Not too long ago, Intel had released its Kaby Lake Refresh (henceforth Kaby Lake R), or 8th-generation processors for laptops and tablets. At the time, they were billed as an evolution of the previous, 7th-generation chips, bringing quad-core designs to the i5 line and therefore more power.

However, these chips have also been said to boost efficiency when it comes to power consumption.
