Intel Core i3-7100U vs Intel Core i7-6660U: comparison
Comparison of Intel Core i3-7100U and Intel Core i7-6660U: key differences and a full specification table.
Key differences
Intel Core i7-6660U has a larger L3 cache (4 MB vs 3 MB) and a higher maximum integrated graphics clock (1.05 GHz vs 1 GHz).
Both processors match on: core count (2), thread count (4), base clock (2.4 GHz), TDP (15 W), process node (14 nm), maximum memory size (32 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.
