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(slated to ship in the second half of 2020) and -- the latter uses a Qualcomm chip but an Intel model will be available this month -- predominantly because of their dual graphics pipelines, designed to drive multiple displays.
The Lakefield platform also has a tiny package size, thanks to Intel'sand new package-on-package memory.
But the 10nm L series seems like the spiritual successor to the 14nm Y chips, the current Intel choice for current small and light laptops such as theand . The new i5 and i3 have five cores, with no logical processor support (so also five threads) and a power envelope of 7 watts. They differ by clock speed -- 1.4GHz base/3.0GHz single core turbo for the i5 and 800MHz base/2.8 single core turbo for the i3 -- and number of execution units in the graphics core (64 vs. 48). The Y series also has a 7-watt configuration, but the L processors have a much lower standby power draw, as little as 2.5mW. They're updated to the as well, so expect to see improvement there.
We have no reason to believe at the moment that Lenovo or Samsung has put its dual-screen dreams on hold for 2020 like . But it will be far more useful if the new Intel chips make their way into more meat-and-potatoes laptops and Chromebooks.
Previous efforts using Qualcomm's platform, including newsworthy models such as the, don't seem to have much traction because the haven't been worth it. And while Intel continues to tout single-core performance, it remains to be seen how the L series stacks up for mundane multicore-intensive work such as loading applications.
