AMD Ryzen AI 7 450 vs Intel Core 7 251E Comparison

# AMD Ryzen AI 7 450 vs Intel Core 7 251E

The AMD Ryzen AI 7 450 and Intel Core 7 251E occupy distinct positions in the processor landscape, with the former built for mobile platforms and the latter designed for desktop systems. The recorded data shows a dramatic split in benchmark coverage: the AMD part has 15 measured performance scores across Cinebench and Passmark suites, while the Intel part currently has no recorded benchmark results in the database. This asymmetry shapes the analysis, allowing a detailed examination of the AMD processor's capabilities while limiting direct quantitative comparison for the Intel processor. The AMD Ryzen AI 7 450 sits at the 87th percentile among all CPUs tracked in the database, whereas the Intel Core 7 251E rests at the 50th percentile, a gap that reflects both performance and the availability of test data.

Where Each One Wins

The AMD Ryzen AI 7 450 demonstrates strength across a wide range of workloads based on its 15 recorded benchmark scores. In single-threaded performance, the processor delivers a Cinebench R23 single-core score of 2038 and a Passmark single-thread score of 3901, placing it in a competitive position for applications that depend on responsive single-core execution. The multi-core results are equally substantial, with a Cinebench R23 multi-core score of 18316 and a Passmark multithread score of 26350, showing that the 8-core, 16-thread configuration handles heavily parallel workloads effectively.

The Intel Core 7 251E presents a different profile entirely. With 24 cores and 32 threads, the processor has a structural advantage in raw thread count, yet the database contains no benchmark scores for it. The processor achieves a 50th percentile ranking among all CPUs, but this ranking appears to be based on limited or incomplete data rather than measured performance. The Intel part targets the desktop segment with a 65 W TDP, while the AMD part is a mobile processor with a 28 W TDP, so the comparison is not one of direct competitors but rather of two processors aimed at different platform types and power envelopes.

The AMD Ryzen AI 7 450 wins in data encryption, scoring 16247 in Passmark's encryption test, and in extended instruction workloads, scoring 22400 in Passmark's extended instructions test. These results suggest strong cryptographic and SIMD capability. The Intel Core 7 251E, lacking measured scores, cannot claim victories in any recorded workload, but its 36 MB of shared L3 cache and 32 threads indicate potential advantages in cache-sensitive and highly threaded scenarios that the data cannot currently confirm.

Architecture Differences

The architectural gap between these two processors is substantial. The AMD Ryzen AI 7 450 uses the Zen 5 architecture on a 4 nm TSMC process, with the Gorgon Point codename and a 195 mm² die size. It belongs to the Ryzen AI 400 generation, which combines Zen 5 and Zen 5c cores. The 8 cores and 16 threads operate at a base clock of 2.00 GHz and a boost clock of 5.10 GHz. The cache hierarchy consists of 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of L3 cache.

The Intel Core 7 251E uses the Bartlett Lake codename on a 10 nm Intel process, with a 257 mm² die size. It belongs to the Core 7 generation and features 24 cores and 32 threads at a base clock of 2.10 GHz and a boost clock of 5.60 GHz. The cache hierarchy is notably different: 80 KB of L1 per core, 2 MB of L2 per core, and a much larger 36 MB of shared L3 cache. The Intel processor supports both DDR4 and DDR5 memory, while the AMD processor supports DDR5 and LPDDR5X.

Memory bandwidth is identical at 89.6 GB/s for both processors, and both use dual-channel memory buses. Both support ECC memory. PCIe connectivity differs, with the AMD part using Gen 4 with 16 CPU lanes and the Intel part using Gen 5 with 16 CPU lanes. The integrated graphics also differ: the AMD processor includes Radeon 860M graphics, while the Intel processor includes UHD Graphics 770.

Head-to-Head Benchmarks

The head-to-head benchmark data in the database is empty, meaning no direct comparison scores exist between the AMD Ryzen AI 7 450 and the Intel Core 7 251E. However, the AMD processor's individual benchmark results provide a complete picture of its performance profile. The Cinebench R15 multi-core score of 2713 and single-core score of 215 establish a baseline for older rendering workloads. The Cinebench R23 results, 18316 multi-core and 2038 single-core, show a strong ratio between multi-threaded and single-threaded performance.

Passmark results for the AMD processor cover a broad range of operations. The data compression score of 315906 is particularly high, indicating excellent performance in compression algorithms. Data encryption at 16247 and extended instructions at 22400 both show robust processing capability. The floating point math score of 54447 and integer math score of 88531 demonstrate strong arithmetic throughput. The find prime numbers score of 89 and random string sorting score of 35648 add further detail to the performance picture. The physics score of 1578 and multithread score of 26350 complete the Passmark suite.

The average benchmark score for the AMD processor is 39485. This places it in close proximity to several rivals in the database. The AMD Ryzen 7 PRO 8840HS averages 39603, which is 0.3% higher than the Ryzen AI 7 450. The AMD Ryzen 7 PRO 8845HS averages 39325, which is 0.4% lower. The AMD EPYC 4245P averages 39215, which is 0.7% lower. The AMD Ryzen 7 9800X3D averages 39768, which is 0.7% higher. These small deltas indicate that the Ryzen AI 7 450 performs in the same tier as these established processors, despite being a mobile part.

The Intel Core 7 251E has no benchmark scores and an average benchmark score of zero, so no direct performance comparisons can be made. The processor's 50th percentile ranking suggests it sits in the middle of the database's tracked CPUs, but this ranking lacks the supporting data that would allow a detailed interpretation.

The Verdict

For users selecting between these two processors, the decision hinges on platform and data availability. The AMD Ryzen AI 7 450 is a mobile processor with a 28 W TDP, designed for laptops and portable systems. Its 15 recorded benchmarks show strong performance across single-threaded and multi-threaded workloads, with particularly notable results in data compression and integer math. The 87th percentile ranking among all CPUs indicates that it outperforms the majority of processors in the database.

The Intel Core 7 251E is a desktop processor with a 65 W TDP, designed for desktop systems on Intel Socket 1700. It offers 24 cores and 32 threads, which is three times the core count and double the thread count of the AMD processor. The 36 MB of shared L3 cache is more than four times larger than the AMD part's 8 MB. However, the complete absence of benchmark scores for the Intel processor means that its actual performance cannot be verified from the database.

The data supports the AMD Ryzen AI 7 450 as the better-documented processor with proven performance. The Intel Core 7 251E offers structural advantages in core count, thread count, and cache size, but without measured benchmarks, those advantages remain theoretical. The AMD processor's nearest rivals, all within 0.7% of its average score, include both mobile and desktop parts, showing that the Ryzen AI 7 450 competes effectively across segments. The choice between these two processors should be guided by platform requirements: mobile users should select the AMD part, while desktop users considering the Intel part should note that its performance data is not yet available in the database.
