Intel's Lakefield processor architecture arrives Wednesday in new Core i5-L16G7 and i3-L13G4 chips that look to challenge Qualcomm's processor platform in the pursuit of full-day battery life for Windows laptops. The new Cores come at a time when Apple is reportedly breaking away from Intel to produce computer CPUs based around its own ARM-hybrid architecture, kin of the A13 and family used in its iPhones and iPads.
Like phone processors, these chips mix high- and low-power cores, routing tasks as necessary to provide more efficient use of the battery. Intel's hyped them for novel dual-screen and folding devices such as the Lenovo ThinkPad X1 Fold and Samsung Galaxy Book S -- the latter uses a Qualcomm chip but will have a model built on Intel -- predominantly because of their dual graphics pipelines, designed to drive multiple displays.
Intel's Lakefield processor uses a more powerful processor core for performance-intensive tasks -- shown here in purple as a web page loads -- then shuffles the work to lower-power cores, shown here in yellow and orange. Once the work is done, the processor activity tapers down, with just little spurts of background activities using the low-power cores. (Slide from August 2019.)
