Core 5 120U vs Core i5-1235U: the p-core boost clock difference
They are built to different briefs, and p-core boost clock shows it, Core 5 120U 4.7 GHz against Core i5-1235U 4.4 GHz.
Core 5 120U vs Core i5-1235U: which one fits your build
The Core 5 120U is the one to take for affordable everyday and business thin-and-light laptops and office work, browsing, video calls and streaming, though it is the wrong buy for gaming beyond older or light titles at low settings and AI features that need an NPU, since it has none. It is equally the pick for buyers who want a quick, simple laptop without paying for AI features. It is the wrong buy for heavy video rendering or code compiling, where H-series chips finish sooner. The Core i5-1235U suits budget, business and refurbished thin-and-light laptops and office work, browsing, video calls and streaming, though it is not built for gaming beyond older or light titles at low settings. Avoid it for heavy video rendering or code compiling, where H-series chips finish sooner.
