Intel Raptor Lake CPUs To Feature Digital Linear Voltage Regulator 'DLVR' - Could Help Reduce Power Consumption By 25%
Intel's 13th Gen Raptor Lake Desktop CPUs might be a refresh of Alder Lake merely they won't be only a standard clock bump like previous generations. The Raptor Lake CPU lineup is expected to come with a range of improvements, i of them beingness DLVR.
Intel Raptor Lake CPUs To Utilize DLVR 'Digital Linear Voltage Regulator' To Conserve Ability & Improve Performance
The information regarding Intel's Raptor Lake CPUs utilizing the new DLVR 'Digital Linear Voltage Regulator' applied science comes from Reddit through a patent which was first discovered by insider, UnderFox. Underfox has been covering patents of diverse companies and disclosing useful data that gets us an insight on upcoming technologies. The DLVR was also seen mentioned within the leaked slides discovered past Videocardz a while back. Like Haswell'south FIVR, the DLVR will be utilized on Raptor Lake CPUs as an on-chip voltage regulator.
The basic idea backside Raptor Lake'south new power delivery compages proposal is to include a digital linear voltage regulator (DLVR) as a voltage clench placing in parallel to the primary VR, reducing CPU VID and thereby too reducing processor core power consumption. movie.twitter.com/n7kwjwTY9C

Intel has recently published more details regarding DLVR in a patent titled 'Digital Linear Regulator Clamping Method and Apparatus'. The patent explains that DLVR volition act equally a secondary regulator in addition to the main voltage regulator that will be featured on the motherboard for the CPU. The purpose of the secondary DLVR regulator is to lower the ability consumption in a price-effective manner and also through a process that requires less complexity.
Currently, Intel CPUs that rely on motherboards for voltage regulations can sip in higher than the usual voltage that resulting in higher heat and ability consumption. The main suspects in this are the motherboard load-line scale (LLc) and the CPU's ain current requirement along with the motherboard voltage regulator sometimes causing inaccuracies in voltage management. The DLVR will act as a safeguard confronting these and will help continue the voltage numbers in bank check for the CPU & result in lower power consumption and heat generation.
The patent also shows that Intel Raptor Lake CPUs with DLVR can reduce voltage past 160mV, a xx-25% drop compared to traditional designs. A drop of 21% in voltage also means that the CPU gains roughly 7% higher functioning. In improver to this, the Raptor Lake CPUs with DLVR will also sip in lower voltage to reach the current (Ampere) targets with a more than efficient 5-I Curve.
Plot 500 shows that is possible to eliminate as much equally 160 mV of the CPU voltage Vin, which translates to about 25% to 25% decrease of the CPU power as shown in plot 520. Here, the portion showing the power saving beyond 40A does non accept into account the D-LVR losses. In this example, a 21% drop in the CPU is translated to approximately 7% functioning gain."

Intel's Raptor Lake lineup, more specifically the laptop variants, is expected to utilize the DLVR tech. Along with DLVR, the CPU lineup is likewise expected to offer increased core/thread counts, a refined compages design in the class of Raptor Cove, higher clocks, more enshroud, and support for faster DDR5/LPDDR5X memory. The family is supposed to launch past the terminate of 2022.
