Core i5-1230U vs Intel Core Ultra 5 115U
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.

Our Verdict on Each
An incredibly efficient 10-core processor that brings real multitasking capabilities to 9W fanless designs.
Best for: Ultra-portable, fanless laptops
Read the full reviewA solid entry-level Meteor Lake chip that delivers great battery life and AI features for basic daily tasks.
Best for: The Core Ultra 5 115U is the ideal processor for students, office workers, and casual users who prioritize battery life and affordability. If your daily routine involves document editing, web conferencing, and streaming video, this CPU will handle these tasks effortlessly while providing excellent battery longevity. The integrated NPU adds value by preparing your device for future Windows AI features. However, this is not the processor for video editing, 3D rendering, or gaming; its reduced core count and 48EU graphics are not designed for heavy workloads. If you occasionally dabble in photo editing or light gaming, consider stepping up to the 135U. For purely administrative and educational tasks, the 115U offers outstanding value and efficiency.
