it wouldn't be a week of hardware news and the recap there have without a lot of nvidia and AMD news and we have that for this week so nvidia has added samsung memory to its roster for video cards and the internet seems to be jumping to the conclusion that therefore all micron memory must be bad but that's not actually why nvidia added the memory to the roster of board components or to the Bill of Materials also anybody a driver fixes for most of the BS or DS we've been seen we have an update on days without our checks and games and AMD with their very many news announcements for GPUs and CPUs alike before that this video is brought to you by coursers vengeance RGB memory coursers vengeance RGB Ram uses pre-screened ICS for better overclocking Headroom and tighter timings of courses Ram also has the benefit of wide region motherboard support by landing on qualified vendor lists for motherboard makers and trained wide compatibility between boards learn more at the link in the description below first up Nvidia add-in Samsung memory to its build materials for its video cards for the RT X series this includes partners as well a lot of the board partners when they buy the reference PCB and/or the GPU from Nvidia they will also purchase the memory from Nvidia after Nvidia purchased it from their memory suppliers so Samsung memory is getting a lot of spread here and because of the artifacting issues that have been discussed online it's not actually widespread at this moment but because it appears to be widespread from the discussion online a lot of the conclusions drawn are that well if Samsung is being used now than micron must be bad in reality it is possible for of course some of the micron memory to have been bad maybe a bad batch or something where we haven't confirmed anything yet but the reality is this happens all the time it's adding another supplier so that demand can be met with supply of the video card so this is not abnormal it's every single GPU launch including with Vega even as the as the memory supply comes to fruition because it's a new type of memory to dr6 it's not readily available the additional suppliers will come the market and supply the video card makers with their memory so this is not it's a bit of jumping to conclusions a bit of misconception but it is possible for a bad batch of micron to have ended up on the card just as we said but also Samsung being added doesn't mean that literally all micron cards are bad just as some anecdotal evidence we have about 12 review sample 20 series cards and all of them I think have micron there might be one that Samsung but certainly almost all of our micron none of them have exhibited any issues whereas we have basically an equivalent amount of cards from you all on loan that are artifacting or experiencing other issues and those also have micron so some anecdotal evidence for you but not all of them are bad clearly either way though Samsung's being added doesn't necessarily mean anything we'll see sometimes the memory might be capable of higher speeds from one supplier versus another but they should all meet the baseline spec speed and it's primarily overclocking or that'll really matter also in Nvidia news is the driver update that fixes a lot of the pSATS and some multi-monitor issues so just before Nvidia's newest driver release we confirmed that BS ODS were largely occurring from things like using G sync displays using high refresh displays using high refresh displays with G sink especially and also multi monitor configurations for causing various issues so these have largely been fixed about 24 hours after our first video and Vidya had already been working on a driver at the point we posted the video of course they posted driver version for 16.8 1 which resolves several of the multi-monitor related issues including the following multi monitor idle power draw is very high that was one of the fixes blue screen crashes when exiting games while using both a G sync and non G sink monitor synchronously mouse cursor are causing FPS to go out of sync with window g-sync flickering in the witcher 3 and then not listed are multi various other BSOD issues including those involving high refresh displays we have seen some of the BS or the issues that we validated disappear with this patch so if you're still seeing them post your monitor model below and any information related into the blue screen of death that you might be experiencing or CT d's because this is a hard issue to validate as we said originally it is it's a bit spurious it seems to not be a hundred percent consistent when BSO DS will occur on the r-tx cards some people have reported that their Titan V's are showing similar issues so this is a driver level issue not a hardware level issue as far as we're aware so it should be resolved as driver updates keep going out and if you still have BSO DS after updating post information below about your system config and what's causing the blue-screen and then we'll send that along to Nvidia if they need any additional help on it so as far as other testing goes we'll have already at this point a live stream up so we're gonna be live-streaming some of our testing of the twenty series cards that were sent to us on the defective ones artifacting issues I will be working on things like memory down clocking power target changes may be some disassembly some thermal testing of memory stuff like that and before that stream we had already validated about 9fe cards with artifacting during the stream which will have already happened at this point we will have tested and memory frequencies power targets and done some disassembly of cards to find common threads potentially and of course I mean there's there's your future perfect tense with a mix of subjunctive mood for the weak next up days without r-tx and games 51 or thereabouts depending on this video goes up so we interrupt this program to update the ticker on days without r-tx in games and at 51 shadow of the Tomb Raider was supposed to have r-tx features when it