Intel Core i5-8300H vs Intel Core i5-8400H: comparison

Comparison of Intel Core i5-8300H and Intel Core i5-8400H: key differences and a full specification table.

Key differences

Intel Core i5-8400H has a higher base clock (2.5 GHz vs 2.3 GHz), a higher maximum clock (4.2 GHz vs 4 GHz) and a higher maximum integrated graphics clock (1.1 GHz vs 1 GHz).

Both processors match on: core count (4), thread count (8), L3 cache (8 MB), TDP (45 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.
