1
00:00:07,279 --> 00:00:15,759
well it's semiformal review time again guys this is the GeForce GTX 680 from

2
00:00:12,920 --> 00:00:21,480
Galaxy this is the new flagship single GPU graphics card from NVIDIA by our

3
00:00:18,199 --> 00:00:25,560
friends at Galaxy this is a 2 GB uh

4
00:00:21,480 --> 00:00:29,039
frame buffer over 1 GHz core clock and

5
00:00:25,560 --> 00:00:31,320
over 6 GHz memory clock graphics card it

6
00:00:29,039 --> 00:00:37,440
has two six pin power connectors it has a PCI Express 3.0 16x slot is compatible

7
00:00:35,120 --> 00:00:42,120
with uh the variety of SLI configurations that are available using

8
00:00:39,040 --> 00:00:44,200
these two SLI ports and it is on the

9
00:00:42,120 --> 00:00:49,039
latest manufacturing process enabling it to be phenomenally power efficient and

10
00:00:46,239 --> 00:00:54,079
my camera won't focus and perform like the bees knes and supposedly although I

11
00:00:51,320 --> 00:00:59,039
have not yet tested this card it also overclocks

12
00:00:55,840 --> 00:01:00,280
like like wo like pretty good so in

13
00:00:59,039 --> 00:01:06,360
terms of cards that I'm going to be testing against I have a total of seven

14
00:01:03,079 --> 00:01:10,479
cards to be tested so I've got the 7970

15
00:01:06,360 --> 00:01:12,560
from AMD this is a stock bone reference

16
00:01:10,479 --> 00:01:18,560
card to be compared against the reference GTX 680 I have a sapphire

17
00:01:16,000 --> 00:01:23,000
hd7950 so this is an aftermarket card you're going to see this one's strengths

18
00:01:20,240 --> 00:01:26,040
when we get to things like the Acoustics and temperature testing that's going to

19
00:01:24,640 --> 00:01:31,479
be a separate video though this is the performance video we've got the GTX 590

20
00:01:28,920 --> 00:01:36,320
this is a last generation dual GPU card to compare against the current

21
00:01:32,799 --> 00:01:38,560
generation single GPU card uh 6990 so

22
00:01:36,320 --> 00:01:45,320
this is a last generation dual GPU card from AMD then I want to compare the 680

23
00:01:41,880 --> 00:01:49,000
against the 580 as well as the previous

24
00:01:45,320 --> 00:01:51,200
generation GTX 570 so that we can see

25
00:01:49,000 --> 00:01:54,680
where it falls in terms of the overall performance stack now you see 3D Vision

26
00:01:53,399 --> 00:02:00,719
glasses there that's going to be a separate review this is going to be my

27
00:01:56,680 --> 00:02:03,039
2D performance at 1080p review since

28
00:02:00,719 --> 00:02:07,600
that is what the majority of monitors are supporting these days that is what

29
00:02:05,000 --> 00:02:12,239
we are going to be focused on how now I did change a couple things so instead of

30
00:02:10,319 --> 00:02:16,440
using my normal benchmarking settings for the games that I ran I did alter

31
00:02:14,599 --> 00:02:20,959
things a little bit so for Battlefield 3 I'm using the ultra preset for crisis 2

32
00:02:18,959 --> 00:02:25,640
I'm using Ultra Plus highres textures Witcher 2 is ultra plus the vsync is off

33
00:02:23,400 --> 00:02:29,640
Dirt 3 is four times anti-aliasing with high and Ultra we available Batman

34
00:02:28,280 --> 00:02:33,840
Arkham City is going to be using four time multi sample anti-aliasing this is

35
00:02:32,239 --> 00:02:38,800
important which kind of anti-aliasing I'm using because this new card supports

36
00:02:36,319 --> 00:02:44,120
a couple of modes of anti-aliasing that have some distinct advantage txaa and

37
00:02:41,959 --> 00:02:50,000
FXAA but we are not going to be using those for the purposes of this review

38
00:02:46,280 --> 00:02:52,040
this will be Apples to Apples phys X off

39
00:02:50,000 --> 00:02:57,280
okay and Skyrim will be at Ultra with four times msaa 8 times AF vsync forced

