Any statement from Intel, or any other chip manufacturer regarding the
performance impact of these fixes should be viewed with a healthy dose
of skepticism. These companies have an interest in downplaying the
impact of these exploits/fixes to protect their stock prices.
I would believe the performance of 3rd-party companies who have measured
the performance, like RHEL who support multiple processor vendors (AMD,
Intel, etc.), and have less interest in a specific processor selling
better or worse. I would believe these numbers from RHEL more than I
would those from Intel:

According to several articles I read today:

Spectre (2 different exploits) affects just about every
processor on
the planet.
This is correct, and the other key difference is that so far
there is
only a solution to Meltdown.
The below linked page has this to say about Spectre:
"As it is not easy to fix, it will haunt us for quite some time"
Fedora has linked to this page for more info on the two:
https://spectreattack.com/
I haven't checked out that link yet, but from what I read, spectre
is also much harder to exploit, too, which mitigates the risk of
spectre to some extent.
