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.

I could rewrite that part again. : Lol: Both Specters were affected by AMD, only Meltdown remained Intel.

Let's say the official stand for S2 was the explosion that they could not reproduce on AMD machines. Do you know that now?

Ed .: I can see it, it's about TPU.


Sorry, I forgot to link. It was the official announcement of AMD, it started out there.

Just a few additions:
- "AMD, according to our knowledge, only in the first" - as a clarification, I note it in Specter's first variant. I think this is a clarification because the list is first mentioned in Meltdown, where AMD is not concerned; and logically the numbered note would apply.
- "showed serious side effects on AMD machines" - Not all AMD machines, but only old systems (K8 and pre-machines). At least in several places, this information was shared - where it was not (for example, PCW) that part of the original reference was partially translated because the "some older" flagship was forgotten.

Anyway, I can imagine that MS will slow down the Win7 / 8 systems better. Just like and how you printed the Win10 so far, you can imagine anything like this ...

I've now run the MS forum, really 99% K8 owners complain.

Thanks, I changed it. :-)

The first grandmother came together to think that for the last minute, for the sake of duplication, I changed the two, I changed the sentence. In the AMD case, however, MS is rather narrow-minded, it does not exactly describe the affected procizions.

At Windows 7, I remembered that it was now a good deal for him ... : sad:


The AMD issue was perhaps first written on ph! There were rumors of older systems being written as a problematic system, then either in a different story or in the forum that the bad technical description criticized by MS is about the K8 and the stuff that it was before because it did not come from K10 fault.

Ed.: on ph! they write about K8 (the forums say K10 machines say they are all right), but on hwsw it was written that on the MS forum 10 yearly K8 machines reported bugs.
