— formally, quad-core CPUs are more advanced than dual-core ones. However, there is an important nuance in practice. This design can be used not only in traditional desktop or laptop CPUs but also in mobile energy-saving solutions designed for ultra-compact devices. The latter significantly lag behind the former in computing power — to the point that dual-core desktop processors are often more advanced than quad-core mobile ones. Therefore, when choosing a laptop with a quad-core CPU, you should not rely on the number of cores but rather clarify the overall characteristics and features of the processor (primarily the series).
