hey guys build Zoid here and today we're going to be doing a rundown of the various r-tx 20 atti PCBs well not really a rundown just kind of I'm gonna point out the ones that I think are worth considering so yeah because unfortunately the r-tx 20 atti PCBs they're very it's a lot of the same thing over and over again as far as I'm concerned which is why I've gotten really tired of looking at our TX 2080 TI's relatively quickly because it's just like the cards are like it's basically just the same thing with slight like layout differences there's not really anything all that new or interesting between any of the cards at least the cards that you can like regularly by this video is brought to you by us and the disappointment PC t-shirt a great way to support gamers Nexus and to commemorate a year of despair is to wear a constant reminder of your disappointment the GN disappointment t-shirt features release dates from major milestones like spectra and meltdown the cts labs report and RAM prices accompanied by an artifact of design that matches the infamous XD failure mode on new video cards the shirts are high-quality fabrics and prints and are available in soft 100% cotton for a comfortable fit or available in a popular try blend visit store gamers Nexus dotnet or click the link below to grab one now starting at $19.99 there is cards like the galaxy all of Fame card which was really really cool but unfortunately they made a hundred of those which that's the extreme overclocking version and they made only a hundred of those I'm not sure if there's like a cut-down consumer version there probably is but it's cut down so everything that made the extreme overclocking version cool isn't on the consumer version so it's just like oh well that's not you know that that's just boring as far as I'm concerned and yeah on the on the other like the other cards are just like the cards that are currently available because there are interesting cards coming out like there's gonna be a 20 atti kingpin Edition but ultimately I don't think that ones be a whole lot better on air cooling or water cooling than just your other light than any of the other cards is that ones really geared for extreme overclocking and then there's going to be a lightning from MSI but I'm not sure what exactly they plan to do with that historically a lightning should be great for extreme overclocking but considering how Nvidia has just been like just like Nvidia is just ruining extreme overclocking support I don't think MSI will be allowed to do quite as much with lightning as they would like to or if they like it might be really half-hearted because that's what I thought think what happened kind of with the 1080 t I like it was a lightning it just wasn't it didn't seem to be on the same level as some of the past lightnings that you know came before the the 10 series so yeah so those cards are like you know those are cards that exist but unfortunately you can't really buy them right now so we're just gonna look at cards that are available or at least PCBs that are available don't the full cards I don't know how the heatsinks perform you should probably ask Steve about that not me I just get sent pictures of PCBs so I can figure out what components are all in them and if said components are good or not so then starting off with the founders Edition PCB which is extremely common okay like this is one of those things like that's a founders Edition card and that uses the founders Edition PCB guess what this card uses you save a lot of money if you buy this thing right and I'm in the UK that's why this is in pounds so this is still a Founders Edition PCB this is also a Founders Edition PCB that's a Founders Edition that's also a Founders Edition also also also not sure I think this is probably a Founders Edition but with Asus I'm never quite sure because even for like low-end cards Asus for some reason makes custom PCBs I'm not sure I guess they have I guess they have more manufacturing capacity than they know what to do with fir for actual boards so they actually just manufacture their custom cards even for low-end even for their low-end GPUs so I'm not a hundred percent certain that this is a founders it it probably is but I'm not gonna say it definitely is because I don't know with 100% certainty next we have this thing which is a founders edition another founders edition ASIS card so I'm not sure this is almost certainly yes another founders edition and then we have another Asus card where I'm not sure now here we have the zotac amp extreme which is like the first custom card and the thing is it's like here's the problem with the r-tx 20 atti custom cards you basically all of them right excluding the MSI gaming X is you get 16 power stages running in either 8 or 10 phase mode and this applies even to the extreme overclocking cards though I'm not sure about the kingpin Edition I'm pretty sure and the Lightning though I think the Lightning is a 16 phase I've not managed to find like I'm pretty sure the Lightning's of 16 phase I mean 16 power stage card because none of them actually run doublers none of the phases are out of phase with each other so basically and that includes the founders Edition the founders Edition runs an 8 phase voltage controller