Calling me a moron because you don't agree with my opinion is pretty childish.
This is getting ridiculous and a lot of you need to grow up.

You also have an interesting idea on how hackers do things and seem to think they would need to keep using spectre or meltdown over and over again to get back in each time.

NAT is NOT any kind of firewall or device it is a technology that even your modem uses to give out IP addresses you can look that up at the link I posted if you're still confused.

Ports not being forwarded doesn't always protect one from anything either.
Hacking isn't as complicated as you would think it is. Hacking some clowns home network is a joke.

Just because I don't know a lot about Linux as most of you o nthe forum doesn't mean I am stupid and don't know stuff.

You don't have to agree with everyone but a little respect goes a long way.

I need to give some jerk repsect after they call me a moron for speaking my opinion???

That's not how things work where I come from.
Respect is earned not given for any reason without merit.

I have a few systems running Debian and FreeBSD.

Intel is more stable, especially for Windows systems.

Most topics here require fact, not opinion.

Yes, you are.

Am not :P

The fixes applied to the newer browser versions make timing-based attacks more difficult but it is still possible to create a high precision timer using the web worker feature of HTML5: https://www.bleepingcomputer.com/news/s ... -defeated/

And the vulnerabilities allow the attacker to read the memory space of the entire browser so if one tab was compromised then password details entered in another tab could be read, there would be no need to download or install anything in the target machine.

Kind of sounds like you aren't providing any evidence that these attacks are wide spread on every web site and everyone should panic.

I am not claiming the attacks are wide spread, nor am I suggesting anybody should panic. I'm just pointing out that the risks are real and that people should be applying all the available mitigations (and disabling javascript wherever possible) and that AMD is a better choice than Intel because they are less vulnerable to this class of exploit.

And there have been some attempted exploits discovered in the wild: https://mobile.twitter.com/avtestorg/st ... 2997861376

Anyway, here's a nice article on the subject that's worth reading: https://www.technologyreview.com/s/6129 ... n-attacks/

Performance wise, I'm curious. Intel has hardware video encoding built in, it really speeds up encoding. How well AMD encodes to H.265, for instance?

Thanks!

AMD Ryzen 3900X 12 cores 24 threads - benchmark 64 seconds (TDP 105 W)
Intel i7-9700K 8 cores 8 threads - benchmark 86 seconds (TDP 95 W)

Looking at this, one Intel core is more efficient than one AMD core. Yet, AMD outperforms Intel using relatively less electrical power. But AMD costs more, way more! Interesting.

Another thought. Since AMD needs roughly two times more threads to perform the same job it also needs more RAM. For instance, when compiling with -j4 one thread may consume up to 2 GB of RAM, thus at least 8 GB is required. With AMD to build with same speed you need -j8 which needs up to 16 GB of RAM ...
