WEBVTT

00:00:07.759 --> 00:00:14.000
all right so you guys have asked me for this and I'm sorry okay I am going to

00:00:11.519 --> 00:00:17.960
make excuses because honestly I did not get a review sample card so I wasn't

00:00:15.879 --> 00:00:22.279
able to do that and then I had to go to CES so I wasn't able to do I Was

00:00:19.880 --> 00:00:26.800
preparing to go and then I was gone and then now I'm back and now I'm cat

00:00:24.160 --> 00:00:32.160
getting caught up so yes I am finally doing my unboxing of the radon hd7 970

00:00:30.840 --> 00:00:37.360
though you've probably seen somebody do a video about it already at this point

00:00:34.320 --> 00:00:41.239
and yes they were faster than me and yes

00:00:37.360 --> 00:00:43.879
that's okay um my ego is not too damaged

00:00:41.239 --> 00:00:50.120
by not being the first one to unbox this on the YouTube so here we go today's

00:00:48.520 --> 00:00:54.800
card is going to be from powercolor although honestly at the launch that's

00:00:52.440 --> 00:01:00.519
not terribly important because most partners are not going to have any kind

00:00:56.840 --> 00:01:02.719
of nonreference design cards XFX does

00:01:00.519 --> 00:01:07.000
have a card that is using a non-reference cooler however it is still

00:01:05.239 --> 00:01:11.080
using the reference PCB and reference components this is the way it works with

00:01:08.479 --> 00:01:15.119
all launch cards particularly on the highend for both AMD and NVIDIA so

00:01:13.640 --> 00:01:19.479
whatever you're about to look at inside this power color box is short of a

00:01:17.600 --> 00:01:24.400
couple accessories maybe a game bundle here or there pretty much exactly what

00:01:21.720 --> 00:01:29.000
you would find inside the box of one of powercolor competitors which is to say

00:01:27.479 --> 00:01:32.479
that powercolor given that their price is pretty good is proba probably a

00:01:30.520 --> 00:01:37.000
fairly good choice for a 7970 all right we have a driver disc

00:01:36.040 --> 00:01:41.560
which you shouldn't use you should download the latest we have professional

00:01:39.799 --> 00:01:45.200
cooling system oh no these are just this is just ads for like other power color

00:01:43.399 --> 00:01:49.840
stuff as well as a quick start guide we have a Dirt 3 code which you don't get

00:01:47.520 --> 00:01:55.920
to have because it belongs to whoever ends up with this card uh which might be

00:01:52.880 --> 00:01:55.920
me you never

00:01:56.000 --> 00:02:05.039
know I'm kind of liking the 7970 at this point in time this is a 28 nmet graphics

00:02:01.560 --> 00:02:06.680
card so or I shouldn't say it's a 28 nm

00:02:05.039 --> 00:02:12.840
graphics card cuz it's clearly a lot bigger than 28 nm but what it is is it

00:02:09.399 --> 00:02:14.560
is using a 28 nanometer GPU so that is

00:02:12.840 --> 00:02:18.920
the manufacturing process and I am going to finally

00:02:16.879 --> 00:02:22.959
extract these accessories there we go oh thank you for catching that um so what

00:02:21.000 --> 00:02:28.280
that means is basically lower power consumption than previous manufacturing

00:02:25.040 --> 00:02:31.879
processes so that means that AMD has the

00:02:28.280 --> 00:02:34.599
ability to squeeze 4.3 billion

00:02:31.879 --> 00:02:37.400
transistors into a space that previously they were not able to because you guys

00:02:35.879 --> 00:02:42.920
got to understand there's the overhead of R&D when you're producing chips and

00:02:40.000 --> 00:02:42.920
then other than

00:02:44.000 --> 00:02:50.840
that the actual cost of the Silicon wafer doesn't vary a whole lot from

00:02:49.159 --> 00:02:55.440
process node to process node I mean you can get slightly more expensive materials as you keep going but the

00:02:54.000 --> 00:02:59.840
whole idea is that if you can build more transistors in a smaller area the chip

00:02:57.239 --> 00:03:03.519
the whole thing actually costs less but if they take the other approach and they

00:03:01.159 --> 00:03:06.640
build just more transistors into the same area then it'll cost the same but

