Today we're having a closer look at Gigabyte Radeon R9 270X OC. This card features a custom PCB as well as a custom cooler. Other than that there is even a factory overclocking. These are three reasons to definitely have a look at this card, and when we tell you that it even comes with an attractive price, then you should definitely give the following pages a shot.
Gigabyte ships its Radeon R9 270X OC card with the core clocked at
1'100 MHz and the memory at 1'400 MHz (5'600 effective). Compared to the R9 270X reference clocks the
Gigabyte OC has a
shy factory overclocking with 50 MHz on the core. Unfortunately no factory
overclocking was made on the memory.
During our testing we didn't see the PowerTune Boost in action with the Gigabyte
OC, the card was always running at full speed of 1'100 MHz under load even under
Furmark.

To cool its Radeon R9 270X OC, Gigabyte makes use of their very own
WindForce 3X cooler. However it is not the WindForce 3X we are used to see, this
one is completely different despite the same name. In this case you get only two eight millimetres copper
heatpipes (non nickel plated), there are no six millimetres. The heatpipes are not in direct contact with the
core, there is an extra copper plate in-between. Soldered to the heatpipes you
find the fin stacks which are being fed with fresh air via three 80mm fans. They
are manufactured by Everflow, carry the model number T128010SU and have been
inclined in order to blow the air away better at the top of the card. manufactured by Everflow. Overall the cooler is well made and finished,
there is only the area around the copper base that didn't get enough attention
leading to what we call an industrial look. The copper base has been well lapped
but doesn't have a perfect mirror finish. The thermal paste used is of good
quality, soft and hasn't been uselessly spread in large quantity all around the
chip.
Around the base you find an aluminium part which is used to fix the cooler to
the PCB and also to cool all memory chips thanks to thermal pads. The MOSFETs
are also actively cooled but with a separate little aluminium heatsink, right
below a fan.
At closer look at the custom PCB shows that Gigabyte equipped its card with
a so called 6+1+1+1 phase
power design where the GPU gets six phases and the memory, PLL (VDDCI) and PCIe
one.
Checking the voltage regulation chip we find a digital dual output 6+2 phase PWM
controller IR3567A from International Rectifier for the GPU and memory voltage
regulation. There are also two uP1542S from uPI Semiconductor ont the PCB, the
one closer to the end of the card takes care of PLL (VDDCI) while the one close
to the PCIe connector takes care of the PCIe.
The memory chips used are made by Elpida and carry the model number
W2032BBBG-6A-F. They are specified to run at 1'500 MHz (6'000 MHz effective).
The card ships well bolstered in a foam made mold.
Bundled with the graphics card there is a software CD, an installation manual,
a soft CrossFire bridge and two power adapters (2x Molex to
PCIe-6pin).
Idle, temperature is
taken after 15 minutes @ lowest, 40 %, 50 %, 70 % and 100 % fan speed.
Room Temperature: 25°C
Temperature under
Furmark
For FurMark, temperature is taken
after 15 minutes of GPU Burn test at lowest, 40 %, 50 %, 70 % and 100 % fan speed.
We stopped the test when the GPU temperature hit 90°C.
Room Temperature: 25°C
Temperature and
fan speed under BattleField 3
For BattleField 3, temperature and fan speed
values taken, are the highest achieved after 1 hour gaming @ auto fan
speed.
The "Performance Index" value is calculated as the sum of all
benchmarks results divided by the amount of games (3DMark and Ungine not
included into the calculation).

The Radeon R9 270X OC from Gigabyte did good in our
test parkour despite it doesn't have really anything special. The card features a
custom PCB, a little factory overclocking on the GPU and a
great cooling solution. We noticed only one major flaw concerning the
cooling solution that could be quieter. Also Gigabyte could have easily pushed the factory overclocking
further since they equip their card with memory chips
rated at 1'500 MHz. Other than that we like its design and aggressive
pricing.
Again we have to point out that the Radeon 200 series is not currently
part of the Never Settle Forever program. This may change in the future
but at the moment you don't get any game for free buying a Radeon 200
series card unless the manufacturer specifies otherwise.
For its Radeon R9 270X OC, Gigabyte makes use of a
downscaled version of their WindForce 3X cooler. This version offers
great cooling performance but could be quieter. Indeed the manufacturer
adjusted the fan profile in the BIOS for performance over silence. We
hope Gigabyte will release a BIOS update to change this.
In idle the card is very silent and under load it can be described as
silent.

In the tested games, the Gigabyte Radeon R9 270X OC is on average
3.15 % faster than a Radeon R9 270X with reference clocks and 10 % faster than
its predecessor the Radeon
HD 7870.
A closer look at power consumption shows, that our test system, equipped
with the Gigabyte OC, burns 49 Watts under idle conditions and 232 Watts
under load. In both cases those are really good results for a R9 270X.
Compared to a reference clocked R9 270X, the power consumption of the
Gigabyte OC is only 4 % higher.

The Gigabyte OC is one of the cheapest Radeon R9
270X. At the time of the review, the Gigabyte OC can be found at a starting price of 163 Euro and the cheapest offer for a R9 270X
starts at 158 Euros excluding shipping costs accross the EU.
Since the graphics card only has a noise issue that can be fixed
changing the temperature target via sotfware, we recommend this card for
people looking for a cheap and good Radeon R9 270X.

We gave the Radeon R9 270X
OC from Gigabyte 4 out of 5 stars.
