Intel CPUS?

[RAM555789]

So I heard about the Intel CPU bug and all, looked up what was suppose to happen and all with the performance drop, but I've been outta the loop for a little bit now, so 1.Has the update to fix this kernel bug on Intel CPUs been released yet, and 2.What kind of performance impact is it actually having on gamers?

[Anghammarad]

MS has pushed the fixes out already for Windows 7 - 10.

 

As for lost performance, in some cases (I only read about it on other IT sites) the impact could be as high as 30% of your known CPU power, depending on the architecture. 

 

From what is written, Haswell has the biggest impact. 

 

I currently run Ivy bridge on my main systems and don't feel any difference. The living room machine is Haswell, but that only is a kind of server machine and doesn't need high end performance. Haven't benched it after it got upgraded so can't really tell myself.

Yes, Windows has released a patch for this, There are hardware level patches in the works for it as well. For gamers there's virtually no impact. Even for most home media producers there will be almost 0 impact. The main point of impact is at high end enterprise level.

Please remove the "Could be higher than" part. That's been completely disproved for about 99% of cases. Most use cases, there's close enough to no change to make a difference.

Yeah most impacts are closer to 5-10% max.

Where are you seeing that? Most of the benchmarks (Other than pure storage benchmarks) have shown probably <1% change.

here on the intel post-patch performance results, though they may have improved after that. And I was talking about the worst case scenario

Fair enough. This is probably a worst case scenario kind of run just as a CYA.

Thats what I figured. I have a 4690k and havent noticed any performance hit whatsoever

BAMF!
