3D Vision one of NVIDIA's Marquee technology so to go along with the
GeForce GTX 680 launch here I've got my
Galaxy GeForce GTX 680 I can remove the glasses so you guys can see what the
card looks like if you haven't already seen my regular performance review or my
unboxing and the focus of this video is going to be on 3D Vision so what
differentiates 3D Vision from its competitors first and foremost is the
fact that it uses the NVIDIA ecosystem so you get a 3D Vision certified display
in this case I'm using the vg236h monitor from ASUS honestly if you're
buying a 3D Vision setup today I would definitely recommend going with one of
the newer monitors with light boost whether it's the BenQ 2420t or the ASUS
27 in I can't remember the model of it but it has light boost light boost makes
all the difference in the world whether you're using Gen 2 glasses the ones that
look like this or generation one glasses
it definitely reduces headaches reduces cross talk between the two images and
provides a much brighter more immersive 3D experience so there's Advantage
number one is you got the NVIDIA ecosystem that is the NVIDIA graphics
card the NVIDIA certified Monitor and the NVIDIA glasses means that everything
works together there's no guess work involved there seems to be a lot of
confusion about AMD's hd3d and that is for good reason I've tried on a couple
occas occasions to get AMD hd3d working
correctly and it can be a bit of a bear
so for one it only works correctly over DisplayPort meaning there's only I
think about two monitors on the market that supported out of the box and number
two is you have to get 3D inserting middleware whereas NVIDIA is actually
doing the work of putting in the driver profiles uh putting in the setup Wizard
and getting you going in a fairly seamless manner
so what are we comparing since we can't compare any AMD cards because it'd be
hard to do apples to apples I want to compare the latest generation gtx680
against its last generation equivalent
the GTX 580 I also want to compare it against the GTX 570 just so you guys
have another point of reference and finally against the GTX 590 that is the
ruler of the roost from the last generation that is basically dual
something between these two because it's got the same number of Cuda course as a
580 but it's actually clocked about like a 570 so that's that's that graphics
card so the 680 uh oh yeah so 3D why do
we need more power for 3D well for one thing let's start I've actually already
run all of the tests for this one so I've pretty much got them here but let's
take a look first at a case study of the GTX 580 so in this case I'm going to
highlight the GTX 580 Row for regular
and then the GTX 580 Row for 3D Vision okay so in terms of average
frame rates we see it requires about
double the processing power in all scenarios minimum maximum and average in
order to enable 3D Vision we get half the frame rate crisis 2 we're going to
see a very different scenario where actually 3D Vision doesn't uh give it
that much of a hit which is something that crisis 2 was actually designed for
with The Witcher we see this scenario again where it takes about double the
processing power remember it's rendering the scene from this angle and then from
this angle and then using the glasses to show only the correct the correctly
angled scene to each of your eyes to give you that 3d effect next Batman
Arkham City we see once again a huge performance hit for enabling 3D Vision
and finally with Skyrim we see the same thing where it takes about double the
processing power so that is one big reason why stereoscopic 3D gaming
enthusiasts might go with something like a GTX 680 over a last generation card
because da you can actually see I'm going to
highlight the GTX 680 with a green color
for new NVIDIA cards okay so the 680
actually performs across the
board almost on par or better or sort of
a little bit lesser or a little bit better than the last generation GTX 590
which if you guys recall is pretty much equivalent to two GTX 5 70s or 580s
somewhere in between that so that puts it a clear double the performance of the
580 here in Battlefield 3 um double the
performance of the 580 here in crisis 2 more than double the performance in the
witch or two please note 20 FPS is not playable you'll have to dial back the
detail levels one way or another this is just giving us the relative performance
in a GPU bound scenario uh next we've got a significant Improvement although
not nearly as huge as some of the ones we've seen before so 60 from 40 for the
GTX 680 versus the 580 and finally in
Skyrim we see yet another doubling of performance so while the regular
performance num showed the GTX 680
definitely beating the GTX 580 here actually yeah I guess it's
pretty much close to double across the board maybe I should have looked more
closely at these yeah okay oh okay
Batman Arkham City not so much but then again not so much
so okay what we've learned is that if you throw more processing power at it in
this case the GTX 680 over the previous
generation GTX 580 remember this is clocked at 1 GHz and that is a flexible
clock speed using GPU boost it'll actually scale itself up in scenarios
where it's not using as much power with 2 gigs of 6 GHz clocked memory this is
using a new 28 nanometer process it consume significantly less power than
the last generation GTX 580 so you can can see here oh no no no
sorry not not against the GTX 580 but against the GTX 590 which is closer to
it in terms of performance so you're uh saving as much as 100 to 150 watts under
load across the board uh compared to a 590 and getting similar performance
getting similar power consumption to the 580 and just blowing it out of the water
in terms of performance especially as you guys can see in 3D Vision so if you
want a game in stereoscopic 3D a GeForce GTX 680 is probably not a bad choice and
thanks to Galaxy for providing the GTX 680 that I use to run these benchmarks
don't forget to subscribe to lonus Tech tips for more unboxings reviews and oh
wow I almost forgot to mention that yes the 680 is the first graphics card from
NVIDIA to support 3D Vision surround off
a single card so using DisplayPort and then dual dvis you can actually run
three displays in 3D Vision in surround mode off a single card and I shouldn't
say it's the first because technically the 590 supports it because that one has
dual gpus to power its three DVI ports
but it is the first single GPU card that not only supports 3D Vision but also
supports 3D Vision surround off a single
card
