Tiger Lake
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, 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. They power 2020 "Project Athena" laptops. The quad-core 96 EU die measures 13.6 × 10.7 mm (146.1 mm2), which is 19.2% wider than the 11.4 × 10.7 mm (122.5 mm2) quad-core 64 EU Ice Lake die. The 8-core 32 EU die used in Tiger Lake-H is around 190 mm2. According to Yehuda Nissan and his team, the architecture is named after a lake across Puget Sound, Washington. Laptops based on Tiger Lake started to sell in October 2020.

The Tiger Lake-H35 processors were launched on January 11, 2021. These quad-core processors are designed for "ultraportable gaming" laptops with 28-35 W TDP. Intel also announced that the Tiger Lake-H processors with 45 W TDP and up to eight cores will become available in Q1 2021. Intel officially launched 11th Gen Intel Core-H series on May 11, 2021  and announced 11th Gen Intel Core Tiger Lake Refresh series on May 30, 2021.
