this video is brought to you by the Corsair Vengeance k70 and k95 these

00:00:04.319 --> 00:00:10.920
fully mechanical keyboards are designed for performance gaming visit Corsair.com

00:00:08.360 --> 00:00:15.080
vengance gaming to learn more all right so we're a little late on a 7990

00:00:12.880 --> 00:00:19.240
unboxing but quite frankly AMD was a little late on releasing the product as

00:00:17.199 --> 00:00:26.320
well because the GTX 690 has been around for quite a while and this right here is

00:00:22.359 --> 00:00:31.279
AMD's direct competitor to the GTX

00:00:26.320 --> 00:00:34.239
690 so a GTX 690 is basically 2 GTX 680s

00:00:31.279 --> 00:00:39.239
and a Radeon 7990 is basically two Radeon 7970 so just like the last

00:00:37.079 --> 00:00:45.440
generation product the 6990 which was released a long time ago this features

00:00:41.719 --> 00:00:49.840
two full Tahiti cores that's 248 stream

00:00:45.440 --> 00:00:54.079
processors as well as a dual 384-bit

00:00:49.840 --> 00:00:57.559
memory bus with 6 GB of gddr5 and that's

00:00:54.079 --> 00:01:01.000
clocked at 6 GHz so remember guys with

00:00:57.559 --> 00:01:03.440
dual GPU Solutions you only get half of

00:01:01.000 --> 00:01:08.280
the RAM as your usable RAM just like you would with any SLI or Crossfire X setup

00:01:06.479 --> 00:01:13.159
now there was a time when I really couldn't recommend dual GPU Solutions so

00:01:10.799 --> 00:01:18.720
or dual GPU cards and that was maybe you know when the 7950 gx2 rolled out yeah

00:01:16.040 --> 00:01:22.400
was super powerful but SLI scaling issues at the time aside the biggest

00:01:20.759 --> 00:01:26.640
problem with it was man did that thing run hot and man was it loud they have

00:01:24.680 --> 00:01:31.840
completely overhauled the way this works so in spite of the fact that this is a

00:01:29.000 --> 00:01:37.079
dual slot card see no triple slot solution it is still capable of running

00:01:33.680 --> 00:01:39.680
at a 950 MHz base clock with a 1 GHz

00:01:37.079 --> 00:01:45.360
boost clock which is faster by a significant margin than a regular 7970

00:01:42.320 --> 00:01:47.600
and almost the same speed as the 150 MHz

00:01:45.360 --> 00:01:53.200
boost clock that we see out of a 7970 GHz Edition so full-fledged gpus only a

00:01:50.719 --> 00:01:58.840
slight reduction in clock speed and a dual slot solution and the card's

00:01:56.000 --> 00:02:04.479
actually quiet in terms of Acoustics it is very similar to the GTX 690 so this

00:02:01.799 --> 00:02:07.720
is enabled by a very very custom cooling solution that is capable of dissipating

00:02:06.759 --> 00:02:15.640
the 375 watt TDP that this card has now that

00:02:11.599 --> 00:02:19.360
375 watt TDP is about 75 Watts more than

00:02:15.640 --> 00:02:22.080
on the GTX 690 but by I mean check this

00:02:19.360 --> 00:02:26.400
out by implementing this cooler that has four heat pipes attached to massive

00:02:24.560 --> 00:02:31.080
aluminum fins so I'll show you the heat pipes here as well so these are coming

00:02:27.760 --> 00:02:32.840
out of both sides as well as a huge

00:02:31.080 --> 00:02:38.519
chunk of copper in the middle here on the vrm solution and more heat pipes

00:02:36.160 --> 00:02:41.760
more copper fins all the way over here more heat pipes hopefully you can see

00:02:40.159 --> 00:02:45.560
those through the uh through the ventilation holes there more heat pipes

00:02:43.680 --> 00:02:49.959
more copper fins almost the entire front of the card is covered in aluminum fins

00:02:48.159 --> 00:02:53.640
copper heat pipes and that chunk of copper right there for vrm so what AMD

00:02:52.159 --> 00:02:57.800
has done is they have implemented this solution with three fans and a massive

