Intel Core i5-8600K vs Intel Core i7-7700K: comparison

Comparison of Intel Core i5-8600K and Intel Core i7-7700K: key differences and a full specification table.

Key differences

Intel Core i5-8600K has more cores (6 vs 4), a larger L3 cache (9 MB vs 8 MB) and a higher maximum memory size (128 GB vs 64 GB).

At the same time, Intel Core i7-7700K has more threads (8 vs 6), a higher base clock (4.2 GHz vs 3.6 GHz), a higher maximum clock (4.5 GHz vs 4.3 GHz) and a lower TDP (91 W vs 95 W).

Both processors match on: process node (14 nm), memory channels (2), PCIe version (3), maximum integrated graphics clock (1.15 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.
