Intel Core i5-1235U vs Intel Core i5-1335U: Comparison
What is the difference between Core i5-1235U and Core i5-1335U?
P-core boost clock is the dividing line, Core i5-1235U 4.4 GHz against Core i5-1335U 4.6 GHz. Cinebench R23 (Multi-Core) backs the spec sheet up. Core i5-1335U scores 8,970 to 7,884, 12% clear. They differ on release year too, 2022 on the Core i5-1235U versus 2023 on the Core i5-1335U. There is a split on microarchitecture as well, Alder Lake on the Core i5-1235U versus Raptor Lake on the Core i5-1335U. Memory type is not the same on both, DDR5, DDR4, LPDDR5, LPDDR4x on the Core i5-1235U versus DDR5, DDR4, LPDDR5/x, LPDDR4x on the Core i5-1335U.
Core i5-1235U vs Core i5-1335U: which one fits your build
The Core i5-1235U is the one to take for budget, business and refurbished thin-and-light laptops and office work, browsing, video calls and streaming, though it is not the pick 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. The Core i5-1335U suits ultra-thin laptops and business laptops, though it is the wrong buy for gaming laptops and heavy sustained workloads. Our rating of the Core i5-1235U (7.7/10): the Intel Core i5-1235U prioritizes battery life and portability, fitting thin business and everyday laptops. Our rating of the Core i5-1335U (7.7/10): the Intel Core i5-1335U prioritizes battery life and portability, fitting thin business and everyday laptops.
Where the two are identical
The common ground is wider than the gap: total cores, performance cores, efficiency cores, total threads and p-core base clock are identical here. They match on 10 further specifications as well.
Frequently asked questions
Is the TDP the same on the Core i5-1235U and Core i5-1335U?
It is. Both are listed at 15 W, so it is not a reason to pick one over the other.
