00:00:07.560 --> 00:00:13.480
welcome to my unboxing of something that's actually fairly exciting this is

00:00:11.880 --> 00:00:18.240
the Radeon hd7950 this is a bit of a step down from

00:00:17.439 --> 00:00:23.680
the 7970 but they haven't actually reduced

00:00:21.279 --> 00:00:30.800
the performance that much so today not only do I have a Radeon hd7950 to unbox

00:00:27.400 --> 00:00:34.320
and take a bit of a look at but I have a

00:00:30.800 --> 00:00:38.879
particularly special one so this is the

00:00:34.320 --> 00:00:41.520
XFX Double D and uh that is not to say

00:00:38.879 --> 00:00:48.760
that it goes here necessarily but rather to say that it is double dissipation so

00:00:45.399 --> 00:00:51.960
that means they've put um hold

00:00:48.760 --> 00:00:55.239
on an aftermarket cooler on what is

00:00:51.960 --> 00:00:57.559
otherwise still a reference 7950 so you

00:00:55.239 --> 00:01:02.719
can rest assured that you're getting the quality that goes along with a reference

00:01:00.079 --> 00:01:08.720
board or whatever else but you are also getting two fans for removing heat from

00:01:05.960 --> 00:01:12.119
your card so what does XS have to say about it let's go with that first and

00:01:10.200 --> 00:01:16.600
then we'll open up the card itself so it has 3 gigs of memory for Max effect and

00:01:15.040 --> 00:01:20.280
resolutions I'm sure they mean effects and resolutions um but yeah basically

00:01:19.320 --> 00:01:24.680
what that means is that if you're running even three monitors in ifinity

00:01:22.880 --> 00:01:30.200
mode you're going to have enough of a frame buffer in order to not suffer from

00:01:27.600 --> 00:01:34.479
a serious performance leg that results when the graphics memory fills up and

00:01:32.200 --> 00:01:38.520
you have to go to your hard drive which is slow or even system memory or

00:01:36.840 --> 00:01:42.360
anywhere else it's slower than Graphics memory Next Generation performance they

00:01:40.680 --> 00:01:47.399
are very correct about that even though this is not a topof the range card it

00:01:44.719 --> 00:01:52.560
does perform as well or better than NVIDIA's premium GTX 580 ghost thermal

00:01:51.119 --> 00:01:57.000
maximizes air flow for exceptional venting throughout the card that's interesting we'll have to have a look at

00:01:55.119 --> 00:02:00.560
that what else we got here multim monitor difference yep okay so it does

00:01:59.079 --> 00:02:05.960
support Infinity up to four monitors unique dual

00:02:03.600 --> 00:02:10.399
fan design allows air to cool everything including including

00:02:08.000 --> 00:02:15.319
thermal including GPU heat sncs components in the PCB board so that I'll

00:02:12.360 --> 00:02:18.760
believe okay what else we got here oh five star support register your product

00:02:17.080 --> 00:02:23.319
and get industry leading festar support yeah make sure you

00:02:20.160 --> 00:02:26.360
register okay gen Ultra bandwidth kpci

00:02:23.319 --> 00:02:28.720
3.0 yes it does have PCI 3.0 so we'll

00:02:26.360 --> 00:02:34.640
talk about that a little bit more after okay tessellation

00:02:31.239 --> 00:02:36.080
bullet physics engine resident textures

00:02:34.640 --> 00:02:42.800
okay these are probably kind of extreme examples but basically more better than

00:02:39.760 --> 00:02:44.120
before hydrocell thermal solution

00:02:42.800 --> 00:02:50.200
interesting condensation Wicks evaporation Wicks okay so they're talking about uh

00:02:48.280 --> 00:02:55.720
basically uh what are they called again Vapor Chambers yep superial thermal

00:02:52.480 --> 00:02:59.280
perfect for overclocking okay cool let's

00:02:55.720 --> 00:03:00.800
get it opened up first we have a little

00:02:59.280 --> 00:03:05.440
brochure for their Pro Series power supplies other great XFX products

00:03:02.599 --> 00:03:09.840
including adapters Hardware limited warranty let's have a look at oh okay so

00:03:08.319 --> 00:03:16.760
they want you to go and check it out on XFX force.com quick install guide driver

