With the GeForce GTX 760 DirectCU II OC, ASUS has also a GeForce GTX 760 in its portfolio which features a factory overclocking. Additionally you get a slightly revised version of the DirectCU II cooler, which is know for great cooling performance at a low noise level. Overall we're curious to see what this thing can do.
With the ASUS GeForce GTX 760 DirectCU II OC you get a factory
overclocked card which features
a custom PCB as well as a custom cooler. The ASIC quality measured on our sample
was 76.7 % which is ok considering the average being at
73 % on the cards we had at hands.
About ASIC quality:
ASUS's GeForce GTX 760 DirectCU II OC is based on NVIDIA's Kepler GK104-225
A2
chip, which is manufactured by TSMC using the latest 28 nanometer process
technology. With the GeForce GTX 760 you get six SMX units which results in
1'152 CUDA cores. Following the specs further, there are 96 TMUs, 32 ROPs, a
256 bit wide memory interface and 2 Gigabyte of GDDR5 memory, which is clocked
at 1'500 MHz (effective 6'000 MHz). In the end there is a memory bandwidth of
192 Gigabyte per second. Concerning the GPU's clock speeds it runs at a base
clock of 1'006 MHz and a boost clock of 1'072 MHz. During our tests the highest
boost clock we measured was 1'149 MHz and the average boost clock was also 1'149 MHz.
The ASUS GeForce GTX 760 DirectCU II OC supports NVIDIA's GPU Boost 2.0. The first version of GPU Boost stopped overclocking the GPU when a certain power target was hit. This new second version of GPU Boost stops overclocking the card, when a certain temperature is being reached. This makes sense since the temperature is the bigger inhibitor than the power target in most cases. In this case the temperature target is 80 degrees Celsius. In other words, as long as the GPU runs at less than 80°C it will keep overclocking until the maximum frequency has been reached. This is why in our case the average boost clock was
77 MHz higher than the typical boost clock NVIDIA advertises.

ASUS decided to equip the GeForce GTX 760 DirectCU II OC with a slightly
reworked version of the well known DirectCU II cooler. In this case you get four
heatpipes, whereas the two in the center have a diameter of eight millimeter and
the two on the outside have a diameter of six millimeter. The heatpipes itself
have been nickel plated and they are soldered to the fin stack, that ofers 1'963
cm2 of dissipation area. The reference cooler only offers 1'230 cm2 of
dissipation area. The heatpipes establish direct contact to the GPU. ASUS
also thought about actively cooling the MOSFETs with an heatsink. Between the cooler and these chips there are thermalpads, which establish a
direct contact. A closer look at the fans shows that they feature a diameter of
75 millimeter and they can draw up to 0.35A on 12 volt each.
Shifting focus to the PCB shows, that it has the same length like the reference
design, but thanks to the fact, that the cooler is shorter, the entire card
becomes shorter than the reference model. In total ASUS has been able to save
2.4 centimeter in length. On the other hand ASUS had to increase the height of
the card by 1 centimeter to fit all the components on the PCB.
A closer look at the PCB shows that ASUS equipped this card with an analog
five phase power design. The GPU gets its current from four phases and the
one phases left takes care of the memory. NVIDIA's reference design
features four plus two phases, which means that the memory get two and not only
one phase on the later. Don't worry, ASUS' single phase is stronger than
nVidia's two phases.
Checking the
voltage regulation chip we find a RT8867A 4/3 phase analog PWM controller from
Richtek.
The reference card from NVIDIA makes use of a NCP5392P from ON Semiconductor.
Furthermore there is an
unidentified Richtek 1-phase PWM labelled 02=FA F0X taking care of a stable
current supply for the the memory.
The memory chips used are made by Hynix and carry the model number
H5GQ2H24AFR R0C. They are specified to run at 1'500 MHz (6'000 MHz effective).
A closer look at the delivery shows, that there is the graphics card itself
wrapped in an anti static bag, which is placed in a foam mold. Furthermore tehre
is a manual, a driver CD, which also contains ASUS overclocking software GPU
Tweak as well as an adapter cable from 2 x 6-Pin to 1 x 8-Pin.

ASUS' brand new GeForce GTX 760 DirectCU II OC is quite a nice
piece of hardware. This custom card is not only quicker than a reference
GTX 760 it also features ASUS' DirectCU II cooler. Furthermore, since it
is an "OC"-model, this card boasts quite a decent factory overclocking,
which gives you a slight performance boost. On the other hand this
bundle lacks a game or just a special goodie, which would make gamers
even happier when buying this card.

GPU Temperatures were good at maximum of 80°C
under heavy FurMark load with the fans revving up to a mere 30 percent of
their actual maximum. ASUS did a really good job, when it comes to the
noise level of this cooler. In idle the card is inaudible and even under
load the card can be described as subjectively speaking very silent.

A closer look at overall performance shows that the
GTX 760 DirectCU II OC is
2 % faster on average in games than a reference GTX 760.
Taking a look at the clock speed shows that this card clocks at 1'149 MHz
on average, when applying heavy 3D loads. At this point one can really
see GPU Boost 2.0 doing it's job, since it always tries to get the
maximum clock speeds out of the card, without overstepping the 80°C
temperature target.
A closer look at power consumption shows, that our test system, equipped
with the GTX 760 DirectCU II OC, burns 60 Watts under idle conditions
and 217 Watts under load. Since we have only one other GTX 760 to
compare this card to, we see that this ASUS card need 10 Watts more
under Idle than EVGA's GTX 760 SuperClocked ACX and under load the
difference becomes 12 Watt. Which is bad as the EVGA card is faster. We
have been used to see DirectCU II cards with high idle power consumption
due to particular beefed up power design so that's "normal" but on the
other side the power consumption under load was always better and not
worse like in this case.

Should you be looking for a graphics card in the
performance segment, that features a factory overclocking and an
excellent cooler, then the ASUS GeForce GTX 760 DirectCU II OC is going to be a great choice.
These days this card changes owner for 238 Euro, which isn't exactly a
bargain.

We gave the
GTX 760 DirectCU II OC
from ASUS the very good 4 out of 5 stars.