00:02:56.120 --> 00:03:02.319
what I'd normally consider to be high-end aftermarket air cooler to to

00:02:59.920 --> 00:03:07.560
keep the card as quiet and as cool as a GTX 690 in spite of the higher TDP one

00:03:06.280 --> 00:03:11.480
of the other things that really helps this card is it does have Tahiti core so

00:03:09.840 --> 00:03:15.200
it features their zeroc core technology which means that when you're idling only

00:03:13.239 --> 00:03:18.879
one of the gpus is even powered on the other one basically goes off and there's

00:03:17.120 --> 00:03:24.640
actually an indicator light here on the back that tells you hey uh I'm turned

00:03:21.680 --> 00:03:28.200
off don't worry about me right now so yeah in addition to zero core technology

00:03:26.799 --> 00:03:32.720
I'd like to take you guys on a bit of a tour of the card itself so on the back

00:03:30.640 --> 00:03:38.840
we find a full back plate as we've come to expect from AMD's very high-end cards

00:03:35.560 --> 00:03:40.680
with two cutouts for the GPU cores

00:03:38.840 --> 00:03:46.000
themselves so you can see exactly where those two Tahiti cores are located you

00:03:43.040 --> 00:03:50.120
can also see the PCI Express 3.06 X interface at the bottom as well as a

00:03:48.280 --> 00:03:54.760
crossfire connector up here at the top only a single Crossfire connector on

00:03:51.799 --> 00:03:59.400
this card because dual GPU cards so often you see guys on the Forum oh I'm

00:03:56.439 --> 00:04:05.040
running for GTX 69 know you aren't because dual GPU cards count as two

00:04:02.239 --> 00:04:10.680
cards in SLI or Crossfire already so you can only link them 2 by two or two times

00:04:08.280 --> 00:04:15.360
two for a total of four gpus that's the maximum supported by both AMD and NVIDIA

00:04:13.400 --> 00:04:22.120
at this time on the top of the card we've got two8 pin connectors so yes it

00:04:18.959 --> 00:04:25.720
consumes a lot of power about 10% more

00:04:22.120 --> 00:04:29.479
than a single 7970 at idle and somewhere

00:04:25.720 --> 00:04:30.240
between a GTX 690 and dual 797s under

00:04:29.479 --> 00:04:35.320
low this is in large part due to the very

00:04:33.199 --> 00:04:40.360
selective binning process that AMD goes through in order to get two gpus that

00:04:38.080 --> 00:04:46.479
can go on a single card and be running at like a gigahertz when they're boosted

00:04:42.720 --> 00:04:48.440
up and not go over that 375 watt power

00:04:46.479 --> 00:04:54.039
limit on the rest of the top of the card you've got a bio switch up here as well

00:04:50.960 --> 00:04:56.520
as just a very very Sleek looking but

00:04:54.039 --> 00:05:00.360
well ventilated cooler shroud so one thing to note about these Open Air

00:04:58.160 --> 00:05:05.080
Design coolers is that while they do keep the card itself very cool they

00:05:02.520 --> 00:05:08.720
exhaust the heat into your case so down here along the bottom of the card you

00:05:06.400 --> 00:05:15.240
can see it's more open ventilation so unlike a GTX 690 or even a Radeon 69 H

00:05:12.639 --> 00:05:21.360
actually 6990 went both ways uh so unlike a 4870 X2 it's going to exhaust

00:05:18.680 --> 00:05:24.960
heat into your case as opposed to just out the ventilation holes at the back

00:05:23.240 --> 00:05:28.639
you will get a little bit coming out the back but it's yeah it's going to be it's

00:05:27.479 --> 00:05:33.080
going to be quite limited so you're going to want to make sure you have a case with great ventilation on the back

00:05:31.479 --> 00:05:38.600
we can also see the io so we've got a DVI port as well as four mini display

00:05:36.160 --> 00:05:44.479
port ports so you can easily run a maxed out ifinity setup off of this single

00:05:42.120 --> 00:05:48.319
card so the real question here is for a $1,000 graphics card yeah I'm going to

