vengance gaming to learn more welcome to what amounts to basically an unboxing
and second look at the GeForce gtx770
direct to you to from ASUS now I call it a second look because I've already had
this card out of the box and I have
actually already had a chance to Benchmark it so okay I'm going to spoil
the surprise a little bit it's a GeForce GTX 770 which means it's based on the
same GK 104 core as the gtx680 a fully
enabled core to be more clear so okay so
it's a GTX 680 no because it's clocked
higher this one in particularly because it's an OC level card and it also has 7
GHz gddr5 memory as opposed to the 6 GHz
gddr5 memory that we found on the original GTX 680 now the first things we
find inside are a nice black ASUS box with some gold printing on it as well as
a bunch of accessories that we didn't get with our reference card that came
direct from NVIDIA so it's interesting to see what ASUS includes so they've got
a quick start guide as well as some drivers and GPU tweak software that
you'd do well to download directly from the ASUS website and finally last but
not least a dual six pin to single eight
pin PCI Express power adapter next up is
the card itself now the first thing you're going to notice about it in all
likelihood is going to be the cooler the
direct CU 2's cooler gets its name from The Copper heat pipes as well as the
direct contact that they make with the GPU itself this improves thermal
efficiency as well as improving overall performance of the card especially in an
overclocked environment there are two fans on it Each of which is sealed
against dust making it dust proof and adding to the longevity of the card and
allowing them to cover a wider area of
the card itself providing more air flow not only to cool the GPU itself because
it's connected with these nice fat heat pipes to all of these fins but also the
other components under the heat sink fins all over the entire PCB of the
graphics card on the back of it we find not a whole lot that you can see except
for a back plate this contributes to the rigidity of the card which is especially
important when cards are get longer and heavier and they're installed in chassis
that only really fasten them at the screws at the top here as well as the
PCI Express slot and the last thing that we see are a couple of diagnostic LEDs
right under the six pin and 8 Pin PCI Express connectors that tell us if
there's any kind of a power problem causing the card to be nonfunctional
direct cu2 cooler are also well regarded for their quiet operation and we did
indeed have the same experience with this card so I can happily say that it
sits proudly with the other direct cu2 cards that we've had the opportunity to
play with here's a cool feature for liquid coolers and Tweakers and just
generally guys who are willing to push the limits of their Hardware sort of no
matter what the uh no matter what the risk by simply removing four screws on
the back of the card you can remove the entire direct cu2 cooler this allows it
to be cleaned or just completely removed and replaced with something else should
you see fit although most people
probably aren't going to bother with that you will have to break a seal in
order to get the cooler off
however that risk is entirely up to each
individual user and check that out it comes apart just like that to reveal the
way that the card is cooled so we get thermal go on the GPU itself no thermal
pads present on the memory because of what I mentioned before the way that the
direct2 cooler provides so much air flow to the rest of the card you don't really
have to worry too much about that we can see the entire 8 plus 2phase power
design this is compared to okay so 8 plus 2phase digital power design
compared to the 5+ one phase analog power design that you're going to find
on a reference card and a dedicated heat sink for the mosfets themselves that
allows that that's the hottest part of the power delivery that allows them to
stay cool now there's more to a custom PCB design than just designing the PCB
you also have to use higher quality components if you're going to get any
benefit out of it whatsoever so that's where isus is sap or super alloy power
components come in most of the power
delivery circuitry actually is comprised of these specially designed components
that ASUS has engineered in order to deliver better over clocking better
efficiency cooler operation longer Lifetime and this is sort of this hits
pretty close to home for me less coil wine because coil wine is just annoying
and then mind you so are dead cards and cards that consume more power for no
reason but that was the rationale behind
redesigning it in order to use their own components it was to achieve all of
those things but how did it all work out in the end my final word on this card is
going to be about GPU tweak and the actual results that we were able to
achieve because all of this is fine in theory but what does it yield in the
real world our direct cu2 card
overclocked higher than our reference card take that for what it is this is a
very small sampling but in our experience we did manage to get a
slightly higher sustainable boost clock
okay so it was only 35 or so some odd
megahertz higher than this particular card but there you go higher is higher
and we did get better performance out of a direct cu2 card than we did out of a
reference card also using GPU tweak was
a fairly good experience I've never used it before at least not extensively but
it does have some special features that allows it to work better with ASUS cards
particularly the ones that use their custom vrm designs that are pretty
different from all the other things that are out there on the market and with the
integrated GPU Z utility as as well as the ability to set up monitoring as a
widget it's pretty handy thanks for checking out my unboxing and first look
at the gtx770 direct to YouTu from ASUS