launched or close to launch and it does not presently have those a battlefield 5 just shipped does not have our TX features and including the LSS for any of the games that are supposed to have those so still tech demo right now and this is largely because Nvidia and the game developers are still waiting on that big Windows patch which might come back out eventually after it's done deleting everyone's files if you didn't hear about that so once that patch comes out for Windows 10 the next big update we should maybe start seeing some r-tx enablement in games that's been a big hold up right now and a limitation for what can be turned on because nvidia does leverage some of the microsoft features coming out in that patch for their r-tx game SDK so so that's it for that one we're still waiting on games we're basically but next one seven nanometer Rome CPUs and Zen 2 is an AMD news item Andi has formally announced their second-generation epic line of currently named Rome Rome is based on a 7 nanometer process it follows the Naples launch of epic last year and it's also got Zen - micro architecture it offers up to 64 cores and 128 threads roughly targeting twice the performance per socket of previous epic CPUs in addition to a new architecture and manufacturing process Andy is deploying a new chip design approach with Rome and he calls this approach quote chicklets where by AMD uses multiple 7 nanometers n2 CPU dies all connected to a separate 14 nanometer IO die and these latest generation of infinity fabric will interconnect the chip let's and the i/o die as well as new memory controllers housed in the i/o die this new approach largely appears to make manufacturing simpler for AMD and importantly it's less costly in regards to chips and interfaces not everything scales equally with a process shrink reducing die size though required to make one monolithic die and instead making several smaller dies should mean better yields and lower cost the new epic CPUs it will be the first CPU is to adopt a PCIe 4.0 no present word on availability or public pricing but AMD is working on sampling select customers and markets just as a shoe-in here we're going to be seeing a lot more of this multi chip module approach to design going forward as monolithic wafers get difficult to make the bigger the die the more expensive it is to make the lower the yield which also increases the cost because you have more silicon that you're throwing away and more time you're spending on the fabrication line so M CMS will probably become a bit of a thing going forward including for Intel apparently and NVIDIA has also published white papers on its own thoughts on M CMS for GPUs in the future so 7 nanometer Vega GPUs get through some of the rest of the AMD news here for the week and they also announced the first 7 nanometer GPUs that it's working on and these are the form of Radeon instinct they are the MI 50 and mi 60 video cards of GPUs these are not going to be consumer targeted devices these are also enterprise cards they are used for things like deep learning machine learning and high compute work maybe some cloud computing in there as well the new Radeon instinct cards are based on TSM C's 7 nanometre FinFET process and AM these at Vega 20 architecture the mi 60 just as reference will only use or only support Linux so it is very much a a scientific grade or server grade card depending on what you want to do on it and like the new epic CPUs these new Radeon instinct cards will be the first to adopt the new PCIe 4.0 standard the mi 50 and mi 60 can also be interconnected via AMD's infinity fabric link allowing multiple GPUs in a single server the cards are slated to launch in November on November 18th and there's no word yet on pricing or availability we have seen some of those Vega GPUs appear as just the code names in some benchmarks but keep in mind that this is not meant to be used as a gaming device see sonic raising MSRP see sonic announced that effective December 1st 2018 all of their china built power supplies will see a price increase in US markets this follows along with some of the tariffs we've been talking about lately see sonic attributes these price increases - what they call quote recent market developments stopping short of saying the word tariff and the china-us tariff or has been setting the stage for some time now on price increases for computer components now one thing that does dodge these is is memory and SSDs if you look through the whole list that the the whole US tariffs list memories not on their SSDs not on there so that benefits us I guess in one way because they've been coming down in price a bit but other components things that can be considered DIY components for more core audience so you have cases video cards motherboards power supplies of course devices like that those are impacted and the china-us tariff changes will be affecting see sonic among the first in the official MSRP adjustment department so looking at the affected SKUs they have a list of them price increases range from ten to twenty dollars and many this won't be an insignificant amount especially at the low end it becomes sort of nonlinear the way it scales see sonic maintains that the solution is dynamic and will be adjusted accordingly so if the tariffs increased or decreased so too will the price hikes also announcing a new server CPU not to be outdone Intel has announced its newest line of cascade Lake Zeon's and the new cascade Lake Xeon ap or advanced performance as the initialism means these CPUs are based on mCP or multi-chip package designs following suit of epic and it offers up to forty eight cores 96 threads with support for 12 ddr4 memory channels big move there on the memory channel support and this is kind of interesting because we don't typically say like AMD did it's been a while since AMD has been in a market-leading position and to be first with a design that has now been adopted elsewhere by Intel here is it's critical for Andy's ongoing hopefully success as they try to