Sapphire R9-290X Tri-X “Sapphire Takes a Shot at Cooling the Monster”

Overclocking

Overclocking on AMD was fairly straightforward previously but now that so much has been included into the throttling algorithm it has become a bit of a pain to overclock as well.

Your biggest enemy for overclocking the 290X would be heat when we were testing the reference card which meant that it throttled at stock settings and overclocking just meant it throttled faster.

The Tri-X with its ability to maintain substantially lower temperatures saw much better overclocking capabilities as at stock speeds 3D11 Xtreme mode barely hit a peak of 65C which means there should be plenty of headroom to play with.

Testing with the newest version of the Trixx software from Sapphire I was able to push the gpu a little bit but in order to really see what the card could do we had to start feeding some voltage. without any voltage added the GPU stopped scaling at 1110MHZ but once we started slowly creeping up the volts we found that the GPU stopped at right at 1235MHz with full stability which is a pretty massive overclock at almost 200MHz on the core.

The memory I had hope for since it came stock clocked at 5200 but unfortunately those hopes were quickly dashed as the maximum stable I could get from the memory was 5600MHz before stability was a concern. This tells me that maybe while it offers a massive memory bus the sheer larger Qty of memory ICs is a limiting factor as the higher density will simply not scale as high. but overall with the GPU and memory clock we saw an increase in 3D11 Xtreme mode of over 700 Pts which is nothing to sneer at.

TEMPERATURES

To measure the temperature of the video card, we used MSI Afterburner and ran Heaven Benchmark in a loop to find the Load temperatures for the video cards. The highest temperature was recorded. After looping for 10 minutes, Heaven was turned off and we let the computer sit at the desktop for another 10 minutes before we measured the idle temperatures.

 

GPU Temperatures Temperature (Idle/Load)
Nvidia GTX 690 32C/81C
Nvidia GTX TITAN 31C/67C
Nvidia GTX 780 30C/65C
Nvidia GTX 770 34C/79C
Nvidia GTX 760 31C/67C
Sapphire R9-290X Tri-X  35C/65C

The new AMD GPU pumps some serious heat as evidenced by the reference card we tested before but i am happy to report that the new Tri-X cooler keeps the GPU well in check with headroom to push further. Add to this that even under overclock with extra voltage the GPU barely broke into 74C under long term heaven benchmark loading for over 1hr.

POWER CONSUMPTION

Power_Consumption

To get our power consumption numbers, we plugged in our Kill A Watt power measurement device and took the Idle reading at the desktop during our temperature readings. We left it at the desktop for about 15 minutes and took the idle reading. Then we ran Heaven Benchmark for a few minutes minutes and recorded the highest power usage.

The 290X still pulls a lot of power it’s simply something you must deal with on AMD cards as under load they can definitely pull from the wall with some of the best or even a bit more so its something to be aware of and I hope in the respin on the next series they can figure out some ways to save a bit more power to put them more inline with Nvidia offerings.

Sapphire Radeon R9-290X Tri-X When AMD launched the new Hawaii based GPU in the R9-290X it was to huge fan fare but it was not long until many enthusiasts and media alike called foul on the simple fact that the card would ramp up to 94C and sit there while throttling quite alot to maintain the astronomical 94C temp target. Well Enthusiasts have certain requirements when it comes to top end GPUs and one is performance and the other has to due with thermals and fan noise, and well AMD had included a…
