With a new technical approach to voltage regulation, Intel plans to vastly improve the power consumption and energy efficiency of its upcoming Raptor Lake CPUs, which could be particularly advantageous for its mobile chipsets.

Intel's brand-new Alder Lake CPUs like the Intel Core i7-12700K (from US$459 on Amazon) are barely on the market, and we already witness the emergence of new rumors and speculations regarding Intel's next processor generation known under the codename "Raptor Lake", which could be released in 2022. According to a report by Tom's Hardware, Raptor Lake could see the introduction of a new type of voltage regulation and therefore offer significant improvements in terms of energy efficiency.

Intel's patented technology is called "digital linear voltage regulator", or D-LVR in short. This component is intended to notably reduce the power consumption of Raptor Lake CPUs. Simply said, Intel adds another voltage clamp in addition to the regular voltage regulator. According to Intel's example, this clamp is active when a CPU requires a current of less than 40A, which should be the case in most mobile use cases. This consequently reduces the power drawn by the CPU. The exact technical details of this D-LVR implementation are laid out in Intel's according patent publiation.

Intel expects that this approach reduces the power consumption of Raptor Lake CPUs by 20 to 25%, which would also result in better performance which could see improvements of around 7%. In the end, Intel appears to be focused on finally catching up to AMD's Ryzen Zen 3 processors, which are currently superior in terms of energy efficiency. Mobile Raptor Lake chipsets will also introduce support for LPDDR5X RAM.

My fascination for technology goes back a long way to the Pentium II era. Modding, overclocking and treasuring computer hardware has since become an integral part of my life. As a student, I further developed a keen interest in mobile technologies that can make the stressful college life so much easier. After I fell in love with the creation of digital content while working in a marketing position, I now scour the web to bring you the most exciting topics in the world of tech. Outside the office, I’m particularly passionate about motorsports and mountain biking.
