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 6990 as well as two
GTX 580s 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 35 or 36°
depending on whether we can actually get the camera to focus for you guys or not
there we go so 30 let's say 35° on the
GPU cores and then we've also got our idle
power at the wall being about 96
Watts so what I'm going to do is I'm going to 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 the
these different solutions just so you guys know for the max power I using the
batch size test as recommended by Sky MTL from Hardware conu 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 at around 340 watt so we're
just going to record that as 340 and uh
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° on each of the gpus 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 or 79 rather um so we'll go
ahead and record that in our
little uh Power W there really is quite a dramatic difference
between the maximum power and the uh and
the minimum power NVIDIA's really done a good job of uh 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 mahz on the
GPU Focus there you go very nice very
cool all right so there's my idle power consumption for the Radeon 6990 so we'll
call that 132 and I should write that on my handy
little chart at some point and then um
oh hold on let's just do that and then
here are my idle temperatures so it settles in around
41° on the GPU that has less ventilation
so the one at the back of the card and 39° on the GPU at the front of the card
so there there's our idle values so here's the max power
consumption of the radon HD 6990 for the
sake of argument why don't we say around
400 varies let's take the Peaks almost
the peak so we'll say about 405 Watts
cuz it sort of Rises and dips so we're running the 3D Mark test and uh let's
have a look at what we achieved in terms of maximum temperatures
bringing up after burner here so our Max
temps Peak this is artificial um but
they peaked at around 85 and
82° on both of the gpus so here I'm just
going to make it focus focus focus thank you all right so 85 and 82° were my Peak
temperatures on the
gpus so let's call that a 15 50 wat
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 uh factor that in if you want to
figure out how much power they're actually consuming so this is two GTX
580s both of them are stock clocked reference designs and our idle
temperatures are actually come in similar on one of them okay so similar
on this one this is the bottom GPU at 34° 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 uh 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
uh going with the two dedicated dual gpus rather than a single dual GPU card
uh in both cases consumes more power it is
um the highest performing solution out of all of the ones that we've looked at
so that's to be considered as well although sometimes the margin is
substantial and other times it's less substantial uh no it's fairly
substantial for the most part just looking at uh at these numbers here
anyway so uh yeah I'll show you the load
temps it's me in my pink shirt so for
load temps we're looking at 82 and 77° so that GPU uh that is starving for air
in the middle uh really well does starve for air a little bit and I think that's
pretty much it guys so stay stay tuned and I'm going to show you all the audio
samples from these cards thanks for checking out this video don't forget to
