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] Laptops based on Tiger Lake started to sell in October 2020.[8]

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.[9] Intel also announced that the Tiger Lake-H processors with 45 W TDP and up to eight cores will become available in Q1 2021.[10]

AVX/AVX2 instructions support for Pentium Gold and Celeron processors has been unlocked

GPU

Intel Xe-LP ("Gen12") GPU with up to 96 execution units[19] (50% uplift compared to Ice Lake) with some yet to be announced processors using Intel's discrete GPU, DG1[20][21]
Fixed-function hardware decoding for HEVC 12-bit, 4:2:2/4:4:4; VP9 12-bit 4:4:4 and AV1 8K 10-bit 4:2:0[22][23][24]
Support for a single 8K 12-bit HDR display or two 4K 10-bit HDR displays
Hardware accelerated Dolby Vision
Sampler Feedback[25][26][27] support

I/O

PCI Express 4.0[28] (Pentium and Celeron CPUs are limited to PCI Express 3.0)
Thunderbolt 4 (includes USB4)
LPDDR4X-4267 memory support
LPDDR5-5400 "architecture capability" (Intel expects Tiger Lake products with LPDDR5 to be available around Q1 2021)[29][30][31] Consumer parts and SO-DIMM DDR5 memory modules are yet to be announced.
Miniaturization of CPU and motherboard into an M.2 SSD-sized small circuit board[20]
