My take on Intel refuse to patch the bug.

Apparently we all know that intel Chips (all the modern chips that are produced in the last 10 years) have a bug that skips some security checks to improve performance. Basically it checks 999 out of 1000 checks to save time so it can improve performance. Fixing this can cause intel Chips to slowdown as much as 35% And apparently intel is refusing to fix it via a bios update. 
 
So yea intel is refusing to fix the bug saying it cannot be fixed by a bios update and can only be fixed via a software OS level update. The solution is a kernel table isolation patch which separates the kernel memory from the user processes providing kernel overhead. This unfortunately will results in slowing down the system by as much as 35% (5% ~ 35%)
 
My take on this is, this bug can be fixed via a simple bios update and intel is only refusing to do that is cause then the only systems that are effected by this will be intel CPU's, apparently we all know that AMD does not suffer from this bug but a os level update can and will bring down the AMD systems along with Intel systems. 
 
I think intel is deliberately doing this so as to bring down AMD along with it. 

Microsoft in there infinite wisdom have decided to impose a VRAM cap for games the that use DX9 o.O. May God Bless them those whoever came up with that idea. :dry:

AMD has opted out of being targeted by the patches that are being ported to Linux to patch this bug. 

 

One would assume that they've done the same for Windows as well. 

 

This really deserves to be on the thread for this topic in Tech News, not as a separate thread.

I've more or less only heard of this today but its only effecting certain tasks, no?  Not the rntire system.

Want to custom loop?  Ask me more if you are curious

Mostly I/O and Memory based tasks. 

 

IO is by far where it hits the hardest.

Could you do a quick explain like I'm 5 for this situation? Just woke up and haven't had my coffee yet.

That depends, but it's going to effect I/O tasks and networking, requesting and accepting data. Its still unknown as of how this is going to effect normal person who just uses it to play games and watch youtube but well video encoding, sound processing, running virtual machines and other such stuff are going to take a hit.

Well lets hope they did, i myself have personally bought an Intel CPU so its not like i am rooting for AMD.  But its wrong like punishing an innocent for a crime he have not done. Also am pretty new to forums so apologizes for posting it on wrong topic if i did

No they aren't. It's not a bug that can be fixed with a microcode-update.

Well am sure it can be. I am an application developer and when something can be fixed via OS level patch then am sure as hell that it can be fixed with a microcode update.

Looking to raise your posts count? There is already a topic on the tech news where you could've wrote down your take and maybe read some of the replies and see that it cannot be solved through a bios update.

Any reason to just not patch It?

Aside the fact the greatest majority of mainstream applications will most likely only see a hit of 0% ~ 5% the huge issue is for the enterprise level as they shown cloud services and what not... your mainstream CPU specially if Coffee Lake will be mostly fine thanks to PCID.

Hold on.. wait .. i never said i am MORE knowledgeable than Linux Kernel devs wth...  I just said that i am a application developer and i know how some stuff works. 

You being an application-developer has no bearing on this, as e.g. the following quote shows you have no idea what you're talking about:

I think intel is deliberately doing this so as to bring down AMD along with it. 

There is no reason for why the OS-level fix couldn't be made so that it only affects Intel-systems. I mean, all modern OSes set a whole bunch of different kinds of flags that direct its internal operations based on what CPUID they read and just as well the workaround for this bug can be turned on/off with a simple "if(cpuManufacturer == Intel) enableWorkaround = true;"

No noticeable changes for gaming though

Isn't the microcode update limited to 1kB ? Can everything be fixed with 1kB ?

Looks like Windows has enabled KPTI for AMD processors too, so expect a performance drop with AMD on Windows as well.

 

 

This ... Exactly this is what i have been worried about...  Thank you for pointing it out 

Microsoft in there infinite wisdom have decided to impose a VRAM cap for games the that use DX9 o.O. May God Bless them those whoever came up with that idea. :dry:

I am not sure really but in the software field there is always a way. it all depends on how willing you are to solve the problem :).

I'm super pissed as I'm sure all of the Intel owners are. The last part for my first rig ever is arriving tomorrow, and I already have the 8600k in storage. Does anyone know if the performance loss caused by the patch will ever be fixed, if it even can be fixed?