40
00:02:55,319 --> 00:03:02,280
off through the inii file and the highres texture pack the official

41
00:02:59,879 --> 00:03:06,239
highres texture pack you can see I've actually finished the benchmarks for all

42
00:03:04,280 --> 00:03:09,760
the other cards this takes forever guys it takes absolutely forever and you can

43
00:03:08,280 --> 00:03:14,560
also see a sneak peek of all the different scenarios I'm planning to run

44
00:03:11,680 --> 00:03:21,120
1080p review ah yes my test bench so this is my uh lg8 2011 test bench with a

45
00:03:18,640 --> 00:03:25,200
363k 30 30 3930k

46
00:03:22,760 --> 00:03:28,799
3930k uh this is running at stock speed so I haven't made any changes to that

47
00:03:26,760 --> 00:03:35,239
guy right there 16 gigs of Kingston hyperx memory a Seuss P9 x79 Deluxe

48
00:03:33,040 --> 00:03:41,480
motherboard as well as of course our h100 for my boot SSD I'm using a mushkin

49
00:03:38,720 --> 00:03:47,239
Kronos Deluxe my steam Drive is running off here and for my power supply I'm

50
00:03:43,519 --> 00:03:49,439
using an ocz ZX Series 1250 W modular

51
00:03:47,239 --> 00:03:57,920
power supply that pretty much covers it for the test bench itself and it is time

52
00:03:54,480 --> 00:04:00,439
to start testing this card because yes

53
00:03:57,920 --> 00:04:04,280
that is the line that is still blank has not yet been on the test pinch I'll be

54
00:04:01,840 --> 00:04:11,079
using the latest drivers on all cards so that is uh 12.2 for the AMD cards and

55
00:04:08,040 --> 00:04:12,799
then the hold on which one is this I'll

56
00:04:11,079 --> 00:04:18,160
have to look because it's going to be a different driver for the new card than

57
00:04:15,360 --> 00:04:24,440
it is for the other card so 29610 for every GeForce card except the 680 which

58
00:04:20,919 --> 00:04:26,880
will'll be using the 300 whatever it is

59
00:04:24,440 --> 00:04:34,960
sorry for the long intro guys here we go here's Rumble investigating my uh

60
00:04:30,759 --> 00:04:38,560
test bench while the GTX 680 runs 3D

61
00:04:34,960 --> 00:04:43,479
Mark 11 my first test of the

62
00:04:38,560 --> 00:04:43,479
night what a brat he is

63
00:05:02,639 --> 00:05:05,800
oh he's stepping on a

64
00:05:06,360 --> 00:05:12,440
6990 get off there go on get

65
00:05:19,240 --> 00:05:25,520
get here we are in the middle of a combined test so to give you guys some

66
00:05:22,960 --> 00:05:31,600
idea how power efficient this guy is check this out it's pulling less than

67
00:05:28,440 --> 00:05:34,800
280 Wat from the wall so that's probably

68
00:05:31,600 --> 00:05:37,360
around 250 WTS of actual power

69
00:05:34,800 --> 00:05:43,199
consumption with the 6 core processor high-end single graphics card and uh

70
00:05:40,479 --> 00:05:47,840
throughout all of this the thing is darn near silent as

71
00:05:45,960 --> 00:05:55,199
well but more on that later a score of 3172 puts it right in line with the rest

72
00:05:50,759 --> 00:05:56,880
of or with uh the GTX 590 in 3D Mark 11

73
00:05:55,199 --> 00:06:03,440
um although significantly behind the 6990 let's see how things go in Real

74
00:06:00,199 --> 00:06:06,039
World gameplay scenarios so as I always

75
00:06:03,440 --> 00:06:09,639
do I'm using well I gu guess I shouldn't say always because Dirt 3 is using a

76
00:06:07,840 --> 00:06:13,840
canned Benchmark and Batman Arkham City is using a canned Benchmark Battlefield

77
00:06:11,840 --> 00:06:18,080
3 is using my usual run through of the comrades beginning of the comrades level

78
00:06:16,000 --> 00:06:22,880
crisis 2 is using my usual run through of the first camp in crisis 2 The

79
00:06:20,919 --> 00:06:26,240
Witcher 2 is using a run through where I go up uh little Hill I fight some guys

