Not So Great News For INTEL CPUS

[txnetcop]

Once the fix is in place it could slow your processing speed up to 30%. This applies to Intel units for up to a decade ago...

Yikes!.......

[Loerch]

The good news is that games (like P3D, FSX, DCS, ...) will probably not be affected this much.
https://www.phoronix.com/scan.php?pa...l-Gaming-Tests has some benchmarks running Linux and https://www.computerbase.de/2018-01/...erheitsluecke/ has some similar graphics if you scroll down a bit.
Anyway, this is a major security flaw these are major security flaws and it is probably a good idea to install the upcoming patches.

It mostly applies to those who do heavy movie, photo, and streaming processes...

According to Google's research, AMD processors are vulnerable too.

AMD sounds calm and reassuring so far... https://www.amd.com/en/corporate/speculative-execution

So AMD is calling it "industry collaboration".....

[boxcar]

Yeah, they've blasted back at Intel, yet have changed their tune a tad to effectively admit that there could be a problem. The more I read about this then all the more disturbing it is becoming.

As Ted aptly indicates, gamers are likely not to feel the full wrath of this issue regarding the slowing down of their computers after patching, whenever that will happen, but as the above linked article strongly suggests: AMD is far from being out of the clear yet. Most troubling thing to me is that Intel is basically clamming up about this extreme vulerability... and other articles published today indicate this "speculative execution" security problem effectively includes all Intel processors going back 20 years or more.


May have picked the wrong day to have finally decided just what my next flight-simming computer build will be after weeks of researching. May drag my feet another week or two and see what happens.

Boxcar, it seems this will not affect gaming...besides truth be known every CPU has some security flaws and they are exploited every day. You simply keep a good firewall and antivirus active and it would not hurt to use a good VPN when searching on the Internet. After a 20 year career with a software company I took a job with TechCorp that used to test computer parts for DELL Computers. We always found security issues but that was not a big deal back in the early 2000s. It is today because of Ransomware but again do the above and you should stay out of trouble.

I note Intel has released a detection tool so you can see if your CPU is affected: -

It seems the i7 4790K in my machine is not vulnerable according to the detection test.

Sorry, but your link is for the Intel-SA-00086 vulnerability related to their Management Engine Firmware (as revealed last month). Intel-SA-00086 has nothing to do with the current kernel bug of this discussion. This link should NOT be used to determine vulnerability to this bug... virtually all Intel CPU's from the last decade are vulnerable to the kernel bug in the news the past few days.

Ashame that AMD is in denial mode....

Indeed Greg, your are correct!

Should have read all the comments in the linked video, and checked it out properly myself!

Must admit, I was a bit confused with the result, given that all Intel CPUs from a specific time period are supposed to be vulnerable!

You’re not alone, Paul. Because of how the principles are handling the situation a lot of us are confused.

I guess I'll just adopt my wait and see policy.
Life's too short.

Yes.
You will see new processor designs from BOTH INTEL and AMD.

[txnetcop]

What is disturbing is they will have to come up with a new kernel and a new way of accessing it and that could bring some compatibility issues
