Recently we have changed our method of measuring noise levels. We have built a system inside a Lian Li chassis with no case fans and have used a fanless cooler on our CPU. We are using a heatpipe based passive power supply and an Intel SSD to keep noise levels to a minimum. The motherboard is also passively cooled. This gives us a build with completely passive cooling and it means we can measure noise of just the graphics card inside the system when we run looped 3dMark tests. Ambient noise in the room is around 20 dBa. We measure from a distance of around 1 meter from the chassis and 4 foot from the ground to mirror a real world situation.
Why do this? Well this means we can eliminate secondary noise pollution in the test room and concentrate on only the video card. It also brings us slightly closer to industry standards, such as DIN 45635.
For this review, we couldn't use the passively cooled power supply, however we turned off the case fans to try and achieve a reasonably accurate sound sample of the HD5970 cards.
KitGuru noise guide
10dBA – Normal Breathing/Rustling Leaves
20-25dBA – Whisper
30dBA – High Quality Computer fan
40dBA – A Bubbling Brook, or a Refridgerator
50dBA – Normal Conversation
60dBA – Laughter
70dBA – Vacuum Cleaner or Hairdryer
80dBA – City Traffic or a Garbage Disposal
90dBA – Motorcycle or Lawnmower
100dBA – MP3 player at maximum output
110dBA – Orchestra
120dBA – Front row rock concert/Jet Engine
130dBA – Threshold of Pain
140dBA – Military Jet takeoff/Gunshot (close range)
160dBA – Instant Perforation of eardrum
All of these cards are clearly audible, even when idle, with our noise meter reading under around 50db. Under full load, they can get very loud indeed, with two of them registering around 60dBa.
Although including a video from a camera is hardly scientific, we felt it was worth seeing (hearing)!
good god. that is hilarious. Crysis playable at 5760×1080 at enthusiast :p
lol. Not much more to say to this review. those frame rates are the highest ive seen ever.
Crysis is impressive. it still runs like shit for me at 1920 🙂
Well tickle my tonsels. thats a credit card bill and a half for that system. how much, 5k for the rig ?
The ducati analogy is interesting. I laughed initially but you have a point and I get where you are coming from.
Sorry at the end of the day however, I couldn’t even begin to contemplate spending almost 2k on a Crossfire setup.
CPU £700, PSU £250, Memory £150, Graphics £1800, Case £250, Hard Drive £300. Cooler £100.
Lovely. liked the videos too, that memory is wicked, is that crucial ballistix tracer ?
Its £100 less than the ARES, so at least thats something.
Great cards and they look beautiful, much nicer than ARES imo. Isnt AMD’s new range coming out in a few months? surely makes these pretty much redundant now.
Gaming on these for a month would give a nice electricity bill. AX850 was getting warm? thats a serious output level.
How many of these are XFX making? 500 ?
The cost is so high probably to cover, or help cover the R&D by XFX. I can’t see them selling too many of these, id love to get sales figures, out of curiousity.
i love these cards, but I couldn’t afford anything close to this. I saw a great review of this on hardware heaven too a few weeks ago.
@ Robert – yeah it would heat up the house, so you might save money long term. not sure of the overall output, I just measured the cards.
@ Brad – yes , ballistix tracer – great memory and very underrated, ive had those to 2ghz.
@ Sam – I dont think any of us would spend 1800 on a system like this, well Id love to, but im just like you guys, a pauper 😉
@ Joe – I haven’t read it, but I am sure it is good, Stuart is one of the best reviewers on the net.
@ Melted Cheese Tech – I honestly have no idea of the amount of cards produced in this range, I wouldn’t say very many. ill find out if I can.
@ Trevor – I don’t think your scenario just relates to Graphics cards, but yes a new range of cards, not long away.
Ok I just called XFX, they only made 1000 of these, worldwide. quite a limited run.
Very nice, apart from the noise ratings. crazy performance.
… hmmm…
If I win euro millions, I might consider setup like this… 😀
the toys of the rich and famous. if only 🙂
Those are really sexy looking cards – love the colours. they seem rather loud, but its part of the trade off for ultimate performance.
very nice, wouldnt make me much of a better gamer however, I suck 🙂
I have been saving up for one of these since it was announced, almost have the money now, but it will probably all be gone by the time I get it together 🙁
Very nice performance to say the least. It seems totally overkill for what most people need, but hell if you have three monitors and a core i7 970 or 980x, SSD, 1200W psu, why the hell not ? 🙂
On the benchmark reviews on haven the person says that a nvidia 460 overclocked gets 30 fps average? i scored 68 fps with sli’ed 260 1 year old videocards. DX11 in this benchmark test is backwards compatible so that is with a dx 11 render… So I question the validity of that statement — “For comparison, an overclocked GTX460 scores an average of 37.1 fps. Scaling in Crossfire X is very good with the average frame rate jumping from 62.6 to 114.3 when another card is added. On a side note, we expect to see Tesselation improving with the new range of ATI cards.”
With that said, my minimum fps was 10 fps higher then the minimum fps logged on those bench tests. So your buying overhead fps ;(.
