AMD Ryzen AI 7 450 vs AMD Ryzen Embedded 8640U Comparison

Head-to-Head Benchmarks

The recorded data for the AMD Ryzen AI 7 450 shows a processor with substantial multi-threaded capability. In Cinebench R23, the multicore score reaches 18,316 points, while the single-core score sits at 2,038 points. The Cinebench R15 results follow a similar pattern, with a multicore score of 2,713 and a single-core score of 215. These figures place the Ryzen AI 7 450 in the 87th percentile of all CPUs in the database, indicating that it outperforms the vast majority of recorded processors.

The Ryzen AI 7 450 also delivers strong results in PassMark tests. Its multithread score is 26,350, while the single-thread score is 3,901. Integer math performance reaches 88,531, and floating point math scores 54,447. Data encryption processes at 16,247, while data compression achieves 315,906. Extended instruction workloads score 22,400, and the processor handles random string sorting at 35,648. Physics calculations score 1,578, and prime number finding scores 89.

The database does not contain benchmark results for the AMD Ryzen Embedded 8640U. Its average benchmark score is recorded as zero, and it holds no nearest rival entries. This absence of recorded performance data means direct head-to-head comparisons cannot be drawn from the measurements. The Ryzen AI 7 450, by contrast, has a complete set of benchmark scores across multiple test suites, allowing for percentile placement and rival comparisons.

When the Ryzen AI 7 450 is compared to its nearest rivals in the database, the results show a tightly clustered field. The AMD Ryzen 7 PRO 8840HS averages 39,603 points, which is 0.3% higher than the Ryzen AI 7 450's average of 39,485. The AMD Ryzen 7 PRO 8845HS averages 39,325 points, placing it 0.4% behind. The AMD EPYC 4245P averages 39,215 points, a 0.7% deficit. The AMD Ryzen 7 9800X3D averages 39,768 points, which is 0.7% ahead. These deltas are narrow, showing that the Ryzen AI 7 450 operates within a performance envelope very close to these established processors.

The Verdict

The data indicates a clear split between the two processors. The AMD Ryzen AI 7 450 is a fully benchmarked mobile processor with an 87th percentile standing across all CPUs. Its average benchmark score of 39,485 places it in the company of high-end desktop and mobile parts like the Ryzen 7 9800X3D and the Ryzen 7 PRO 8845HS, with deltas under one percent in either direction.

The AMD Ryzen Embedded 8640U, however, has no recorded benchmark scores in the database. Its percentile rank is 50, and its average score is zero. This is not a statement about its real-world performance, but about the available data. The database cannot verify its capabilities through any measured tests. For users who rely on the database for performance validation, the Ryzen AI 7 450 is the only one of the two with substantiated results.

From the recorded figures, the Ryzen AI 7 450 delivers multicore performance that would suit demanding workloads, given its 18,316 Cinebench R23 multicore score and its 26,350 PassMark multithread score. The Ryzen Embedded 8640U, with no scores, cannot be assessed in this manner. The verdict from the data is straightforward: the Ryzen AI 7 450 has measurable, competitive performance, while the Ryzen Embedded 8640U lacks any database-verified performance metrics.

Where Each One Wins

The AMD Ryzen AI 7 450 wins in every category where recorded data exists. Its benchmark scores cover Cinebench R15 and R23, both single and multicore, as well as a full suite of PassMark tests. The Cinebench R23 multicore score of 18,316 indicates strong parallel processing capability, suitable for rendering, compilation, or other heavily threaded workloads. The single-core score of 2,038 suggests competent per-thread performance for everyday tasks and lighter applications.

The PassMark data reinforces this. A multithread score of 26,350 and an integer math score of 88,531 point to solid general-purpose compute. The data compression score of 315,906 is particularly high, indicating efficient handling of compression workloads. The floating point score of 54,447 supports scientific or financial calculations. The extended instructions score of 22,400 shows proficiency with modern instruction sets.

The AMD Ryzen Embedded 8640U has no benchmark wins because it has no benchmark data. The database contains zero entries for this processor. Its 50th percentile rank is a default value, not a measured result. In practical terms, the Ryzen Embedded 8640U cannot be declared a winner in any database-recorded test.

The Ryzen AI 7 450 also wins on connectivity for general use, with 16 PCIe Gen 4 lanes versus 20 on the Embedded part. The AI part supports LPDDR5X memory, which the Embedded part does not. The AI part has a higher boost clock and more cores. The Embedded part has a higher base clock and more L3 cache, but without benchmark data, those advantages cannot be quantified in performance terms.
