Not a very good fix if the fix will reduce performance by 34% 

 

 

Lets wait until some real world testing has been done. With normal every day software and work flows. Not specialized test to exaggerate flaws.

It's a fundamental change on how the OS/CPU handles memory. There isn't really anything that can be done on current hardware. (There's no way to patch this via CPU microcode)

 

 

As for the impact, websites that run any javascript in your browser are able to read memory from any other process on your computer. Which includes being able to steal things like passwords, bitcoin wallets, keys, etcetc.

 

 

All you can do as an average user is install the patch. (Microsoft is releasing a hotpatch for windows 10 today and win7/8.1 on patch Tuesday. If you run any linux servers, you need to update the kernel. OS X is supposedly already patched with 10.13.2?)

I wander why it took 10 years to discover..

 

I wander why they don't just leave it unpatched if the performance hit will be so big..

I am still on MacOS 10.12 and have no updates pending, so I am assuming that the patch has only been released for 10.13? I was hoping to avoid upgrading, but it looks like I might not have a choice.

You install the update. There is no hardware fix for this and there won't be for 18+ months.

 18 + months really?

 

That mean's if Intel release a new CPU next 12-18 months it will also have the bug..

How is this not already a class action lawsuit?

 

 

Against who? And for what?

 

A problem has been identified, and is being fixed.

 

 

 

 

Are you being serious? Against Intel for a bug which cannot be fixed without a performance hit. 

 

Would you be so cavalier if you bought a car for 50K 2 weeks ago, and the manufacturer said they discovered a bug that couldn't be fixed properly, but as a work around it would stop the car reaching 100KM/h? To make it worse, they couldn't tell you yet how much slower you would be allowed to go, but the potential range was a max speed of 66KM/h through to 92KM/h?

 

 

 

Nope, I didn't think so.

Is this a warranty issue? Should affected CPUs be replaced by Intel?

It is much more likely that Intel will settle this out of court and people will be able to get a designated amount. I would suggest they will get extensive testing done, and work out the average affected performance hit, then add a 5% penalty and use that to calculate the settlement amount based on that.

 

I agree that the CEO pulling his shares out is extremely suspicious, I expect an investigation to occur and a significant fine to be handed out.

It takes a long time to design CPU's, even if they're just iterations.

 

This was privately disclosed ~6-7 months ago and it takes years to design CPU and get them to retail.
