Tiger Lake (microarchitecture)

Tiger Lake is an Intel CPU microarchitecture based on the third-generation 10 nm process node (named "10nm++").[1] It will replace Ice Lake,[2] representing the Optimization step in Intel's Process-Architecture-Optimization model.

Tiger Lake is slated to include quad-core 9 W TDP and 25 W TDP models.[3] It will power some 2020 "Project Athena" laptops.[4] The quad-core 96 EU die measures 13.6 by 10.7 mm (146.1 mm2), which is 19.2% wider than the 11.4 by 10.7 mm (122.5 mm2) quad-core 64 EU Ice Lake die.[5]
