>If taking a look at the geometric mean across the dozens of benchmarks carried out, both the Core i5 8400 and i5 9400F basically have around 18% lower performance from these default/out-of-the-box mitigations on Linux systems for Meltdown, Spectre, L1TF/Foreshadow, and MDS/Zombieload.
>18% lower performance
>18%
Thats probably around Ivy Bridge / Haswell tier performance. In 2019. Intel BTFO.

Then what is the performance hit for Ivy? Asking for myself.
IT'S A LIEEEEEEEEEEEEEEEEEEEE
Probably the same -18%. Could put it at Nehalem/Westmere performance I think.
>Nehalem/Westmere performance
YIKES
Intel status: M I T I G A T E D
Well, at least I do not do CPU intensive tasks.
Actually -18% would put Ivy Bridge somewhere between Penryn and Nehalem. Thats 2008 performance level.
This is probably the biggest x86-64 security disaster in the history of CPUs.
>18% performance lost forever
holy shit, this is class action suit level stuff
intelcucks enternally BTFO
Eager to know how they're gonna fuck up their 10nm lineup
Time for more lies and bribes
imagine how I feel having a haswell CPU
imagine how i feel having a sandy bridge CPU
Imagine how I feel having i5-2400

Literally doesn't matter. Majority of people won't even need to apply these patches. Who the fuck will even bother to hack you pathetic neets? Oh no, muh patches! Boo fucking hoo. Intel+nvidia is still at the top. Amd will be bankrupt within a few years. There's a reason google chose intel+nvidia for stadia. There's a reason why the newest mac has intel+nvidia. amd is utter shit. Cope harder.

Huh? Isnt Stadia using AMD GPU?
yes both of what mentioned uses AMD GPUs. dont fall for low quality bait like this
I don't need these patches because I don't keep information on my computer. It's why I don't even like password managers.
HOWEVER, did you consider the hundreds of millions of data centers who have to keep top secret information on their servers? People who don't have the luxury of keeping passwords on a notepad, or have to constantly perform bank transactions? They're gonna be hit the hardest by this, and the effects are cumulative, if not multiplicative. Imagine a server just barely at capacity with like 100 intel chips. Now imagine losing 40% of that performance. You're essentially down to 60 intel chips' worth of power. You think that's gonna make anyone happy?
Intel will probably bribe a few people and pretend this never happened, but the wonderful thing is that they keep screwing up, so they don't have the excuse of it being a single isolated incident.
>google chose intel+nvidia for stadia
>amd will go bankrupt
>incel lake mitigations meme
i cant tell if you're trolling or not
Is there any way to remove all these patches? I do not care for security, I use the computer only for games, porn and chans.
yes, kill yourself
or append these to kernel parameters
noibrs noibpb nopti nospectre_v1 nospectre_v2 l1tf=off nospec_store_bypass_disable no_stf_barrier mds=off mitigations=off
And on Windows?
Call MS tech support.
>There's a reason why the newest mac has intel+nvidia
but it has intel + amd because nvidia jewed apple before.
He just copy pasted the post above his, doofus
Delete pls sir
Lucky I don't use Linux then. Seeing as OPs 18% is about Linux.
Now another 18%
H O L O C A U S T E D
I disabled mitigations and saw a 1.8 percent benchmark increase
it's all registry settings, you need 2 iirc to disable all mitigations, and they are near the end of this page
support.microsoft.com
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverride /t REG_DWORD /d 3 /f
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverrideMask /t REG_DWORD /d 3 /f
(note the inspectre gui tool sets the same keys)
Doubt it is as high as 18% especially for haswell. Ivy lack INVPCID so it suffers more on Meltdown patch, but Haswell has it. Newer Skylake and above cannot use retpoline alone in Windows/Linux and requires IBPB as well. On older systems retpoline alone is enough.
Now the 2700k threads can finally fucking die.
iirc, the spectre/meltdown patches had a higher performance hit in windows than in linux, so expect the same this time around.
>he fell for the mitigations meme
I bet you install microcode updates too.
>teleports behind mitigations
noibrs noibpb nopti nospectre_v2 nospectre_v1 l1tf=off nospec_store_bypass_disable no_stf_barrier mds=off mitigations=off
Heh, nothin' personal, kid.
Who wants to play the stepping lottery?
>It shows that the 9400F can come in 2 flavours, a Intel64 Family 6 Model 158 Stepping 12 and a Intel64 Family 6 Model 158 Stepping 13, where the "Model 12" doesn't have the hardware mitigations in the same fashion as Cascade Lake has, but the "Model 13" does have full H/W mitigations.
so model 12s are leftover 8000 series?
Does it affect windows or linux only?
I thought Sandy Bridge was like a 20-30% jump over Nehalem. Current CPUs would go back to around Haswell, but Haswell wouldn't go back to before Sandy Bridge.
Probably?
It's a flaw in the processor, OS is irrelevant.
lol
Any word on Mac impact? I'm trying to convince my boss to get a Windows box or even a Ryzen Hackintosh instead of a new 2018 iMac/Mac Mini.
There is a single switch for that, retard.
It's a problem with CPU, not OS.
Imagine cucking your pc to a planned obsolescence manufactured 'flaws' to make up for no improvement in the cpu market for a decade
Lol absolute state of u
Lol intel is rekt
If I were to buy one of these chips how would I turn off the security patches?
Very carefully
Yes, but the patch will be applied to the OS, no? So the impact could vary.
Intel is the nigger of CPUs, runs faster but it's extremely pozzed.
Nah, Intel users won't do anything. We've been telling them for years and they just don't care.
Don't worry about it, live on brah.
You'd have to modify a few registry entries on windows, and use the following kernel arguments for GNU/Linux
>mfw 2670qm + gentoo
Intel have suckered a load of their customers who were expecting hi-spec chips fast horses and got sold slow-tier chip lame mules. And vandalized their customers computers with patches.
Why aren't Intel being sued off the Earth by class actions. Or facing mass refunds for turning their own customers into victims?
P.S. going AMD, personally.
What kind of retard installs a patch that reduces performance by 18%? I'll take my chances, retards.
Good gweilo
Are people on Windows 10 Pro getting these mitigations by default? Is there some way to check if they're installed and enabled?
A-Asking for a friend~
I know for sure the HT mitigation is not forced down your throat
No... just Intel.
Maybe 1.7%
>CPU:
>Dual Core: Intel Core i5 M 520 type: MT MCP speed: 1463 MHz min/max: 1199/2400 MHz
THANKS INTEL!

