AMD Immune to MDS Vulnerabilities

Meanwhile, AMD maintains that Zombieload, just like Meltdown, Foreshadow, and Spoiler before, only affects Intel processors and not any produced by AMD. Operating system- and software-level solutions to Intel’s many vulnerabilities (which even include disabling Hyper-Threading, something Intel charges extra for) reduce the performance of its processors. Consumers with Intel processors may accept these vulnerabilities so as to avoid performance penalties, but those who opted for Ryzen, Threadripper, and Epyc, are surely relieved that they can escape with their performance intact and security unaffected.
