Benchmarks & Specs

Last updated:
The Intel Core i5-1240U is a processor from the Alder Lake U generation. It was specifically designed for use in slim notebooks. Its remarkable energy efficiency is particularly noteworthy. This contributes significantly to longer battery life. Such aspects are crucial for mobile devices. It still delivers very usable overall performance for most everyday applications.

Whether it's browsing, office work, or streaming content, this chip handles it well. Another plus is the integrated Intel Iris Xe Graphics 80 (Alder Lake). This graphics unit enables clear image reproduction. It is also suitable for the smooth display of videos and occasional, less demanding games. We were surprised at the time by how versatile this integrated solution is.

The processor also benefits from its generous cache memories. With 7 MB L2 cache and 12 MB L3 cache, data is processed quickly. The result is a noticeably smoother user experience. The memory bandwidth of 83 GB/s also ensures a good system response. The Intel Core i5-1240U thus offers a well-thought-out balance.

It combines solid performance with low power consumption. This makes it a reliable choice for many laptop models.
