0:07 Welcome to my unboxing and first look at something that's very exciting. This is
0:11 the Galaxy GeForce GTX 670. It supports
0:15 a wide variety of exciting features, most of which you can actually find out
0:20 about on my Galaxy GTX 680 unboxing as
0:23 well as review and all the other videos I did about it. because the 670 is
0:27 actually very similar to the 680 in many ways. Now, sure, it doesn't have quite
0:33 as many CUDA cores. It only has 1,344.
0:38 Sure, it's not clocked quite as high with a boost clock that's generally in
0:41 the neighborhood of around 980 MHz, although GPU boost doesn't necessarily,
0:46 you know, nail it down to an exact frequency at any given time. And
0:53 sure, it might look a little different, and more on that in a moment, but in
0:56 terms of the performance, in terms of the memory speed, in terms of the memory
1:01 bus, this is the first time in a while we haven't seen a a step down card from
1:06 the flagship single GPU that is actually using the same memory bus at the same
1:11 frequency. So, it has six gigahertz DDDR5 memory with a 256 bit bus. Um,
1:18 it's using the Right, right, right. So, the reason that most of the features are
1:22 very similar is because it is using the same GK 104 core that the GTX 680 is
1:27 using, although slightly cut down in terms of the functional units, the CUDA
1:31 cores and the clock speed. But other than that, this is almost a GTX 680,
1:37 although the key difference is that it comes at a more attractive price. So,
1:42 you can see it actually looks very similar as well. More on that in a
1:46 moment. So, let's just have a look at what Galaxy includes with their GTX 670.
1:51 In here, we find slick all black packaging. I'm a big fan of packaging,
1:54 as you guys probably know, if you've watched a few of my videos. I unpackage
1:58 a lot of products, so I do recognize good packaging when I see it. Got nice
2:02 little individually packaged zip locky things going on here. So, we got a DVI
2:06 to VGA adapter. We have uh two dual
2:11 Molex to six pin PCIe adapters. So that probably tells us that this card uses
2:15 dual six pin PCIe power adapters as well as a graphics card driver installation
2:19 disc. Although you should download the latest and finally a setup guide, easy
2:23 setup for quick installation for GeForce GTX 600 series pamphlet and
2:29 then a user's manual. So that pretty much covers it. Attention customers,
2:32 thank you for purchasing your blah blah blah. Be sure to register your card within 30 days of purchase to receive an
2:37 extended warranty. So Galaxy does provide up to I believe it's three
2:42 years. Yes, 3 years of warranty if you extend if you uh register your card
2:47 right away. So, let's go ahead and I
2:51 don't know how this works. So, I'll figure that out later.
2:55 Now, let's get to the card itself. So, first let's do a brief rundown. And
2:59 yeah, I'm totally going to look over there and use my cheat sheet because that's how I roll of the features that
3:03 the GTX 670 includes that were first introduced on the 680. So we've got uh
3:09 GPU boost which means that it dynamically according to the TDP that is
3:13 the thermal design envelope of this particular card as well as the power
3:17 envelope is going to adjust assuming that your GPU is running cool enough and
3:22 your board is not consuming too much power like if you're using something
3:26 like Firmark then it would know that well that's not a real game and it's
3:29 drawing more power than is realistic. GPU boost will dynamically adjust the
3:34 frequency of your GPU in order to make the best use of the power and the heat
3:40 envelope that it has available to it. So GPU boost is definitely present on the
3:44 670. We also have FXA has been added to
3:47 the NVIDIA control panel, although that's accessible to for many different cards. Now adaptive VSYNC is one that's
3:53 really cool. So, adaptive VSYNC allows you to either be using VSYNC when your
3:59 frame rate is way way above the refresh rate of your monitor, whether it's 60 or
4:03 120 or whatever the case may be. So, it will turn VSYNC on to eliminate tearing.
