Okay, 19 time slower means what now? This is a language question since 2 times slower means twice the time needed, 19 times slower means 19 times the duration needed for calculations? That would be a huge hit... practically making the CPUs all but unsuable for such scenarios. If I understood this correctly.

Yeah, saw this on the Linux Newsfeed, wanted to share it here but I just ignore it. At this point, it's just beating a dead horse.
Don't get me wrong, I want all CPUs to be secure, regardless of brand, but it seems that's the price we pay for branch prediction or another way of data prediction, just to gain more computational speed.
It's the same triangle: performance security price choose 2 you can't have all 3.

Security people are ever the paranoid.
Enjoy life?
They are quite enjoying it, but making money in security field. But their way of enjoyment wildy varies from the average person.
Kaarme
It's their job. They do it to get money for watching beer, drinking movies, and lifing enjoyment.

Bring it on! With the world consumed by COVID 19, Intel vulnerabilities are more of a laughing matter now. Surprised anyone gives a crap anymore.

The problem here is that while gamers can skip all the patches, and they probably should if they are just gaming, enterprise just can't. If the microcode update are slower enough, that may be a problem for intel.

More performance reductions.
My 4770K... i mean Pentium 3 by now is ready!

AMD fires back boom! 😱

who needs security when you have all that speed?

My god, maybe with more 34 patches mine i9 can be beated by ryzen 3800x

I would argue you can't fully enjoy life if you live in fear. That doesn't mean you should be irresponsible about proper safety, but happiness is limited by those who have so little trust in others that they feel a need to sacrifice convenience and practicality in their personal lives. Sure, some people don't mind the inconveniences, and some no longer live in fear as a result of their added security. But the fact they have so little faith in humanity to bring them to such a point is still a bleak look at society.
In another perspective: I would feel safer to triple-lock my doors, arm myself everywhere I go, use a VPN, use 2-step authentication to unlock my phone, and encrypt the drives on all of my devices. But if I really felt the need to do such things, that should mean I have a good reason to believe harm will come to me. If that's the case, I'm either living in a place that's too dangerous, or, I did something to make someone want to hurt me, in which case such methods of security aren't sufficient.
I think it's critically important to take security seriously for businesses and governments, but when it comes to your own personal day to day life, there is a point where paranoia will spoil your happiness.

I'm certain that AMD is happy its cpus are invulnerable to Meltdown attacks. "Meltdown"--these names are so silly--it's like they think, "How can we name them in order to scare people?" It's like COVID-19--common flu strains are far, far worse in lethality and rates of infections every year--COVID-19 isn't a microscopic patch on the flu--but what do people worry about? "COVID-19"--sometimes I despair of the human race...

One thing that I don't see mentioned enough is the nature of actual exploit 'kits' in the wild. It is very rare to see monolithic exploits being used in an attack.
Instead 'kits' come packaged with many interconnected exploits all designed to breach a specific level of security culminating in a full compromise.
While an individual exploit might be tough to use on its own to accomplish much, every newly discovered exploit gives each phase of an attack additional methods to become successful.

Not so much compromises but certainly ego driven "Heh, no one is smart enough to figure out how to mess with this". There is also a huge issue with it being very difficult to account for all potential misuse circumstances. You are 1 billion % right about AI. The next generation of CPU development needs AI unleashed on it to determine what can be breached or misused for unintended access.
If chip makers all get together and make a commitment to a new way of creating processors we are going to end up with a very interesting delineation in technology history. We will end up with the "insecure era" and "more secure era" resulting in a nearly unfathomable amount of technology considered to be obsolete in the modern world no matter how well it performs. The e-waste problem that results from this is going to be disgusting.
Denial
No they aren't.
I also have no idea what this has to do with naming of attack schemes. No one I know calls the ongoing coronavirus, COVID-19 - it's only used in scientific publications or news releases, whereas meltdown is a name for the masses. So it's literally the opposite as far as my experience.

Intel Management Engine (ME) Firmware Version 12.0.49.1556 (S&H)(1.5Mo)
Is this the new patch that makes it slower? Because I did the mistake and installed it already. If that's the case, I'll re-install the slightly older one
Intel Management Engine (ME) Firmware Version 12.0.49.1534 (S&H)(1.5Mo)
I also use the InSpectre utility in order to disable the old ones that make the CPU slower in certain aspects.
I want my gaming PC with Intel CPU and all its holes open, but all the performance untouched. I never even use banking or Credit card on this PC. Nothing that worries me. Simply want the performance it was indented for.

You will never convince me that all these side-channel attacks have value for "professional" malware hackers. Why waste your time in trying to see valuable information in bits of cache memory when you can simply take remote "root" control on millions and millions of computers of uneducated users by sending them letters with fake links (and even software) promising something, or by putting "bad" versions of software to file servers (torrents)? And speaking about bank operations, as I take it most of the users use smartphones for that.
I guess, such researches are valuable for researchers themselves: they got reputation, they got grants, probably they even got Ph.D.

Well, one day people are going to realize having all these security holes patched makes the intel chips worse-off than the recent Ryzen 3xxx chips. So they will either (as some said above/before me) forgo the patches entirely or only take ones that don't hurt performance really bad, or they will patch them up and realize better safe than sorry.
I do content creation and DO use things such as various sites to buy models and graphic files. However, that being said, I have no regrets skipping the intel when it saved me a few hundred to go AMD and still have 95%~120% the performance in the tasks I do daily here.
For gamers though, I still think the intel will be performance king (maybe Ryzen 4xxx will take the crown, or maybe not), at-least until the games use more than 8 cores / 16 threads (some do, many don't). Hopefully they don't find too many bad holes on the AMD setups, will keep fingers crossed.
Didn't think I'd see much improvement in performance on many things coming from a 4.4ghz 4790k with 2400mhz memory - but it was entirely worth it to get an 8-core Ryzen 3xxx chip.
No regrets, and much less security holes (as of now!) to worry about taking performance away.

We have no evidences that they already added those attacks into their tools. And I do not believe in folks having interest in my PC (except for bot-net). Any crime should be prepared, and preparation has to be short and cheap enough.
I do not. I just do not agree with hype/panic.
Sure. But there is bigger danger than hackers - big data collected by commercial companies. I saw dramatic example of "data fell into wrong hands". At the start of XX Dutch government decided to collect extended data from population (like religion, ethnicity) to offer a better services. And all was good until Nazis occupied Netherlands, took all collected data and got all Jews by the list.
Only if it will not cost a usability. Take a flat/house as an example. Sure I do install lock (or two), but despite the understanding that professional housebreaker will open those locks I do not install several more locks (may be of different types), several more doors, several dogs, etc.
