Tiger Lake is Intel's codename for the 11th generation Intel Core mobile processors based on the new Willow Cove Core microarchitecture, manufactured using Intel's third-generation 10 nm process node known as 10SF ("10 nm SuperFin"). Tiger Lake replaces the Ice Lake family of mobile processors,[2] representing an Optimization step in Intel's process–architecture–optimization model.
Tiger Lake processors launched on September 2, 2020 are part of the Tiger Lake U family and include dual-core and quad-core 9 W (7-15 W) TDP and 15 W (12-28 W) TDP models.[3] They power 2020 "Project Athena" laptops.[4][5][6] 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. According to Yehuda Nissan and his team, the architecture is named after a lake across Puget Sound, Washington.[7] Tiger Lake H family of processors is expected to launch in Q1 2021 with an expected TDP of 45 W.
Laptops based on Tiger Lake started to sell in October 2020.[8]
Intel announced it would release eight-core Tiger Lake H CPUs at "a later date".[9]
