Tiger Lake (microprocessor)

Tiger Lake is Intel's codename for the 11th generation Intel Core mobile processors based on the new Willow Cove Core microarchitecture, to be manufactured using Intel's third-generation 10 nm process node (named "10nm SuperFin"). Intel announced on August 5, 2020 that it would launch Tiger Lake on September 2, 2020 via webcast.[1] It is expected that Tiger Lake will replace the Ice Lake family of mobile processors,[2] representing an Optimization step in Intel's Process-Architecture-Optimization model.

Tiger Lake will include quad-core 9 W TDP and 28 W TDP models.[3] It will power some 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.[7]

Features
  • Intel Willow Cove CPU cores
  • Intel Xe ("Gen12") GPU with up to 96 execution units[8] with some processors using Intel's discrete GPU, DG1[9]
  • HEVC 12-bit, 4:2:2 & 4:4:4 fixed-function hardware decoding & VP9 12-bit 4:4:4 fixed-function hardware decoding & AV1 10-bit 4:2:0 fixed-function hardware decoding[10][11]
  • PCI Express 4.0[12]
  • Thunderbolt 4
  • USB4
  • LPDDR5 memory [13]
  • New Deep Learning Boost (DL Boost) extensions for built-in AI training acceleration in Xeon processors[14]
  • A new AVX-512 instruction: Vector Pair Intersection to a Pair of Mask Registers (VP2INTERSECT).[15]
  • Miniaturization of CPU and motherboard into an M.2 SSD-sized small circuit board[9]
  • Indirect branch tracking and shadow stack[16]
gollark: Chromatic aberration induced by the gay field is well-documented and is in fact the operating principle of gaydar.
gollark: ↑
gollark: As I've said before, I don't think it was ever that.
gollark: We can only measure it from consumer preferences, and (since people would lie if you directly *asked* about their willingness to pay for various things for various reasons), short of orbital mind-reading lasers, the only useful way to do this is observing markets.
gollark: Value isn't an objective thing like mass or charge or whatever, however.
