitive or lightly threaded embedded workloads, but the database contains no scores to confirm this. Its 20 PCIe Gen 4 lanes and DDR5 support make it suitable for systems requiring more expansion, but performance cannot be quantified from the available data.

The verdict is therefore conditional on the use case. If the selection depends on measured compute performance, the Ryzen AI 7 445 wins on every recorded benchmark. If the selection depends on connectivity, cache capacity, or clock speed, the Ryzen Embedded 8640U has the specification advantage, but no benchmark data exists to validate its real-world performance.