challenge the CPU market segment and really what we need to see now is some challenging on the GPU market because any company holding as much market share as Intel and NVIDIA have in the past does lead to things like stricter policies with how media is approached for example stuff we do and work with so anyway the design excuse the monolithic die approach of the current Zeon's in favor of a multi chip approach multiple chips and dies on one package and cascade Lake will have in silicon mitigations respecter in meltdown this is important it's one of the first architectures that we'll have in silicon mitigations not just firmware and micro code updates and we currently are unsure of other specifications for the CPU so of course the new cascade Lake chips are based on Intel's 14 nanometer process as 10 nanometer isn't ready yet and it won't be probably until 2019 the 10 nanometer ice Lake Zeon's likely won't be here till 2020 following Intel's present roadmap and that leaves cascade lake as Intel's a stalwart defender in the server space against the am the epic CPUs although Intel's been doing still just fine in the server space and in the desktop space they have a lot of market share port smash and side-channel attacks being discussed lately so just as specter and meltdown are being cleaned up researchers have found another vulnerability called port smash port smash is a side channel attack that targets CPUs using SMT technology which is bay we all mainstream CPUs and that includes both Intel and AMD alongside others like arm but Intel cause there's hyper-threading AMD calls there's SMT it's kind of a brand name versus a generic name thing same idea though port smash requires malicious code to be running in parallel with a legitimate process on the same cpu core then through SMT or hyper threading the malicious code being executed on one thread can eavesdrop and leak bits of encrypted data from another thread allowing an attacker to receive the encrypted data and reconstructed the researchers who are based out of Finland and Cuba said they do not believe this exploit is unique to Intel in fact side-channel attacks aren't even unique to CPUs researchers at the University of California at Riverside have successfully exploited NVIDIA GPUs as well the side attacks and in the case of GPUs these attacks can be used to monitor web activity and steal passwords the researchers are currently delivering their findings to end video who will be rolling out a patch to address the side channel attacks and vulnerabilities researchers are also in contact with both AMD and Intel talking about their findings to see if their respective GPUs can be affected in a similar way to Nvidia's the research group now plans to test the side channel attacks with Android phones coming up next and we'll keep an eye on that story because that would be a certainly a big one since phones are largely perceived by users to be impenetrable for viruses and malware that's obviously not the case SK Hynix launches at 4 d at nand playing for DHS with the other manufacturers so SK Hynix announced its 96 layer 14 and it's called for D not because it exists in 4 dimensions like you would think it would mean it's because they use at CTF or charge trap flash with puck not that one it's periphery under cell SK Hynix uses this approach as compared to the 3d floating gate design and SK Hynix claims that this is a first and calls their new memory again for D and then following of course 3d NAND but there was never a brand name to team and I guess that would be planar SK Hynix is at new 14 and will allow chips to be 30% smaller that's the big thing here and that also allows them to increase density and yield considerably thereby supporting better prices SK Hynix plans to use 14 and to power one terabyte as is DS with in-house controller designs by the end of the year with enterprise designs it slated for 2019 short one here the Corsair Vengeance 50 180 gaming PC courses rolling out a new fully built gaming PC option something that doesn't excite a lot of our audience but worth keeping an eye on so Corsair is in a bit of a unique position when it comes to pre builds because they can provide most of the components in fact in this one course there's got 9 out of 13 of the components listed made for the Vengeance 51 80 it also uses IQ of course the proprietary interface software so venden 51 80 will have an i7 8700 9 K it will also be using a B 360 motherboard because it's an ankh a CPU I suppose an RT X xx 80 and an undisclosed 2 terabyte hard drive option also have a copy of Windows 10 of course so the 50 180 if you're curious will be sell sold for twenty four hundred dollars and is available now although I mean if you wanted to know how performs just any of those individual components for bench works and then also of course there is the hydro X series has been more fully detailed it's been T is several times my course R at this point has been pushed back launches have been delayed for this one but this is course there's open-loop water cooling solution following the acquisition of several top talent members from ek water blocks previously so Corsair T's the hydro X series at a gaming event in Paris and also had information suggesting a CES announcement for 2019 that'd be just a couple months from now the leaked images show a CPU block a GPU block and a reservoir and pump combination Corsair has been working on entering the custom water cooling market for some time after again acquisition of former ek talent there for a and do custom loops was only a matter of time of course there's been teasing hydro acts on their website including one video that was like just the letter X made out of water or something like that so pretty obvious with her eventually released and they also updated the teaser to show water blocks for the new Nvidia r-tx 20 series cards and since then there's been no mention of other products in the hydro ax lineup so we'll have to keep an eye out for CES to learn more that's it for this hardware news
