AMD Ryzen AI 7 PRO 450 vs Intel Core 9 273PTE Comparison

The AMD Ryzen AI 7 PRO 450 and the Intel Core 9 273PTE present two fundamentally different approaches to processing, one tailored for mobile efficiency and the other for desktop throughput. The benchmark data reveals a clear split, with the AMD chip winning 9 of 15 head-to-head tests while the Intel chip takes the remaining 6, but the nature of those victories matters more than the count.

Where Each One Wins

The AMD Ryzen AI 7 PRO 450 establishes its dominance in tasks that rely on rapid data manipulation and instruction-level parallelism. Its most significant victory comes in PassMark extended instructions, where it scores 20778 against Intel's 15952, a 30.3% advantage. This suggests the Zen 5 architecture handles complex instruction sets with greater efficiency. The AMD chip also wins PassMark single-thread performance with a score of 3955 versus 3433, a 15.2% lead, which indicates strong per-core execution despite its lower boost clock.

Data compression and sorting workloads also favor the AMD processor. It scores 294298 in PassMark data compression, beating the Intel part's 258704 by 13.8%. Random string sorting shows an 11.6% advantage, with scores of 32344 and 28973 respectively. These results point to a processor that excels in database operations, file archiving, and other memory-intensive data movement tasks. The AMD chip also edges ahead in integer math (86227 vs 82411, a 4.6% lead), multithread performance (24779 vs 24054, a 3% lead), and data encryption (14925 vs 14253, a 4.7% lead).

The Intel Core 9 273PTE counters with wins in raw compute-bound workloads. Its PassMark physics score of 1917 trumps the AMD's 1337 by 30.3%, indicating superior performance in simulation and physics engine calculations. The Intel chip also leads in floating point math, scoring 60673 against 52971, a 12.7% advantage. Prime number finding shows the largest gap, with Intel scoring 142 versus AMD's 84, a 40.8% margin that suggests a strong advantage in certain cryptographic and mathematical workloads.

Cinebench results split between the two processors. The AMD chip wins Cinebench R15 multicore with 2457 versus 2060, a 19.3% margin, but the Intel chip wins Cinebench R23 multicore with 20445 versus 16054, a 21.5% advantage. Intel also takes both single-core Cinebench tests, leading R23 single-core by 30.4% (2886 vs 2010) and R15 single-core by 24.1% (290 vs 220).

The Verdict

The data indicates that the AMD Ryzen AI 7 PRO 450 is the stronger choice for general productivity and data-centric workloads. Its lead in single-thread PassMark, extended instructions, and data compression makes it well suited for office applications, web browsing, and content creation tasks that involve large files. The processor's 85th percentile ranking among all CPUs, compared to Intel's 82nd, reinforces this position. The AMD chip also delivers this performance within a 28 W TDP, making it appropriate for thin-and-light mobile systems.

The Intel Core 9 273PTE is the better option for compute-heavy scientific, mathematical, and physics-based applications. Its commanding leads in prime number finding and physics benchmarks, combined with its Cinebench R23 multicore victory, show a processor that can sustain heavy computational loads. The 45 W TDP and desktop Socket 1700 platform indicate it is designed for systems where power draw is less of a constraint.

Users who prioritize single-core responsiveness in legacy benchmarks will find the Intel chip compelling, as its Cinebench R23 single-core score is 30.4% higher. However, the AMD chip's PassMark single-thread score is 15.2% higher, which complicates the picture. The database shows that the AMD processor is generally more balanced, while the Intel processor excels in specific niches.

Head-to-Head Benchmarks

The largest single margin in the dataset belongs to the Intel Core 9 273PTE in PassMark find prime numbers, where it scores 142 against the AMD's 84, a 40.8% difference. This result stands out because it is the only test where the Intel chip more than doubles its competitor's score. The next largest Intel victory is a 30.4% lead in Cinebench R23 single-core, followed by a 30.3% lead in PassMark physics.

The AMD Ryzen AI 7 PRO 450 matches that 30.3% figure with its own win in PassMark extended instructions, scoring 20778 against 15952. The AMD chip's 19.3% lead in Cinebench R15 multicore is notable because it reverses the result seen in Cinebench R23 multicore, where Intel leads by 21.5%. This discrepancy suggests the two processors respond differently to the workload scaling between Cinebench versions.

PassMark single-thread and singlethread tests both show the AMD chip winning 3955 to 3433, a 15.2% margin. This is a significant result because it contradicts the Cinebench single-core results, which favor Intel by 24.1% and 30.4%. The divergence implies the processors have different strengths in single-threaded execution depending on the instruction mix.

The AMD chip's 13.8% lead in data compression and 11.6% lead in random string sorting round out its strongest categories. The Intel chip's 12.7% lead in floating point math and the AMD's narrower wins in encryption, integer math, and multithread performance complete the picture of a split decision.
