Intel Releases CPU Benchmarks with Meltdown and Spectre Mitigations

[bug]

Are there any benchmarks with older CPUs (Haswell, Sandy Bridge, etc)?

21% less responsive for Skylakes. That's definitely noticeable. Cr*p.

Aren't you the badass. Betting your next post will be "OMG my pc got exploited because of meltdown intel is teh evil no of course it's not my fault that i didn't install the mitigation because i'm a moron".

The only moron here is you. There are no known exploits for this vulnerability so the only thing you get from installing this patch right now is degraded performance, nothing more, nothing less. If you chose to willfully install a piece of software that reduces the performance of your CPU and offers no security benefit as there is nothing out there that it could stop, then that is your choice and I respect it as moronic as it might be. Please let me chose what I install on my PC, as I have been doing for many years with good results, without calling me any names.

There are no known exploits for this vulnerability

People keep saying this. That's almost certainly not true anymore given open source expoit examples have been published. The world moves fast.

No one here is a moron. Not installing these updates is foolish in most instances however.

Foolish because of what? The things you imagine might be true, the things that could have been invented, the color of the sun as it sets down over the ocean? In the real world this update makes your CPU slower, this is a fact backed up with real data, not emotion and fairy tales. Another cold fact is that there isn't one documented instance in which this vulnerability has been used to take over a system without prior consent of the owner or in any other way that was not just a test. So where is the threat, aside from your own imagination, where is real data? I have seen people work for weeks at a time, to get 5% more processing power from their CPU with overclocking, wasting time to do numerous tests and tweaking and here you are calling me foolish because I don't want to install a piece of software that can degrade my CPU performance with as much as 30% because something, somewhere, while floating over the rainbow, in certain circumstances could somehow use this to infect my computer...

The piece that you're missing is there is no documented attack till now, because the vulnerability itself has been undisclosed. Now that the cat's out of the bag, any unpatched system becomes fair game.
Sure, this isn't something a script kiddie could exploit, that much is true.

What about VM testing. Since that is where the hit is presumably the largest

Really really bad.

This is just Moores law.

The chipmakers "knew"

Looks like google knew before the makers..

Now with everything at all time high.
Some thing big will happen force people to buy new.
Run the latest tech fork out a mint.

Its all about "More" for the companies to make "More" profit.

Is Itanium effected?
And powerpc?

I so I am amazed intel isnt flogged a dead horse IItanium. Then again this would piss off most of there other users and admit fault.
and IBM hasn't ramped up there advertising

Wasn't Microsoft going to Arm severs?
