CPU Comparison
Core i5-1230U vs Core i5-1235U (IPU)
A side-by-side comparison of specs, performance and value. The Intel Core i5-1230U is an ultra-low power mobile processor crafted for the thinnest and lightest laptops, as well as fanless designs. Released in February 2022 as part of the Alder Lake-U family, it features a 9W base TDP, significantly lower than the standard 15W U-series chips. Despite its power-efficient design, it retains the 10-core, 12-thread hybrid architecture, combining 2 Performance-cores and 8 Efficient-cores. This allows it to deliver surprising burst performance for everyday tasks while sipping power during idle or light usage. The P-cores start at a modest 1.0 GHz base clock but can boost up to 4.4 GHz when needed. With Intel Iris Xe 80EU graphics, it handles 4K media playback and casual gaming competently. The i5-1230U is the perfect candidate for users who prioritize extreme battery life and portability above all else.
