Intel Core i5-1155G7 vs AMD Ryzen 5 3450U: comparison
Comparison of Intel Core i5-1155G7 and AMD Ryzen 5 3450U: key differences and a full specification table.
Key differences
Intel Core i5-1155G7 has a higher maximum clock (4.5 GHz vs 3.5 GHz), a larger L3 cache (8 MB vs 4 MB), a finer process node (10 nm vs 12 nm) and a newer PCIe version (4 vs 3).
Both processors match on: core count (4), thread count (8), 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.
