1
00:00:00,280 --> 00:00:09,920
so this video is going to be about the GTX 590 compared to its closest

2
00:00:05,600 --> 00:00:13,280
competition in terms of power and noise

3
00:00:09,920 --> 00:00:16,720
so that would be the 6990 as well as two

4
00:00:13,280 --> 00:00:18,439
GTX 580s in SLI so the first thing I'm

5
00:00:16,720 --> 00:00:24,320
going to do is I'm going to take an idle temperature as well as an idle power

6
00:00:20,880 --> 00:00:28,760
reading on the GTX 590 so the idle

7
00:00:24,320 --> 00:00:30,240
temperature right now is about 35 or 36°

8
00:00:28,760 --> 00:00:36,120
depending on whether we can actually get the camera to focus for you guys or not

9
00:00:32,040 --> 00:00:37,360
there we go so 30 let's say 35° on the

10
00:00:36,120 --> 00:00:45,480
GPU cores and then we've also got our idle

11
00:00:40,440 --> 00:00:47,520
power at the wall being about 96

12
00:00:45,480 --> 00:00:50,840
Watts so what I'm going to do is I'm going to put audio Snippets at the end

13
00:00:49,160 --> 00:00:54,280
of the video so if you just want to see just if you just want to hear how these

14
00:00:52,680 --> 00:00:58,239
cards compare to each other in terms of noise then you can skip there otherwise

15
00:00:56,280 --> 00:01:02,079
I'll show you guys the temperatures and power consumption all along for all the

16
00:01:00,039 --> 00:01:07,040
these different solutions just so you guys know for the max power I using the

17
00:01:04,720 --> 00:01:11,600
batch size test as recommended by Sky MTL from Hardware conu I'm going to

18
00:01:09,040 --> 00:01:18,600
repeat that test so that'll give me a nice high GPU temperature as well as a

19
00:01:14,600 --> 00:01:22,000
maximum power load so here we go so our

20
00:01:18,600 --> 00:01:25,560
load power consumption for the GTX 590

21
00:01:22,000 --> 00:01:29,520
clocks in at around 340 watt so we're

22
00:01:25,560 --> 00:01:32,079
just going to record that as 340 and uh

23
00:01:29,520 --> 00:01:37,200
you can see there's a cat investigating it and our maximum temperatures after

24
00:01:34,600 --> 00:01:41,399
running this particular little Benchmark or rather our stable

25
00:01:39,240 --> 00:01:47,040
temperatures are 78 and 79° on each of the gpus so we'll call

26
00:01:44,200 --> 00:01:47,040
that

27
00:01:48,040 --> 00:01:57,360
79 and I really wish that window would go away I don't care I don't care 78 so

28
00:01:53,880 --> 00:02:00,880
there you go or 79 rather um so we'll go

29
00:01:57,360 --> 00:02:03,600
ahead and record that in our

30
00:02:00,880 --> 00:02:11,080
little uh Power W there really is quite a dramatic difference

31
00:02:06,680 --> 00:02:13,080
between the maximum power and the uh and

32
00:02:11,080 --> 00:02:19,519
the minimum power NVIDIA's really done a good job of uh clocking down the GPU

33
00:02:16,800 --> 00:02:23,519
when it's not being used you can see right now it's actually stepping down

34
00:02:21,120 --> 00:02:29,360
right now so it goes all the way down to 51 mahz on the

35
00:02:26,000 --> 00:02:30,480
GPU Focus there you go very nice very

36
00:02:29,360 --> 00:02:36,720
cool all right so there's my idle power consumption for the Radeon 6990 so we'll

37
00:02:34,599 --> 00:02:43,920
call that 132 and I should write that on my handy

38
00:02:39,720 --> 00:02:46,920
little chart at some point and then um

39
00:02:43,920 --> 00:02:49,200
oh hold on let's just do that and then

40
00:02:46,920 --> 00:02:54,159
here are my idle temperatures so it settles in around

41
00:02:50,800 --> 00:02:56,360
41° on the GPU that has less ventilation

42
00:02:54,159 --> 00:03:01,120
so the one at the back of the card and 39° on the GPU at the front of the card