00:03:05.239 --> 00:03:12.280
it'll be more powerful and that's what we have with the radon 7970 so it

00:03:09.200 --> 00:03:14.920
supports up to four displays in ifinity

00:03:12.280 --> 00:03:19.720
mode so you've got your DVI your HDMI as well as dual

00:03:16.680 --> 00:03:21.959
mini DisplayPort there you go just

00:03:19.720 --> 00:03:26.640
going to put those plugs back in hate for hate for something to leak out of

00:03:25.080 --> 00:03:32.120
them or something although I don't think that's likely to happen with this particular graphics card um on the back

00:03:30.120 --> 00:03:36.599
you can see okay here here here let's just fine we'll just take them all off

00:03:33.799 --> 00:03:42.439
there all right what else is cool so 28 nmet GPU all right 384-bit memory bus so

00:03:40.400 --> 00:03:46.760
AMD has somehow managed to put all of the graphics memory on the other side of

00:03:44.319 --> 00:03:50.000
the PCB which is uh pretty pretty densely packed you can actually see

00:03:48.120 --> 00:03:55.840
where they are here and so what that means is huge massive memory bandwidth

00:03:52.879 --> 00:04:00.400
so we're still using gddr5 but we are able to write to it and read from it

00:03:57.959 --> 00:04:05.599
more quickly so enormous B with also an enormous frame buffer this card has a 3

00:04:03.159 --> 00:04:10.319
gbyte frame buffer now we've seen this before GTX 580 had a 3 gig frame buffer

00:04:08.680 --> 00:04:15.560
but honestly the GPU wasn't really powerful enough to take advantage of it

00:04:12.120 --> 00:04:18.840
anyhow GTX 590 had a 3 gig frame buffer

00:04:15.560 --> 00:04:21.639
so did Radeon 69 no 6990 was 4 gig sorry

00:04:18.840 --> 00:04:25.880
my bad so 590 had a 3 gig frame buffer but when you're running two gpus in SLI

00:04:24.080 --> 00:04:29.440
or Crossfire you're only able to take advantage of half of that frame buffer

00:04:28.199 --> 00:04:34.479
so if you were to take two of these three gig cards and run them in crossfire you would have three gigs of

00:04:33.080 --> 00:04:39.400
effective memory whereas if you took a GTX 590 and ran it in your system it's

00:04:37.800 --> 00:04:44.080
running an SLI by default you actually only have 1.5 gigs which is fine for

00:04:41.800 --> 00:04:47.680
single display up to huge resolutions but if you want to go multi-monitor

00:04:45.880 --> 00:04:51.840
gaming it's probably not going to be suitable in the latest games running at

00:04:49.720 --> 00:04:56.039
very high detail settings another new thing about this graphics card is it

00:04:53.240 --> 00:05:02.360
uses PCI Express 3.0 so what is the relevance of that you might ask and the

00:04:58.080 --> 00:05:04.440
relevance of that I would answer is um

00:05:02.360 --> 00:05:10.680
very little I'm actually wandering around now looking to see if I can find

00:05:07.320 --> 00:05:11.880
a gen 3 motherboard ah you know what

00:05:10.680 --> 00:05:15.759
don't worry about it okay so there's a couple motherboards on the z68 platform

00:05:14.440 --> 00:05:22.680
I'm going to walk around this way let's let's go look at the card I guess for now there's a couple motherboards on the

00:05:18.880 --> 00:05:26.160
z68 platform that are using uh

00:05:22.680 --> 00:05:28.000
PCIe gen 3 compatible slots but right

00:05:26.160 --> 00:05:33.160
now it doesn't even work because ivybridge Intel's upcoming C puu which

00:05:30.199 --> 00:05:36.479
will have p a PCIe gen 3 controller on board isn't even out yet so we're

00:05:35.360 --> 00:05:43.680
basically these motherboards are just saying they're ready for you to drop in a new CPU and a new graphics card to get

00:05:40.400 --> 00:05:45.720
gen 3 compatibility so there's that and

00:05:43.680 --> 00:05:51.800
there's also the fact that PCI Express 16x like gen one like PCI Express 16x is

00:05:49.360 --> 00:05:56.639
still plenty for a single graphics card so what does this mean to you well every

00:05:54.680 --> 00:06:00.639
time we go up a generation in PCI Express we are doubling the available

