Intel silicon bug to affect VM SH3?
 

With the recent announcement that an Intel hardware issue requires a software workaround causing a potential 5-30% performance drop, I wonder how many non-PC/server devices will also be hit by this rather massive bug. Take for example the SH3 which uses what is essentially an Intel Atom processor which I believe is also one of the models affected.

This could get messy!

You must be aware of how "quickly" VM update their hubs with security patches.

The intel fan boys are not going to be happy when the AMD fan boys start sniping :)

Re: Intel silicon bug to affect VM SH3?
 

Bound to happen. I've never used Intel always AMD because it works for me. Doesn't mean I'M a fanboy, I let others do that type of carp.

Last Intel PC i had was a P133mhz lol.

Re: Intel silicon bug to affect VM SH3?
 

Like the hub 3 chip needs anymore issue!

Re: Intel silicon bug to affect VM SH3?
 

Wow that is very fast PC :-)

Re: Intel silicon bug to affect VM SH3?
 

Looks like some AMD chips could also have weaknesses in the same sort of arena.

I knew there was a reason I liked SPARC.

Re: Intel silicon bug to affect VM SH3?
 

The meltdown bug only affects intel (which is fixed by slowing down the OS in certain cases). The spectre bug affects both. But it isn't clear how to fix spectre yet.

Re: Intel silicon bug to affect VM SH3?
 

The fix isnt to slow things down, the slowness is a side effect of the fix.

Carl just posted this Chrome temporary fix on FB.

Re: Intel silicon bug to affect VM SH3?
 

This is unrelated and would not help this particular problem.

Re: Intel silicon bug to affect VM SH3?
 

I doubt there'll be a patch to fix this on embedded hardware, given there's not supposed to be a way of running code ON that hardware.

Re: Intel silicon bug to affect VM SH3?
 

It may not be related to the Hub3 question but it is very related to the Spectre issue.

Firefox was also patched in the 57.0.4 release.

Well this was never really the claim. The 30% thing comes from cases where the computer is reading hard drives in tiny intervals constantly. Which the average user is unlikely to do. It could be detrimental to datacentres who purchase huge amounts of CPUs and ultimately affect the price.

Re: Intel silicon bug to affect VM SH3?
 

I wonder if datacenters will switch to AMD now.

Re: Intel silicon bug to affect VM SH3?
 

The ponit of mentioning the 30% for users was because sensationalism sells.

Re: Intel silicon bug to affect VM SH3?
 

There are reports that computers running intel with Windows 7,8.1will see the greatest % hit as well as intel Haswell and earlier cpus.

Nvidia have just released drivers in support of the issues. http://www.tomshardware.co.uk/nvidia...ews-57697.html

It would be nice to have a single thread on this meltdown, spectre issue as it affects so many different products.

Re: Intel silicon bug to affect VM SH3?
 

Highly unlikely, that would cost far too much, and affect performance.

Besides which AMD are affected by one of the two issues anyway.

Re: Intel silicon bug to affect VM SH3?
 

Well they are unlikely to replace existing machines, but they may start purchasing AMD for new machines.

Re: Intel silicon bug to affect VM SH3?
 

Now or in the process of being mitagated.