They will still keep making shill threads though.
I HURT MYSELF TODAY
TO SEE IF I STILL FEEL
I FOCUS ON THE PAIN
THE ONLY THING THAT'S REAL
if nvidia got a class action suit for the 3.5gb thing surely intel could be sued for this right?
THE NEEDLE TEARS A HOLE
Not in stable distros yet.
This is extremely satisfying to watch after putting up with almost a decade of Intel jewing everyone.
THE OLD FAMILIAR STING
TRY TO KILL IT ALL AWAY
BUT I REMEMBER EVERYTHING
Stop with this antisemitism
Who cares about security?
Weird that the Jews aren't doing a shady smear campaign like they did years ago when spectre was fresh.
Anybody remembers that?
This seems bigger and yet they are quiet.
The only silent Jew You could trust is one that's been gassed.
I also have an i5 2400. How fucked are we, bro? My Debian install has been getting slow as shit lately. Thinking about taking the risks disabling all the patches in GRUB. My PC is like 10% faster compiling software when I used "nopti".
Oh they're trying really hard. See image
System startup time is worse now, went from roughly 20-30 seconds to almost one minute, other programs also take a bit longer to open, my SSD is fucking crippled
Holy fuck the comments on that article are an even better read.
>Intel knew they'd need to respin these CPUs. But they didn't change the SKU, so the name is the same. No bulk retailer is likely to tell you what stepping they're offering. You have to have the CPU in your hands to know how the mitigations are implemented, and the resulting performance.
>You have to have the CPU in your hands to know how the mitigations are implemented
Big OOF
What if Intel really abandons desktop CPUs
Imagine how I feel with an Ivy Bridge.
Never buying Intel again.
Then be ready to spend $500 for an entry level Ryzen.
AMD are gonna take a dump on their server space as well
Intel don’t have consoles, don’t have desktops and soon won’t have servers
The only thing Intel has left is laptops.
Bullshit
