Intel Core i5-1240U vs Intel Core i5-1334U: Comparison

Core i5-1240U vs Core i5-1334U p-core boost clock compared

The first real difference is p-core boost clock: Core i5-1240U 4.4 GHz against Core i5-1334U 4.6 GHz. Base power is not the same on both, 9 W on the Core i5-1240U versus 15 W on the Core i5-1334U. There is a split on max turbo power as well, 29 W on the Core i5-1240U versus 55 W on the Core i5-1334U. There is a split on memory type as well, LPDDR5, LPDDR4x on the Core i5-1240U versus DDR5, DDR4, LPDDR5/x, LPDDR4x on the Core i5-1334U.

Which should you buy, Core i5-1240U or Core i5-1334U?

The Core i5-1240U suits ultra-thin laptops and business laptops, though it is not the pick for gaming laptops and heavy sustained workloads. The Core i5-1334U is the one to take for budget and midrange 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. It is the wrong buy for heavy video rendering or code compiling, where H-series chips finish sooner. Our rating of the Core i5-1240U (7.7/10): the Intel Core i5-1240U prioritizes battery life and portability, fitting thin business and everyday laptops. Our rating of the Core i5-1334U (7.7/10): the Intel Core i5-1334U prioritizes battery life and portability, fitting thin business and everyday laptops.

What Core i5-1240U and Core i5-1334U have in common
