AMD Ryzen 7 7745HX vs AMD Ryzen 7 PRO 7730U: comparison
Comparison of AMD Ryzen 7 7745HX and AMD Ryzen 7 PRO 7730U: key differences and a full specification table.
Key differences
AMD Ryzen 7 7745HX has a higher base clock (3.6 GHz vs 2 GHz), a higher maximum clock (5.1 GHz vs 4.5 GHz), a larger L3 cache (32 MB vs 16 MB) and a finer process node (5 nm vs 7 nm).
At the same time, AMD Ryzen 7 PRO 7730U has a lower TDP (15 W vs 55 W).
Both processors match on: core count (8), thread count (16), maximum memory size (64 GB), memory channels (2).
These are specification values: they show differences between the models but do not determine a performance winner. For a specific workload, rely on independent benchmarks.
