Exploring Pump Noise
Let’s go back in time a few days to right before the Radeon R9 Fury X’s launch. Our German team (the guys measuring thermals, power and acoustics) were only able to test the new card for a few hours due to a scarcity of press samples. But this short time period was enough to give us an earache. Our colleagues reported the same problems, which confirmed the existence of a whistling noise. In addition, there was some kind of buzz. The latter is a low-frequency, oscillating grinding noise. These noises combined to form annoying acoustic fireworks.
Since we weren’t the only ones who contacted AMD about this, all reviewers received a preemptive email that was supposed to calm and reassure people:
Very small batch?! We wanted to know just how small this batch really was, and got our hands on our own retail sample from Newegg, just as a customer would. Our model was made by XFX, and we'll say more about it in a small footnote at the end.
Apart from the Cooler Master label being somewhat off-center, our press sample and the retail board, along with their pumps, are identical. By now, there’s talk on some forums about other labels and even engraved Cooler Master logos, but we haven’t seen a card like that in the lab yet.
The retail card’s noise profile is different from that of the press sample in the sense that the XFX card doesn’t just have a whistling noise, but also a lower saw-like noise. Really, it sounds like a buzz saw with an oscillating out-of-balance blade. It even includes the saw’s motor noise. The graphics card’s obviously not as loud, but the acoustic profile is quite similar. Consequently, we’ve labeled this noise “buzz.”
We tried to trace the origin of the sound with a special microphone designed to measure structure-borne noise. This led us to where the small heat pipes are connected above the voltage converters. Even though these are designed poorly from a flow perspective (sharp bends, unnecessary decreases in diameter, possibly a rough inner surface), they were neutral as far as the noise was concerned.
This means that micro-bubbles aren’t the culprit. This conclusion is confirmed by the fact that decreasing the pump’s voltage to slow it down halves the whistle's frequency, but doesn’t make it any less loud. All that remains as a possible source is the pump itself.
Comparatively, at least it doesn't reduce performance like the last 0.5 GB on the 970, and I don't remember tom's being on Nvidia's case about that much more serious issue.
Somehow I don't think a lot of PC stuff is rigorously specified. In this case I think samples were signed off by sales and marketing. This is how much of the PC industry is run.
They are really changing the pump. Someone tried to upper their margins by cutting quality. But all in all even the older pump is very quiet and with the right version situation gets even better.
The FuryX is very good card. Luckily so is 980ti even in bigger measurements! Interesting to see how air coolet Fury will change the situation. All in all 980ti will make FuryX cheaper and FuryX forced the Nvidia to make something else than TitanX to customers. Competition is good!
980ti is very good card and FuryX allmost gets there. Because of AMD problems with DX11 the situation may be reversed in DX12 games so in longer run the situation is even as it should be for the customers.
Hopefully we will soon see some retake when Toms will get the upgraded pump to the test. Also it seem that some parts that are not water cooled can get quite hot, so Air cooled basic Fury will be very interesting card to be get tested.
The situation in GPU part is better than for long times! The next year will be even more interesting, because we may see first finvet based GPUs and also second generation of HBM.
This is a follow-up, not the launch review. In the first part of this follow-up with power consumption measuring I have tested both cards in a lot of games and applications - together with the specific power draw for each card in each benchmark. This is more than other sites published. 10,240,000 single values - this wasn't done in a few hours.
Simply use the slider pics to compare power consumtion, performance and watts/fps. :)
This is only one example:
(the original, detailled review was in German)
Interesting that you see AMD somehow forcing Nvidia's hand, maybe Nvidia is just doing it's own thing and AMD are the one's playing catch up and having to release untested products in order to try and stay in the game. The GDDR5 bit is amusing enough as it indicates a design change that could explain why there was mention of the cards RAM using a fair bit of juice, it's also good to know that it can use Mantle but I didn't see mention of Freesync?
