Intel Core i3-8100 vs Intel Core i5-7400: comparison
Comparison of Intel Core i3-8100 and Intel Core i5-7400: key differences and a full specification table.
Key differences
Intel Core i3-8100 has a higher base clock (3.6 GHz vs 3 GHz) and a higher maximum integrated graphics clock (1.1 GHz vs 1 GHz).
Both processors match on: core count (4), thread count (4), L3 cache (6 MB), TDP (65 W), process node (14 nm), maximum memory size (64 GB), memory channels (2), PCIe version (3).
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.
