Intel Core i5 10210U

A Comet Lake i5 with four cores and eight threads at 15W, the 10210U reaches a 4.2GHz boost clock despite a modest 1.6GHz base — typical of how Intel's U-series chips leaned hard on turbo behavior to feel responsive under light loads.

Built on the well-worn 14nm process, it was a common mainstream choice for thin laptops in its generation, offering real quad-core multitasking without the power draw of an H-series chip.
