Intel has come clean to Anandtech regarding the level of Spectre and Meltdown protection within its new 8th-generation Whiskey Lake U series Core processors and 8th-gen Amber Lake Y series processors, concluding that its hardware-based defenses against the security flaws aren’t as extensive as we might have expected when Intel promised these fixes earlier this year.

Anandtech created a helpful visual guide for exactly which Spectre and Meltdown defenses have been baked into the Whiskey Lake and Amber Lake hardware. Intel tells Anandtech that there are almost as many hardware fixes for the Whiskey Lake chips as there are in the upcoming Cascade Lake processors for servers.
