CPU Comparison

Intel Core i7-8560U vs Intel Core i7-8665UE

A side-by-side comparison of specs, performance and value. The Intel Core i7-8560U is a highly efficient mobile processor introduced as part of the Whiskey Lake lineup, specifically engineered for thin-and-light ultrabooks. Featuring four cores and eight threads, it brought mainstream quad-core performance to the ultra-low-power segment. Operating at a base frequency of 1.8 GHz, it can dynamically boost up to 4.6 GHz when thermal headroom permits, delivering snappy burst performance for everyday tasks and moderate workloads. With a 15-watt thermal design power, it balances battery longevity with processing capability. The integrated Intel UHD Graphics 620 handles basic display outputs and light multimedia tasks, though it is not suited for intensive gaming. This CPU marked a significant step in Intel's 8th generation strategy, offering increased core counts over previous ultra-low-voltage dual-core designs, thereby reshaping user expectations for portable computing power. Released in late 2018, it became a staple in premium business and consumer laptops, providing a reliable computing experience for professionals on the go who require multitasking capabilities without sacrificing portability.
