Tiger Lake is the code-name for Intel's 11th generation mobile processors based on Intels "Willow Cove Core" architecture. The processors are manufactured on Intel's 10nm "SuperFin" production node. Tiger Lake processors will feature "Intel Xe" integrated graphics which Intel in their marketing claims is more powerful than the integrated graphics in comparable mobile processors from competitor AMD.
i5 and i7 Tiger Lake "UP3" laptop models have four cores and eight threads at TDPs ranging from 12 to 28W. The i3 models are limited to two cores. The i5 and i7 "UP4" ultrabook models are also four core/eight thread parts with TDP ratings from 7 to 15W.

Linux Support[edit]
Linux 5.8+ supports all the Tiger Lake processor specific features. Hardware video decoding is supported through VAAPI. HEVC and VP9 support has been present in VAAPI for a very long time, AV1 hardware decoding support was merged to VAAPI in August 2020.
