I so wanted a 780 Lightning but I think I will wait for these now (or buy a Lightning and sell it when these come out...).

no new leaks? Ok, i can start ...
Hawaii:
Node: 28nm
GPU size around 470-480 mm2
DP Ratio 1:2
TDP higher then 250W for highest SKU
.
.. to be continued :)
I think, size seems too big. I know, is not possible to be lower at the same process, but over 400 mm?
what is dp ratio?
Guys, chill a bit and don't believe everything someone posts here.
i am not someone :)
Lmao holy :banana::banana::banana::banana: its Jesus of Silicon
Double precision, aka DP or FP64, i.e. extremely accurate calculations needed for scientific research.
Single precision, aka SP or FP32, i.e. general compute/shader performance.
1/2 means that if Hawaii has ~5.4TFlops of SP, DP would be ~2.7TFlops.
7970 had 1/4 DP rate and Titan has 1/3 DP rate.
Edit- Forgot to ask if anyone knows if DP is important/used for Radeon Sky product line.
I don't think it would but I'm not sure.
Re Edit- From some of the marketing/press release docs I found, it doesn't appear to use/need DP at all since the docs make no mention of DP performance.
I think you are correct Olivon ;).
who?
HIS R9 280X iPower IceQ X? Boost Clock 3GB GDDR5 PCI-E DLDVI-I/HDMI/2xMini DP
it seems, first will be Gaming card with cutted GPU, and full GPU only for FirePro SKUs
Yes, in first gaming SKU "D9" will be only 384-bit mem controller.
Im really looking forward for D day...I think about performance - around 5-10% better than GTX 780? What do you think guys? But Im afraid from power consumption in load, if is it big card...
Pedant One seems to be in all probability OBR a guy with a history of leaks and douchebaginess .However he was more often than right spot on regarding the pure specs and data (while whining to extreme in the "opinion" section").Most recent big info i recall was performance data few months before release of bulldozer, on which he was disappointingly right.
As for the cards, this round im more interested in mid end to be honest, im on this 6950@6970 for eternity now and still pretty much all games play flawless :-/ ,thats of course for folks with FULLHD single monitor setups.
On a side note ,is DP performance related to bitcoining strength ?
Hawaii die should indeed be something between 470-511 sqr mm, atleast 30% larger than Tahiti.
The die is rectangular shape btw.
Here is some more info
"GPU-Z 0.7.3:
Added preliminary support for AMD Radeon R7 240, R7 250, R7 260X, R9 270, R9 270X, R9 290, R9 290X"
Also appears Vesuvius may be their dual GPU card

"It seems that someone from HIS made a huge mistake today by posting more information about the future AMD products.
AMD Radeon R9 280X is a successor to Radeon HD 7970"

Doesn't seem to be so impressive. Then again I don't think Nvidias the first Maxwell GPU's next year will be double the performance of a 780/Titan either. They will need a die shrink for that.