in 8 phase mode and they basically have this weird asymmetrical phase setup which which works but and the reason why NVIDIA has gone for it with the the 13 like in videos reference card is 13 power stages and the whole point of doing that is that those 70 amp power stages hit peak efficiency for the kind of current and RT x 20 ATT I would put out while pull stock settings if you have 13 of them so basically the reference card is optimized for peak efficiency at stock settings and a little bit of overclocking like it's not it doesn't get significantly less efficient as you overclock but definitely some of the other cards out there have some advantages the further like start getting like getting bigger and bigger advantages the higher you push your core claw the higher you push your power consumption so yeah that's that's kind of that but ultimately everything's like their most of the cards are eight phase and the zotac card is no difference the main difference with the zotac card is that they have four phase memory power but that's just like it's not going to do it's like I'm nor I well I know exactly why ZOTAC did it so tak wants to be able to claim that they have the most phases out of any RT X 20 a DTI manufacturer out there which they technically do but that extra phase they tacked on is is on the memory it doesn't do anything so and and they don't have the most true phases because they still use the U P 9512 voltage controller which runs in a phase mode so yeah it's basically just like so that's an eight plus four phase that they have and they do run the 16 power stages and then for power stages for the memory power so you know it's ever so slightly better memory like it's slightly better v core vrm than the referent than the founders edition slightly better memory vrm than the founders edition but not to an extent that I would actually care right like it's not gonna make a difference in your data in overclocking on ambient it's probably not even gonna make a difference in overclocking on ln2 now then moving on to a card that is actually interesting as far as I'm concerned we have the ROG Strix and we're just gonna look at it on Asus is own website so the reason why I like the Strix and I was hoping for bigger pictures yeah okay that's great but uh the reason why I like the Strix PCV is very very simple so you get a bios which that which is in my opinion with an RT x 28 ET i that's like the most innovative feature on any of these cards because there's like two of them that i'm aware of that have bios switches and so that's the FTW three and the Strix now where the Strix differs from the a lot of the other cards is that the Strix actually chooses to intentionally use the MP 2888 voltage controller and the threes Anaya is that controller supports ten phases and it's running in 10 phase mode so this is one of the few like this and the Galax holo fame are the only cards I'm currently aware of that run ten phase that have the vrm as a ten phase for V core which is really really cool it still has 16 power stages bought Asus upgraded the power stages they're actually 70 M power stages from Texas Instruments not from Fairchild Semiconductor and these are CSD 95 for 8 zeros and there ever so they're well they're a bit more efficient than the FDM f31 70s that everybody else is using like literally everybody else is using the the Fairchild Semiconductor parts and so essentially asus has a slightly more efficient vrm they have slightly more phases than ever they have like two phases more than everybody else and also they have much more output capacitance than anybody else it is worth noting that I don't think that actually makes a difference like all of those advantages that Asus has in their vrm in day to day overclocking I don't think you'll notice if you were on liquid nitrogen you might but probably won't so yeah but ultimately because of all the little like it Asus like at least tried to do something to make the PCB a bit better and so I actually like because of that I like the 20 atti Strix PCB quite a lot because it has the like it's not a huge difference but it does have the best of erm and it has a bios switch and that's kind of the end of the story for why I like this PCB next there's of course the like a lot of people obviously want to know about the MSI card because hey it has a 6 pin everybody else only has 2 8 pins well the thing is MSI is on a 14 power stage setup 8 phase of erm so this is basically as close to the founders Edition as you can be in terms of your VR in terms of your DRM as possible without being a founders Edition like they've added one phase to the V Corps I mean not even one phase they added one power stage there's 14 power stages instead of 13 they still use a you p95 12 and yeah that's that's kinda the end of that for the vrm now where the big difference is between the the msi card and the founders Edition are is that MSI removed a whole bunch of current balancing circuitry and I assume that's because they have more power connectors so they're not as power can strike this basically like it's not an issue of the power connector not handling the power it's an issue of Nvidia's ridiculously strict software power limits they just won't let anybody make a card with an 800 watt power