The data places AMD in a slightly higher performance tier overall, with its average score closer to desktop-class parts than to Intel's mobile-derived figures.

The Verdict

The benchmark results indicate that the AMD Ryzen AI 7 450 is the stronger all-around processor in this pairing. Its average benchmark score of 39485 exceeds Intel's 34962 by a substantial margin, and it wins 10 of 15 direct tests. The AMD part leads in compression, encryption, extended instructions, physics, random string sorting, prime number finding, PassMark multi-thread, and PassMark single-thread, while also holding a commanding Cinebench R15 multi-core advantage.

The Intel Core 7 253PTE is not without merit. Its Cinebench R23 multi-core win at 21276 versus 18316 shows that in certain sustained multi-threaded rendering workloads, the Intel design pulls ahead. The R23 single-core result of 3003 versus 2038 is a decisive 32.1% margin, and integer and floating point math both favor Intel by large percentages. These wins matter for workloads that are dominated by raw integer throughput or single-core responsiveness.

The database shows that the AMD processor is the better choice for general-purpose computing, memory-sensitive tasks, and mixed workloads. The Intel processor is the better choice specifically for single-core-bound applications and integer-heavy processing. The percentile ranks reinforce this: AMD at 87th percentile versus Intel at 84th, with AMD's nearest rivals including the Ryzen 7 9800X3D, a desktop flagship part. Intel's nearest rivals are mobile HX-series chips and a Xeon, indicating its performance class sits lower in the overall distribution.

Where Each One Wins

The AMD Ryzen AI 7 450 wins in 10 of the 15 recorded head-to-head tests. Its strengths are concentrated in compression, encryption, extended instruction throughput, physics simulation, random string sorting, prime number finding, PassMark multi-thread, and PassMark single-thread. The largest margins come in extended instructions (31%), Cinebench R15 multi-core (26.5%), random string sorting (26.3%), physics (19.7%), and data compression (14.5%). These results suggest the AMD part handles mixed integer and floating point workloads efficiently, particularly where instruction-level parallelism and memory access patterns matter. The 4 nm process and lower 28 W TDP also indicate better energy efficiency per unit of work, though the database does not record power draw directly.

The Intel Core 7 253PTE wins in 5 tests: Cinebench R23 single-core, Cinebench R15 single-core, Cinebench R23 multi-core, integer math, and floating point math. The single-core wins are the most decisive in the entire comparison, with margins of 32.1% and 28.8%. The integer math win at 25.9% and floating point win at 19% show raw arithmetic throughput is a clear Intel strength. The Cinebench R23 multi-core win at 13.9% demonstrates that in sustained rendering workloads, the 10-core, 20-thread Intel design with 33 MB of L3 cache can outpace the AMD part despite the latter's higher average score. The 5.40 GHz boost clock and 45 W TDP contribute to these peak performance results.

For use-case selection, the data supports the following split. The AMD Ryzen AI 7 450 is the better choice for general productivity, data compression tasks, encryption workloads, physics calculations, and any application that benefits from high PassMark multi-thread scores. The Intel Core 7 253PTE is the better choice for single-core-bound applications, integer-heavy computation, and Cinebench-style rendering that scales with its larger core count and cache. The aggregate average score favors AMD by roughly 12.9%, placing it at the 87th percentile versus Intel's 84th.
