Today we have a chance to take another look at ASUS' Radeon R9 280X Matrix Platinum graphics card since we encountered some problems with our sample that was acting odd. It was simply not stable and was giving strangely bad results in temperature and power consumption, so we have decided to stop by one of the local stores and actually buy a retail card to confirm or contradict the results. Thankfully, it turned out that our sample was really defective, as the new card did much better.
ASUS ships its Radeon R9 280X Matrix Platinum card with the core clocked at
1'100 MHz and the memory at 1'600 MHz (6'400 effective). Compared to the R9 280X
reference clocks the Matrix Platinum has a nice factory overclocking with 100
MHz on the core and the memory. This makes the Matrix Platinum the second
fastest
Radeon R9 280X out of the box at this time after the Toxic from Sapphire.
In the tested games we didn't see the PowerTune Boost in action, the card was
always running at full speed of 1'150 MHz (under load). In Furmark though we did
see it working, when running Furmatk the Matrix Platinum was going up and down
from 1'100 MHz/1.256v to 950 MHz/1.2v.

To cool its Radeon R9 280X Matrix Platinum, ASUS makes use of the same
cooler you find on the Radeon HD 7970 Matrix, the DirectCU II ROG. When you put
the two cards next to each other you don't see any difference. In this case you
get two eight and three seven millimeter copper heatpipes (non nickel plated).
The heatpipes are not in direct contact with the core like the manufacturer
advertise, there is an extra metal plate in-between. Soldered to the heatpipes
you find the fin stack which is being provided with fresh air via two 95mm fans.
Both fans are identical, they carry the model number T129025SU and are being
manufactured by Everflow. Overall the cooler is well made and finished, there is
only the thermal paste which could have been better especially on such a high
end card. The thermal paste used seems to be of mid quality, it is soft but
looks dry.
Most memory chips are actively cooled by the metal plate that covers a big part
of the PCB, they are in contact with the cooling unit thanks to thermal pads.
There are only four memory chips that haven't been included in the loop, the
ones on the right side of the GPU, because they are in the way of the heatpipes.
No surprise here too, the 7970 Matrix PCB put next to the R9 280X Matrix PCB
shows no difference, they are identical. We are talking about a beefed up to the
edge power implementation with 20 phases for the main power design. The GPU gets
sixteen phases (there are five on the reference card), the memory two and the
PLL (VDDCI) two.
The same metal plate that covers the memory chips is also providing active
cooling to the MOSFETs via thermal pads. The manufacturer decided to equip its
280X with a full metal reinforcement (backplate) to prevent bending and also
protect crucial components from potential damage. The 280X Matrix also features
VGA Hotwire,
instant voltage adjustment buttons, the
safe mode button, the
turbo fan button and
soldering points.
Component wise, the Matrix complies with ASUS Super Alloy Power standard.
Checking the voltage regulation chip we find a digital multi-phase controller
labelled Digi+ ASP1211 for the GPU, probably a rebranded CHiL 8228 or 8318.
Additionally, there are two unidentified 2-phase controllers labelled 02=FF 42H
on this card. The one closer to the PCIe power connectors is taking care of the
memory and the one close to the BIOS switch is taking care of the PLL (VDDCI).
The memory chips used are made by SK Hynix and carry the model number
H5GQ2H24AFR-R0C. 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, three VGA Hotwire cables, a
DVI to HDMI converter, a soft CrossFire bridge, a SteelSeries Diablo III
mousepad and the LN2 Mos Heatsink.
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).

While our sample was behaving quite strangely and showed high power
consumption and temperatures which resulted in a low score on our
original ASUS Radeon R9 280X Matrix Platinum review, the one that we got from
retail/e-tail worked like a charm, so thankfully the problem was only
with the sample. Those results also influenced noise levels as well.
The new Radeon R9 280X Matrix Platinum definitely offers great performance, has
one of the best designs on the market, comes with a decent factory overclock and offers quite good overclocking features. Paired up with
one of the top graphics card coolers on the market, it is definitely one
of the R9 280X graphics cards that you should keep your eye on.
We also have to point out that the Radeon 200 series is currently not a
part of the Never Settle Forever program. This may change in the future
but at the moment you don't get any free games for buying a Radeon 200
series graphics card unless the manufacturer specifies otherwise. Other
than the lack of games, the bundle is good, as you get everything you
would expect to get with such a graphics card.

As noted, the ASUS Radeon R9 280X Matrix Platinum uses the same
cooler that we had previously seen on the Radeon HD 7970 Matrix and the
performance on both graphics cards is quite close. This is definitely
not a bad thing considering that it already did a great job back on the
Radeon HD 7970 Matrix and its noise levels are impressive as even under
load, the R9 280X Matrix is quite silent.
There are some drawbacks as well. Despite the fact that we are looking
at a triple-slot cooler, it actually had slightly worse temperature
results when compared to the DirectCU II dual-slot cooler found on the
TOP version of the same graphics card. These are mostly attributed to
the extra copper plate placed between the core and the heatpipes on the
Matrix cooler as well as higher voltage of 1.256V compared to 1.15V on
the DirectCU II Top version.

The ASUS Radeon R9 280 Matrix Platinum is definitely a fast
graphics card and ends up around 7.8% faster on average when compared to
the reference design R9 280X. Unfortunately, it is not clocked any
higher than the Radeon HD 7970 Matrix which even has a slightly higher
1'650 MHz clocked memory while R9 280X Matrix ends up at 1'600 MHz. The HD
7970 Matrix also never throttled down while R9 280X Matrix does, which is a
result of the new PowerTune Boost.
The power consumption under load is higher than on other graphics cards
and since it does not offer much more performance gain it has a slightly
lower performance-per-watt. On the other hand, the power consumption of
the whole system in idle is quite high at 58W, when compared to the 48W
with the DirectCU II TOP version.

Recommendation /

The ASUS Radeon R9 280X Matrix Platinum scored 2.5 stars
in our old review due to a defective sample. The one that we picked up
from retail did much better and it appears that the price is left as the
only issue.
With a starting price of 326 Euros excluding shipping costs across the
EU, the 280X Matrix Platinum is too expensive. That's about 86 Euros on
top of the cheapest R9 280X for example. The price cannot be justified
by what you get since you could get the Radeon HD 7970 Matrix Platinum
which is basically the same card for only 250 Euros.
Furthermore the Radeon HD 7970 Matrix comes with the Never Settle
Forever Bundle.
As a result we simply cannot recommend the 280X
Matrix. If one really wants a graphics card like the
Radeon R9 280X Matrix, we
do recommend to look for the Radeon HD
7970 Matrix instead.

We gave the Radeon R9 280X Matrix
Platinum from ASUS 4 out of 5 stars.
