my guestimate: GM204 (or 104) part 400-ish mm2 die 70%-ish over GTX 770, 10-20% over 780Ti TDP slightly above 680/770 256 bit MC 4GB VRAM

God I hope not. Sure a 256bit bus will keep prices low, but we need wider lanes on the memory for more bandwidth. Having at least 384bit (512bit is a bit overkill) and lower memory clocks means more efficient and more stable memory and also room for overclocking to increase bandwidth. Remember, the more narrow the memory bus the higher the memory clocks need to be and higher the memory clocks the more power it draws. Take the AMD R9 series as an example, it has 512bit bus but slower clocks memory yet still gives massive amounts of bandwidth. I think AMD needed to go with slower clocks memory as the GPU core it self was set at such a massive TDP (95C target) that any more increase in power draw or heat would of made the card unstable. However, this is not the case with Maxwell as its designed to be very power efficient so its TDP should be low and target temperatures for the core should also be low allowing them to ramp up memory speeds. But still a 384bit bus would be better as this would lead to lower memory clocks yet still more bandwidth.

ive always wondered why manufaturers chose to use 2x6 pin connectors i would think 1x8 would be cheaper and simpler to manufacture plus u would need a million cables running everywhere when u use sli

I'm not sure i understand your logic? 2x6 would be 12 total pins, yet you ask why 8 pin doesn't get used? an 8 would, if an 8 was sufficient enough.....

6 pin = 75 watt 8 pin = 150 watt

yea i would think 1x8 pin for 150w would just be cheaper and cleaner overall instead of 2x6 for 150w

The memory spec: H5GQ4H24MFR-R2C Got the info here: http://www.electronicsdatasheets.com/pdf-datasheets/sk-hynix/h5gq4h24mfrr2c/ http://i.imgur.com/iTLEcvY.jpg MC could be 256, and 384bit Since, gtx 780ti, and 770 both use 7Gbps mem. Unless this is GTX770ti. shrug. -my 2 cents. Companies that use "H5GQ4H24MFR-R2C" Sapphire Radeon R7 260X 2GB OC H5GQ4H24MFR-R2C 336A GIGABYTE Radeon R7 260X H5GQ4H24MFR-R2C 344AC

I hope that stacked Power Connector is just part of the ES and GOES!!!! in the final design.

I think the extra 6 pin could a variation of this specific card that allows for unlocked over clocking potential similar to kingpin. Intact I'd bet my last dollar on it.

8 to 16 GB VRAM? This just gets better.

I'd take a 4-16GB 880 Ti. From what I see it would only be worth upgrading for more Vram at this point, and I'd rather wait for a faster 880 variant if those are the current rumored specs.

Your gonna need a 2000mhz core clock to get the full use of that Ram. Same old old. I cant see the core clock speeds being fast enough until maybe Volta and the Vram is capped. Even though Nvidia know that to make use of the Vram you need more than 2 cards, which means more money for Nvidia.
