Dumb question. What's the advantage of the small form factor for the majority of people with mid-full size towers? Couldn't they just pack more shit onto a full length card? Or at the very least I'd think extending it would allow for more heat distribution.
Blank PCB that extends a few inches farther.Brings up an interesting point on the aircooled versions, how do you fit a massive +10" heatsink on a small form factor card? You use a different PCB? Have a support bracket/backplate?
It does seem quite short.
edit: So where did he get the picture from...?

Check out some of the wide PCB cards that Nvidia has used.
You could also just mount it to an extended backplate, like what the GTX 760 used.
Well if the 390X will actually retail for $700+, I guarantee it'll be quite a bit faster than the 980. Otherwise it's pretty much DOA.
Still needs some air for VRMs whether that is doable passively is unlikely IMO.
that is why 980ti is what is gonna be out soon to compete against it fool. Like 980 will get a price drop soon. 700$ price tag for that 390x is 99% for sure gonna be only 4gb ram card.
Based on what? they are boasting 50% power savings for the HBM vs GDDR5, only the hottest cards of the last few gens have required active VRM cooling...
The 50% power savings is for the RAM only and will simply amount to single-digit savings, RAM sips power as it is.Based on what? they are boasting 50% power savings for the HBM vs GDDR5, only the hottest cards of the last few gens have required active VRM cooling...

Ohhh, so that's why overclocking RAM adds significantly to the power draw of a GPU?False. It is the memory IC's and the interface which in some cases amounts up to a third of the power consumed.

(it doesn't)
FYI: http://www.samsung.com/us/business/oem-solutions/pdfs/Green-GDDR5.pdf
Even 1.5v GDDR5 consumes only a bit more power than the 1.35v Samsung chip in the above. The Samsung chips in that PDF are lower density, but power doesn't scale linearly in higher density modules. At any rate, let's say that AMD could swap the 290X to HBM, drop-in repacement for the GDDR5 that is in place right now. You wouldn't see a significant drop in power, not enough to write home about. Yes, power efficiency is good, but HBM is not the magic wand that everyone is thinking it is, it is simply a step in the right direction.
*DrOoL*
Take my fucking money now...
Where are you getting 99% sure only 4GB. Would be suicide not to have a 8GB version

So apparently the whole thing is underwater....that or they really need to get a better photographer.
Well lets just pretend those specs are right. That's 5% higher core clock and 45% more cores. It should be 20-25% faster than an OC'd 980 right out of the box. I'd have to imagine it'd OC half decently... plus whatever HBM buys it. I'm still not sold on HBM doing a whole hell of a lot quite yet.
Again, HBM isn't just about saving power consumed by the ICs, which is still ~40-50%, and around ~15-30w of savings depending on the amount of VRAM, but also saving power with the interface, decreasing complexity of the memory controllers as well as PCB complexity.
It is all around better, even better than the jump from GDDR3 to GDDR5.
Other than the fact that HBM isn't a drop in replacement to GDDR5, if you could do that with Hawaii, it would be a ~200-215w card which is down from ~250-275w. You would write home about that.
wtf are you on about? I was responding to DA_SHlT's comment about the 390X being "meh" if it only matched the 980, especially since the rumored price tag is $700+ USD from a semi-reliable German source.
So again, a $700+ USD 390X that just matches the 980 is not "meh", it's DOA, and there will be very few buyers. At the very least I won't be touching it.
One thing would be a question, if slides show HBM chips on some what be a big chip. Question comes to mind is heat that those chips will get subjected to. the water cooled one won't be an issue but air cooled ones it will be. Wonder if that will be long term issues.
Why does it need a AIO water cooler? Is it that inefficient and produces that much heat this these AIOs have become "acceptable" solutions for AMD cards?
This is why... plus, it puts out as much heat as Titan X. I'm guessing you rather have a more expensive, lower performing, louder, hotter card?
Looks more and more likely that the VRMs are also cooled by the block.
