WTF I AM PANIC

>hyper-threading doubles performance
The absolute state of this board

debian still not update the fucking microcode

are intel putting in those flaws on purpose to allow government agencies to spy on random people?

or is it just incompetence?

>hyper-threading doubles performance
for certain tasks. I would assume docker and similar server software will pay a penalty...

>Buy used xeon
>Same performance post spectre and meltdown patches as a Ryzen 2600 for 1/3rd the price
>Hyperthreading increase performance anywhere from 0% to 100% depending upon application
>Average is 20%
>Now have 0.8 of a ryzen 2600 for 0.33 the price
Still a good deal

At this point I'm using Raspberry Pis for mail, file, and web servers. They're slow but work alright for my uses. Just bought a new AMD ThinkPad A series. It's pretty nice. I also use PowerBooks with Debian. I'm torn between a Ryzen and a POWER9 workstation. I have $2500 allocated to either one.

I ditched my Intel laptop and workstation last year because I'm not retarded and knew it wouldn't be over soon.

Probably both. If you want to be safe you should get a SISD (single instruction, single data) processor. They're slow but not unusably so. A Raspberry Pi 3 is fast enough for basic web browsing and office tasks if you install a lightweight Linux or BSD distro and window manager

>30% performance loss for Spectre mitigation’s pushed out so far
>another 40% performance loss for this vuln on top of that
Intel CPUs are running approximately 28% as fast as they were two years ago, this is assuming you are running all the patches and turned off hyperthreading.

Literally more than two thirds performance penalty. Suddenly my Thinkpad X23 looks competitive again.

and the power consumption over the lifespan of the build?

People mocked me when I bought my fx eight years ago, who’s laughing now.

Ok, so there is no clear explanation yet, is this an actual "you are seriously fucked, they can hack you remotely", or it's another exploit that requires physical and admin access to the machine to be performed, which at that point you have way bigger things to worry about than cpu vulnerabilities?

they just want you to buy new chips, that's all

12-30 watts difference?

Feels good being a Threadripper owner.

Just delid + delap and everything will be fine goy

it's another speculative computing exploit. If they can see your kernel space, they can get whatever is in there. The fix wipes the buffer whenever its done with the data, with a penalty of 3-9% based on model, according to techcrunch. Yep, that's on top of your Spectre/Meltdown penalty.

I wish people actually knew how to read here.

That doesn't answer the question you fucking retard

The new chips has the same issues plus all the non-disclosed issues.

>tfw still on kernel 4.19
literally 30 years behind
thx AMD

forgot to include that hyper-threading buffer data is also up for grabs and is recommended to be disabled in coordination with the fix. Enjoy losing your extra threads.
of course, but you need a payload to do that for you and send it back. it's like you can't think for your self, damn.

that's not how it works, iTODDLER.

Wow, “only” 40%, that’s a whole lot better than 50%. I guess Intel in the datacenter still makes a lot of sense, what with “only” a 40% slowdown.

I really don't want to be the devil's advocate, but apple is moving to their own inhouse cpu's, I'd expect them to say that and give their customerbase the impression they must switch.

Intel Pajeet detected, the performance gains from utilizing hyperthreading are well studied and “about 40%” is accurate.

You should be ashamed of yourself.

Intel is using AMD64, Intel has to pay AMD royalties.

>tfw the only intel cpu I own is in a thinkpad from 2006
Feels good.
By the way, does anybody know how this patch behaves on unaffected CPUs? I certainly hope I won't get a performance penalty on AMD, just because intel was greedy.

It is when you decrease by it. It's a third when add it. And you(?) decreased by it, meaning going from the remaining 50% back to 100% (by enabling ht) would be doubling the performance. Mathlet.

bad news for the 5 people who can afford intel quality processors and a good OS, yet still choses to use linux.

So this is where the tech industry is at.
Years spent building up a false sense of security and performance, with trash firmware on top of trash hardware, along with rising performance cost of running simple programs and websites.
now the quick fixes implemented years ago are catching up to INCEL processors and things will be slower than theyve ever been.
imagine if people actually started caring about optimization again because of this.
I doubt it, though.

oh no user

fucking idiot, those vulnerabilities are on every OS.

You should be able to just add a kernel parameter to disable the patch if it behaves negatively on unaffected CPUs.

Heh

if you dont think 99% of this shit is just a bubble predicated on marking trends and funneling capital into 'tech startups' even though those tech startups are almost entirely predatory venture capitalists trying to make a quick buck

Debian doesn't upgrade the microcode all they do is upload Intel's patches to their repos.
