Head-to-Head Benchmarks

The largest AMD victory comes in random string sorting, where the Ryzen AI 7 450G scores 42663 against the Intel's 32777, a 30.2% advantage. Extended instructions follow with a 29.4% lead (28223 versus 21806). Data compression shows an 18.8% edge (402831 versus 339133). Single-thread performance is 9% higher (4309 versus 3955). Multithreaded performance is 3.9% ahead (30422 versus 29271). Data encryption is a narrow 3% win (18937 versus 18385).

The Intel Core 7 253PE's biggest win is in prime number finding, where it scores 138 against the AMD's 87, a 37% advantage. Physics simulation shows a 22% lead (1845 versus 1440). Floating-point math is 21.3% ahead (80870 versus 63683). Integer math is 12.6% ahead (114158 versus 99732).

These results reveal a clear pattern. The AMD processor excels in memory-access-intensive and latency-sensitive workloads like compression, sorting, encryption, and single-thread execution. The Intel processor dominates in pure arithmetic throughput, particularly in workloads that can utilize its 10 cores, 20 threads, and large 33 MB L3 cache for parallel number crunching.

The average benchmark score difference is stark: the AMD Ryzen AI 7 450G averages 63331 across all recorded benchmarks, while the Intel Core 7 253PE averages 40557. This gap is largely explained by the AMD part's massive wins in data compression and random string sorting, which are heavy contributors to the average. The Intel part's Cinebench scores (R15 multicore 2507, R20 multicore 10449, R23 multicore 24880) are not directly comparable to the AMD's PassMark scores, as the database does not list Cinebench results for the AMD processor.
