--> 00:00:15,560 www.cool.com teamor curse for more details welcome to my unboxing and first 4 00:00:13,280 --> 00:00:20,439 look at the Gigabyte HD 7790 this is a 2 gig card and it is an 5 00:00:18,760 --> 00:00:26,840 overclocked card with their windforce cooler now as you might imagine the 7790 6 00:00:23,680 --> 00:00:30,480 exists somewhere between the 7770 and 7 00:00:26,840 --> 00:00:32,520 the 7850 it uses a very similar 8 00:00:30,480 --> 00:00:38,399 overall architecture to the rest of their gcn or a graphics core next 9 00:00:36,079 --> 00:00:42,640 architecture but it's basically just sort of everything that those cards are 10 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 11 00:00:45,399 --> 00:00:53,399 it does support all the usual AMD Radeon features so direct X11 ifinity with up 12 00:00:51,000 --> 00:00:57,879 to four displays off of this particular card and then let's talk a little bit 13 00:00:55,559 --> 00:01:02,879 about gigabytes windforce cooler so their brand new windforce 2X is equipped 14 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 15 00:01:05,600 --> 00:01:10,680 heat pipes are better it's just so you guys know and the triangle cool 16 00:01:09,040 --> 00:01:14,799 integrates a patented triangle-shaped aluminum block into the aluminum 17 00:01:12,960 --> 00:01:19,280 Extrusion module which enhances the speed of heat dissipation more 18 00:01:16,400 --> 00:01:24,799 effectively so that's a block right there which basically just kind of moves 19 00:01:21,000 --> 00:01:26,439 the air um from going straight down to 20 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 21 00:01:28,240 --> 00:01:33,759 what they put inside this particular card is is overclocked from a standard 1 22 00:01:31,280 --> 00:01:41,200 GHz to uh 1.75 gz so 1075 MHz comes with a quick 23 00:01:38,439 --> 00:01:46,799 start guide a Molex to PCI Express power adapter a driver disc which you should 24 00:01:43,079 --> 00:01:49,280 throw away some foam as well as a video 25 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 26 00:01:51,079 --> 00:01:59,520 tape yay unboxings how we love them 27 00:01:55,640 --> 00:02:00,960 so there we go and the card itself is 28 00:01:59,520 --> 00:02:05,159 covered in a whole bunch of little protective coverings so check this out 29 00:02:03,920 --> 00:02:09,640 this is what they're talking about with their triangle thing so rather than just 30 00:02:07,360 --> 00:02:13,440 taking the airf flow that goes down directly through the F onto the PCB what 31 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 32 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 33 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 34 00:02:25,280 --> 00:02:31,120 think about it this way guys if you have fins like this and air goes straight 35 00:02:28,879 --> 00:02:34,599 through them then the air passes over this much of the metal okay whereas if 36 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 37 00:02:36,400 --> 00:02:41,400 pass over this much of the metal effectively making the heat dissipation 38 00:02:40,040 --> 00:02:44,879 more efficient in theory this should also add a little bit of extra noise a 39 00:02:43,080 --> 00:02:50,440 little bit more turbulence but when you're using large uh slow rotating fans 40 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 41 00:02:53,560 --> 00:02:59,840 there you go more RAM on the back has the usual compliment of features I mean 42 00:02:58,239 --> 00:03:05,599 there's not really much that's Chang changed with 7790 that's probably why 43 00:03:02,319 --> 00:03:07,360 AMD opted not to go with an 8,000 series 44 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 45 00:03:10,040 --> 00:03:16,200 connectors that I told you guys about which supports up to four displays so 46 00:03:13,440 --> 00:03:20,799 you've got your uh single analog output there remember guys DVID is not the same 47 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 48 00:03:22,920 --> 00:03:28,360 port some external exhaust however due to the design of this cooler not a whole 49 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 50 00:03:30,920 --> 00:03:36,879 what must be some vrm components yeah it 51 00:03:34,239 --> 00:03:41,200 looks like they are it looks like um what gigabytes actually done is they've 52 00:03:38,640 --> 00:03:46,000 taken the 12vt power that comes in here routed it all the way across the card 53 00:03:43,360 --> 00:03:49,599 here where it'll be redistributed back this way because you can see this part 54 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 55 00:03:51,319 --> 00:03:57,360 cards where manufacturers are actually because they don't even need all this 56 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 57 00:03:59,239 --> 00:04:04,159 just leaving a lot of blank PCB area so 58 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 59 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 60 00:04:10,480 --> 00:04:16,680 human pinky finger if nothing else and then a very solid block of aluminum 61 00:04:14,920 --> 00:04:21,000 makes up the rest of that cooler design so this is a relatively expensive cooler 62 00:04:18,639 --> 00:04:24,600 compared to what a reference design card would ship with so that heat pipe is 63 00:04:22,479 --> 00:04:30,400 carrying away from the solid block cooler over to the more uh thin fin type 64 00:04:28,120 --> 00:04:34,720 of Ray cooler where the second fan is doing most of its work a single PCI 65 00:04:32,960 --> 00:04:38,720 Express six pin power connector is provided and there is your Crossfire 66 00:04:37,199 --> 00:04:44,400 connector so the car does support two-way Crossfire but not three-way or 67 00:04:41,759 --> 00:04:49,600 moreway configurations
