As stated previously, for your
competitive overclocking
endeavours, it is best you look
for another GTX 780 Ti, but for
your gaming needs there isn’t
a better GTX 780 Ti that we
can think of.
Clock speeds is where
GIGABYTE have been
particularly aggressive,
delivering a boost clock of
1150MHz out the box. Not
only is this a higher clock
than on any other
GIGABYTE graphics card, but
it’s a mighty 23.9% higher than
what NVIDIA will provide you
with on the reference GTX
780 Ti. Even more impressive
though, is that the real clock
under gaming and benchmark
conditions is even higher at an
astonishing 1215MHz. At these
frequencies, the performance
differences between this card
and the reference 780 Ti are
made vividly clear.
While the reference GTX 780
Ti is a fast card, just a little
faster than the Radeon R9
290X, GIGABYTE’s 780 Ti GHZ
Edition card, simply distances
itself away from the 290X by
some margin. To put this into
perspective, you will notice
that an overclocked Radeon
R9 290X is slower in all
tests, when compared to the
GIGABYTE 780Ti GHz Edition.
Out the box performance is
phenomenal making this the
fastest graphics card we have
ever had the opportunity to
test. The numbers are more
than compelling and be it
you’re gaming at 1080p or
UHD resolutions, this is the
graphics card you should
consider over and above all
others (dual GPU solutions
withstanding) as we doubt if
there will be any other vendor
with a 780 Ti clocked this high.
Our attempts at further
increasing the clock speed
on this graphics card were
quickly curbed. We managed an
additional 82MHz, on the core,
and 800MHz on the memory
before things became unstable.
That’s a mere 6% overclock on
the core, but do consider that
it’s 6% on top of the 23.9% you
buy the card with. Providing
additional cooling to the graphics
card didn’t help, thus our
conclusion is that you’re likely
in need of more VDDC voltage.
Unfortunately GIGABYTE”s own
software will limit you to 1.21V
much like all other voltage
control software. There are
several ways to get around this,
but we would caution you about
this as you do run the risk of
damaging the card or at the very
3502,696
least voiding your warranty.
Should you need additional
performance for competitive
overclocking purposes, then
perhaps you should consider
one of the other cards that are
geared more specifically to
overclocking. For your gaming
purposes however, GIGABYTE’s
GV-N78TGHZ is near perfect. It
runs cool, hardly audible and it’s
incredibly fast. GIGABYTE’s best
graphics card to date by far.
[ The Overclocker ]
Summary
GIGABYTE has managed
to make the fastest single
GPU graphics card to
date with the GV-N78TGHz.
With such a high clock
speed and impressive
cooling capabilities,
it delivers cracking
performance that has
yet to be matched by
any other. There is little to
no incentive for looking
elsewhere for your gaming
needs.
Would you buy it?
Yes, without hesitation!
