AMD Ryzen AI 5 430 vs Intel Core 7 251E Comparison

Head-to-Head Benchmarks

The direct comparison between the AMD Ryzen AI 5 430 and the Intel Core 7 251E is limited by the available database records. The AMD processor has a full set of benchmark scores recorded, while the Intel Core 7 251E currently has no benchmark entries in the database. This absence of recorded data for the Intel part makes a direct, test-by-test comparison impossible. However, the database does provide a meaningful aggregate metric for the AMD chip: its average benchmark score of 19,617 places it at the 73rd percentile among all CPUs. The Intel Core 7 251E, with no recorded scores, sits at the 50th percentile by default, a placeholder value until measurements are populated.

The AMD Ryzen AI 5 430 demonstrates its strongest results in the Cinebench suite. In Cinebench R23 multi-core, it records a score of 8,130, while its single-core result in the same test reaches 1,797. The older Cinebench R15 workload shows a multi-core score of 1,195 and a single-core score of 269. These figures indicate a balanced execution core design that scales reasonably from single-threaded to multi-threaded workloads, though the absolute numbers reflect the processor's modest 4-core, 8-thread configuration.

PassMark results for the AMD chip reveal where its architectural strengths lie. The integer math test produces a score of 39,637, while floating point math reaches 27,193. Extended instructions score 11,455. Data compression achieves 158,912, and data encryption records 7,591. Random string sorting delivers 16,623. The multi-thread score is 13,320, and single-thread performance registers 3,683. Physics testing yields 726, and the prime number search workload scores 44. These results show a processor that excels in compression and integer workloads, with encryption and prime number tasks being comparatively weaker areas.

The nearest rivals for the AMD Ryzen AI 5 430, as recorded in the database, provide context for its aggregate standing. The AMD Ryzen 5 5500 posts an average score of 19,593, which is 0.1% behind the Ryzen AI 5 430. The Intel Core i5-12500 scores 19,668, putting it 0.3% ahead. The Intel Core i5-11600KF records 19,723, a 0.5% advantage. The Intel Core i7-10700F scores 19,499, trailing by 0.6%. These deltas are small, indicating that the Ryzen AI 5 430 competes directly with a cluster of established desktop processors from both AMD and Intel despite its mobile-oriented design.

Because the Intel Core 7 251E lacks recorded benchmark scores, there are no head-to-head wins to assign in either direction. The database shows zero wins for each processor in this pairing. The analysis must therefore rely on the architectural and specification differences to characterize expected performance, while the only concrete measured data belongs to the AMD part.

The Verdict

The recorded data supports a straightforward conclusion: the AMD Ryzen AI 5 430 is the only processor in this pairing with measured performance data, and its 73rd percentile standing among all CPUs indicates a competent mid-range performer. Its average benchmark score of 19,617 aligns closely with several established desktop chips, including the AMD Ryzen 5 5500 and Intel Core i5-12500, both of which sit within 0.3% of its score. Buyers seeking a mobile processor with confirmed benchmark results can rely on these figures.

The Intel Core 7 251E, by contrast, has no measured scores in the database. Its 50th percentile is a default value, not a reflection of tested performance. The chip does bring a significantly higher core count, 24 cores and 32 threads, compared to the AMD part's 4 cores and 8 threads. It also boosts to 5.60 GHz versus 4.50 GHz for the AMD chip, and its L3 cache is 36 MB shared, compared to 4 MB on the AMD side. These specifications suggest a processor designed for heavily threaded desktop workloads, but without benchmark data, the database cannot confirm how those specifications translate into measured performance.

The data indicates that the AMD Ryzen AI 5 430 suits users who need a validated, efficient mobile processor with a compact core layout. The Intel Core 7 251E targets desktop users who prioritize core count and thread throughput, but its lack of recorded benchmarks means any performance claims remain unverified. The choice between the two depends on whether the user values confirmed measurements or raw specification advantages.
