Intel Core i5-6350HQ vs Intel Core i5-6440HQ: comparison
Comparison of Intel Core i5-6350HQ and Intel Core i5-6440HQ: key differences and a full specification table.
Key differences
Intel Core i5-6440HQ has a higher base clock (2.6 GHz vs 2.3 GHz), a higher maximum clock (3.5 GHz vs 3.2 GHz) and a higher maximum integrated graphics clock (950 MHz vs 900 MHz).
Both processors match on: core count (4), thread count (4), L3 cache (6 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.
