WEBVTT 00:00:07.439 --> 00:00:13.160 better late than never that's what I say and I hope you guys agree this will be 00:00:11.320 --> 00:00:18.480 my oh I don't know where my knife is there it is this will be my unboxing and 00:00:15.559 --> 00:00:22.880 first look at the Radeon hd7950 from Sapphire now there's 00:00:20.800 --> 00:00:28.320 something a little bit special about this particular hd7950 from Sapphire and 00:00:26.480 --> 00:00:32.960 that is that in addition to being a non-reference design 00:00:31.279 --> 00:00:36.920 so that is to say it comes on a non-reference PCB which we've come to 00:00:35.040 --> 00:00:41.960 expect from 7950 it also has a non-reference cooler and it is overclock 00:00:39.680 --> 00:00:46.640 so it's a 3 gig card has support for their tricks uh tweak and overclock 00:00:44.480 --> 00:00:50.520 utility for Sapphire graphics cards it comes with an HDMI cable okay so this is 00:00:48.719 --> 00:00:53.199 all very interesting there's a lot of stuff here but we're going to cover most 00:00:51.800 --> 00:01:00.480 of this when we get a little bit further in so much like the radon HD ah here we 00:00:56.719 --> 00:01:06.280 go 7970 so this is an oem card with the 00:01:00.480 --> 00:01:08.960 completely um yeah dull as anything uh 00:01:06.280 --> 00:01:16.960 reference cooler reference PCB so unlike similarly to the 7970 it uses the 00:01:12.520 --> 00:01:19.000 Tahiti core so that is a 28 nmet GPU and 00:01:16.960 --> 00:01:24.159 the difference is that it has slightly fewer functional units than the 7970 and 00:01:22.000 --> 00:01:28.040 in its default configuration anyway it is clocked a little bit lower both of 00:01:26.079 --> 00:01:32.680 these graphics cards have 3 gigs of memory and they're using the latest 28 00:01:30.439 --> 00:01:40.079 nanom manufacturing process in order to achieve outstanding performance with 00:01:36.759 --> 00:01:42.759 really what is um was previously thought 00:01:40.079 --> 00:01:46.719 to be completely unbelievable power consumption not unbelievable in a bad 00:01:45.119 --> 00:01:50.320 way unbelievable in a good way we're not talking like you know GTX 480 here we're 00:01:49.320 --> 00:01:55.600 talking like seems like it could be like a 2600 00:01:53.880 --> 00:02:00.159 Pro in terms of the power consumption at Idol but it is actually a full-fledged 00:01:57.759 --> 00:02:06.119 gaming card so Inside the Box we find the driver installation disc we find a 00:02:02.759 --> 00:02:08.280 quick installation guide we find a 00:02:06.119 --> 00:02:14.440 product registration card probably a good idea to use that okay Crossfire 00:02:12.080 --> 00:02:19.599 Bridge lots of wow look at all this stuff comes with lots of stuff so we've 00:02:16.879 --> 00:02:27.200 got two eight pin two oh no we have a two Molex two PCIe six pin 00:02:23.720 --> 00:02:29.440 adapters there's the 1.8 m HDMI cable 00:02:27.200 --> 00:02:33.519 that they claimed was included and I have now validated that it is actually 00:02:31.200 --> 00:02:40.840 included we also get a mini DisplayPort to DisplayPort adapter a HDMI to DVI 00:02:38.920 --> 00:02:47.400 adapter although it should be noted that this will only work for single link DVI 00:02:43.400 --> 00:02:49.319 so that is up to 1920 x 1200 at 60 HZ 00:02:47.400 --> 00:02:54.000 because you are still relying on the HDMI port which is only single link 00:02:51.319 --> 00:02:58.920 we've also got a DVI to VGA adapter so we can go ahead and throw all these back 00:02:56.000 --> 00:03:01.840 in here and let's have a look at the card itself 00:03:01.879 --> 00:03:06.959 so yes I have all these other cards over here and I'm definitely I'm definitely 00:03:05.599 --> 00:03:12.200 getting to that that's going to be more of a more of a size comparison thing 00:03:09.360 --> 00:03:17.159 than anything else there we go wow that's actually a gorgeous looking card 00:03:14.480 --> 00:03:24.400 so here we have it the sapphire hd7950 it has dual 92mm cooling fans on 00:03:21.400 --> 00:03:27.280 a very very robust looking cooler so 00:03:24.400 --> 00:03:31.680 check this out we've got dual thick heat pipes and then triple thinner heat pipes 00:03:29.799 --> 00:03:35.400 P all of them are taking heat away from the GPU core itself which you can 00:03:33.200 --> 00:03:41.439 actually see right there from the GPU core itself as far away as possible uh 00:03:38.920 --> 00:03:45.000 to the aluminum fins that are cooling it so what you'll notice is that they use 00:03:42.959 --> 00:03:49.120 the thicker heat pipes for the greater distances in order to make sure that 00:03:46.760 --> 00:03:53.640 we're carrying heat effectively away even over here so that this fan actually 00:03:51.640 --> 00:03:59.079 has heat to carry away from the metal in order to cool the GPU itself it uses a 00:03:56.680 --> 00:04:01.720 very very open design so you can see as I turn it around 00:04:02.239 --> 00:04:11.480 the Fan's air flow is not impeded pretty much in any way by a shroud or any other 00:04:09.159 --> 00:04:16.519 characteristics of the cooler itself so it's got a plastic shroud right here and 00:04:13.599 --> 00:04:21.359 then it's see that free air flow coming from the fans down out around the GPU 00:04:19.199 --> 00:04:25.160 what this means is a couple of things so one it means that