00:03:13.440 --> 00:03:18.000
CD install guide okay and there's the

00:03:16.760 --> 00:03:25.879
driver CD next we've got uh a crossfire Bridge

00:03:22.239 --> 00:03:27.480
as well as an HDMI 2 DVI adapter that's

00:03:25.879 --> 00:03:32.840
an interesting one you don't see that included with video cards very often

00:03:29.799 --> 00:03:35.080
we've also got one of XFX is trademark

00:03:32.840 --> 00:03:39.200
uh door hangers I've actually got one in the in this room over here check it out

00:03:37.640 --> 00:03:43.239
this is an older one this is from back when XFX did uh NVIDIA graphics cards

00:03:41.959 --> 00:03:47.519
but there see now I have another one to go with it pretty cool and these are

00:03:45.439 --> 00:03:52.079
handy because they also keep your serial number and all that cool information on

00:03:50.000 --> 00:03:56.280
the back of it so that means that you can

00:03:53.720 --> 00:04:01.760
uh not have to pull the card out of your system if you ever need to look anything

00:03:58.760 --> 00:04:03.959
up on the xfs XFX website or register it

00:04:01.760 --> 00:04:09.720
or whatever else so let's open up the double dissipation

00:04:06.120 --> 00:04:14.280
7950 and have a look at it so these are

00:04:09.720 --> 00:04:18.759
two are these 90 mil fans hold on a sec

00:04:14.280 --> 00:04:21.600
sorry so yes that is two 90 92 mil fans

00:04:18.759 --> 00:04:26.400
uh over a huge wow look at this oh this is interesting so this is what they mean

00:04:23.000 --> 00:04:27.680
by this over a huge heat sink array so

00:04:26.400 --> 00:04:31.160
you can see the heat sink goes all the way from here down to here it's got a

00:04:29.400 --> 00:04:35.759
bit of a stepped appearance going on so that means it can benefit not only from

00:04:33.360 --> 00:04:39.919
the air that is blowing directly down onto the PCB but also some of that

00:04:38.160 --> 00:04:43.560
incidental air flow that comes from around the edge of the spinning fan so

00:04:42.000 --> 00:04:47.240
you can see they built up the heat sink in these areas in order to take

00:04:45.800 --> 00:04:53.320
advantage of that you can see we've got a sleeved connector here that provides

00:04:49.600 --> 00:04:55.479
power for one two fans um and then you

00:04:53.320 --> 00:04:59.160
can see what they mean this is their this is their interesting cooler design

00:04:57.120 --> 00:05:05.240
here so they've actually left it quite open around the bottom of the card so

00:05:01.240 --> 00:05:06.520
here's our PCI Express 3.0 16x slot and

00:05:05.240 --> 00:05:12.520
what that means is that some of the incidental air flow from these fans is going to cool not only the graphics card

00:05:10.280 --> 00:05:17.080
itself but also your motherboard below it now with some last generation

00:05:15.000 --> 00:05:21.520
products from both the AMD and the NVIDIA side a design like this wasn't

00:05:19.600 --> 00:05:25.639
really an option because they needed all the airf flow possible from these fans

00:05:23.960 --> 00:05:30.120
in order to keep the graphics card cool enough but the 7950 is actually

00:05:27.720 --> 00:05:34.759
significantly cooler running and more efficient than some of these last

00:05:31.639 --> 00:05:37.240
generation products due to the improved

00:05:34.759 --> 00:05:40.360
manufacturing process so we're able to take advantage of some of this air flow

00:05:38.800 --> 00:05:44.680
and use it to cool the rest of your system and ensure that not only does

00:05:42.960 --> 00:05:49.440
your graphics card run stable but so does your entire PC on the back you can

00:05:47.160 --> 00:05:54.759
see the other the uh the end of this aluminum shroud goes right here on the

00:05:52.720 --> 00:05:58.520
top this is a very nice touch check this out so not only you can see it's quite

00:05:56.919 --> 00:06:03.520
open you can see those fan blades in there see me spinning them so that same

00:06:00.919 --> 00:06:08.039
that same kind of uh thinking although I don't see how it's nearly as beneficial

00:06:05.479 --> 00:06:12.560
here but I guess what it does is it also provides less restriction for the fans

00:06:10.039 --> 00:06:18.160
overall so not only can you exhaust air out the back of the card uh not so much

00:06:15.080 --> 00:06:20.360
out this side but out here you can also

00:06:18.160 --> 00:06:24.319
exhaust all the air from your fans all around the card which means that they're

00:06:21.840 --> 00:06:28.880
not going to be very restricted but XFX has included instead of a plastic accent

