All Intel CPUs in last 10 yrs have critical bug to show protected kernel memory areas

The patch doesn't affect AMD ( won't slow down AMD cpus) .expect AmD stock price to soar and intels to crash . Intel knew since November and CEO just lost all investors confidence
November article that makes sense now after we know what we know
https://finance.yahoo.com/news/intel-apos-ceo-just-sold-221000267.html

Class action lawsuit on the horizon...and they'll get to fight big names not a average joe
 
There are some indications that this might affect ARM as well. This is the only posting I've seen:

Good luck getting Android vendors to patch their shit. Here's the exploit clusterfuck that was just waiting to destroy Android as a secure platform.

Not to mention any performance hit would be pretty noticeable on a system running A53s as the PRIMARY processor.

Something is up and smells like a cover up , or market manipulation or overall a big mess up
If there was a problem and the patch fixed but the PC is slower users from this site or other enthusiast forums will figure it out. We have ppl that for 1% gain they shell hundreds of dollars...10% performance loss will be easy to spot

Too big to fail ....?
 
Intel's press release legitimately makes me ****ing furious... what a bunch of lying assholes..

Well, if the rumors are to be believed, Microsoft's patch just does the same thing for all processors, so expect a lawsuit from AMD for slowing down their processors to make Big Daddy Intel happy.
 
At least they said they're working to mitigate the performance impact. They could have just said "performance impact is minimal or non existant, so fuck you."

Since this mostly effects their enterprise business, you know they mean it.
 
Intel's press release is, technically speaking, completely correct. Proud work by their lawyers.

Its also woefully incomplete. As Intel states, the defect won't allow anyone to "corrupt, modify or delete" data (at least not directly). But it certainly can permit exposure of data from kernel memory, execution of malicious code "inside" the kernel and privilege escalation exploits. The great fear is the possibility that this defect may permit "Hypervisor Breakout" exploits - and the massive effort, identity of contributers and rapid commit of fixes to both the Linux and NT kernels suggests that this fear is well founded.

The belief has been that KVM and Xen have been reasonably immune from Hypervisor Breakout due to hardware virtualization assist has been the keystone of security at cloud providers. If this "truth" falls then Amazon, MS and Google have a massive problem on their hands.

Anyone can sign up for Windows Insider program and get the changes now if they are interested. Who is going first? :p

I'm on Windows Insider already. Unfortunately, my computer and I are separated by about 2300 miles and have been so for almost two months now. :mad:
 
Is there a way to block the update?

I want to keep every last bit of my performance.

10% performance hit will greatly fuck up emulator performance and Assassin's Creed Origins. THERE'S how it affects your average user here. Wii U games are going to go from being playable to slideshows.

It shouldn't affect gaming performance at all, you should be fine.

Fix is either change hardware or performance inhibiting code, this hurts intel in the very market they covet the most, servers, database, hosting and cloud centres. But at least they can still play games.

Except Assassin's Creed Origins is a double-DRM'd pile of shit that causes quad-core Intel CPUs to reach 100% usage.

And clearly you don't understand how emulation works. CPU performance is more critical than GPU performance for emulating console games. That extra 10-20% of extra performance you get out of having the latest Intel quad core CPU is the difference between playing The Legend of Zelda: The Breath of the Wild at a smooth and stable 60 FPS instead of a janky slowed down framerate. Cemu needs every ounce of CPU power possible.

Emulated console games make up a considerable portion of the PC's library. They are a staple in every PC gamer's roster.

I used those examples for a reason.

maybe not, looks like amd needs no software fix for hte type of protection needed that will affect performance, Linux jsut imposed a blanket protect being a small fry OS, MS have the ability to code exceptions

The performance loss in the patch is mostly felt in IO heavy applications. For mostly CPU heavy applications, the performance loss is very small. For AC:O, Computerbase saw a 3% loss at 1080 lowest preset with a 1080 Ti.

More than likely, CEMU will still be much faster on modern Intel processors than AMD ones.

Hmm thought Linus made an exception for AMD since it is an non issue for them.

The PTI is blanket but can be coded around to disable it for AMD systems, the effects of this blanket patch can have severe effects on AMD's performance in some instances so its likely something they need to address down the line to ensure AMD is not treated with the same brush as Intel.

I guess the silver lining in all this is while you game (may your frame rates be as high as your temps), someone is potentially stealing personal information from you to use for whatever they want when they want. But lets make this about gaming.

I'm not sure what your point is, this is with the Windows variant of the patch to fix the Intel vulnerability installed.

Windows 10 hasn't had a kernal patching yet, 1709 is basically just an anniversary edition update. And gaming is not affected, though things that actually make intel money are gravely affected.

And thats not even accounting for what running the insider ring may make of a difference. They can test today with the released patch on same versions of the OS without having to use the insider ring.

The site has published some notoriously wrong reviews (as demonstrated in other threads). It doesn't mean the place is wrong 100% of time. If you have some criticism on this review of the patched Windows, share it with us. ;)
 
So we get gaming benchmarks for a intrusion that affects system security? seems like a wonderful waste of time. Maybe benching enterprise security tests would be more feasible, demonstrations on how easy it is to break databases once information is stolen. This is not a performance issue, this is a security issue.

Since this patch will likely reduce Intel syscalls why not see how this affects databasing, but yay more game benchmarks

Do we get a show on the "some notoriously wrong benches" or do we assume this to be more bad feels man.

You're moving from the GPU limited to the CPU limited and you're starting to notice a 3-5% drop in FPS. Hardwareluxx showed the same stats with other games. It's the same argument that's been going around for a while. In GPU limited games, you can pretty much run any modern CPU. When you start to see a CPU bottleneck, Intel used to have a ~10% advantage, now it's down to ~5-7% with the fix.
 
I don't get why we have to have gaming benches for a security related threat, this needs to be demonstrated on database/SQL type benches.

In fairness, I don't get why a security patch has a 3-5% hit on gaming in CPU limited situations.

If i understand the patch can have upto curtailing syscalls but 50%, gaming is not very syscall heavy so the effects are low, but in the event of being a server system the effects could be somewhat catastrophic, if the server has to now use double the time to call, address and dump. If AMD's databasing performance was already damn good, I shudder to think what Intels results are like when they are doing up to 50% less work in a cycle.
