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]

  • Miniaturization of CPU and motherboard into an M.2 SSD-sized small circuit board[9]
  • Indirect branch tracking and shadow stack[16]
gollark: Now, that is *not* fully working: its WiFi chip appears to have abandoned this mortal plane in some way.
gollark: In terms of bizarre accursed devices, I *do* have an old Kindle from circa 2015.
gollark: I mean, I think it's still fully working.
gollark: I don't *think* so.
gollark: It has four unbroken ARMv8 ones.
