Intel Core 4th Generation · Haswell
A Haswell-generation U-series chip on Intel's 14nm process, the 4200U brought two cores, four threads, and a 15W TDP with a fairly narrow 2.3–2.6GHz clock range.
Haswell's architectural improvements over Ivy Bridge showed up more in battery life and integrated graphics than in raw clock speed at this tier.
Up to 2.6 GHz boost clock.
Supported memory generations. Soldered (LPDDR) or upgradeable depends on the laptop.
