Intel Core 3 100U vs Intel Core i3-1315U: Comparison
What is the difference between Core 3 100U and Core i3-1315U?
The first real difference is p-core boost clock: Core 3 100U 4.4 GHz against Core i3-1315U 4.5 GHz. Release year is not the same on both, 2024 on the Core 3 100U versus 2023 on the Core i3-1315U. Igpu is not the same on both, Intel Iris Xe Graphics on the Core 3 100U versus Intel UHD Graphics on the Core i3-1315U. There is a split on memory type as well, DDR5, DDR4, LPDDR5, LPDDR5x, LPDDR4x on the Core 3 100U versus DDR5, DDR4, LPDDR5/x, LPDDR4x on the Core i3-1315U.
Which should you buy, Core 3 100U or Core i3-1315U?
Buy the Core 3 100U for ultra-thin laptops and business laptops, though it is not the pick for gaming laptops and heavy sustained workloads. The Core i3-1315U suits entry-level and student thin-and-light laptops and browsing, documents, email and video calls, though it is not built for gaming beyond very light or older titles. The same goes for buyers on a tight budget who want a modern Intel laptop. It is the wrong buy for heavy multitasking or long multi-core jobs, where Core i5 chips with more cores do better. Our rating of the Core 3 100U (7.7/10): the Intel Core 3 100U prioritizes battery life and portability, fitting thin business and everyday laptops. Our rating of the Core i3-1315U (7.7/10): the Intel Core i3-1315U prioritizes battery life and portability, fitting thin business and everyday laptops rather than performance-first designs.
What Core 3 100U and Core i3-1315U have in common
Everything else lines up. Total cores, performance cores, efficiency cores, total threads and p-core base clock read the same on both, so those are not worth weighing. They match on 8 further specifications as well.
Frequently asked questions
Is the TDP the same on the Core 3 100U and Core i3-1315U?
It is. Both are listed at 15 W, so it is not a reason to pick one over the other.
