Conclusion
There
is acutally one crucial reason why we chose the R9 290X for this test. This chip
is known to become quite hot and to then start throttling. Equipped with the
reference cooler the situation is even worse than with this version of the
DirectCU II cooler, which is actually a powerful aircooler for graphics cards.
Nevertheless, when we started to overclock the card we reached the the
aircoolers limit - apparently. At this point we're going to walk you through the results
gathered on previous pages and then add a few of our thoughts.
Running the card at stock clocks shows, that when we equipped it with the
Raijintek Morpheus scores were on average 1.3 percent higher than with the
aircooler. This is actually already a solid hint, that the card started to
throttle with the powerful DirectCU II aircooler, even at stock clocks. In the
case of Bioshock: Infinite we see that the Morpheus-cooled card is pulling away
by no
less than 5.2 percent. When it comes to stock clocks we also had a look
at two theoretical benchmarks, which are 3DMark and Unigine Heaven 4.0. In
3DMark the differences between Raijintek-cooled and DirectCU-II-cooled are tiny, but in
Unigine Heaven 4.0 there is a 4.8 percent gap.
Once we started overclocking the cards, we noticed that 1150 MHz on the GPU and
1500 MHz on the memory were maximum stable clocks to run the card cooled with
the DirectCU II aircooler. In order to show there is quite some additional potential still
slumbering in the R9 290X cooler (when it receives evern more cooling) we overclocked the
card a little bit higher. In this case we ran it at 1200 MHz GPU clocks and 1500
MHz memory clocks.
Let's discuss the overclocking results now. In 3DMark Fire Strike Extreme we see the scores
increase by 6.4 percent in case of OC with the DirectCU II cooler and 11.4 percent when it comes
to the Morpheus-cooled card. This means there is a 5.0 percent gap inbetween
DirectCU-II-cooling and Morpheus-cooling, although the difference in overclocking is only 4.34 percent.
When we run Unigine Heaven 4.0 we even notice
that the result, in the case of the DirectCU-II-cooled OC tests, dropped below the non-OC
value. This apparently shows there was some rather heavy throttling going on and
the chip is constantly hitting the temperature target. The same card, equipped
with Raijinteks Morpheus did not throttle at all and the performance goes up by
11.4 percent. Overall the DirectCU-II-cooled version is able to gain 8.7 percent
performance with the overclocking and the Morpheus-cooled variant is 11.4 percent
quicker.
On another note we had a closer look at temperatures. There is actually nothing
much to say then the obvious. Even under full load and overclocked the
Raijintek Morpheus-cooled card didn't get hotter than 74°C, whereas the DCU II version ran
at 81°C.
Last but not least we want to add a few thoughts. Obviously, the DirectCU II
cooler is already a well performing piece of hardware. Nevertheless Raijinteks
Morpheus can beat the benchmarks set by ASUS's custom cooler. Considering the
Morpheus equipped with two 120 x 120 x 25 millimeter fans blocks three expansion
slots, and therefore it's substantially bigger than the DirectCU II cooler, we
expected the Morpheus to perform better than the DirectCU II. Apart from that
upgrading an ASUS DirectCU II card with an aftermarket cooler is definitely
questionable, but what really makes sense is putting the Morpheus on a reference
Radeon R9 290X. This will prevent the card from throttling and give you access
to quite a bit more performance. Also overclocking headroom is apparently going
to increase and on a reference R9 290X the 53 Euro, you'd have to pay for the
Raijintek Morpheus, are money well spent.
We gave the
Morpheus from Raijintek
4 out of 5 stars.
