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 (named "10nm 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 (7-15W) TDP and 15 W (12-28W) 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 45W.
Laptops based on Tiger Lake are expected to become available for purchase in November, 2020.[8]
Intel announced it would release eight-core Tiger Lake H CPUs at "a later date".[9]
Architecture changes

- A new AVX-512 instruction: Vector Pair Intersection to a Pair of Mask Registers (VP2INTERSECT).[12]
- Control Flow Enforcement Technology to prevent Return Oriented Programming and Jump Oriented Programming hacking techniques[13]
- Full memory (RAM) encryption[14]
- Indirect branch tracking and shadow stack[15]
- GPU features
- Intel Xe-LP ("Gen12") GPU with up to 96 execution units[16] (50% uplift compared to Ice Lake) with some yet to be announced processors using Intel's discrete GPU, DG1[17][18]
- Fixed-function hardware decoding for HEVC 12-bit, 4:2:2/4:4:0; VP9 12-bit 4:4:4 and AV1 10-bit 4:2:0[19][20]
- Support for a single 8K 12-bit HDR display or two 4K 10-bit HDR displays
- Hardware accelerated Dolby Vision
- I/O:
- Miniaturization of CPU and motherboard into an M.2 SSD-sized small circuit board[17]
