A fundamental design flaw in Intel's processor chips has forced a significant redesign of the Linux and Windows kernels to defang the chip-level security bug.

Programmers are scrambling to overhaul the open-source Linux kernel's virtual memory system. Meanwhile, Microsoft is expected to publicly introduce the necessary changes to its Windows operating system in an upcoming Patch Tuesday: these changes were seeded to beta testers running fast-ring Windows Insider builds in November and December.

Crucially, these updates to both Linux and Windows will incur a performance hit on Intel products. The effects are still being benchmarked, however we're looking at a ballpark figure of five to 30 per cent slow down, depending on the task and the processor model. More recent Intel chips have features – such as PCID – to reduce the performance hit. Your mileage may vary.

well f*** me sideways...

 

in order to upgrade to a newer hardware without this issue would also require me to update to a new chipset....

 

AMD is not looking bad at all at this point.

I don't think it will make much difference to our cpu though. We'll see

I think the newer CPU's are better off and probably wont surpass that 5%, but if you have an Ivy bridge (like me) or other old stuffs you might not be so lucky. Those older CPU's might really take a noticable hit. 

 

The fact they everything is hush hush and nda and whatnot makes me think its pretty damn big. Server farms and whatnot are, and will not be very happy.

Was just reading about this heh.. Intel CEO getting rid of all possible shares before it became general knowledge feels very reassuring... lol

It looks unlikely that those of us who primarily use our machines for gaming will be noticeably affected - I am concerned for my clients who have a mixture of dedicated and shared cloud environments but I'm still waiting to hear what the impact is likely to be for infrastructures based primarily on VMware, although I should know more tomorrow.

I heard the patch to fix this is called KB4054022.

 

Not really solid on that yet tho, can anyone confirm?

Seems like it won't be that bad for performance.

Spoiler

Also both Google and Amazon are saying that they don't see any big hits to performance.

But we'll have to wait a few days until we know for sure.