80
00:06:25,039 --> 00:06:32,720
go through a building and then come into a courtyard where I fight some other guys and Skyrim uh the town is called

81
00:06:31,039 --> 00:06:36,280
white white run I think something like that and I do a couple laps of White Run

82
00:06:34,840 --> 00:06:41,360
looking at some people looking at some fire looking around so uh stay tuned for

83
00:06:38,880 --> 00:06:47,120
real world gaming benchmarks and the first results are in

84
00:06:43,840 --> 00:06:49,400
so while posting power results that are

85
00:06:47,120 --> 00:06:56,440
very similar to the incredibly power efficient 7970 per it posts also better

86
00:06:53,919 --> 00:07:01,599
average frame rate and the same minimum frame rate compared to the 7970 it

87
00:06:59,639 --> 00:07:07,960
actually performs similarly to the GTX 590 once again while consuming over 150

88
00:07:05,479 --> 00:07:11,440
watts less power at the wall uh something to note here is due to the

89
00:07:09,759 --> 00:07:15,879
very high graphical settings both the 580 and the 570 kind of choked on this

90
00:07:13,520 --> 00:07:19,960
Benchmark so you can see there is an enormous difference between this new

91
00:07:17,639 --> 00:07:25,479
generation premium card and the last generation one now crisis 2 is less of a

92
00:07:23,160 --> 00:07:30,720
clear win against the lower price 7970 but it is still a win nonetheless

93
00:07:28,520 --> 00:07:34,720
so it takes the performance Crown again in crisis 2 something that I've noticed

94
00:07:32,520 --> 00:07:39,039
at this point is that this is actually the first reference GeForce card that

95
00:07:36,960 --> 00:07:43,080
I've encountered that does have coil wi so it's a little bit of a high-pitched

96
00:07:41,039 --> 00:07:46,520
noise that you experience under load with the card and and I'm talking about

97
00:07:44,800 --> 00:07:50,159
in games not in folding at home or anything like that um this is something

98
00:07:48,440 --> 00:07:54,560
that I've experienced on pretty much every reference AMD card for the last

99
00:07:52,080 --> 00:08:00,159
few Generations but hadn't seen on a GeForce card as yet so the 680 does does

100
00:07:58,440 --> 00:08:05,080
exhibit this noise exhibit it um make it The Witcher 2

101
00:08:03,280 --> 00:08:12,360
looks like a tight battle between the 7970 in terms of average FPS and uh the

102
00:08:09,720 --> 00:08:16,800
GTX 680 but in actuality you can see my notes here from when I was testing this

103
00:08:14,560 --> 00:08:23,599
30fps which is considered sort of the minimum of playable was very unplayable

104
00:08:19,639 --> 00:08:26,800
felt very laggy whereas this 30f 32 FPS

105
00:08:23,599 --> 00:08:29,080
actually felt significantly better so uh

106
00:08:26,800 --> 00:08:33,640
so yeah that puts the GTX 680 as far as a single card Solutions go definitely at

107
00:08:32,000 --> 00:08:39,640
the top this is another title where the last generation products from NVIDIA the

108
00:08:36,120 --> 00:08:41,599
uh 580 and the 570 really struggled uh

109
00:08:39,640 --> 00:08:47,440
whether that's due to having less video memory remember the new card has 2 gigs

110
00:08:43,519 --> 00:08:50,040
versus 1.5 and 1.28 on those older cards

111
00:08:47,440 --> 00:08:55,040
um and also has significantly more power but uses a similar amount of

112
00:08:52,720 --> 00:08:59,640
power since I haven't shown you guys my Skyrim test sequence before I'll take

113
00:08:57,160 --> 00:09:04,079
this opportunity to do that so I'm I'm just running around this town following

114
00:09:02,360 --> 00:09:09,360
the same path every time looking off into the distance a little bit I always

115
00:09:07,360 --> 00:09:13,399
stop and look down at this camp for a couple seconds running very smoothly

116
00:09:11,200 --> 00:09:17,160
although I did see a flicker there yeah there's another one so I've experienced

