My take on Intel refuse to patch the bug.

[LAwLz]

@DeadlyTitan You have no idea what you're talking about. Your entire post is based on a bunch of misinformation.

I wish people would stop spreading misinformation.

Security > Performance, do the patch... the more we have learned on the subject the more we realized the performance hit to normal folk will be minimal, enough to ignore the entire drama... certainly gonna hit some enterprise level business hard specially virtualization scenarios but people looking into content creation, gaming & streaming and what not this is painting out to be completely harmless.

Just watch a video on the exploit.  

 

 

Apparently the fix does not have any impact on games and general workstation tasks (raw compute like blender etc).

 

However this is a massive deal for networks and servers.

 

Sure it will be rolled out like all the other windows patches. 

 

Strange how this comes to life as Intel's new CPU's do this memory checking differently now and are far less affected.

AMD processors also have similar design flaws that needs the Patch, the difference is that Intel has it worse.

 

Intel kernel flaw opens door for both Meltdown and Spectre exploits while AMD chips only opens door for the Spectre exploit, either ways both needs fixing:

Thank you! I was just talking about the meltdown exploit, but I'll look into the other.

Looks like everyday use and gaming will be unaffected ;

I have just bought an AMD ryzen processor and next week i will install windows 10.

Will the patch reduce my processor's speed 5-30% as happens at intel's speed?

unless you're doing high end workstation stuff or running VMs or servers, you're not going to feel the effects of it. people need to calm the hell down, it's not the end of the world.

 

any performance loss will be mitigated over time, this rush fix is just a temporary thing to patch the exploit, then they have time to create the work arounds which will alleviate the performance loss

its annoying, you know it.
Why the amd cpu is affected too by the patch?

its annoying how we're getting so many questions about the same stuff when the answer is in other threads, yes.

 

Because it's a change to the kernal of the operating system that the CPU needs to talk to, which isn't tied to the CPU make.

but how will people complain about the 30% now? geez, facts are such a buzzkill

this is from /g/ and it sums it up pre well

You forgot that Intel‘s new 10nm has been delayed as well.

 

Intel got comfortable in the lead and has been greedy and slacking. Looks like they will soon be starting to pay the price.

After what ive read here: http://nordic.businessinsider.com/intel-chip-bug-meltdown-and-spectre-explained-2018-1?r=US&IR=T

 

Meltdown is mostly exclusive to Intel. However Spectre is to both. Spectre is harder to pull of hence less of a panic. Spectre isnt expected to je fixed with this patch and requires it to be fixed at the processor level. Dont take my word though. Read it yourself and please point out any misstakes in my interpretation

No your performance will be the same it has always been, the patch only affects performance on very specific enterprise orientated workloads such as deep virtualization, data center and cloud solutions, people with common mainstream CPUs with PCID (any thing Sandy Bridge or newer) are not going to feel any bit of difference:

Logically this makes zero sense.

 

Given that this is a flaw in the speculative execution algorithms that were implemented supposedly back in the Pentium Pro when Intel first launched it and it took this long to figure out there was a problem with meant it was not obvious.

 

And there are plenty of cases were static analysis alone doesn't really paint the entire picture of how the system will behave. I found a bug in software at the last company I worked due to a design issue. A design made by rather smart people who did things like whip up an LTE system within months to replace a product that used an old and under-performing radio system for communication. And even then at first glance at the design document, I'd argue most people would think the design was fine. The flaw showed itself only after doing a corner case, which in all likelihood was not going to happen. And even then, there could've been five other things that were wrong before I got to the software itself. Investigating this problem took a better part of a half-year for what ended up being a relatively simple fix.

 

But eh, what do I know? I'm sure all the armchair computer engineers out there know better than me.

 

EDIT: The only way for the "greedy" argument to pass is if Intel knew about this flaw for years. But as it stands, they were made aware of it recently and it wasn't made public until just now because that's what you're supposed to do in the security community. You report it privately to the stakeholders so they can assess the situation and find a way to fix the problem. You don't just throw out an exploit and its details without giving a chance for the stakeholders to fix it.

 I wasn‘t talking about the bug specifically. I‘m adding to the „everything is fine“ statement and the grand scheme. I know the bug is not the result of what I said.

I think that says "everything is fire"

Hi, I have multiple PC and Laptops which are using Intel CPU. May I know how do I know if my CPU are affected by the leaks?

 

And if mine are affected, How do I fix them?

 

Thanks.

If they're 64-bit and newer than Core 2, then they're affected. It's that simple.

You install OS-updates. There is no other fix.

OS Updates? Do you mean Microsoft Windows Updates, Mac OS updates?

How do I know if Microsoft and Apple has released the updates?

Mine is 3615QM, 4790K and there is another with Dell Laptop with Intel's 7th Gen.

Yes, you just install latest updates. Microsoft is supposed to release the patch next week. I have no idea about Apple, I do not use any Apple-stuff.

I have read that the Patches would slower the CPUs. Is that true?

If you don't run virtual-machines, do heavy database-stuff or offer web-services for hundreds/thousands of people or similar heavy-duty stuff, then you have nothing to worry. Normal users and gamers shouldn't see much of any difference.

I do a lot of Chrome thing and similar which is very heavy. Like 50 + tabs or so sometimes.
