Just bumping this for the lulz.
27/03/2010 The new Nvidia cards have been released !
Performances seem to be decent but price isn't.
Also being 6+ months late doesn't help.



loool

These cards would have been decent if they launched approximately at the same time, like gtx 280 and 4870, but since Nvidia is so late, they were expected to show more serious performance gains, and not 5-10% over 5870, while consuming flat out 50% more power.

enjoy burning everything in your case with the exposed heatsink that reaches 80C LOL!

Closer to 90 C actually not mention space shuttle launch fan loudness under load.

The cards are under-performing horribly due to the time of the launch. People are guessing that the delays and shit were due to nVidia trying do "stealth" OCs on these cards when it became obvious it wasn't standing up toe to toe with ATI's tops.

The good news for nVidia fanboys is that it doesn't seem like this card is the defining card of this generation unlike the previous launch cards, it's not completely using all of its abilities yet.

The problem is that ATI is stretching into multicores already with better results of this nVidia release so nVidia once again is playing catch up.

That doesn't even matter... the 5870 and 5850 and 5970 and the new 5770 are not exclusive to venting out of the case, all those cards vent in case and all reach high temps. Just get a decent case

that's not true, the reference cooler for 5850 / 5870 all vent outside of the case the 5770 might not but it runs a lot cooler than these higher end cards. the gtx 480 on the other hand has part of its heatsink exposed outside of the shroud and probably takes up half the surface of the card. it's not that big of a deal since people buying high end cards need huge cases to fit them anyway but it's still funny.

"throttle, dip back to 99, and then hop back up to 100. What you really need to be careful with in a closed case, though, is a rising ambient. The Radeon HD 5870’s decked-out bracket doesn’t have a full slot’s worth of ventilation anymore, so half of the card’s air actually blows out the top back into your chassis."

Not all of the warm air is blown directly out of the chassis though, as there are some vents along the top of the heatsink shroud (in the red plastic portions, for example). Again, there's channeling on the underside of the shroud to ensure that air is ushered in the right direction.

Judging by the size of the vents on the top edge of the shroud and feeling around the area for airflow, we believe that no more than a third of the exhausted air goes back into the chassis

"Ever since the release today of the GeForce GTX 400 series there has been much discussion regarding the noise levels the cards make under load. Especially the GTX 480 is topic of much discussion. Some sites show numbers up in the 60 to 70 DBa, which honestly just isn't right.

What happens is that people measure differently and often subjectively. If you place a DBa gun a CM away from the graphics card ventilator then sure, you record really high noise levels. But if you play games, do you place your ear directly on the air exhaust ? Of course not, that just does not make sense to us.

We measure real-life conditions. That means we take a distance of 75cm from the PC and place a DBa gun pointed at the PC. We assume your PC chassis is closed and not open, so is ours. Now to proof to you that the GTX 480 is noisy, but definitely not what some media make it claim to be I made two video's of the GTX 480 in idle and under heavy stress with Furmark.

The end result is A PC creating roughly as much noise as say a GeForce GTX 295. And again, we are not disputing that this isn't noisy, contrary .. it is noisy alright. But to say it's at a the level of 60~70 DBa makes no sense

Have a look and listen to the videos.

Above video shows the GeForce GTX 480 in IDLE = ~ 37 DBa.

Above video shows the GeForce GTX 480 heavily stressed with Furmark = ~ 45 DBa

And that my friends is how we measure. We are not saying that other websites are wrong in their measurements, no Sir. We measure in a real-life situation, and that's roughly the distance where your ears are positioned.

There is one more note I like to make, some sites made videos of the noise levels as well, and it is banging noisy. Just like our video, a video camera will always compensate and increase microphone levels when needed. Making that recording sound out of proportion.

Add to that this, if the only sound recorded is the noise of the PC, at what volume should you play it back to be able to have that volume level representative of what the noise levels really are ?."

yeah, but Guru3D also has one of the best series of benchmarks :/

Admittedly I have only checked Guru3D, Tom's, and Anandtech.

I checked several sites the one saying the card is like a leafblower don't really seem to have valid test.

HardOPC for example is using a dB rating not a dBA rating to take into account how we hear. They also did their test 6 inches away from the card... do you play with your ears 6 inches away from the card

3d guru used a certified dBA tester at 30 inches away from the pc and at a closed set up. Like most of us, and even take into consideration that most people are closer to 36-48 inches away from the card when the PC is on the ground instead of a set up with it on your desk.

Most of us run a closed case not an open benchmarking rack.

And 3d guru is one of the premier sites in terms of journalism while reviewing.