heat is being expelled 00:04:23.639 --> 00:04:31.479 into your case so if you don't have a decent case that you know has intake 00:04:29.160 --> 00:04:35.960 fans and exhaust fans if you're using like a crummy sort of mini tower or 00:04:33.800 --> 00:04:40.639 something like that you might not prefer a card like this you might prefer one 00:04:38.080 --> 00:04:45.919 that sticks with a more reference design which is an external exhaust blower fan 00:04:43.639 --> 00:04:50.360 like that however if you do have a decent case these are usually much more 00:04:48.560 --> 00:04:56.000 effective than those reference coolers at removing heat from the GPU the memory 00:04:52.320 --> 00:04:59.479 and the vrm and at the cost that you do 00:04:56.000 --> 00:05:02.199 expel some of the heat into your case so 00:04:59.479 --> 00:05:05.160 yeah yeah something to consider uh what actually speaking of vrm what are we 00:05:03.520 --> 00:05:09.400 doing for vrm cooling oh this is kind of smart check this out so they've got the 00:05:07.400 --> 00:05:12.520 the usual sort of GPU cooling thing going on here but then they've also 00:05:10.759 --> 00:05:17.440 added a heat spreader so you see this black piece right here that goes pretty 00:05:15.039 --> 00:05:21.680 much all the way around and wraps up here around the top so that's covering 00:05:19.280 --> 00:05:26.120 up all the memory modules all three gigs of memory are actually located you can 00:05:23.840 --> 00:05:30.880 see the positions of them are located on this side of the PCB uh some of the 00:05:28.880 --> 00:05:35.680 other vrm components are not covered by a heat sink but they do have direct air 00:05:33.160 --> 00:05:39.520 flow from a fan coming down on them from the top so I right I was saying 00:05:38.080 --> 00:05:43.400 advantages and drawbacks of these coolers right so they tend to be cooler 00:05:41.560 --> 00:05:47.280 and quieter than reference coolers but the drawback is that they do exhaust the 00:05:45.080 --> 00:05:53.440 heat into your case so just make sure you got a decent case or like me no 00:05:50.280 --> 00:05:54.919 case that is another solution okay so 00:05:53.440 --> 00:05:58.960 what other characteristics here so you saw the two included MOX to six pin PCIe 00:05:57.360 --> 00:06:03.440 adapters that's because this card requires two two PCI Express six pin 00:06:01.280 --> 00:06:07.199 adapters you can see on it actually this is kind of interesting yeah so this is a 00:06:05.520 --> 00:06:12.479 completely non-reference card okay you can see on it that there was room for an 00:06:09.319 --> 00:06:14.639 a pin adapter here but they did not deem 00:06:12.479 --> 00:06:20.360 that to be necessary remember the Tahiti Pro so that's the 7950 does not require 00:06:17.759 --> 00:06:23.479 as much power as the 7970 in terms of output options these are very similar to 00:06:22.199 --> 00:06:29.599 what we're used to seeing on these cards it does support up to four display 00:06:26.120 --> 00:06:33.599 ifinity so that is DVI HDMI and two Mini 00:06:29.599 --> 00:06:35.479 display ports right here and on the back 00:06:33.599 --> 00:06:41.000 I guess there's not much else to say about it now why do I have all these 00:06:38.080 --> 00:06:46.319 cards here right let's get to that this is an overclocked card so what I want to 00:06:44.120 --> 00:06:50.599 find out because I've never actually taken a look at a not overclocked 00:06:48.840 --> 00:06:55.720 actually this is more like this yeah there we go I've never actually taken a 00:06:53.000 --> 00:07:00.879 look at a non overclocked 7950 so one of the things I tried to do tonight was 00:06:57.479 --> 00:07:03.280 flash my 7970 reference card with a 7950 00:07:00.879 --> 00:07:06.800 BIOS to see if I could actually turn off some of the shaders so that I could 00:07:05.000 --> 00:07:12.160 compare this against like a fully referenced 7950 uh but I'm not able to do that 00:07:10.639 --> 00:07:16.960 unfortunately it just turns down the clock speed it doesn't turn down the shaders so what I'm going to be doing is 00:07:15.080 --> 00:07:21.360 I'm going to be taking this overclocked version of the card and I'm going to see 00:07:18.840 --> 00:07:25.840 how it Compares against a itself at stock clock speed so I'll just turn dial 00:07:23.560 --> 00:07:29.520 them back to reference clocks using the uh the included uh overclocking utility 00:07:28.240 --> 00:07:33.599 which can also be used for underclock focking and then I also want to compare 00:07:31.280 --> 00:07:42.199 it against a wide variety of other cards so here I have a 6990 GTX 590 I have a 00:07:38.280 --> 00:07:44.720 7970 GTX 580 I have the 7950 which will 00:07:42.199 --> 00:07:49.720 be OC and not OC but it'll be the same card I'm just going to change the clock 00:07:46.080 --> 00:07:53.639 speeds I have a GTX 570 and I have a 00:07:49.720 --> 00:07:55.400 6970 6950 so I use the BIOS uh switch in 00:07:53.639 --> 00:07:59.840 order to switch this card between those two different bioses because this one 00:07:57.599 --> 00:08:04.319 can be locked and unlocked so stay tuned online as Tech tips for a closer look at 00:08:02.400 --> 00:08:07.639 this card we're also going to profile the overall noise and heat 00:08:05.720 --> 00:08:10.639 characteristics of it and thank you for
