whoo that right there is the sound you make when you pick up an RX 574 25 Aussie dollars or in the US about 17 and a half USD making this easily one of the best deals I've got in the history of the channel now actually did get quite a few of these as well as this one right beside of the RX 470 which these were guaranteed working so there was a catch to getting these nitros or I think that the polls or something like that and that was that they're all untested and I didn't know if they worked though they said they'll working on the mining bench okay and so if that was good enough for the mining bench then they should be good enough for gaming after some tech yes loving but I got the right here the RX 4 70s I got these 460 Aussie dollars a pop and it got me thinking so that's about 42 USD as well it got me thinking with this right we've got the RX 470 where the RX 570 so I've got the two of these right together but what if you're in the flipping gaming PC's and also is it better say for longevity purposes to perhaps even load an Rx for seven TV BIOS on to an RX 570 and that's something I wanted to check because from the top of my memory I believe that these only lost about 10% performance to the RX 5 70s but at the same time the RX 5 seventies ended up using about 40% more power than the arch 4 70s did so that power efficiency is way in favor of the RX 4 70s and of course if you're putting together gaming pcs that means less heat in the case means you can get away with a more budget orientated power supply and not have to worry about potential problems in the future also on that note these only need a 6 pin these also only need a 6 pin but even though they've got an 8 pin you can sort of get away with Polaris by just using a 6 pin it was a weird sort of thing that I found out years ago and it's sort of stuck with these rx5 70s ever since but with that aside I'm going to get both the V boss is updated from the mining versions to the gaming versions I'm going to do a quick check before I apply some new thermal paste to check out the temperatures of both these cards give them some tech yes loving and then recheck the temperatures as well as after that loading up on our x4 70 BIOS on this sapphire our x5 70 then after that checking the power consumption and the performance because these right here the RX five 70s and the RX 4 seventies have a direct power meter where you can measure how much power the actual card is using regardless of what else is on the system so it's actually a handy feature of Polaris without aside let's just get this show on the road I give and you take it away it's clear that your fare and Sonia so both these cards have now had some tech yes loving applied to both the rx 570 this one here took a lot longer than usual underneath the fans there's sort of like some weird corrosion thing going on I guess that just happens when they've been mined on a little bit too long and I have seen this in the past with some other night rows that have come through here so maybe it's just a unique thing to these cards but I'm not too sure did take a long time to get off and so I had to give that a lot of extra tech yes loving and now it's looking pretty good hopefully the temperatures the before on this one was 66 degrees and the before on this one was 81 degrees so we're gonna put both of these on the test bench now see they often temperatures and then also load up an rx 470 bios on this to check out the performance differences and we'll just test across three titles because they are pretty much the exact same cards but once got a refresh bios and of course it's had time to mature a little bit more so technically it should be a little bit better but we'll find out how much better the rx 570 is right now so the temperature differences between these two Cod's was pretty interesting the Nitro only dropped down one degree and then the RX 470 the reference model here this dropped down six degrees so this got a bigger difference than the 570 and the FPS was actually pretty negligible I mean in Tomb Raider there was only a 2 FPS difference and then in Tom Clancy's the division to a 1 FPS difference and then in Far Cry New Dawn we got a 2 FPS difference but as we looked at before with the power consumption we had around 90 watts versus 120 watts so it looks like the RX 474 what it's worth is doing a better job in terms of efficiency but we're gonna try out one thing now and that is to put an Rx for 70 BIOS on the RX 570 and see what we can come up with and see how it performs so now trying to flash an RX 470 by us on to an RX 570 I know it seems a little bit bizarre made things even more bizarre when we successfully did flash the 470 nitro bias under the 570 nitro but then it was still coming up in Windows as an rx 570 and in fact the power consumption was like 6 Watts more than it originally was on the 570 so that was that just left me scratching my head maybe perhaps sapphire were using a more leaky GPU die on the nitro series which then overclocks higher generally but then for the RX 470 reference design they're using essentially the models that don't leak as much so they're more efficient up to a certain point and they don't overclock as well why is where things get even more crazy because we ended up getting the original rx 470 the BIOS from this reference model and it successfully flashed over to the 517 Nitro and this is where things got really really weird because it ended up showing up in Windows again as an RX 570 but the power consumption dropped down to around 85 watts so we saw like a 35 what drop in the power consumption but this time around the FPS was considerably lower than the 570 nitro original v bios in fact we were a lot lower than the iris 470 as well so important rater we had 51 average FPS 30 low and then pulling up Tom Clancy's the division 2 we saw a big drop down to 51 average FPS and then far cry new dawn that dropped down to 62 FPS so very weird results to the point where I guess out of these three sort of biases that I've used here today the RX 470 this original one does come out on top so basically if you are into maybe flippin pcs or you want to use your cards for a very long time then essentially the less wattage that part you is the longer it's going to lost all other things considered so there's gonna be less heat dumped in the case it's gonna be less heat being pushed out through all the components etc so but another thing worth mentioning as well as that trying to load up a custom BIOS now on AMD graphics cards like these the polaris cards are x4 70s and 570s doesn't work anymore at least from the top of my memory because as soon as you mod that v bios it then loses its signature and basically what you'll get is those error messages when you try to install the drivers or play games so you have to use the official v bios but within that v Bioscope you've only got a limited selection where you have to use for instance this bios on the RX 517 nitro and unfortunately just didn't really work out in this case where it was giving a lot law before that law wattage requirement so basically to summarize today's video when it comes to getting a GPUs with mining v biases on them and you're going to reflash them just stick to the original v bios and if you're going to have to tune it you might want to use maybe Whatman or msi afterburner with these cards and tinker around with a software mod because at least that way your games are going to work things are gonna work properly as opposed to loading up a different v by us which in this case this RX 470 was more efficient it wasn't when we loaded it up on to the nitro it just gave out a lot less performance than one would otherwise be used to and obviously I don't want to put that in a piece in and try and reef lip that it's just not good for the end-user to be getting a lot lower performance and also coming out of today's video the RX 470 did perform very well perform better in my opinion especially in terms of efficiency than the rx 570 so that was awesome to see but it does still leave the question open of was perhaps the RX 470 a better bin in terms of the GPU die than the rx 570 was was maybe the RX 570 the worst of the worst when it came to bending polaris cards that i'm not sure of if you guys out there know the answers be sure to drop a comment in the comment section below and also let us know what you think of the RX 470 versus the 570 which one would you pick over the other and wide
