HW News – AMD Zen Vulnerability, No More Blower, & Human Malware vs. PC Industry

by birtanpublished on October 2, 2020

Everyone welcome back to another hardware news recap for the week we're in Taiwan where we venture outside to film things that's always a nice change of pace so some updates on the hardware industry calling in sick for the last couple or

Well the last week or so and the getting its own side channel vulnerabilities to follow suits in the newest trend set by Intel over the last couple of years and video moving to some new TSMC process and we'll also be talking about dual

Axial coolers for AMD rdna two GPUs and ISPs proving their benevolence by removing the data caps because they definitely needed them there in the first place before that this video is brought to you by Thermaltake stuff ram

RGB memory available from 3,000 megahertz up to 40 400 megahertz an 8 gigabyte by two configurations the Thermaltake tough ram uses 10 addressable RGB leds for bright illumination and comes in both black and

White kits of memory learn more at the link in the description below over the past week or so of hardware factory tours we've learned a couple of things about the human malware situation unfortunately you're gonna have to bear

With me using that phrasing but one of the main things is that a couple of the companies have enacted policies mostly in the u.s. relating to how workers come to work so some of the hardware companies including Intel Dell and AMD

Are now as the biggest ones are now recommending that their employees telecommute or just call in for phone for meetings via phone conference the ones that still have people working on site a lot of the companies and switch

To a/b work days that's a couple places here in Taiwan are doing that as well but it's a lot less prevalent Taiwan seems to have things pretty under control and there's only a couple companies that have had any impact from

The human malware situation on at least our end of the visit but for what's going on the US a B workdays are set up where people are now alternating to keep the office about half empty some of the other companies that we work with or

That you buy from in the industry including case and cooler companies are struggling with the fairness of what they're doing so a couple the ones we've worked with here have decided that at home in the u.s. they're going to have

Their employees work from home and call in but then the warehouse work still need to go to the warehouse and ship stuff so that's been a sticking point for a lot of them the u.s. seems to be most heavily impacted right now in

Terms of hardware computer hardware companies changing their working schedules obviously in parts of Europe assuredly the warehouse schedules have been shuffled as for locally here in Taiwan the situation that we can tell

You from firsthand experience is that for the most part things are operating normally there's a couple places like EVGA where they've mostly shut their doors to everybody including their delivery people and then most of the

Other factories they vary from its nothing's changed to any foreign visitors need to wear a mask and that's about as far as it gets for the most part so even J's shut its doors we spoke with

EVGA CEO and with their PRF and they currently have restricted access to only one door in the building to get in and out they take employ temperatures multiple times per day they're requiring masks at the company

And they've also banned entry of all visitors including the delivery agents the longer-term impact to the industry is that the sign and design and manufacturing will slow down obviously over the next couple of weeks and it

Looks like Computex is questionable for happening at this point so we'll see if that happens most likely it'll get pushed back kind of like what happened a long time ago during the other human malware pandemic I'm sure I can't say

That one on you to be there so during our factory tours we've learned that the raw materials factories are seeing the highest order volume in Taiwan versus the other factories here because they're the ones making the

Supply and the companies can't get it from the sources in China anymore so they're getting it locally instead next news item is AMD's side-channel vulnerabilities so researchers with the grass university of technology released

A pretty big white paper detailing two new side-channel attacks known collectively as take away attacks specifically the two attacks are collide and probe and load and reload those are two separate groups of attacks both

Attacks are similar in nature as they both prey on the l1d cache way predictor and and these CPUs dating as far back as 2011 and according to the white paper every AMD CPU from 2011 to 2019 as affected so

That would mean Andie's most recent Zen – based CPUs are included in that list while we've been conditioned at this point to see new vulnerabilities from intel on basically a weekly basis it's more notable when we see something with

AMD that's not to say Andy has completely avoided vulnerabilities they did have issues with Specter for example although not all of the variants inspector but not nearly to the extent that Intel has suffered has AMD suffered

These new attacks appear to be Spectre based in nature according to the paper that may be why AMD stated it didn't believe the attacks to be new and that existing mitigations were sufficient the researchers refute Andy's claim and

Contest the status of the vulnerabilities and there's additional research from Tom's Hardware on this if you want to read up on it it'll be in our show notes at any rate according to the paper it says quote with collide and

Probe an attacker can monitor a victim's memory accesses without knowledge of physical addresses or shared memory when time sharing a logical core with a load and reload we exploit the way predictor to obtain highly accurate memory access

