. Tiger Lake processors launched on September 2, 2020. They are part of the Tiger Lake-U family (however, they end with the suffixes -G4 and -G7 instead of -U) and include dual-core and quad-core 9 W (7–15 W) TDP and 15 W (12–28 W) TDP models. They power 2020 Intel Evo 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. 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 officially launched the 11th generation Intel Core-H series and Xeon W-11000M series on May 11, 2021 and announced the 11th generation Intel Core Tiger Lake Refresh series (1195G7 and 1155G7) on May 30, 2021.
