00:00:13.280 --> 00:00:20.439
look at the Gigabyte HD 7790 this is a 2 gig card and it is an

00:00:18.760 --> 00:00:26.840
overclocked card with their windforce cooler now as you might imagine the 7790

00:00:23.680 --> 00:00:30.480
exists somewhere between the 7770 and

00:00:26.840 --> 00:00:32.520
the 7850 it uses a very similar

00:00:30.480 --> 00:00:38.399
overall architecture to the rest of their gcn or a graphics core next

00:00:36.079 --> 00:00:42.640
architecture but it's basically just sort of everything that those cards are

00:00:41.039 --> 00:00:47.680
except a little less or a little bit more if that makes any sense to you guys

00:00:45.399 --> 00:00:53.399
it does support all the usual AMD Radeon features so direct X11 ifinity with up

00:00:51.000 --> 00:00:57.879
to four displays off of this particular card and then let's talk a little bit

00:00:55.559 --> 00:01:02.879
about gigabytes windforce cooler so their brand new windforce 2X is equipped

00:01:00.359 --> 00:01:07.240
with a new triangle cool design two 100 mm pwm fans an 8 mil heat pipe thicker

00:01:05.600 --> 00:01:10.680
heat pipes are better it's just so you guys know and the triangle cool

00:01:09.040 --> 00:01:14.799
integrates a patented triangle-shaped aluminum block into the aluminum

00:01:12.960 --> 00:01:19.280
Extrusion module which enhances the speed of heat dissipation more

00:01:16.400 --> 00:01:24.799
effectively so that's a block right there which basically just kind of moves

00:01:21.000 --> 00:01:26.439
the air um from going straight down to

00:01:24.799 --> 00:01:29.520
going through the fins at an angle which is actually sort of smart so let's see

00:01:28.240 --> 00:01:33.759
what they put inside this particular card is is overclocked from a standard 1

00:01:31.280 --> 00:01:41.200
GHz to uh 1.75 gz so 1075 MHz comes with a quick

00:01:38.439 --> 00:01:46.799
start guide a Molex to PCI Express power adapter a driver disc which you should

00:01:43.079 --> 00:01:49.280
throw away some foam as well as a video

00:01:46.799 --> 00:01:53.200
card itself in an anti-static bag the anti-static bag is sealed by a piece of

00:01:51.079 --> 00:01:59.520
tape yay unboxings how we love them

00:01:55.640 --> 00:02:00.960
so there we go and the card itself is

00:01:59.520 --> 00:02:05.159
covered in a whole bunch of little protective coverings so check this out

00:02:03.920 --> 00:02:09.640
this is what they're talking about with their triangle thing so rather than just

00:02:07.360 --> 00:02:13.440
taking the airf flow that goes down directly through the F onto the PCB what

00:02:11.800 --> 00:02:19.080
they're effectively doing here is they're changing the direction a little bit although I have to wonder how much

00:02:17.120 --> 00:02:22.800
of it is being Chang oh yeah no a fair amount so the triangle piece goes all

00:02:20.879 --> 00:02:26.640
the way out to here and all the way out to about here so what that means is

00:02:25.280 --> 00:02:31.120
think about it this way guys if you have fins like this and air goes straight

00:02:28.879 --> 00:02:34.599
through them then the air passes over this much of the metal okay whereas if

00:02:33.239 --> 00:02:38.319
you have a fin like this and the air goes through this way then it gets to

00:02:36.400 --> 00:02:41.400
pass over this much of the metal effectively making the heat dissipation

00:02:40.040 --> 00:02:44.879
more efficient in theory this should also add a little bit of extra noise a

00:02:43.080 --> 00:02:50.440
little bit more turbulence but when you're using large uh slow rotating fans

00:02:48.400 --> 00:02:56.120
I suspect it's not going to be that much of an issue now this particular card see

00:02:53.560 --> 00:02:59.840
there you go more RAM on the back has the usual compliment of features I mean

00:02:58.239 --> 00:03:05.599
there's not really much that's Chang changed with 7790 that's probably why

00:03:02.319 --> 00:03:07.360
AMD opted not to go with an 8,000 series

00:03:05.599 --> 00:03:11.480
uh name for this particular card so it's still PCI Express 3.0 there's the

00:03:10.040 --> 00:03:16.200
connectors that I told you guys about which supports up to four displays so

00:03:13.440 --> 00:03:20.799
you've got your uh single analog output there remember guys DVID is not the same

00:03:18.280 --> 00:03:25.159
as DVI you can't do dual VGA off this card you've got HDMI as well as display

00:03:22.920 --> 00:03:28.360
port some external exhaust however due to the design of this cooler not a whole

00:03:26.760 --> 00:03:34.239
lot of heat is going to be coming off of there you've also got a cooler here for

00:03:30.920 --> 00:03:36.879
what must be some vrm components yeah it

00:03:34.239 --> 00:03:41.200
looks like they are it looks like um what gigabytes actually done is they've

00:03:38.640 --> 00:03:46.000
taken the 12vt power that comes in here routed it all the way across the card

00:03:43.360 --> 00:03:49.599
here where it'll be redistributed back this way because you can see this part

00:03:47.439 --> 00:03:53.840
of the PCB is actually quite bare and we've seen this a fair bit on recent

00:03:51.319 --> 00:03:57.360
cards where manufacturers are actually because they don't even need all this

00:03:55.400 --> 00:04:02.480
PCB space but they don't want the card to look like a little baby card they're

00:03:59.239 --> 00:04:04.159
just leaving a lot of blank PCB area so

00:04:02.480 --> 00:04:08.000
there you have it there's that 8 mil heat pipe that uh that I was talking

00:04:05.720 --> 00:04:13.000
about before you can see it's like you know pretty huge compared to there's a

00:04:10.480 --> 00:04:16.680
human pinky finger if nothing else and then a very solid block of aluminum

00:04:14.920 --> 00:04:21.000
makes up the rest of that cooler design so this is a relatively expensive cooler

00:04:18.639 --> 00:04:24.600
compared to what a reference design card would ship with so that heat pipe is

00:04:22.479 --> 00:04:30.400
carrying away from the solid block cooler over to the more uh thin fin type

00:04:28.120 --> 00:04:34.720
of Ray cooler where the second fan is doing most of its work a single PCI

00:04:32.960 --> 00:04:38.720
Express six pin power connector is provided and there is your Crossfire

00:04:37.199 --> 00:04:44.400
connector so the car does support two-way Crossfire but not three-way or

00:04:41.759 --> 00:04:49.600
moreway configurations thank you for checking out this unboxing of the HD
