Energy-efficient laptops and processors, in depth

In the previous article, we discovered the value offered by SSD units in laptop computers. This essential component allows the creation of lighter and more efficient, reliable and silent devices without sacrificing superior performance.

Today we are going to focus on another component that is fundamental to both desktop computers and laptops, the processor or CPU.


This component is considered the brain of any system, which is appropriate given it carries out all those tasks necessary to a device’s correct functioning.

The CPU’s multipurpose capacity makes it one of the key parts of any computer, and the performance of other components – such as the graphics card, RAM or even storage units – directly depends on it.

It is clear that processing power matters, but when speaking of laptop computers, we must also consider energy efficiency, operating temperatures and above all battery life.

This means that a good processor for laptop computers is not the one that offers the best brute performance, but rather that which achieves greatest equilibrium between the three criteria identified in the previous paragraph.

Intel® Core™ U-series, the perfect balance

With its Intel® Core™ U-series processors, the chip-making giant has shown that it is possible to achieve perfect equilibrium between performance, operating temperatures and energy efficiency.

Thanks to its innovative 14-nanometer manufacturing process, the Santa Clara giant’s new Intel® Core™ U-series processors offer top-shelf performance that allows us to work with demanding applications without problems, while minimizing energy use.

Regardless of whether we are working in single- or multi-core environments, the low CPI (cycles per instruction) of Intel® Core™ U-series processors, based on Kaby Lake architecture and hyper-threading technology, allows us to enjoy all the power we need without compromising battery life.

Models like the Intel® Core™ i7 7600U have two high-performance cores and four threads working at a dynamic frequency of 2.7 GHz to 3.5 GHz, allowing the processor to intelligently adapt itself to different workloads and offer excellent performance with the lowest possible energy use.

Its TDP is configurable from 7.5 watts to 25 watts, very low figures that translate to high energy efficiency and very low temperatures.

This not only allows for good battery life on each charge while maintaining great performance, but also helps laptop manufacturers create lighter and slimmer designs, as they can mount simpler and quieter cooling systems.

The value of balance is clear, and HP has been able to perfectly transfer it to devices as attractive as the popular Spectre x360.
