Intel cpu bug fix will slow intel processors down
 
A serious design flaw in "all modern" Intel cpu's has been discovered.
It potentially allows access to what should be protected kernel memory.
All the vendors are rushing to patch the bug soon, but the fix will slow
down the systems by as much as 20% or more. The bug shows up in context
switching. Details are still proprietary, but here's useful info.

In today's (Friday 5th Jan) Telegraph I read something like "MS have
already issued updates and more expected shortly." Last night I note) I
had a '2018-01 Cumulative Update for Windows 10 Version 1703 for
x64-based Systems (KB4056891)'. Run winver says I am on version 1703
15063.580.

Q1: There's no explicit reference to it so presumably that WU did not
include any fix for this major flaw?
Q2: Has there been an update for other users that *does*?
Q3: Anyone know when we can expect to get confident indications of the
performance impact for desktop PC users, of various types.

I'm apprehensive that my 18 month old i7 6700K (4.0GHz) will shortly
become some 25% slower on this Win 10 Pro PC.

perhaps they want us to buy into new equipment?

The issue is only a major issue on servers running a lot of processes
and virtual machines. On a standard desktop PC, they are talking about a
most a 5% performance hit in certain games, that's all. Still kinda bad,
but not as bad.

Hey Yousuf,

Is this bad for you?

We are certainly horrified to read such things in our papers but you
must be immune to these things.
