This explains the hybrid cooling leaks we've seen. As long as temps ( which is really all you should care about ) are kept down I'm all for it.

Yes, people still care about energy usage and heat. You're kidding, right? Why would people ever STOP caring about that?

And no, you do not "throw power consumption out the window" when you overclock. My 980 pushed to 1480 core and 8008 mom does not consume 1 more watt when OCed (while Firestrike Extreme goes up by 14%) because I didn't touch voltage or power limit at all. As least, that's according to my Kill-a-Watt.

Depends on your usage. HBM, even at 4GBs, will probably rock in 4k and multi-monitor setups.

To the average Joe, these things mite be an issue, or to those that don't dabble in custom water cooling...but to me (and I would hazard a guess as to most of OCN), the only concern is overclocking headroom..and when it will actually hit the shelves (A decent price point is always nice too..) I just wish GM200 and this would hurry up and drop on us, I have some money lined up, burning a hole in my hand, waiting ever so impatiently...
I have a small room and during summers my 770 was heating me up something fierce. So heat does matter.

Also I'm already considering flippping the AUSUM switch which means 450W and ability to reach higher clocks.

I'm hoping the rumors are false and the GPU is 20nm.I'm waiting for the right moment to upgrade.
So far all the parts in my main pc are >=40nm excluding SSD and maybe HDD's electronic circuits.
It won't be 20nm, that rumor has been repeatedly debunked. APUs and possibly low end, small die GPUs will be 20nm.

While 280x (for example) is set down on 250W TDP and actually draws around ~320W. So difference is about 70W instead of Nvidias ~150W.

TDP != power usage

Dont try to put me into a bad light here. Hard to argue against facts huh? Everything's the same just the GPU is different. So where did that extra 150W come from all of the sudden? Please do explain.
Almost as bad as the "980 is worse than a 290 or 770" guy.

Once again completely opposite directions of design.
Tonga also introduced compression improvements, so Nvidia isn't alone in that aspect with Maxwell.

The same system, total draw. So that means AMD is taking about what, 10W more on about 100W more TDP marked down?

250W...so we're missing about 100W on Load. So I'm guessing I have to call defeat and say AMD actually puts out too high numbers for their GPUs... cheers.gif

And I wasn't being sarcastic. Sorry mate.

Not a chance.

Definitely some shills posting, hi GT!, but I think some people just can't personally see the appeal of better thermals and power usage OR understand why others do.

I don't think you understand how units of volume work and just how much energy it takes to heat up a room. There's a reason those space heaters for a single room are 1500 watts.

To be fair I think you were making a joke to begin with so I'm probably the one who doesn't understand how jokes work haha.

What??? If you have your desktop in the corner of your bedroom, it doesn't matter if you have your rig air or water-cooled, the same amount of heat is being dispersed out of your case, and it will have the same effect on the room.

Just because you can't feel the 90°C jet of burning air doesn't mean the heat vanishes.

Oh, it takes a fair bit, but, once you're there it's on.

In my 10'x9' computer room...

PC 850W
3 monitors using however much
A/V receiver 450W (something like that)
Sub woofer 450W (peak)
All my network stuff

I also had another PC in here with a 500W PSU and monitor, though I have since moved that to the living room. It helped a lot.

Now granted, the chances of all of my stuff tossing out its max heat at one time is slim, but, you have to reduce heat where you can. Especially once you start hitting the spot I'm at. I couldn't imagine the heat in this room if I had also kept my 2nd 780.

Really though, it only took a single PC OC'ed to turn my room into a oven without having the AC blasting. Not too bad during the summer since I keep the AC at 70, but, during the winter when my ol'lady wants the heat @ 71 - 72... It can easily become a oven in here.

If this comes in at 300 watts and performance 40-50% better than the 290x, that is a pretty good efficiency improvement in my book.

Considering it takes about 400 watts of energy converted to heat at 100% efficiency to heat a 400 sq ft room 1* C in an hour I am going to go ahead and call B.S. on that one.

Ah they are going for the sideways stack with 2.5D interconnectors first, guess that makes sense!

I dont get it, why can't AMD/ATI make lower power consumption architectures? All of their CPUs and GPUs make rooms hot esp in places like florida.
