Amd zen 2 has specter v4 hardware mitigation
Table of contents:
The information we are receiving from the new Zen 2 processors are increasingly interesting and promising, as they enhance the expectations we have of AMD . They are not only an improvement in power, but also in safety and here we tell you why.
AMD Zen 2, a secure micro-architecture
AMD is publishing data on its new Zen 2 processors, currently the Ryzen 3000, where they discuss different perspectives of its components. Recently, we have been able to see information about its security systems where the company reaffirms its resistance against different vulnerabilities.

According to the brand itself, the Zen 2 micro-architecture is totally immune to the Specter V4 (Speculative Store Bypass) vulnerability . While Zen and Zen + fixed it using software-made solutions, Zen 2 has a hardware mitigation system.
Commonly, hardware-based solutions affect the overall performance of the component much less, so they are more recommended.
On the other hand, Zen 2 is not only immune to the current Specter V4, but also inherits the resistance of its predecessors to other vulnerabilities such as:
- Meltdown Foreshadow Specter V3a Lazy FPU Spoiler MDS vulnerabilities
If we put it in perspective, the micro-architecture of the blue team "Coffe Lake Refresh" depends entirely on software solutions, which slightly affects its performance. More specifically, Intel is now forced to mitigate the Specter V4 , Specter V3a vulnerabilities and the recent MDS and RIDL vulnerabilities through software .
Actually, the Texan company is doing it, a priori eye, very well with its new processors and graphics cards, but will they finally be as good as everyone expects? We will soon be able to verify it, since the Ryzen 3000 processors are already around the corner.
Do you trust the data and rumors we have about AMD Ryzen 3000 and Zen 2 ? Or do you think the market will change or will Intel and Nvidia keep control? Share your ideas in the comment box.
