So many vulnerabilities that have come out over time and continue to come out that are Intel only, it just adds another reason for me to be glad that I chose AMD again for my new build.
I shudder to think of the presumable cumulative impact that all of the patches would have on performance.
It is doing wonders for Intel's economic performance. All those servers that dropped 40% in performance, now companies have to go out and buy 40% more Xeon servers to make up the shortfall. I couldn't make this stuff up.Originally Posted by Output
And no, they can't buy AMD servers, "we only buy Dell here".
Does anyone know of anyone in the private world, who has ever been "hacked" through any of these vulnerabilities?
There have been so many, over so long...what are the real world impacts of these?
Does my gran (not a real person) using her 3 year old PC run the risk of a good bank hack, if she obeys every other rule of internet safety? If she never clicks a link in an email, never falls for a phishing scam, never unzips a mystery attachment etc...is she at risk?
Yes, she would be at risk...
She goes to her favourite knitting website.
The website serves up an advert
Someone using the ad network serves up some javascript along with that picture of a kitten (awww).
Now when you log into something on another tab, they can read your password.
Updating your web browser fixes this. Keeping your OS up to date fixes this. Just let stuff update itself, and she will be fine. But it's these fly-by attacks that are the problem. Nothing is stored on the PC, so "my virus scanner didn't find anything" isn't surprising, but when some of these vulnerabilities are demonstrated with just javascript then you are wide open.
Which reminds me, I need to go around the house and update all the graphics drivers. I haven't verified the idea that webgl can access sensitive memory through shader programming, but why risk it.
Disabling hyperthreading ... essentially my i3 becomes a Celeron.
Another month another performance reducing intel flaw discovered..whoops
Sadly I can't say I'm too surprised.
With how good AMD's EPYC line was said to be over the past few years though, you'd think someone would be rethinking things - even if it was just Dell and similar companies rather than those buying from them.
I can only assume the thinking is "if they were any good, Dell/the others would be selling them too instead of only being Intel".
They get such huge deals there is no point going EPYCSadly I can't say I'm too surprised.

Old puter - still good enuff till I save some pennies!
Basically the old "competitive discounts"...
Yay... more performance nerfs incoming, assuming I even get the patch on my 4790k....
I'd already started saving for an upgrade but was hoping to hold off till desktop 'ryzen 4' but at this rate I might need to bite the bullet and get ryzen 3.
Was always going to happen, once a new attack vector is discovered people find different ways to exploit it. I've not read the article but just going on the name given to the vulnerability it's probably safe to assume it's related to how Spectre exploited the cache buy guesstimating what's stored in part of the shared memory it doesn't have direct access to.
These intel threats are paid for by AMD,,,,,
But that's also okay MMA enterprise rules have been the norm for a long time, so if you want to stay in the game, you have to play the game.
I'm in a similar position. I've noticed a severe drop in responsiveness since Spectre and Meltdown patching. Outright oomph seems mostly preserved but it's definitely an issue.
I think I may well just go and get Ryzen 3. My only real reservation was the price of the chipset and also the heat generated by the chipset. I buy for the long term and so I'd definitely want PCI-e 4 but I can't be dealing with chipsets which need active cooling. Seems like a recipe for premature failure.
At the moment I've been considering a bundle from OCUK. I suspect in a few years the many many cores will be made use of so I'm looking at 12 core Ryzen. Because I have absolutely no use for that kind of power. At all. Nothing. But I crave it.
It's like water-cooling. Put the money into a decent air cooling system and it'll be better...... buuuuuut....... "my PC has a radiator".
Your 4790k isn't even affected by this vulnerability
If you're talking about X570 I've had one for 4 months now and despite trying my damnedest to get the PCH fan to spin on a silent profile I've not managed it, iirc even using a performance profile it doesn't start spinning until 49°, balanced is 59°, and silent is 69° and even then it starts out pretty slow.