4:07 So, that is when your GPU draws the top
4:10 half of the screen and the bottom half of the screen in the middle of a monitor
4:14 refresh and you see like there's a guy standing there and he's like slightly
4:17 disconnected at the waist. So, that's tearing. So the VSIC will turn on when
4:21 you're up there and then when you are below 60, let's say 60 for our
4:25 hypothetical in most monitors, most LCDs are 60 Hz. When you're below 60 Hz, it
4:30 will no longer have to drop you all the way down to 30 if your GPU is capable of
4:35 pushing 55 frames per second, which is how VSYNC works. So it turns VSync off
4:40 as soon as you fall below that threshold. So you get the best of both worlds. So that's adaptive VSYNC. TXA is
4:46 uh basically more
4:50 What do they what do they what do they sort of call it pretty much um the
4:54 performance of yeah see I'm mode one
4:57 right two times
5:01 multi-sampling AA performance and it looks like eight times AA so that's
5:05 basically that and then mode two is you
5:08 know what hold on give me a sec I couldn't read my little chart from too
5:12 far away so mode one is the performance hit of two times anti-aliasing and it
5:16 looks about like eight times anti-aliasing And then mode two looks
5:19 even better than that and is about the same performance hit as four times
5:22 anti-aliasing. So that is also present on this card. Next, we have full support
5:27 for NVIDIA 3D vision surround off of a
5:30 single card. So you can go one, two, three displays with an auxiliary
5:34 display. No big deal. So you want to run your three displays and then your
5:39 auxiliary one can't run the game at the same time. It's not for surround gaming.
5:42 But if you had like, you know, a chat window open or like system monitoring
5:47 utilities or stuff open on that fourth monitor, then you can totally run that
5:50 one as well. So up to 3 + 1 displays is
5:53 also supported on this card. 4K monitor support as well as HDMI 1.4A that
5:58 includes 3D, which is very, very cool stuff. Better Physics performance. And
6:04 we're pretty much there. Now, let's have a look at the card itself. So, it uses a
6:08 similar blower design cooler, which also includes the acoustic dampening um
6:13 hoo-ha that NVIDIA included with the GTX 680. You can see it's a slightly shorter
6:17 card, although it's more than slightly shorter, which I'll show you more of in a moment. Uses the same fan, which is
6:22 good because the GTX 680 fan is excellent. It is a PCI Express 3.0 card,
6:27 which is good if you have the latest IV Bridge platform for your system. You can
6:31 see on the back we got sort of, you know, more like plasticky shroudy thing.
6:34 There's our PCIe interface. I already showed you the two DVI HDMI and display
6:38 port connectors. Up here we've got cool GeForce GTX branding. And then here
6:43 we've got our two six pin PCIe connectors. And what you may have
6:46 noticed about that is it's in kind of a weird location. Why would that be?
6:51 Because the GTX 670 comes with a very
6:56 short PCB. NVIDIA has actually rotated the GPU around to make better use of the
7:01 power circuitry being on the uh the back
7:05 half of the card. So all your power delivery is actually here instead of
7:09 here. So they no longer needed that segment of the PCB. Check this out.
7:14 There you go. So you can see this 670 is a reference 670 and there's actually
7:18 extra room for more graphics memory. So you can buy a 670 with up to 4 gigs of
7:23 graphics memory. And where all that power delivery circuitry normally is,
7:26 it's no longer there. So, they are still using the nice long efficient blower
7:31 cooler, which is going to exhaust most of the air out the back of your case. And you can also see there's a nice big
7:36 gap between the heat sink and these uh these vents back here, which actually
7:40 allows for slightly better air flow. But
7:43 they've used a very very efficient design to achieve that. Speaking of
7:47 efficiency, it is um by far better
7:50 performance per watt than anything else that NVIDIA has produced in this kind of
7:54 a price range before. So, it's uh like I said using the same GPU as the GTX 680,
8:00 which means it just blows away its predecessors, the 570, the 470 in terms
8:05 of the performance per watt that this card can deliver. It is compatible with
8:09 multi-way SLI configurations due to its two SLI uh its two SLI bridge.
8:15 two SLI connectors. Sorry guys, I'm tired. And I think that pretty much
8:20 covers it. So, thank you for checking out my unboxing and first look at the
8:24 GeForce GTX 570 from Galaxy. And don't forget to subscribe to Lest Tech Tips
