AMD Justifies Using Liquid Chamber Tech On Upcoming 7900-Series Cards

videocardz.com brings us a photo showing the benefits of AMD's new liquid chamber technology over the standard vapour chamber technology used in current heatpipe cooling solutions. There's quite a few benefits, some of which are no drying out, physical robustness and greater reliability. Indeed, can you imagine the disastrous effect on your graphics card of having the cooling system spring a leak during an intense gaming session? Doesn't bear thinking about… Certainly the era of having to replace your graphics card's shrill and inefficient cooler with a high performance aftermarket one are long over, as stock coolers are now generally of very good quality. The liquid chamber system will be used by all AMD's partners who stick to the reference design. Check out the photo for the full info.

The G92B are also lower VOLTAGE. Which leads to lower WATTAGE. There is NO LESS power consumption just because die size decreases. There HAS TO BE a voltage change as well.

cdawallWith better manufacturing you get lower leakage chips that run at lower voltage that in turn lowers TDP. Yet again manufacturing die size has nothing to do with TDP.
Have you seen the specs for the HD7870 yet? It's a die shrink of HD6970 and it's power requirement dropped from 250W for HD6970 to 120W for HD7870. Now, do you really think the HD7870 is going to have the same cooling requirement as HD6970? LESS cooling is going to be required and that is solely because of the die shrink because otherwise they are identical with the same basic specs.

Reference heatsink are all inferior to the aftermarket ones. How can one come to the conclusion that stock coolers are good these days (EDIT: OP said High Quality, w/e the heck that means for good performance)? Pass the dutch to the left before posting... :p

This is interesting but I run an open bench, thus my card isnt orineted like that, so it would see to be less effective, no?

I think nvidia's stock coolers on the 8800 GTX, GTX 285, GTX 295 & GTX 580 are all good. I'm saying this, as I have all of these cards. The fact that a third party one had better be better, you betcha!
