Id rather have the vulnerability than the performance loss (on my gaming rig).

hmm although I'm AMD user I don't trust in this info at all 😉

Well...shit Intel, I guess it's like the saying "when it rains, it pours". 😳

What performance drops does the news article (here) talk about? I don't understand.
It's pretty poorly written. First it talks about some security hole in Intel CPUs, and suddenly is on about some performance. What's the context?

I read now that Gaming Performance isn't affected.

How many Intel CPU,s will the effect and how far back, Some users are not going to be happy after spending a lot of money on high end Intel systems only to loose the performance they paid for.
As long as Gaming isn't effected (fingers crossed) it will not cause me a problem as my system is mainly used for gaming

For those wondering, it seems that CPUs supporting PCID will suffer less of a perf impact. From what I could find out, Sandy Bridge is the first architecture to support PCID. Westmere and older do not, and thus the perf hit will be bigger there.
However, I wasn't able to 100% verify that Sandy Bridge is indeed the oldest architecture to support this, or whether it supports it in a form that is usable for this case.

I wish there was a third viable option for PC gaming CPUs.

From what i've read, this seems to be a CPU Bug, specifically problematic for VM's.
If you have multiple VM's on a single hardware server, they can read-write between the VM's.
i.e. One VM can access the data of another VM on the server, without you knowing, or allowing it.
That is why it is such a Big problem for Amazon, Google, and all the other Cloud providers.

They will find a way, they always do, remember the line "Its impossible to code games to use more than a single core".

not too surprising. the patch impacts I/O heavily.
