Our Verdict on Each
A solid 15W CPU that balances 10-core multitasking with excellent battery life, ideal for standard productivity and portability.
Best for: Ultraportable laptops for students and office workers.
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.
