Is Intel adopting a new naming scheme for its Lakefield processor? In the Userbenchmark database, Twitter user TUM_APISAK discovered a Samsung computer with device ID "SAMSUNG_NP_767XCL". This model features the Intel Core i5-L16G7, a chip that identified as a model with five cores, five threads, a 1.4GHz base clock, and 1.75GHz Boost.
Lakefield is a new concept similar to ARM big.LITTLE, you get one high-performance Sunny Cove and four small, Tremont cores. The latter take care of low-intensity tasks with greater energy efficiency, while the Sunny Cove core can deliver a performance boost when it's really needed.
Clock speeds of the processor are listed as "1.40 GHz base, with 1.75 GHz turbo," but it's possible that the two core types have different clock-speed bands, just like the cores on big.LITTLE SoCs. Other key components of "Lakefield" include an iGPU based on the Gen11 graphics architecture, and an LPDDR4X memory controller. "Lakefield" implements Foveros packaging, in which high-density component dies based on newer silicon fabrication nodes are integrated with silicon interposers based on older fabrication processes, which facilitate microscopic high-density wiring between the dies. In case of "Lakefield," the Foveros package features a 10 nm "compute field" die sitting atop a 22 nm "base field" interposer.
It's believed that the first letter in L16G7 represents the product type followed by a model number. The "G" means the part has integrated graphic and the last digit denotes the tier of the integrated graphics.