Traces of victims on the same physical core while load and reload relies on shared memory it does not invalidate the cache line allowing stealthier attacks that do not include any last level cache evictions end quote on that so as with

Other side channel attacks a potential attacker can fish out sensitive and protected data and even aes encryption keys from areas of a CPU that are not normally accessible while Andy hasn't indicated that there is or that there

Will be a specific mitigation for this apparently new attack despite what AMD says and these security advisory on its website recommends a couple of pretty obvious things one keep your operating system up-to-date by operating at the

Latest version of the platform software and firmware which include existing mitigations for speculation based vulnerabilities of course this says nothing of other software on the system like all the RGB software which is also

Riddled with vulnerabilities but the OS I guess is one thing following secure coding methodologies was a recommendation rather wide net implementing the latest patch two versions of critical libraries including

Those susceptible to side-channel as hack and then finally utilizing safe computer practices and running antivirus software probably not including Norton so we'll keep an eye on this one as it develops

AMD is obviously not invulnerable to attacks of its own it's just that the CPUs haven't been out quite as long so they'll take a while to figure out what happens and how the Xen architecture responds to different attempts at

Exploitation but for now this is the one to keep an eye on and video reportedly using TSM sees costs we'll call it in a new report coming from digital times this suggests that Nvidia is on the short list of customers who could be

Using TSM sees a chip on wafer on substrate or CW OS or Co w OS and this is packaging for upcoming GPUs TSM sees COAS is a 2.5 D packaging technology that packages multiple dies together at the wafer level on an inner poser

Something that TSMC calls quote wafer integration TSM sees process has evolved to be able to target chips that far exceed the radical limit up to 2x the radical limit TSMC and Broadcom recently Illustrated this with the first 2x

Radical limit interposer that will end up being used by Broadcom and HPC deployment the TSMC does this by essentially stitching interposers together at the wafer level and interconnecting them the benefits of

This approach are improved interconnect performance and bandwidth improves transistor density and higher memory capacity TSM sees current generation of Co wo s currently supports up to six stacks of HB m for its memory solution

As for what end video would be targeting with TSM C is a current solution is unknown however it's worth noting that Nvidia has used TSMC COAS packaging before on Pascal and on Volta based professional solutions

It's likely that end video would be leveraging tsmc technology again for upcoming titan tesla or potentially Quadro products that presumably based on ampere but we'll see AMD shifting to dual axial coolers for

Our DNA 2 GP is this at the time of filming our last news episode it had shortly come out right for that so it's a bit old now it's about a week old news but still we're talking on after and these Financial

Analysts day users on reddit sifted through the slide deck for the presentation and noticed a picture on a slide that depicted a radeon GPU sans the blower style cooler after a bit of speculation via the links reddit thread

In our show notes document scott herkiman the vice president and general manager of Radeon and also the guy who said that you were all jebaited even though that definitely was not planned commented to confirm the suspicions that

There will be no blower coolers with our DNA two GPUs this is particularly amusing to us because her comment is also the one who posted publicly and seems extremely confused as to why we and every other

Media outlet worth anything so that the blower coolers were garbage he seemed at the time about a year ago now to insist that they were just fine but either way I guess we just didn't get it and Andy is only now changing it so

Quote there will be no blower reference fans for gamers on next-gen so you're a corrector Gelman's said in the comments her comment expanded on this comment a bit further by saying that quote our AI bees may choose to do a blower design on

Any of the next-gen GPUs however the majority of feedback we received from the community at launch of the 5700 XT on AMD reference designs has guided us towards a duel and triaxial designs he says I'm excited for you all to see

Them when the time is right just like he was excited to say that we were all wrong when we didn't like it the first time most would agree that it's past time for AMD to ditch the blower coolers for its reference designs this is a move

That NVIDIA made across the stack for the 20 series although it made sparingly for cards in the past before that while blower style coolers have a place in specific setups it's generally better to just let the board partners make the

Cheap models of the cards with blowers for people who specifically want them rather than making it the blanket baseline design they've never been particularly effective especially in recent years with Vega and Navi with the

Power consumption going up intel is still sore about that antitrust lawsuit from a long time ago it's apparently not done fighting a fine that was delivered about ten years ago when the European Commission laid a 1

Two billion US dollar fine at Intel's feet for what was deemed to be illegal behavior for anti-competitive practices according to Intel the Commission quote got it wrong I'll remember that legal argument in case I ever need it quote

The Commission either took a wrong approach in its decision or it carried out and as efficient competitor aec test and it got it wrong says Daniel beard from Intel's legal department the fight stems from

