ASUS GeForce GTX 650 Ti Boost DirectCU II OC Review + SLI
Category : NVIDIA
Published by Christian Ney on 25.04.13
Like many other manufacturers ASUS released its very own version of the GTX 650 Ti Boost using a custom design PCB and a custom cooler. The latter is a smaller and cheaper version of the now well known DirectCU II, hopefully as good as the other ones from the series. The name says by itself, the card is shipped with a factory overclocking. In this case the GPU runs 52 MHz higher than the reference model.
With the ASUS GeForce GTX 650 Ti Boost DirectCU II OC you get a factory overclocked
card with a custom PCB cooled by a DirectCU II cooler. The ASIC quality
measured on our sample was 71.7 % which is about average.
About ASIC quality:
Looking at the clock speeds we see that the GPU runs at 1'020 MHz with a
typical boost of 1'085 MHz, 52 MHz higher than the reference model. There are only three cards that feature higher
clocks you can find in Europe. If you'd like to find them, check out our market overview:
the SuperClocked from EVGA, the iChill HerculeZ 2000 from Inno3D and the OC from
Gigabyte. Like most other manufacturers no factory overclocking has been made on
the GDDR5 memory, therefore the clocks remain at 1'500 MHz (6'000 MHz effective) following
nVidia's recommendations.

As mentioned previously, this card from ASUS makes use of the
custom PCB. ASUS engineers reworked the circuitry and the power design but didn't
go too far. In this case you don't find a digital power design nor more phases.
The only major changes apart from the PCB design itself are the use of super
alloy components and different but still cost effective voltage controller. Therefore you get
an analogue power design with five phases, where the GPU gets four phases and the memory gets one phase.
The voltage regulation chip used for the GPU is a RT8867A from Richtek
Technology. On the memory power design side you find an APW7165A from ANPEC
Electronics.
ASUS ships the GeForce GTX 650 Ti Boost with a smaller and cheaper version of the dual slot DirectCU
II cooler. This one comes with two heatpipes, that feature 6 millimeter
diameter. Both heatpipes establish direct contact via the direct touch
technology. Furthermore there are two 75 millimeter fans and no aluminium fins. The latter explain
itself when you look at the heatsink, which has been made from aluminium
entirely. Very cheap but in our test it proved to be very good - so why not.
Although this cooler is a smaller version, it is longer than the card's PCB by
2.4cm lenghtwise, which ends up with a total card lenght of 21.50 centimeter. Also because of the two heatpipes the cooler is 0.8
centimeter higher.
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).
Bundled with the graphics card there is a documentation, a driver CD that
includes the overclocking tool too, a power converter (2x Molex to PCIe-6pin) and a DVI to VGA adapter.
That's about all you need with such a card.
The card ships well bolstered in a foam mold.
Idle, temperature is
taken after 15 minutes @ 30 %, 50 % and 100 % fan speed.
Room Temperature: 25°C

For the price we took the lowest price available on geizhals.eu,
on the day the review has been published.
This GeForce GTX 650 Ti Boost DirectCU II OC from ASUS has
been able to convince us. The cooler is really good and able to keep the card cool and noiseless
being in idle or under heavy 3D load and we also like its design.
Furthermore it's
one of the
highest clocked GeForce GTX 650 Ti Boost around.
Meanwhile we think the card is a bit too expensive although you get a very good
cooler and high factory overclocking. You can find it for 15 Euro more
than the cheapest GeForce GTX 650 Ti Boost and if you look at
geizhals.at, it's the most expensive Ti Boost. In thise case ASUS could
have done a factory overclocking on the memory and used a better quality
heatsink.
- Noiseless in both 2D & 3D
- Bundle
- Design
- Factory Overclocking
- Price
- Cheap heatsink
- No factory overclocking on the memory
Performance

Thanks to the factory overclocking, the DirectCU II
OC is about 3.0 % faster on average in games than the same card with reference clocks.
The power consumption in idle is the same as the reference card from
nVidia. Our entire setup was
drawing no more than 50 Watts.
Under load we measured "only" 171 Watts. That's 13 Watts
less than the reference card, which ticks 52 MHz lower. The difference lies
with the custom PCB and the use of better power components.
In the end the DirectCU II OC benefits
of a much better Performance/Watt ratio and a lower Performance/Price ratio.

Recommendation

-
This DirectCU II OC variant offers exactly what you
would expect from a GeForce GTX 650 Ti Boost. It features a noiseless and powerful
cooler as well as a custom design that makes the power consumption go
down. The only contra we found it is the price which is in our opinion 5
€ too much.
- Mid-Range Gaming
We gave the
GeForce GTX 650 Ti Boost DirectCU II OC from ASUS
the almost perfect award of 4 out of 5 stars.
