CM Storm Preferred Choice of mice headsets and mechanical keyboards of curse gaming visit www.cool.com teamor curse for more details welcome to my unboxing and first look at the Gigabyte HD 7790 this is a 2 gig card and it is an overclocked card with their windforce cooler now as you might imagine the 7790 exists somewhere between the 7770 and the 7850 it uses a very similar overall architecture to the rest of their gcn or a graphics core next architecture but it's basically just sort of everything that those cards are except a little less or a little bit more if that makes any sense to you guys it does support all the usual AMD Radeon features so direct X11 ifinity with up to four displays off of this particular card and then let's talk a little bit about gigabytes windforce cooler so their brand new windforce 2X is equipped with a new triangle cool design two 100 mm pwm fans an 8 mil heat pipe thicker heat pipes are better it's just so you guys know and the triangle cool integrates a patented triangle-shaped aluminum block into the aluminum Extrusion module which enhances the speed of heat dissipation more effectively so that's a block right there which basically just kind of moves the air um from going straight down to going through the fins at an angle which is actually sort of smart so let's see what they put inside this particular card is is overclocked from a standard 1 GHz to uh 1.75 gz so 1075 MHz comes with a quick start guide a Molex to PCI Express power adapter a driver disc which you should throw away some foam as well as a video card itself in an anti-static bag the anti-static bag is sealed by a piece of tape yay unboxings how we love them so there we go and the card itself is covered in a whole bunch of little protective coverings so check this out this is what they're talking about with their triangle thing so rather than just taking the airf flow that goes down directly through the F onto the PCB what they're effectively doing here is they're changing the direction a little bit although I have to wonder how much of it is being Chang oh yeah no a fair amount so the triangle piece goes all the way out to here and all the way out to about here so what that means is think about it this way guys if you have fins like this and air goes straight through them then the air passes over this much of the metal okay whereas if you have a fin like this and the air goes through this way then it gets to pass over this much of the metal effectively making the heat dissipation more efficient in theory this should also add a little bit of extra noise a little bit more turbulence but when you're using large uh slow rotating fans I suspect it's not going to be that much of an issue now this particular card see there you go more RAM on the back has the usual compliment of features I mean there's not really much that's Chang changed with 7790 that's probably why AMD opted not to go with an 8,000 series uh name for this particular card so it's still PCI Express 3.0 there's the connectors that I told you guys about which supports up to four displays so you've got your uh single analog output there remember guys DVID is not the same as DVI you can't do dual VGA off this card you've got HDMI as well as DisplayPort some external exhaust however due to the design of this cooler not a whole lot of heat is going to be coming off of there you've also got a cooler here for what must be some vrm components yeah it looks like they are it looks like um what gigabytes actually done is they've taken the 12vt power that comes in here routed it all the way across the card here where it'll be redistributed back this way because you can see this part of the PCB is actually quite bare and we've seen this a fair bit on recent cards where manufacturers are actually because they don't even need all this PCB space but they don't want the card to look like a little baby card they're just leaving a lot of blank PCB area so there you have it there's that 8 mil heat pipe that uh that I was talking about before you can see it's like you know pretty huge compared to there's a human pinky finger if nothing else and then a very solid block of aluminum makes up the rest of that cooler design so this is a relatively expensive cooler compared to what a reference design card would ship with so that heat pipe is carrying away from the solid block cooler over to the more uh thin fin type of Ray cooler where the second fan is doing most of its work a single PCI Express six pin power connector is provided and there is your Crossfire connector so the car does support two-way Crossfire but not three-way or moreway configurations thank you for checking out this unboxing of the HD 7790 wind force from Gigabyte don't forget to