Practices Intel engaged in back in 2009 by offering Steve rebates to OEMs for buying Intel chips so this in itself is not too uncommon the rebate side of things anyway Andy also does this there's something called

Marketing Development Fund or MDF that most of the companies pass around it's basically money in exchange for doing something normally not illegal so the Andy for example in the past has offered MDF for s eyes or system integrators to

Include its GPUs and systems that were built the key difference where Intel really to use its own words got it wrong is that Intel also offered money to prevent the S eyes of OEMs from using the competing CPUs so Intel previously

Was found to have paid the OEMs to exclusively use Intel chips this is the practice that was deemed illegal as an attempt to shut Andy out of the x86 market and that's the key difference MDF is pretty normal all the companies do it

To some extent whether or not it's a good thing is suspect but that's the way the industry works pain to not use a competitor that's where the problems legally start to emerge Intel paid what was at the time a record fine for its

Actions Intel contested that fine ever since filing an appeal that was rejected in 2014 in 2017 however the EU Court of Justice agreed to rehear the case according to reports though a decision is likely to come next year so we'll see

What happens ISPs suspend data caps proving that they never really did have a congestion problem as many are preparing work and study from home due to the violent human side channel attacks ISP is in a rare just

Of charitable 'ti or a cheap play for good press are suspending broadband data caps AT&T confirmed to motherboard that it was suspending all data usage caps until further notice these don't apply to everyone and where we live anyway

They don't apply to us but if you're not familiar with it the basics are that some of the ISPs do actually have a data limitation typically per month that you can't exceed or they'll either throttle you or charge you enough to remortgage

Your house likewise Comcast and t-mobile have announced similar efforts here Comcast stated it would not charge any overage fees while t-mobile has temporarily removed all usage caps Verizon asserts

That it doesn't place any usage fees on its broadband services and is instead bumping its speeds from 100 megabits per second to 200 megabits per second for some plans some ISPs are temporarily suspending late fees and disconnection

Fees in addition to these changes so surely ISPs are remaining vigilant and avoiding Verizon's colossal PR dumpster fire of firefighters getting throttled when they were trying to combat rampant wildfires the fact that

The ISPs can at will if the data caps and increase the speeds that shows how arbitrary these restrictions are though these policies in the first place are obviously here to make money and not because that there's some traffic

Limitation on a fiber-optic cable on which light is transmitted one way and then the other so ISP is would have customers believe that data usage calves help manage traffic congestion but these practices exist purely as a very thinly

Veiled cash grab on captive customers who in most cases can't get another option they don't have competitive options on the market but don't take our word for it in the coming months as hordes of users work study and play from

Home in an attempt to increase the chance of us getting D monetized from talking about human malware we can see how many ISP is speak up and so their networks couldn't handle the surge in traffic let's see how many congestion

And overage problems these data caps would really saved us from finally folding at home and Nvidia are calling for help with human malware related projects that users can donate CPU and GPU

Sources to folding at homes basically a software you can run on your system to use idle time to spin up your GP or CPU to process folding proteins according to the folding at-home blog all the projects are GPU accelerated thanks to

Open mmm the jobs that users can help fold our we can't well we can't name a lot of them thanks to youtube but the numbers are 11 741 which is apparently a receptor binding domain and complex with human receptor a ce2 there's eleven

Seven four six which is another one for AC e2 eleven seven for two which says it's a protease in complex with an inhibitor i don't know what any of this stuff means 11743 says that it's a protease potential drug target eleven

Seven four four says that it's a receptor binding domain trapped by a human malware s 230 antibody and then finally there's one eleven seven four five if you want to know those specific numbers that's what they are which says

It's a receptor binding domain mutated to the human malware causing virus trapped by a previous human malware from about a decade ago antibody anyway pcmasterrace and a hardware contributing they've set up teams they're encouraging

Users to join this is something that I potentially could see some fun getting into as well if only as an excuse to do some Alan T overclocking on a stream and see how quickly we can blow past the points that were created by some of our

Competitors by putting something like a thirty nine ninety x or Tesla's under Alan to so we might get involved but we have to go home for us to do that otherwise we could maybe borrow hi cookies lab and we'll have footage from

That coming up soon so subscribe for more as always you get a store documents excess net to helps out directly or patreon.com slash gamers Nexus thanks for watching things have been pretty good here so you don't need to worry

I've had us but going back home we'll see we'll see how it goes it does sound like the hardware industry is mostly called in sick in the u.s. though for the next couple of weeks everyone's telecommuting that's it for this one

Thanks for watching we'll see you all next time