43
00:02:59,440 --> 00:03:07,200
so there there's our idle values so here's the max power

44
00:03:03,319 --> 00:03:11,440
consumption of the radon HD 6990 for the

45
00:03:07,200 --> 00:03:11,440
sake of argument why don't we say around

46
00:03:12,159 --> 00:03:19,120
400 varies let's take the Peaks almost

47
00:03:16,120 --> 00:03:21,840
the peak so we'll say about 405 Watts

48
00:03:19,120 --> 00:03:27,640
cuz it sort of Rises and dips so we're running the 3D Mark test and uh let's

49
00:03:25,159 --> 00:03:31,439
have a look at what we achieved in terms of maximum temperatures

50
00:03:31,840 --> 00:03:39,040
bringing up after burner here so our Max

51
00:03:34,879 --> 00:03:42,280
temps Peak this is artificial um but

52
00:03:39,040 --> 00:03:45,879
they peaked at around 85 and

53
00:03:42,280 --> 00:03:48,720
82° on both of the gpus so here I'm just

54
00:03:45,879 --> 00:03:56,760
going to make it focus focus focus thank you all right so 85 and 82° were my Peak

55
00:03:53,360 --> 00:03:56,760
temperatures on the

56
00:03:57,239 --> 00:04:05,319
gpus so let's call that a 15 50 wat

57
00:04:01,239 --> 00:04:07,159
idle total system power draw and bearing

58
00:04:05,319 --> 00:04:11,599
in mind that all of these numbers for the power are coming through an 80 plus

59
00:04:09,560 --> 00:04:15,480
silver Power Supply so you got to kind of uh factor that in if you want to

60
00:04:13,599 --> 00:04:20,560
figure out how much power they're actually consuming so this is two GTX

61
00:04:17,880 --> 00:04:26,960
580s both of them are stock clocked reference designs and our idle

62
00:04:24,160 --> 00:04:31,960
temperatures are actually come in similar on one of them okay so similar

63
00:04:29,479 --> 00:04:35,840
on this one this is the bottom GPU at 34° and then quite a bit higher so the

64
00:04:34,360 --> 00:04:40,160
reason that second one is quite a bit higher is that there's only that much

65
00:04:37,720 --> 00:04:44,600
space for the fan to draw air in whereas the GTX

66
00:04:41,400 --> 00:04:47,600
590 is getting fresh air for both of the

67
00:04:44,600 --> 00:04:50,000
gpus going out either side so uh let's

68
00:04:47,600 --> 00:04:55,160
get some load temps and load power consumption going on here and then we

69
00:04:52,520 --> 00:05:02,520
will have some commentary at about

70
00:04:57,680 --> 00:05:05,440
465 Watts the GTX 580 solution consumes

71
00:05:02,520 --> 00:05:10,320
the most power out of all of the configurations that are here so that's

72
00:05:08,160 --> 00:05:16,880
uh going with the two dedicated dual gpus rather than a single dual GPU card

73
00:05:14,560 --> 00:05:21,720
uh in both cases consumes more power it is

74
00:05:18,759 --> 00:05:26,479
um the highest performing solution out of all of the ones that we've looked at

75
00:05:23,720 --> 00:05:30,800
so that's to be considered as well although sometimes the margin is

76
00:05:28,479 --> 00:05:34,400
substantial and other times it's less substantial uh no it's fairly

77
00:05:33,000 --> 00:05:42,680
substantial for the most part just looking at uh at these numbers here

78
00:05:37,479 --> 00:05:46,120
anyway so uh yeah I'll show you the load

79
00:05:42,680 --> 00:05:49,080
temps it's me in my pink shirt so for

80
00:05:46,120 --> 00:05:54,639
load temps we're looking at 82 and 77° so that GPU uh that is starving for air

81
00:05:52,039 --> 00:05:59,960
in the middle uh really well does starve for air a little bit and I think that's

82
00:05:58,000 --> 00:06:03,039
pretty much it guys so stay stay tuned and I'm going to show you all the audio

83
00:06:01,240 --> 00:06:08,400
