Nvidia Touts (Quiet) 'Fastest DX11 GPU on Planet!'

[saint19]

We need the release date, before that, nobody know the real performance of it (except nVidia).

First things first. That vapor chamber is gonna have to withstand a LOT of temperatures and pressures. Nobody will be happy having water in their computer. Plus, this means your case MUST BE standing upright and the heatsink facing upward. What if you have a case of a different shape and have your mobo horizontal. Yet another problem. Besides, even if they do snatch the performance crown, it wont be long till ATI releases a good card that will just blow it out of the water, hah, maybe it will before they do even =P

the skeptic in me couldn't help but noticed that it requires liquid cool..

exit jokes about making your breakfast enter jokes about heating your shower..

It's likely a slightly redesigned GF100 similar to a less gpgpu heavy version like the GF104 it's why all rumors point to a GF110 instead of GF100b. In other words this is frankly no different then what amd does from year to year, just tweak what you have don't necessarily make a new chip.

The rumours suggest that GF110 has fewer transistors than the GF100 so that makes it a different GPU even if it is only a tweak, just like the HD6xxx's are just tweaked HD5xxx's as you say.

[citation][nom]zak_mckraken[/nom]Pretty much, yes. Not only that, but water boils at 100°C (212°F). I'm not sure I want my GPU to get that hot.[/citation]

That's not the way it works. The boiling point of water might be 100C, but measured Temperature is generally a measure of AVERAGE kinetic energy, not a fixed absolute value. Water left outside in a glass will eventually evaporate, even though the outside temperature is nowhere near 100C. This is because while the average temperature of the water is basically the same as the air temperature, a few of those water molecules (out of the whole bunch) absorb enough energy from the environment to reach that boiling point and evaporate out of the glass.

In anycase, I'm pretty sure this is the same as Saphire's Vapor-X coolers, which I have been fairly happy with in the past. I bet Saphire wasn't the first to do it either.

Water doesnt always boil at 100. It's based on atmospheric pressure. Lower the pressure enough water will boil at 90F. They have a small toy that shows that process.

Phase change is one way to move heat energy.

Sapphire Vapor-X no? Seems like ATI still would be leading in terms of technology.

Just like all the ATi cards that have been using vapour cooling before eh? :lol:

[citation][nom]Restatement3dofTed[/nom]Hope that bad boy's adequately sealed - dropping the cash for the then-fastest DX11 GPU on the market, only to have its water chamber leak onto the rest of your $2000+ system would make for a bad day.[/citation]

Did the heat pipes in your computer burst? Ever heard of that happening before? No? This is the same principal, but with a heat block instead of heat pipes.

I still don't understand how the liquid goes against gravity. The heatsink will be pointing downwards, so their image is wrong. How do you wick the liquid quickly enough in that design? Will the chips now be on the other side of the video card?

 

[rohitbaran]

Fixed fermi.

 

[eyemaster]

[citation][nom]DjEaZy[/nom]... so the GPU will theoretically be not hotter the boiling point of water? so it will be about 100 c'...[/citation]
The boiling point of water is totally dependent on pressure. You can make water boil at 0 degree celcius if you want.

 

[xenorage]

Hope it is good for what has been speculated on price! $600 gonads is a lot of dough for 1 gpu. It will have to compete with 2 gpu setups at that price.

I'd only consider better cooling a bad thing when they need to sell you a phase change unit with your gpu.

 

[chrisv815]

Wish I would have known about this before I bought my 470. When I fire up a game on that thing the FAA calls asking me if I have a jet in my garage.

 

[Gin Fushicho]

47dB's? That's WAY better than before. Well, I'm glad I've been waiting.

 

[d-block]

Factory liquid cooling? Freakin' sweet!

 

[tommysch]

I dont want quiet, I want power. Its like buying a McLaren F1 and whining because its loud.

It would happily buy a 100db, 300+Watt monster if I can get 2x-3x more FPS out of it.

 

[christop]

The selling point does nothing for me I can water cool my GPU and it would be the most quiet gpu ever. I am going to bet this new Nvidia card will be 700 or so.

The boiling point of water at the top of Mount Everest is 69°C.

The manufacturer of the thermal solution can adjust the desired boiling point of the water during manufacturing just by changing the air pressure before sealing the heatpipe loop.

Have you never heard of capillary action? That's liquid moving up a thin tube against gravity. Sintered metal is what's used for the heatpipes.

"Yea yea yea! Come on, get some!"

 

[scrumworks]

AMD/ATI has had vapor chamber coolers since HD2900. Now it's all the sudden big news when nvidia has adopted it. Nvidia marketing crap is impressive.

It doesn't go against gravity, it evaporates at the bottom and condenses on the (cooler) top and sides of the chamber where the fins are... then the condensed droplets run back down the sides and pool in the bottom of the cooler again.

 

[cinergy]

[citation][nom]wiyosaya[/nom]47db is not what I would consider quiet.[/citation]

And when it comes from nvidia marketing, you can add another 5db+ in it.

 

[Emperus]

For all those who believe 47dB is too much noise, go hear the GTX 480 under load.. IMO, this looks exciting.. However, its still a paper claim which, for the major part of it, sounds too good to be all true..

 

[miloo]

just wondering whether GTX460 will have any new price ~