00:05:58.280 --> 00:06:07.759
bandwidth so PCI E2 is two times the bandwidth of PCIe 1 and PCIe Gen 3 is

00:06:04.039 --> 00:06:11.039
four times the bandwidth of PCIe gen 1

00:06:07.759 --> 00:06:13.400
what that means is that a PCIe Gen 2 adx

00:06:11.039 --> 00:06:17.599
slot which is what we find on z68 boards is already capable of feeding a high-end

00:06:16.160 --> 00:06:21.639
graphics card pretty much no matter high end it no matter how high-end it is so

00:06:19.840 --> 00:06:25.280
with PCIe Gen 3 we're going to get the ability to run high-end graphics cards

00:06:23.240 --> 00:06:29.560
in our PCIe 4X slots that looks to be about it so we

00:06:28.280 --> 00:06:33.800
may actually be able to run like threeway SLI and Crossfire setups on

00:06:31.840 --> 00:06:38.880
like you know four four four4 slot layouts and not have any performance

00:06:35.520 --> 00:06:40.400
hits so I guess that's cool but um I

00:06:38.880 --> 00:06:44.560
mean motherboards already have so many PCIe slots with so much bandwidth I'm

00:06:42.960 --> 00:06:49.039
not that concerned about it just right now so there you go PCI E gen 3 so yes

00:06:47.120 --> 00:06:51.400
more bandwidth is probably better at some point but right now I don't think

00:06:50.479 --> 00:06:56.639
it's going to make that much of a difference it has a sticker on

00:06:53.560 --> 00:07:00.319
it the radon H

00:06:56.639 --> 00:07:01.960
7970 huh funny okay uh it has

00:07:00.319 --> 00:07:05.560
what we've come to expect is a standard AMD blower cooler fan which is great

00:07:04.000 --> 00:07:08.520
because it means it's exhausting all of the air out the back of the case so

00:07:07.440 --> 00:07:13.000
you're not going to have this thing reheating itself although it runs

00:07:10.919 --> 00:07:18.360
surprisingly quiet and cool considering that this is barnone by a significant

00:07:15.639 --> 00:07:23.919
margin the fastest single GPU graphics card on the planet so yes it does lose

00:07:20.120 --> 00:07:26.680
to the 590 it does lose to the 6990 but

00:07:23.919 --> 00:07:32.240
it is faster than a GTX 580 which was the previous King of the cast

00:07:30.039 --> 00:07:35.840
and it also overclocks like a beast speaking of overclocking you've got two

00:07:33.720 --> 00:07:39.039
BIOS profiles here so you can keep one at factory default you can Flash

00:07:37.479 --> 00:07:44.080
alternate bioses to the other one and play around with it and see how far you

00:07:41.479 --> 00:07:48.360
can push this card AMD has built in that mod ability to their cards which hold on

00:07:46.599 --> 00:07:54.280
let me just put this down which is awesome so I personally

00:07:51.280 --> 00:07:55.879
appreciate that very very much I think

00:07:54.280 --> 00:07:59.759
we've pretty much wrapped up here I don't think I see anything on my notes

00:07:57.680 --> 00:08:03.680
over there that looks IR relevant so thank you for checking out my unboxing

00:08:02.159 --> 00:08:09.479
and uh by this time it's probably about your 18th look at the radon H 7970 don't

00:08:07.960 --> 00:08:13.400
forget to subscribe to lus Tech tips from unboxings reviews and other

00:08:11.000 --> 00:08:16.960
computer videos I'm clearly out of practice because I forgot to show you it

00:08:15.159 --> 00:08:21.199
has an 8 pin and a six pin power connector and I also forgot to show you

00:08:18.919 --> 00:08:27.400
the included accessories so it does have HDMI to DVI mini DisplayPort two

00:08:24.319 --> 00:08:30.159
DisplayPort mini DisplayPort to is

00:08:27.400 --> 00:08:35.039
this active oh active DVI cool so it does support dual DVI right out of the

00:08:32.479 --> 00:08:39.000
box triple DVI right out of the box wow you have everything you need to run

00:08:36.039 --> 00:08:43.760
ifinity right out of the box and then a six pin to 8 Pin power adapter a DVI to

00:08:41.240 --> 00:08:46.760
VGA adapter and finally a crossfire connector
