For this edition of ASUS MARS Graphics card, ASUS has thought about something different than their usual recipe. This time, there aren't two high-end chips but two GTX 760 mid-range GPUs. You can find these chips on one single PCB combined with a powerful and beautiful cooler. Other than that the GPUs received a really decent factory overclocking and we're curious to see what this card is capable of.
Presentation
ASUS has definitely outdone itself and has brought quite a surprise with the
launch of the ASUS ROG MARS 760. The new ASUS ROG MARS 760 is actually the first
dual-GPU card based on two GK104-225-A2 GPUs, or simply, two GTX 760 GPUs placed
on the same PCB. If you actually stop to think about it, then you might stumble upon the fact that one GTX 760 card
comes at quite a decent price point which puts the ASUS ROG 760 at quite good
price/performance ratio on the market. So putting two GTX 760 GPUs on a single PCB and
then making them work together with a decent PLX chip sounds like quite a plan, a plan that might scare off even the GTX 780 or the mighty
GTX Titan.
With such a custom card, it's quite obvious that there is nothing according to
reference specifications. There is a brand new cooler, a completely custom PCB and even a
factory overclock on both GPUs. ASUS is not making any exceptions with this MARS
card, as their ROG department has really decided to push the limit to a whole
new level.
We will start off with frequencies. The base clock of this beast is set at
1'006 MHz while the Boost clock is at 1'072 MHz. After putting some load on
these two chips we see that a maximum Boost clock goes all the way up to 1'123
MHz while the average Boost clock is at 1'123 MHz. On this card, the NVIDIA Boost technology is
both temperature and power based, the latter being predominant, leading to more
consistent results. The
only time when the maximum Boost clocks drop is when we are putting heavy
load on these GPUs using Furmark. Luckily load like this is not going to be
applied in games so the ASUS ROG MARS 760 should stay at its maximum
Boost almost the entire time. Another interesting feature is the fact that there is an SLI connector, which
basically means that Quad-SLI setup is possible when two ASUS ROG MARS 760
graphics cards are paired. The PLX chip, which is there to make the two GK104's
work in tandem, is the PEX8747.
