Intel announced low power mobile Whiskey Lake CPUs availability on August 28, 2018.[1][2] It has not yet been advertised whether this CPU architecture contains hardware mitigations for Meltdown/Spectre class vulnerabilities—various sources contain conflicting information.[3][4][2][5] Unofficially it was announced that Whiskey Lake has hardware mitigations against Meltdown and L1TF while Spectre V2 requires software mitigations as well as microcode/firmware update.[6][7][8][9] Architecture changes compared to Kaby Lake Refresh
Spectre and Meltdown mitigations in modern Intel CPU architectures{{main|Meltdown (security vulnerability)|Spectre (security vulnerability)|Foreshadow (security vulnerability)}}The 8th generation Coffee Lake architecture in this table also applies to a wide range of previously released Intel CPUs, not limited to the architectures based on Intel Core, Pentium 4 and Intel Atom starting with Silvermont.[10][11]
