Which CPU models? Will the 8.1 also receive an update?

 

I suppose it is related to servers anyway more detailed infos would be useful.

 

AMD not affected according to source. Some more latest news:

Huge Intel CPU Bug Allegedly Causes Kernel Memory Leak With Up To 30% Performance Hit
Read more at https://hothardware.com/news/intel-...ation-linux-windows-macos#gqCckUBCAmdeAUhI.99

 

"It is understood the bug is present in modern Intel processors produced in the past decade."

 

5-30% performance hit to patch it. I don't really need that to be fixed - don't care. Certainly not worth a 5-30% performance hit!

 

If it becomes an issue I am sure there will be large class action lawsuits and recalls to replace them. Intel will have to make good on their processors or they will lose A LOT of business and fold

 

go intel \m/ lol

 

Pentium rounding bug revisited lol

 

So, to fix the issue, do you think that they will release a WINDOWS hotfix patch e.g. "KBxxxxxx"? If so, maybe we could just uninstall the patch. Or, maybe someone will write a batch file so that WIN never applies the fix.

 

Audio computers should be run offline, so is it really a problem for us?

If I ever go online with my main audio computer, I use a version of Linux which is installed on a very fast USB memory stick, or I just use my Android tablet.

And I also have an old beaten up laptop for downloading and stuff.

I learned long ago to separate everything out

i agree stay off line with the workhorse ;) if you are on windows anyway....I never go online with my main workstation... it is AMD Ryzen untill i upgrade to the Thread Ripper maybe ;) was using Intel 5820K untill this years Ryzen build... but my online machine is the intel now lol... this is serious problem for intel tho >>>thanks for the post on this i had no idea \m/ also i have all my CPU's benched so will see if they take a hit haha......

What about Pinnacle Ridge? ;) It is said to use GF 12nm LPP (leading performance node) compared to Raven Ridge's (I meant summit ridge's :D somehow it didn't save edit ) "mobile" 14LP (low power node) So there could be some much needed clock improvements and minor IPC improvements. It would also be quite cheap upgrade path.

Yes it is a very good point to my next upgrade >>>im waiting to see what happens in this next month >>>ive been reading on the Pinnacle Ridge... i personally have been an Intel user for most of my musical career untill this past year building the Ryzen 1800x... Ryzen has gottin alot of flac from users but i love mine not had any issues with it at all... I built it on an MSI board loaded with a good GPU, PCI SSD's and 32gb of memory ... it replaced my intel setup with ease for half the cost ;)

 

Oh I can definitely hear a class action lawsuit rustling in the undergrowth.

 

Unable to be fixed by an microCode Update. Os vendors must patch a
Kernel level Design Flaw, with a high potential for a Performance loss, Per Chip Family.

Update:
some pre linux benches

So far no news on Amd

Yep - looks like time to switch from Mac to PC.

 

OK. The issue is hardware related irrelevant of the OS.

I can explain the Windows issue. The kernel, the innermost part of the OS, is supposed to run in a sealed-off, separate part of the architecture that can’t be got at or compromised in any way. There’s a flaw in an entire generation of Intel processors that allows a hostile actor to get into the kernel memory space. There’s indications that some ARM chips are going to get some kind of patch too. AMD processors are thought not to be affected.

A proposed patch in the software of the kernel is thought to mitigate the issue. The performance hit comes everywhere code in user space make an OS call to the Kernel. Software that makes many calls into the kernel, for example when accessing files or the network will be hit most. Software that overwhelmingly relies on raw cpu performance such as audio ‘might’ be affected less than software such as say databases. There may be an issue with software that makes extended use of virtual memory access.

It looks like M$ is putting out a fix in a near-horizon patch Tuesday whether you want it or not. As a vulnerability, it exposes a computer to the root-kit from hell as it would exist within the kernel space and become effectively untouchable and undetectable. So, you can get patched or you run the risk of the slags getting you running Bitcoin miners for them.

its an intel issue? possibly amd too
if it was a joke...Right on