117
00:09:15,040 --> 00:09:22,440
flickering now on the 6990 uh

118
00:09:19,040 --> 00:09:24,040
7970 and uh and this card out of all the

119
00:09:22,440 --> 00:09:29,399
cards that were tested I've seen this flickering on three of them so uh that's

120
00:09:27,600 --> 00:09:35,160
very frustrating definitely detracts from gameplay now I could probably get

121
00:09:32,519 --> 00:09:39,079
the flickering to go away by changing some graphical settings on any of those

122
00:09:36,800 --> 00:09:44,680
given cards but since what I'm trying to do is find a similarly demanding

123
00:09:41,360 --> 00:09:46,399
situation for each of the cards I don't

124
00:09:44,680 --> 00:09:50,320
really want to change any settings and I stop and look at this guard for a second

125
00:09:48,560 --> 00:09:54,720
stop and look at this guard for a second get my cat to go

126
00:09:51,880 --> 00:09:57,839
away um and then off we go around again so while I'm doing the second lap I'll

127
00:09:56,360 --> 00:10:01,519
talk about some other things so first of all is my power testing methodology I

128
00:10:00,360 --> 00:10:05,839
don't know if you guys can see it through the camera yeah you can you can see my power meter so what I'm doing is

129
00:10:04,480 --> 00:10:10,480
while I'm benchmarking I'm keeping an eye on that and what I'm looking for is

130
00:10:08,160 --> 00:10:15,880
sort of something along the lines of of a consistent Peak so if I see it Spike

131
00:10:13,360 --> 00:10:20,040
to 320 once but then you know otherwise hover more around the when it's when

132
00:10:17,839 --> 00:10:24,399
it's under high load around the 300 watt range 305 watt range then that's where

133
00:10:22,800 --> 00:10:28,760
I'll take the reading for that card yeah it's very approximate see this one I'd

134
00:10:26,800 --> 00:10:33,560
probably go with 305 based on what I've seen so far that's something that that's

135
00:10:30,839 --> 00:10:37,560
a peak that I've hit several times so you can see Skyrim isn't running 100%

136
00:10:35,680 --> 00:10:42,200
correctly on this card maybe that's in part due to the early drivers could be

137
00:10:39,440 --> 00:10:47,000
settings um I also want oh yeah so yeah Power and temperatures instead of

138
00:10:43,800 --> 00:10:50,040
measuring power and temps uh with like a

139
00:10:47,000 --> 00:10:52,800
um a synthetic Benchmark what I'm doing

140
00:10:50,040 --> 00:10:58,399
is I'm looking at it in all of the applications that I'm testing in order

141
00:10:54,880 --> 00:10:59,920
to get a good solid um average so this

142
00:10:58,399 --> 00:11:03,000
benchmark's done you can tell cuz the fraps counter has reappeared so I'll

143
00:11:01,680 --> 00:11:09,040
definitely have to make some notes about the flickering on this one and let's go have a look at the results temperature

144
00:11:06,839 --> 00:11:13,200
monitoring is done using MSI afterburner so I'm looking for the peak temperature

145
00:11:10,600 --> 00:11:16,720
which looks like it was 77 here which is consistent with all the other ones this

146
00:11:14,880 --> 00:11:23,480
kind of stands to reason because what the GTX 680 does is it actually uses its

147
00:11:20,639 --> 00:11:28,720
thermal uh thermal envelope to determine how much power to throw at a particular

148
00:11:26,760 --> 00:11:33,880
game uh so it'll actually scale its clock speed let me see if uh if

149
00:11:31,120 --> 00:11:38,959
afterburner is correctly yeah look at that it is monitoring core clock

150
00:11:37,040 --> 00:11:43,120
whoops oh no I don't think it's monitoring that correctly well let's not

151
00:11:41,399 --> 00:11:48,079
worry about that for now then I know that um EVGA Precision is already

152
00:11:45,880 --> 00:11:52,440
updated for the GTX 680 but none of the other applications are right now so 680

153
00:11:50,720 --> 00:11:58,160
comes right oh hold on maybe there was another card yeah flickering on the

154
00:11:54,519 --> 00:12:00,880
590 the 6990 and the 7970 so it looks

155
00:11:58,160 --> 00:12:06,720
like all of the all the the king performers

156
00:12:03,680 --> 00:12:08,440
flickering um had the same issue with

157
00:12:06,720 --> 00:12:16,720
this game so there there you have it so that's the 680 590 580 570 6990 7970 and

