Intel Core i9-11950H vs AMD Ryzen 9 5900HX: comparison
Comparison of Intel Core i9-11950H and AMD Ryzen 9 5900HX: key differences and a full specification table.
Key differences
Intel Core i9-11950H has a higher maximum clock (5 GHz vs 4.6 GHz), a larger L3 cache (24 MB vs 16 MB) and a newer PCIe version (4 vs 3).
At the same time, AMD Ryzen 9 5900HX has a finer process node (7 nm vs 10 nm) and a higher maximum integrated graphics clock (2.1 GHz vs 1.45 GHz).
Both processors match on: core count (8), thread count (16).
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.
