The -7xxx processor is Kaby Lake, not Ice Lake.
The -8xxx processor is not Tiger Lake, the Refreshed KabyLake
If I may caution, please be very careful not to confuse the ASIC technology with the CPU designator.
-6xxx = Sky Lake
-7xxx = Kaby Lake
-8xxx = Coffee Lake
-9xxx = Cannon Lake
-10xxx = Ice Lake
Tiger Lake will be 11th Gen.