158
00:12:14,360 --> 00:12:21,399
7950 so this is in terms of sheer performance a clear win for the GTX 680

159
00:12:19,519 --> 00:12:27,079
where it actually beats out everything in this test by slim margin including

160
00:12:24,600 --> 00:12:30,880
the GTX 590 it definitely felt significantly smoother during use and

161
00:12:29,199 --> 00:12:34,519
once again that impressive power consumption is right there and we're

162
00:12:32,760 --> 00:12:39,560
done here Batman Arkham City which ironically is uh the way it's meant to

163
00:12:36,639 --> 00:12:46,000
be played title is the first game we've seen where the GTX 680 is actually

164
00:12:42,279 --> 00:12:47,639
outperformed by the Radeon hd7970 could

165
00:12:46,000 --> 00:12:50,240
be driver issues because one thing I noticed here is that the power

166
00:12:49,199 --> 00:12:55,279
consumption of the card was significantly lower than it was in the

167
00:12:52,800 --> 00:13:01,040
other games so what that means to me is maybe the GPU core clock isn't scaling

168
00:12:57,880 --> 00:13:02,240
in order to uh to reach its maximum TDP

169
00:13:01,040 --> 00:13:08,079
or maybe there's some driver optimizations that can squeeze some more performance out of this game I guess we

170
00:13:05,480 --> 00:13:12,839
will have to wait and see so just a reminder this is the 680 the 590 the 580

171
00:13:11,040 --> 00:13:19,160
the 570 the 6990 the 7970 and the

172
00:13:16,160 --> 00:13:21,720
7950 which is almost equal with the GTX

173
00:13:19,160 --> 00:13:26,160
680 in this particular title so that pretty much concludes my performance

174
00:13:24,120 --> 00:13:29,880
benchmarks so here we go I'm just going to freeze frame for you guys yeah I

175
00:13:28,120 --> 00:13:33,800
could make graphs but I really don't think that's likely to happen oh idle

176
00:13:31,639 --> 00:13:39,240
power so idle power all of these new generation cards the 680 as well as the

177
00:13:36,480 --> 00:13:43,800
7970 and the 7950 are significant improvements over their last generation

178
00:13:41,399 --> 00:13:49,639
brethren in terms of idle power idle temperatures remain for the most part

179
00:13:46,199 --> 00:13:54,320
fairly similar though uh so let's go

180
00:13:49,639 --> 00:13:57,560
ahead and start hiding row so in review

181
00:13:54,320 --> 00:13:59,880
there's the cards and Battlefield 3 as

182
00:13:57,560 --> 00:14:04,600
including the power and temperatures of all of these

183
00:14:01,240 --> 00:14:07,959
games and we can go ahead and hide those

184
00:14:04,600 --> 00:14:11,759
ones there's crisis 2 including power

185
00:14:07,959 --> 00:14:11,759
temperature minmax and average

186
00:14:13,040 --> 00:14:20,720
numbers The Witcher two so there's our power attempts min

187
00:14:18,120 --> 00:14:24,680
max average remember guys this was completely unplayable whether that's a

188
00:14:22,320 --> 00:14:31,040
driver issue or whatever else this 30 was not playable unlike the 32 here next

189
00:14:28,440 --> 00:14:31,040
We've Got Dirt

190
00:14:36,079 --> 00:14:45,279
three Batman Arkham City which was a Radeon dominated test

191
00:14:41,639 --> 00:14:48,680
this time around well other than the 590

192
00:14:45,279 --> 00:14:51,199
but whatever guys all right and finally

193
00:14:48,680 --> 00:14:57,160
Skyrim which had weird flickering on these four cards and was otherwise uh

194
00:14:55,120 --> 00:15:02,759
fairly normal so thank you for checking out my performance review of the GeForce

195
00:14:59,639 --> 00:15:07,199
GTX 680 in a single card configuration

196
00:15:02,759 --> 00:15:09,480
at 1080p with high SL ultimate or Ultra

197
00:15:07,199 --> 00:15:13,000
graphic settings on a variety of games don't forget to subscribe to lus