limit in the vials so if you don't want the card power throttling when you max out one your power connectors you need to have some power balancing circuitry but since MSI has more power connectors than everybody else they can cut back on the power balancing circuitry because it's less likely that you're gonna max out an 8 pin and another 8 pin and a 6 pin if you still stay within like the regular Nvidia power limits so that's kind of what they opted for there they also have fuses on the power connectors which I don't think do a whole lot because generally speak the the scenario where I could really expect those fuses to blow is if like one of your power stages shorted like shorted like die have failed closed where it shorts the 12 volts to the output of the vrm and the thing is I doubt that that fuse is gonna blow faster than the GPU core is gonna die when exposed to steadily rising voltage it really doesn't take a lot of voltage to quickly kill a you know like silicon like you you can basically just brush against like if the core voltage blips to say 2.5 volts for you know a microsecond that chip is dead and if the fuse doesn't blow up before that happens the chip is dead and so I don't think the fuses are all actually all that useful and if anything if you were trying to do extreme overclocking I think they'd get in the way because you might blow them up while just pushing regular amounts of power so yeah that that's kind of like that's basically why I don't really like this this card where it's just like like PCB wise I don't like it I don't know about the cooler the cooler might be great and if the cooler is great then a good reason to get it would be the cooler but as far as the PCB goes it's basically a founders Edition with an extra power connector oh and some fuses that might not do a whole lot if you actually like have a short circuit on the card so yeah but that is the gaming extra Oh next we have the EVGA FTW three which what do you get with an FTW three well you get a bios switch and you get the same 16 power stage eight phase-- vrm that you get on like say this gigabyte card right here so yeah basically everything I say VR my is about the FTW three is also true for the extreme card here as well as the extreme water force from gigabyte they do have a version of the 2080 TI which comes with a water block and that is just like it's 16 power stages runs an eight phase-- mode uses AUP 95 12 and what else is there oh yeah they're the one minor difference is that gigabyte uses much smaller power inductors than everybody else but I don't think that's actually gonna make a difference unless you're doing extreme overclocking and even there I'm not sure because I don't know the spec of the parts that gigabyte is using they're just suspiciously small not that that would be an issue on ambient cooling it's just like if you tried to push say 500 watts through the I mean 500 amps through the VRM they might be an issue might probably won't be but could be because everybody else is using larger parts and generally with inductors the the size of them kind of has a big role to play with how much current think they can handle well yeah so VR mo is the the FTW 3 basically takes the or the FTW threes vrm actually uses the same inductors as what you would find on the founders Edition and they basically tackle in three extra power stages still running ain't phase mode and they add a bios switch so basically if you're gonna be buying a card for sort of overclocking features I'd say FTW three or Strix whichever one is cheaper right if you just want the bios which just by whichever one's cheaper and if you want a card for like water cooling just buy the cheapest thing you can find that house the founders edition PCB and probably you might want to check with the manufacturer of said card if they're okay with you replacing the heatsink right so when you swap it over to the water block because some of them apparently aren't okay with that but yeah that is that is all the RT X xx atti PCBs there's really not that much to them I mean you know there's two different voltage controllers that you'll encounter across all the cards except like the Hall of Fame that want to have a special one but you can't buy that card as far as I'm aware so it's not relevant to the to the the discussion here and yeah Strix has the best like the RM out of the cards that you can buy FTW three is the next like the the other option to the Strix just because it has the bios which this doesn't like the extra six pin in my opinion here doesn't make any sense doesn't do a whole lot and if you want water cooling get a founders edition so yeah that is it for the video thank you for watching like share subscribe if you'd like to support gamers Nexus we have a patreon there's also store dog gamers and gamers Nexus dotnet where you can buy things like shirts mod mats mouse pads I think there was even some kind of goal like glasses as well so for drinking out of um so yeah you can find all of that and that obviously helps immensely with channel and other than that I have a channel called actually hardcore overclocking where I do other overclocking related content so if you'd like to check that out that would be awesome thank you for watching and goodbye
