AMD Zen 2 design has hardware protection for Spectre v4

Posted on Wednesday, June 12 2019 @ 09:35:39 CEST by

In a technical briefing, AMD confirmed that its Zen 2 architecture offers hardware-level protection against the Spectre and Spectre v4 vulnerability. This should result in a lower performance impact than the current, software-based protections.
A hardware mitigation typically has less of a performance overhead than a software mitigation deployed at the OS or firmware level. In addition, just like older generations of "Zen," the new "Zen 2" microarchitecture is inherently immune to Meltdown, Foreshadow, Spectre V3a, Lazy FPU, Spoiler, and the recently discovered MDS vulnerability.
