The Verdict

The benchmark record points to two distinct usage profiles. The AMD Ryzen 7 8745HX is the stronger overall performer, with a 13.6 percent higher average benchmark score and wins in 9 of 11 categories. It is the clear choice for workloads that demand sustained multi-threaded throughput, encryption, physics simulation, and integer math. Its 55 W TDP and unlocked multiplier indicate a design aimed at performance-first mobile systems, and the data supports that positioning.

The AMD Ryzen AI Embedded P164, by contrast, wins only the single-thread tests, and by a modest 3.7 percent margin. Its 28 W TDP, locked multiplier, and ECC memory support point to an embedded role where power efficiency and reliability matter more than peak performance. The single-thread advantage indicates that the Zen 5 architecture brings real IPC gains, but those gains do not translate into overall dominance because the lower base clock and smaller L3 cache hold back multi-threaded results.

For users choosing between these two processors, the decision hinges on workload mix. The Ryzen 7 8745HX is the better fit for compute-heavy mobile applications, while the Ryzen AI Embedded P164 suits embedded deployments that prioritize lower power draw and ECC memory. The data does not suggest that one chip is universally superior; it shows two different design trade-offs. The Ryzen 7 8745HX trades power and size for performance, while the Ryzen AI Embedded P164 trades performance for efficiency and feature set.
