Intel’s thirteenth Gen Raptor Lake Desktop CPUs may be a refresh of Alder Lake however they will not be simply a typical clock bump like earlier generations. The Raptor Lake CPU lineup is anticipated to return with a variety of enhancements, one in every of them being DLVR.
Intel Raptor Lake CPUs To Make the most of DLVR ‘Digital Linear Voltage Regulator’ To Preserve Energy & Enhance Efficiency
The data relating to Intel’s Raptor Lake CPUs using the brand new DLVR ‘Digital Linear Voltage Regulator’ know-how comes from Reddit via a patent which was first found by insider, UnderFox. Underfox has been protecting patents of assorted corporations and disclosing helpful information that will get us an perception on upcoming applied sciences. The DLVR was additionally seen talked about inside the leaked slides found by Videocardz some time again. Like Haswell’s FIVR, the DLVR will likely be utilized on Raptor Lake CPUs as an on-chip voltage regulator.

Intel has lately printed extra particulars relating to DLVR in a patent titled ‘Digital Linear Regulator Clamping Technique and Equipment’. The patent explains that DLVR will act as a secondary regulator along with the principle voltage regulator that will likely be featured on the motherboard for the CPU. The aim of the secondary DLVR regulator is to decrease the facility consumption in an economical method and likewise via a course of that requires much less complexity.
Presently, Intel CPUs that depend on motherboards for voltage laws can sip in larger than the standard voltage that leading to larger warmth and energy consumption. The primary suspects on this are the motherboard load-line calibration (LLc) and the CPU’s personal present requirement together with the motherboard voltage regulator generally inflicting inaccuracies in voltage administration. The DLVR will act as a safeguard in opposition to these and can assist hold the voltage numbers in verify for the CPU & end in decrease energy consumption and warmth technology.
The patent additionally reveals that Intel Raptor Lake CPUs with DLVR can scale back voltage by 160mV, a 20-25% drop in comparison with conventional designs. A drop of 21% in voltage additionally implies that the CPU positive factors roughly 7% larger efficiency. Along with this, the Raptor Lake CPUs with DLVR may also sip in decrease voltage to succeed in the present (Ampere) targets with a extra environment friendly V-I Curve.
Plot 500 reveals that’s doable to get rid of as a lot as 160 mV of the CPU voltage Vin, which interprets to about 25% to 25% lower of the CPU energy as proven in plot 520. Right here, the portion exhibiting the facility saving past 40A doesn’t take note of the D-LVR losses. On this instance, a 21% drop within the CPU is translated to roughly 7% efficiency achieve.”
Intel’s Raptor Lake lineup, extra particularly the laptop computer variants, is anticipated to make the most of the DLVR tech. Together with DLVR, the CPU lineup can also be anticipated to supply elevated core/thread counts, a refined structure design within the type of Raptor Cove, larger clocks, extra cache, and assist for sooner DDR5/LPDDR5X reminiscence. The household is meant to launch by the tip of 2023.
