Intel Arrow Lake processors should be more power efficient than Raptor Lake processors

Intel’s soon-to-be-introduced Meteor Lake processors will overtake the LGA 1851 desktop platform. The new socket will be introduced next year, along with Arrow Lake-S processors. The next generation of Core Ultra systems will introduce not only the new x86 architecture for performance (Lion Cove) and efficient (Skymont) cores, but also the new Intel 20A technology process. If the information presented is confirmed, new lithography will significantly impact the energy consumption of systems.

According to unofficial information, Intel Arrow Lake-S processors will feature much lower PL2 and PL4 coefficients compared to current Raptor Lake-S systems.

Intel Arrow Lake, Lunar Lake, and Panther Lake – New information about Intel Core Ultra PC processors

Information about next year’s Intel Arrow Lake-S processors for the desktop platform has appeared on the Internet. They showed that systems based on the Lion Cove and Skymont architectures would feature much lower power consumption in scenarios when, for example, the cores run at clock speeds higher than the base speed (Turbo). In the case of the base PL1 factor, which sets the power limits for the core clocks, Arrow Lake-S processors (systems with an unlocked multiplier) will deliver the same 125 watts as current Raptor Lake-S units.

It becomes more interesting when we look at the coefficients of PL2 and PL4. The first one in the Arrow Lake-S is said to be 177 watts. For comparison, the Raptor Lake-S has that factor of 253 watts. This represents a 43% lower power consumption value compared to PL2 (76 W difference). In the case of PL4, Arrow Lake-S processors are expected to have a power consumption of 333W, while, for comparison, Raptor Lake-S processors are rated at 420W. This represents a 26% reduction in energy consumption between both generations. . These parameters are influenced by both the more energy efficient architecture and the new technological process. This is not currently confirmed information (there is a lot of time left until the premiere and there is still a lot of change), but if these values ​​​​are offered by ready processors, it will be very good news.
