AMD Ryzen 7 8745HX vs Intel Core Ultra X7 368H Comparison

The AMD Ryzen 7 8745HX and Intel Core Ultra X7 368H are two mobile processors aimed at different priorities. The AMD chip, part of the 8000 series, uses a Zen 4 design on a 5 nm node, while Intel's Core Ultra Series 3 uses Panther Lake architecture on a 3 nm node. The recorded benchmark data shows a clear split: the AMD Ryzen 7 8745HX wins 4 of the 11 head-to-head tests, while the Intel Core Ultra X7 368H wins 7. The AMD chip delivers higher average performance in its strongest areas, but the Intel chip counters with notable wins in several compute-heavy workloads, including a significant advantage in floating-point math and physics simulations. The database places the AMD part in the 92nd percentile of all CPUs, while the Intel part sits in the 87th percentile, indicating the AMD has a higher overall ranking despite the Intel winning more individual tests in this comparison.

The Verdict

The data suggests two distinct user profiles. For workloads that rely heavily on integer math, data compression, and random string sorting, the AMD Ryzen 7 8745HX is the clear choice. Its wins in these areas are substantial, with a 13.9% lead in integer math and a 16.8% lead in random string sorting over the Intel chip. The AMD part also shows a 16.2% advantage in data compression, making it the stronger option for tasks like archiving, database operations, and certain types of content processing.

For users whose tasks involve floating-point calculations, physics simulations, prime number finding, or encryption, the Intel Core Ultra X7 368H is the better pick. The Intel chip dominates in floating-point math, scoring 105681 versus 61972 for the AMD, a 41.4% difference. It also leads by 41.2% in the physics test and by 50.5% in the find prime numbers test. These results point toward scientific computing, rendering, or any workload that stresses FPU performance. Additionally, the Intel part has a slight edge in single-thread performance, scoring 4005 versus 3879, a 3.1% lead, which can benefit lightly threaded applications.

The multithread score is close, with the Intel chip winning 32956 versus 31517, a 4.4% margin. This means for purely parallel workloads that are not dominated by floating-point or integer math, the two processors perform similarly, and the choice should be guided by the specific application mix.
