Intel Core i5-8400H vs Intel Core i5-8500B: comparison
Comparison of Intel Core i5-8400H and Intel Core i5-8500B: key differences and a full specification table.
Key differences
Intel Core i5-8400H has more threads (8 vs 6), a higher maximum clock (4.2 GHz vs 4.1 GHz) and a lower TDP (45 W vs 65 W).
At the same time, Intel Core i5-8500B has more cores (6 vs 4), a higher base clock (3 GHz vs 2.5 GHz) and a larger L3 cache (9 MB vs 8 MB).
Both processors match on: process node (14 nm), maximum memory size (64 GB), memory channels (2), PCIe version (3), maximum integrated graphics clock (1.1 GHz).
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.
