It's also true for a single dual GPU card in a well cooled case, see here for example:
http://ht4u.net/reviews/2009/amd_ati_radeon_hd_5970/index15.php
My 295 was much louder in idle and a bit more quiet under load (something around 5 sone I'd guess) as compared to the 5970 and it was annoying as hell (I guess somewhere above 4 sone it really starts to piss you off) because it even was loud in heavy firefights with headphones on :\ I never had problems with microstuttering, but noise alone is a good reason to never buy a dual GPU card again. The 5870 is hardly noticeable when idle and reasonably loud under load and still offers enough performance for almost any game. I'm even willing to sacrifice some FPS and IQ for less noise...

While it's normal that dual GPU cards are louder than single GPU ones,if for no other reason that they use more power,and the more power it uses,harder it is to cool down while keeping it silent using an air cooler,and it's even worse when thinking about using several cards together in either SLI or crossfire....There's no getting around physics basically.


Having said that,what was the case used in that review?,and were the tests made with an open case or was it closed?,and what distance was the microphone placed at?,and was the measuring device set to A weighting or C weighting for it's mesurements?


What i'm basically saying is that from one hardware review site to the next,there's no real standards to measure relative sound volume in a consistent way,hence why the sound level results are never quite the same between one site and the another anyhow,so me personally,i go more for the actual comments of the person doing the tests.


As the ultimate solution to keep the system near dead quiet,even with Crossfire/SLI setups,even under high overclocks,there's always water cooling,and yes it is a pain in the ass to setup and not exactly cheap,or maintenance free,but if the user has very high end/enthusiast setup,and wants the best performance out of it in terms of overclocks and keep it near silent,nothing beats that....It's a necessary evil basically.

Something like this for instance if you're really concerned about noise and still want to hit high overclocks for the highest possible performance:

Some of the guys over at extreme systems are true artists,and really put a lot of work into making their setups not just hit high overclocks and the best possible performance,but also look amazing,and running pretty silent in the process.

Looks pretty sweet. Only issue is all the heat from the Graphics card goes into the CPU. He would be better with the CPU first and GPU second. Would be even better with separate loops for the CPU and GPU. But it is still very impressive looking. :)

Actually,it is a dual loop system....The green is for the CPU's and chipset and the blue one is cooling the GPU's and ram(rdram runs hot remember?),and it's a skulltrail motherboard with 2 Xeon CPU's and a pair of 9800GX2 cards,and yes,it's extremely expensive.


I did an estimate for my setup a few weeks ago,and between the water blocks for the cards,the one for the chipset and CPU,pump,radiator,fans,reservoir tubing and fittings,it would set me back about 1000$ in parts for a powerfull enough setup to cool the whole system with ease.


Add all the pre-planning to make it look nice,and bleed the system and check for leaks,and this is something that would take several days at least,so if i do it,the only time to do so would be on my vacation period.


This is the water block for the video cards i had in mind:

He was talking about the one in the post that he quoted. Its a single loop.

What always made watercooling a no-go for me was the highly toxic cooling liquid that prevents corrosion. But since there seem to be non toxic alternatives now... may really become an option. Let's see how hot it gets this summer ;)

Short: the GTX 480 will be faster than a HD 5870 but slower than a HD 5970. The HD 5970 will be the fastest card for a while, which means there won't be a dual GPU Fermi card in the near future. The GTX 470 will be somewhere between HD 5850 and HD 5870.
Those are comments from Nvidia partners.

So the question is how much faster is it over the 5870...and at what cost...

I really don't think 20% boost would really mean too much, and the 5870 is sure to drop in price a lot to sell more.

TBH if it was 20% i'd be more than happy. The 5870 is no slouch and if Nvidia's finest is faster then that's all good.

if the 480 is more than 400 squidly diddlys im not buying it id payed 400 for my 280and to be honest i wouldnt pay that again and you do no with companys like evga and so will be more $$....

do you think that nivida will let ati have the performance crown i think not mate.. of course they will have to have something that is faster than the 5970 is a exellent card so they will have to beat it.....

Short translation of the interesting part:

DirectX 11 tesselation performance: according to Nvidia, the GTX 480 is 30% faster than a HD 5870 on average in an unspecified DX11 benchmark run from the Heaven demo. In closeups it is 100% faster, when zooming out so that less polygons have to be rendered both cards give almost the same results.

This doesn't say much about actual game performance though, DirectX 11 and tesselation are currently almost nonexistant in games.

Funny, this has been shown without the screenshot covering the graphs before. And no, it doesn't cover anything relevant ;) I guess Nvidia didn't hear about the Streisand effect yet :p

Don't care about DX11 tesslation. since there will be fully DX11 tessellated games there gonna be another GPU generation. Show me some gaming performance!

TDP may be higher than expected (470 220W, 480 close to 300W), availability will be better than 5870 (which may mean that there will be more 400s than expected or there were less 5870s than expected ;)).

well hopefully if the 480 isnt like $4,$5, or $6 hundred bucks ill get it?

3DMark Vantage results:

X-Mode:
GTX 470 - 7511
HD 5870 - 8730
HD 5850 - 6430
GTX 285 - 6002

Performance Mode:
GTX 470 - 17156
HD 5870 - 17303
HD 5850 - 14300

Unigine results:

4 x MSAA:
GTX 470 ~29fps
HD 5870 ~27fps
HD 5850 ~22fps

8 x MSAA:
GTX 470 ~20fps
HD 5870 ~23fps
HD 5850 ~19fps

GTX 470 Shader Clock 1255 Mhz, Memory Clock 1600Mhz

The GTX 480 will almost definitely not use 512 shader cores.

The final specs will be given to the partners on monday, retailers are worried about the cost performance ratio (which probably means their margin).

If these prove to be true I'll be skipping this generation, especially if they're expensive. I'm hoping to replace my 260's with a single card and still have a good improvement in performance.

If these numbers prove true Nvidia will have the fastest single GPU cards, also they support some interesting features - so everything depends on the cards price in the end. The GTX 470 must not cost more than 300€.

That's about what I was thinking. Can't see it happening, though. I guess we'll see soon enough.

BTW that memory clock doesn't look right. That would be 6400QDR, no?
