AMD Zen 2 has Hardware Mitigation for Spectre V4

AMD in its technical brief revealed that its Zen 2 microarchitecture has hardware mitigation against the Spectre V4 speculative store bypass vulnerability. The current generation "Zen" and "Zen+" microarchitectures have OS-level mitigation. 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. In comparison, the 9th generation Core "Coffee Lake Refresh" processors still rely on software or microcode-level mitigation for Spectre V4, Spectre V3a, MDS, and RIDL.

PaddieMayneBeing a native speaker of 47 years, living in the country where the language originated and having been taught the Queens English as it should be taught, i can quite categorically tell you that the abbreviation in the Queens English language stands for Not Applicable. But i of course understand that my rebellious tax fearing cousins from across the pond have taken the beautiful language that is English and bastardized it for their own use, which i blame mainly on American Media and Commercial Enterprises. :)

But I digress ;)
Praise be Elizabeth!
