hey Ron we're gonna tear apart a sapphire rx 460 nitro we did this third Platinum Edition card showed that it wasn't a great design but this one's much different so instead of using the reference our X 480 cooler this one has its own custom cooler from their nitro series it's a dual push fan setup and the fans are actually removable which we show on the review of the card for warranty reasons but we're gonna take it apart a quick overview of the card there's basically just a totally useless piece of the PCB here that has served only for aesthetic purposes so it's got their nitro with that I don't really know what way that's supposed to be oriented with the Cobra GI Joe logo on it then there's a couple LEDs on here they do not diffuse across the service put some LEDs a six pin and a cooler so we're just where you take it apart - it looks like I don't think I'm gonna do a hybrid model on this one I know some people have requested it but we've got some travel coming up so there may not be time for something quite like that but we will we'll see that really isn't a demand for a hybrid mode on this card because it already is performing within a decent spec the thermals are are fairly flat not impressive but not bad so the shroud is this these are not holes I don't know how I look camera picks it up those are not holes it's just a design shroud fan two screws holding the fan into place actually we can show this this is kind of neat so this is cool because it's fairly well designed instead of doing kind of a fan cable like like this thing here obviously a normal fan cable I connects to the board that's a four pin or you can even see these in here these kind of four pin cables which do actually power the fans the fans themselves are connected with the set of contacts and so when the when you remove it for warranty you don't have to mess with any cables which reduces the risk of someone who might not know what they're doing damaging or not plugging in the fans or whatever when they're done it's pretty obvious the way it goes together pins contact contacts and that's all there is to it so we've got the fan and then the shroud is very simply one cable here connecting to the card that controls both fans you can see that the cable splits to two others and there's talk to the fans directly on this is a little piece of foam this is not a thermal thing this is almost definitely a sound absorption thing or well not really absorption as much as just damping so there's no vibration so that'll stop any unreasonable vibration from the the fans against the aluminum heatsink causing any issues the heatsink very standard set up so it's an aluminum heatsink you can see just widely spaced aluminum fins there is there are two heat pipes so you can see the start at the end of the heat pipe here starting the end of the heat pipe here I crimped at the top as always and those contact those go through the aluminum heatsink then there's a giant block of what looks like maybe nickel plated copper right here and we'll see that when we pull it apart and that is covering minimally the GPU but it looks like it's also covering the vram so let's pull that apart okay very easy so here's what we've got this is a four gigabyte card unlike the 470 where we saw eight 512 megabyte chips or four gigabit this one has four chips 4 V Ram modules these are cheap thermal adhesive of bits you can see right here is the one for the other module that's missing super tiny copper block and that's because if you look at the GPU proper this is the smallest one we've looked at yet so this is Polaris 11 let's let's clean this off and see what it looks like all right very tiny piece of silicon there in the middle and then the substrate normal capacitors lining it on the outside so as usual just shrunken and Polaris 11 is a low-power little performance chip this is a two point something terrible option two points you somewhere around there I was interesting to you I didn't even notice this as a cost-saving measure sapphire hasn't even populated all of the pins on the PCIe which I did not notice before taking it apart even though obviously this is shown i realistically this things on a high performance card anyway so it's not going to be a 1080 doesn't use all the bandwidth of x16 so a 460 certainly won't but still half these pins are normally ground basically so they've cut those out so that's a cost-saving measure so if the vrm we've got a one two three four looks like five phase setup and or a four plus 1/4 plus one so you've got a four plus one phase design power design these are the inductors your capacitor bank and then this piece of metal right here is covering the MOSFETs I remove that oh there okay so another thermal sticky tape covering the MOSFETs so there's our MOSFETs pastured capacitor inductor chokes whatever you want to call it and that's our vrm setup the six pin power over here on the right side of the board rather than the top 4 v RL or v ram chips or modules rather so that's really it there's not a lot to this board for LEDs right here you can see there's a blank fan header up here that they haven't filled because why would they they have one fan header feeding into it that's powering both fans so there's really no reason to put another one there because they're not talking to the board with the fans directly anyway it's all done through a pass through travel pastures the chip that's it so that is an RX 460 as I said don't expect the hybrid model this but hopefully some other cool hybrid mods come in to him that makes a bit more sense with regard to thermals no for clocking and something like this card as always you can check our full review of the RX 4 60's are already on the channel should be
