so this video is going to be about the GTX 590 compared to its closest competition in terms of power and noise so that would be the sixty nine ninety as well as two GTX 580 s in sli so the first thing I'm going to do is I'm going to take an idle temperature as well as an idle power reading on the GTX 590 so the idle temperature right now is about thirty-five or thirty-six degrees depending on whether we can actually get the camera to focus for you guys or not there we go so thirty let's say thirty five degrees on the GPU cores and then we've also got our idle power at the wall being about ninety six watts so what I'm gonna do is I'm gonna put audio snippets at the end of the video so if you just want to see just if you just want to hear how these cards compare to each other in terms of noise then you can skip there otherwise I'll show you guys the temperatures and power consumption all along for all these different solutions just so you guys know for the max power I'm using the batch size test as recommended by Sky MTL from hardware connects I'm going to repeat that test so that'll give me a nice high GPU temperature as well as a maximum power load so here we go so our load power consumption for the GTX 590 clocks in got around 340 watts so we're just going to record that is 340 and you can see there's a cat investigating it and our maximum temperatures after running this particular little benchmark or rather our stable temperatures are 78 and 79 degrees on each of the GPU so we'll call that 79 and I really wish that window would go away I don't care I don't care 78 so there you go guys our 79 rather so we'll go ahead and record that you know our little power well there really is quite a dramatic difference between the maximum power and the and the minimum power in videos really done a good job of clocking down the GPU when it's not being used you can see right now it's actually stepping down right now so it goes all the way down to 51 megahertz on the GPU focus there you go very nice very cool all right so there's my idle power consumption for the Radeon 69 90 so we'll call that 132 and I should write that on my handy little chart at some point and then hold on let's just do that and then here are my idle temperature so it settles in around 41 degrees on the GPU that has less ventilation so the one at the back of the card and 39 degrees on the GPU at the front of the card so there's our idle values so here's the max power consumption of the Radeon HD 6990 for the sake of argument why don't we say around 400 berries let's take the peaks almost the peak so we'll say about 405 watts because it sort of rises in dips so we're running the 3dmark test and let's have a look at what we achieved in terms of maximum temperatures bringing up afterburner here so our max temps peak this is artificial but they peaked at around 85 and 82 degrees on both of the GPUs so here I'm just gonna make it focus focus focus thank you alright so 85 and 82 degrees where my peak temperatures on the GPS so let's call that a 150 watt idle total system power draw and bearing in mind that all of these numbers for the power are coming through an 80 plus silver power supply so you got to kind of factor that in if you want to figure out how much power they're actually consuming so this is to GTX 580 samples of them are stock clocked reference designs and are idle temperatures actually come in similar on one of them okay so similar on this one this is the bottom GPU at 34 degrees and then quite a bit higher so the reason that second one is quite a bit higher is that there's only that much space for the fan to draw air in whereas the GTX 590 is getting fresh air for both of the GPUs going out either side so let's get some load temps and load power consumption going on here and then we will have some commentary at about 465 watts the GTX 580 solution consumes the most power out of all of the configurations that are here so that's going with the two dedicated dual GPUs rather than a single dual GPU card in both cases consumes more power it is the highest performing solution out of all of the ones that we've looked at so to be considered as well although sometimes the margin is substantial and other times it's less substantial huh no it's fairly substantial for the most part just looking at at these numbers here anyway so yeah i'll show you the load temps it's me and my pink shirt so for low temps we're looking at 82 and 77 degrees so that GPU that is starving for air in the middle really well does star for air a little bit and I think that's pretty much it guys so stay tuned I'm going to show you all the audio samples from these cards thanks for checking out this video don't forget to subscribe to Linus tech tips you
