Sapphire R9 Fury Tri-X OC Physical review.


It's hard to see but Sapphire put a small piece of plastic over the interposer to protect it. It isn't perfect since you can still break the interposer but much better than nothing.



Buildzoid's GPU reviews explained

Specs
3584 stream processors clocked at 1040mhz
4GB of HBM clocked at 500mhz on a 4096bit bus
2 8pin power connectors officially supporting up to 375W
Core clock throttling temperature: 85C°
1 HDMI port3 DisplayPort

Physical Specs
length: 320mm
width: 110mm
height: 2.5 slots

Cooling: 10/10
 When I first played a game on this card I knew I was gonna end up giving away points like they grow on trees. And why wouldn't I the cooling on this card can get the same temperatures as a custom water block. I currently don't have the equipment necessary to do proper noise testing but just ot give you an idea of the fan noise I'll tell you this. With the GPU at 0RPM my sound meter reads about 51.5dB sitting 8cm from the GPU. With the fans at 40% it reads 52 dB. At 55% it gets 59dB. At 75% it reads 66dB and at 100% it reads 73dB. I'd recommend running the card around 55-65% fan speed since that's when the noise temperature trade off is quite reasonable.

VRM: 9/10
Core
- 6 true phases provided by an IR 3567B
- 1 low side IR 6894 MOSFETs providing 105A per phase at 100C case temperature
- 1 high side IR 6811 MOSFET providing 44A per phase at 100C case temperature
- 200KHz up to 2MHz
VRAM
- 1 phase
- 1 low side IR 6894 MOSFETs providing 105A per phase at 100C case temperature
- 1 high side IR 6811 MOSFET providing 44A per phase at 100C case temperature
VAUX
- 1 phase
- 1 low side IR 6894 MOSFETs providing 105A per phase at 100C case temperature
- 1 high side IR 6811 MOSFET providing 44A per phase at 100C case temperature
The low side on this VRM is a beast. However like on the R9 290X the high side here is iffy. If you keep it cool you'll be fine but if you let the VRM get hot you can't let the card pull much more than 500W because you'll be risking burning out the high side. There are plenty of cases of people doing this on the R9 290X. The Fury uses much less power so it's not as much of a risk but keep it in mind if you're going heavy on the voltage and not using LN2 because the VRM can easily overheat. Also do note that in certain situations the card has coil whine. Not enough to be as annoying as say loud fans but enough to be noticeable so keep that in mind. I will try somethings with the card to get rid of the coil whine and will put that into my Fury volt modding post which is coming soon.

Extras:
+1 Dual BIOS
+1 0RPM fans in idle 
+1 VRAM cooling
+1 Backplate
+1 Silicon Interposer protector

Overclocking
The highest I've managed to push this card to was 1144/566mhz using Sapphire Trixx. These were not 100% stable clocks. My 100% stable clocks are 1100/550mhz and require a custom fan curve to keep the GPU sub 55C core temperature. The GPU does not clock well and instabilities are hard to catch. I had the card running perfectly OK at 1135mhz core clock for several hours and then it black screened out of no where when playing a relatively light game. This leads me to believe that the dynamic power management is holding the card back.

Conclusion: 24/20 Why is the score so high?
I love this card. It is by far the best GPU I have ever had. It is way way quieter and cooler than all my past GPUs. It's so good a card that I'm terrified of volt modding it(also because the 3567B has the weirdest voltage sensing circuit I've ever dealt with). Which I'm working on as I finish up this review. I don't really have much to say. I love this card it provides an excellent platform for volt modded overclocking.

The voltmod guide for this GPU is now up

Thank you to CoolerMaster for providing the V1000 PSU that was used for this review.

  1. how far can you undervolt at stock clocks, and how high is power consumption via furmark?

    1. As of right now undervolting the card requires physical mods for which I lack the resources. As for power draw under Furmark I will add it soon.

    2. Thanks for answering that quickly.

      So, just to get it straight - no software undervolting via afterburner or trixx - is that only temporary or likely to stay like this?

      Then, how low can you set the Power Limit and still stay at stock clockings?
      Really interested in getting this card - just a bit concerned about wattage.

      Again, appreciated :)

    3. Lowering the power limit will just make the card throttle. What PSU do you have? because in games the card only pulls about 200-250W in Furmark it uses about 340W because Furmark breaks all the smart power saving features AMD put on the card.