00:06:26.560 --> 00:06:32.520
here they've included an aluminum accent it's got kind of a brushed finish to it

00:06:31.000 --> 00:06:38.000
just like the rest of the cooler that looks very very sharp it's branded with

00:06:35.240 --> 00:06:42.680
their ghost thermal technology bit here as well as their XFX r7950 thing that's

00:06:41.120 --> 00:06:46.800
going on here the good news about this entire cooler is that none of the

00:06:44.759 --> 00:06:53.160
numbers can fall off like I had happened during my 7970 unboxing

00:06:50.280 --> 00:06:57.680
video now let's have a look at the back of this card this is not a reference

00:06:55.520 --> 00:07:01.080
board so I was mistaken this is an aftermarket cooler on an aftermarket

00:06:59.680 --> 00:07:07.560
board it looks like they're probably using the reference design but this is

00:07:03.680 --> 00:07:11.080
clearly an XFX style matte black PCB so

00:07:07.560 --> 00:07:12.639
there you go guys um I stand corrected

00:07:11.080 --> 00:07:17.240
on that you can see all of the memory chips are installed on the other side of

00:07:14.960 --> 00:07:21.759
the PCB so that's 3 gigs of RAM over there our vrms are here our power is

00:07:19.879 --> 00:07:26.039
here you can see there are pin outs for a six pin and an 8 Pin but the card

00:07:24.360 --> 00:07:31.479
itself due to its lower power requirements compared to the 7970 only

00:07:28.599 --> 00:07:35.599
uses dual 6 pins we've got two Crossfire connectors so that is for well

00:07:34.039 --> 00:07:42.039
connecting to other cards to run in crossfire I've already talked about the

00:07:37.560 --> 00:07:43.560
PCI Express 3.0 so that is Gen 3 PCIe

00:07:42.039 --> 00:07:47.560
connector on the bottom but what I should also mention is that it is fully

00:07:45.240 --> 00:07:52.520
backwards compatible with a PCI Express Gen 2 or even PCI Express gen 1

00:07:50.960 --> 00:07:57.639
motherboard so don't worry about that although if you go all the way back to a gen one board you're probably going to

00:07:55.680 --> 00:08:03.000
be bottlenecking this graphics card with the interface itself however

00:08:00.240 --> 00:08:08.000
this graphics card is still by I mean when it's saturating a PCIe gen 1

00:08:05.720 --> 00:08:11.720
interface is still going to be more than any CPU that runs on that motherboard is

00:08:10.080 --> 00:08:16.479
going to be able to keep up with anyway so the bottleneck will still exist on

00:08:13.280 --> 00:08:18.360
the CPU side not with the PCI Express

00:08:16.479 --> 00:08:21.720
interface so now let's go ahead and have a look at what we've got for inputs and

00:08:19.759 --> 00:08:26.080
outputs oh I see why we have an HDMI to DVI adapter it's so that we can easily

00:08:24.000 --> 00:08:30.000
run dual DVI since most people running two displays are using that and then

00:08:28.080 --> 00:08:36.719
with four displays you can go either DVI HDMI mini DisplayPort mini DisplayPort

00:08:32.560 --> 00:08:39.320
or DVI DVI via adapter mini DisplayPort

00:08:36.719 --> 00:08:45.160
mini DisplayPort we've got a little XFX branded exhaust slot going on there and

00:08:42.479 --> 00:08:50.360
I think that pretty much covers it so what is the benefit of the 7950 well the

00:08:47.320 --> 00:08:52.800
7950 is cheaper than the 7970 we covered

00:08:50.360 --> 00:08:57.839
that already overclocks like a beast even though the reference stock clock

00:08:55.200 --> 00:09:03.560
speed is only 800 mahz these cards have been seen already going up around the

00:09:00.079 --> 00:09:06.720
1,000 MHz or 1 GHz Mark so what that

00:09:03.560 --> 00:09:08.959
means is we're looking at 20 to 25%

00:09:06.720 --> 00:09:14.240
overclocks on an Enthusiast level graphics card which hasn't been seen in

00:09:10.839 --> 00:09:15.880
a fair while so I guess not only did AMD

00:09:14.240 --> 00:09:20.360
achieve better thermal performance and better power consumption with their new

00:09:18.240 --> 00:09:23.760
manufacturing process but also better overclocking headro so thank you for

00:09:22.240 --> 00:09:28.760
