We can define Intel’s 13th Generation Raptor Lake-S desktop processors as a kind of refreshed version of Alder Lake. We don’t know exactly what improvements will be made in the next generation, but it looks like different clock multipliers will be used from previous generations.

The Raptor Lake CPU series is expected to come with DLVR (Digital Linear Voltage Regulator) technology. According to the newly discovered patent, DLVR will be used as an on-chip voltage regulator in Raptor Lake CPUs, like Haswell’s FIVR technology.

Intel recently published more details regarding the DLVR in a patent entitled ‘Digital Linear Regulator Compression Method and Apparatus’. The patent explains that the DLVR will act as a secondary regulator for the CPU in addition to the main voltage regulator that will be located on the motherboard. The purpose of the secondary DLVR regulator is to reduce the power consumption in a low cost way and also with a less complex process.

Intel CPUs that currently rely on motherboards for voltage regulation can be subjected to higher voltages resulting in higher heat and power consumption. The DLVR will act as a protection against these, helping to control voltage counts for the CPU, and provide lower power consumption/heat generation.

The patent also shows that Intel Raptor Lake chips with DLVR can reduce voltage by 160mV, a 20-25% reduction compared to traditional designs. A voltage drop of 21% means the CPU gains roughly 7% higher performance. In addition, Raptor Lake CPUs with DLVR will also draw lower voltage to meet current (Amperes) targets with a more efficient V-I Curve.

However, Raptor Lake mobile processors are also expected to use DLVR technology. In addition to this feature, we expect an increase in core/thread counts, a refined architectural design, higher frequencies and a greater amount of cache.
