Is your computer pre-2016? You can not count much.
We are grateful to note that the case may even come to Microsoft for the "fight against Windows 7".
Microsoft is getting more and more feedback from the Internet about the security incident that has been fired for days, of course we know much more about it than the first few days. Redmond giant specialists have found that the first variant of Meltdown and Specter (CVE 2017-5753 and CVE 2017-5754) is more modest, and the second version of this latter slot (CVE 2017-5715) may have a much more decelerating effect on users' computers. Intel is involved in all three of these, AMD, according to our knowledge, is only the first Specter haunted. In addition to the above, Microsoft summarized what can be expected from patches:
- Windows 10 with a newer central unit (Skylake, Kaby Lake or later) usually produces a one-digit deceleration, most users may not see the difference because they can be measured in milliseconds.
- The same operating system with a previous year's CPU (Hasnam 2015 or older) produces a higher speed reduction at some points, and more people will notice that the computer is running at a much better pace.
- Even worse is the situation with Windows 8 and the popular Windows 7 (!). Here, for most 2016 processors, most users will experience noticeable power losses that are likely to be measurable in milliseconds.
- Windows Server, especially in IO intensive applications, can show significant deceleration with all Intel-based processors. Here, you might want to consider the relationship between possible security risk and speed loss.
The above was explained by Microsoft that pre-Windows 10 pre-system systems are more likely to use system calls, meaning they are better understood if disadvantages occur in this connection. The other reason is around Intel's home, due to Skylake's more advanced architecture - speculative implementation can be much more controllable - with a modest performance punch over the repair tsunami.
It is also important to note that the KB4056892 cumulative update (which would solve the Specter / Meltdown problem) AMD machines showed severe side effects and was recalled temporarily. According to the news, the main subject is the K8 architecture, Athlon 64 and Athlon 64 FX.
