Intel Core i7-8565U vs Intel Core i7-8559U: comparison
Comparison of Intel Core i7-8565U and Intel Core i7-8559U: key differences and a full specification table.
Key differences
Intel Core i7-8565U has a higher maximum clock (4.6 GHz vs 4.5 GHz), a lower TDP (15 W vs 28 W) and a higher maximum memory size (64 GB vs 32 GB).
At the same time, Intel Core i7-8559U has a higher base clock (2.7 GHz vs 1.8 GHz) and a higher maximum integrated graphics clock (1.2 GHz vs 1.15 GHz).
Both processors match on: core count (4), thread count (8), L3 cache (8 MB), process node (14 nm), 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.
