remember all the times you told your friend with a ryzen 5 pffft... well get your hat ready for eating perhaps... as apparently doesn't affect AMD CPUs

blah blah blah hardware bug in the processors ... probably only fixable via software patches ..resulting in some significant performance hits with Intel based rigs..

I'm pretty sure they make the new guys at the NSA just monitor your activities all day long... it is a form of hazing I guess.

Edit: ARM was found to be susceptible to Spectre. It has not (yet) been found to be susceptible to Meltdown.

It looks like someone found the same flaw in ARM v8 too ... That's 64-bit ARM.
It is unknown whether Apple's i-devices have it, because they supposedly design their own cores.

RIP drive speeds. At least video encoding and gaming seems unaffected.

Edit: looks like Findecanor edited out their summary. THE NSA GOT 'IM EARLY BOYS!

Nah. My writeup was too speculative.

Afaik they patched it for AMD also even if it didn´t affect them, so slower speeds for both CPUs I guess

YOU WOULDN'T BE HAVING THOSE HARDWARE PROBLEMS IF YOU JUST STUCK WITH THE PENTIUM PROCESSORS FROM 1995. THEY WERE JUST FINE!

Findecanor · « **Reply #9 on:** Wed, 03 January 2018, 09:10:49 »

Of course the Pentiums of the '90s would have been fine, if it weren't for the What Intel Giveth, Microsoft Taketh Away.
Although... these days we have CPU's faster than Pentiums in tiny form factors and fanless and that is not so bad.

Anyway... x86 is a horrid architecture. I'd prefer ARM7TDMI, MIPS R10000, Alpha EV5, UltraSPARC or even Motorola 68060 instead.

Intel did admit that there were vulnerabilities in ME. Late November last year, BIOS makers issued updates with ME fixes and Intel released a tool for checking if the system is patched:

atarione · « **Reply #13 on:** Wed, 03 January 2018, 11:54:51 »

I wouldn't claim to totally understand what is going on...

but so far it sounds like truly fixing the issue on intel part is basically going to take a redesign of their processors.... soooooo... yeah....

and annoyingly at least for linux so far they are rolling the patch out to all x86 systems including AMD systems despite AMD apparently not being vulnerable..

however becasue of Linux being Linux it is easy~ish to disable the fix for AMD based systems (or intel if you are outta your mind

)

tp4tissue · « **Reply #14 on:** Wed, 03 January 2018, 12:21:42 »

Intel loves this.. because now everyone gets to buy new CPUs .. hahahahaha

Also, people are like, no they're going to sue intel..

Yea they will.. but who has the most lawyers..

All CPU are vulnerable? I mean there's no currently top notch CPU which isn't vulnerable? What should people buy, except AMD?

I'm looking for a way to return my unreturnable CPU.

Just because they fixed a known vulnerability doesn't mean they are in the right. ME gives remote access above root and it is not possible to disable, this is fundamentally bad.

Speaking of vulnerabilities...This is old news but maybe we will see this technology rehashed in future silicon. In the future some script kiddie will take over my washer, dryer, toaster and couch. This technology will only become more pervasive. Imagine a future where these microchips will be very miniaturized, integrated with a full stack of capabilities, low power, wirelessly powered and absolutely everywhere, including everyday folks donning technologies similar to Google Glass, miniature robots inspired by insects and even nanobots.

Coincidentally, I found this, originally from a reddit thread:

Quote

As someone who worked in an Intel Validation group for SOCs until mid-2014 or so I can tell you, yes, you will see more CPU bugs from Intel than you have in the past from the post-FDIV-bug era until recently.

Why?

Let me set the scene: It’s late in 2013. Intel is frantic about losing the mobile CPU wars to ARM. Meetings with all the validation groups. Head honcho in charge of Validation says something to the effect of: “We need to move faster. Validation at Intel is taking much longer than it does for our competition. We need to do whatever we can to reduce those times… we can’t live forever in the shadow of the early 90’s FDIV bug, we need to move on. Our competition is moving much faster than we are” - I’m paraphrasing. Many of the engineers in the room could remember the FDIV bug and the ensuing problems caused for Intel 20 years prior. Many of us were aghast that someone highly placed would suggest we needed to cut corners in validation - that wasn’t explicitly said, of course, but that was the implicit message. That meeting there in late 2013 signalled a sea change at Intel to many of us who were there. And it didn’t seem like it was going to be a good kind of sea change. Some of us chose to get out while the getting was good. As someone who worked in an Intel Validation group for SOCs until mid-2014 or so I can tell you, yes, you will see more CPU bugs from Intel than you have in the past from the post-FDIV-bug era until recently.

right.... I'm thinking many people with a gen or two back processors are never going to get bios updates and will thus be vulnerable to Spectre until they replace their hardware..

I have been using a i7-4770K w/ a gigabyte Z87 motherboard that is 4+ years old at this point.. I'm quite dubious that if a bios update is actually needed this board will ever see it.. Some people claim that the fix may be a microcode patch that could be applied via the OS... but

? I'm not sure wtf is actually going on with this at this point.

The current crop of VR net-streaming videos, pr0n or otherwise, are not very high bitrate..

Even a 1050 (non-ti) could run them.

In the future, VR really needs 8k resolution and higher, because right now the image is too blockly still.

That will require at least a 1070..