00:05:46.400 --> 00:05:52.960
mention price I usually don't because sometimes they change not expecting this

00:05:50.280 --> 00:05:57.080
one to change anytime soon what is the compelling value ad because you can

00:05:54.800 --> 00:06:00.560
either get two Tahiti cores or basically a trip to Tahiti and it's up to you

00:05:58.680 --> 00:06:02.919
which one of those is better so there's three cards at that price point there's

00:06:02.160 --> 00:06:07.080
the $ 7990 there's the GTX 690 and there's the

00:06:05.639 --> 00:06:14.160
GTX Titan these are very different solutions so 690 being a bit of an older

00:06:09.360 --> 00:06:15.759
card has 2x 2 gig memory frame buffers

00:06:14.160 --> 00:06:19.800
so the problem with that is it's just not really enough memory to run at

00:06:17.639 --> 00:06:23.319
something like a 4K resolution and expect to be able to put sort of high

00:06:21.800 --> 00:06:30.120
res texture packs or anything like that on your games GTX Titan has 6 gigs of

00:06:26.840 --> 00:06:31.680
GPU memory but it's a single single GPU

00:06:30.120 --> 00:06:35.160
solution so while it gives more consistent performance it doesn't

00:06:33.199 --> 00:06:40.440
necessarily have the raw horsepower that something like 7990 does or something

00:06:37.319 --> 00:06:41.919
like gtx690 does okay which puts 7990

00:06:40.440 --> 00:06:48.240
somewhere in the middle where it has three gigs of memory that's usable okay

00:06:44.360 --> 00:06:49.919
so 6 gigs total it has slightly more

00:06:48.240 --> 00:06:55.599
well it has significantly more power than a GTX Titan coming in very close to

00:06:52.039 --> 00:06:57.759
something like a GTX 690 and but there's

00:06:55.599 --> 00:07:01.240
more okay so okay so it has higher power consumption than 690 significantly

00:06:59.599 --> 00:07:05.440
higher power of consumption than Titan it's about the same volume as 690

00:07:03.039 --> 00:07:10.759
whereas Titan is quieter and it consumes more power and outputs more heat than

00:07:07.319 --> 00:07:12.960
either of those two cards but AMD says

00:07:10.759 --> 00:07:16.840
never settle and never settle indeed this card comes with eight games or at

00:07:14.759 --> 00:07:21.199
least it did at launch and AMD will continue bu all appearances to support

00:07:19.560 --> 00:07:24.440
never settle so if you get a card that's $1,000 but it comes with a few hundred

00:07:23.479 --> 00:07:28.199
worth of games is that a compelling value add to

00:07:26.800 --> 00:07:32.639
you are you willing to sacrifice a little bit on your power bill over the next little while or have a slightly

00:07:30.840 --> 00:07:36.800
hotter room or you have to run your air conditioning higher or whatever else

00:07:34.520 --> 00:07:42.160
it's totally up to you and that is all aside from the FCAT issue remember guys

00:07:39.720 --> 00:07:45.879
frame capture has become the new deao standard for how to Benchmark graphics

00:07:44.159 --> 00:07:50.120
cards that's where you're looking at the actual output frames as opposed to the

00:07:48.240 --> 00:07:53.720
frames that are requested to be drawn by the card which is what a program like

00:07:51.680 --> 00:07:59.000
fraps does and AMD has a new driver coming that will resolve the issue with

00:07:56.280 --> 00:08:03.039
stuttering with their dual GPU Solutions but we haven't seen it yet so it's hard

00:08:01.039 --> 00:08:06.319
to say exactly how that's going to perform so I know that was a lot of

00:08:04.560 --> 00:08:10.520
information in a very short period of time but if you're shopping for $1,000

00:08:08.599 --> 00:08:14.720
graphics card basically what you need to know is AMD's higher performance driver

00:08:12.520 --> 00:08:19.080
is coming it does consume more power and output more heat but it comes with a

00:08:16.639 --> 00:08:22.199
whack ton of games in the box which might make that a compelling solution

00:08:20.560 --> 00:08:26.879
