R680
DX10.1
65nm
1100mhz core clock
1gb of 2.5ghz GDDR5(based off DDR3)
In all seriousness, I agree with that...accept of course the clockspeeds/mem. It seems ATi is targeting somewhere in the 700-800 range for the R600, so one would assume it's close to the 1ghz mark.
The questions that are burning though are:
1. Will it be a straight shrink to 65nm, ala to get the size down (to < 300mm2), or will they change the architecture by adding more shaders/tmus/whatever, or by redefining those shaders (perhaps something along the lines of 64->96, or vec4->vec5), or will perhaps both be possible and done?
2. Are those old rumors of R600 running at 1.2v to the core true? Because if they are, and R600 runs hot even at that spec (because of it's size, setup, clocks, whatever, at least on A12) it would seem that that spec leaves a lot of room for boosting come revisions. We know ATi's played that game in the past with leverging parts based on stock core voltage (XL/XT). Havn't high-end GPUs in the past been in the 1.4-1.5v range with mid-range at 1.2v? If R600XT/X comes out at 1.2v, perhaps R680 could be a straight shrink to 65nm with 1.4v stock or something, with the smaller area allowing the heat to be reasonable for such voltage, resulting in massive clocks.
3. What spec of GDDR4 will be available in Q3/Q4 of this year? 3.2ghz? 3.6ghz? We've heard both will be available, and that yields are good, yet adoption seems to be slow and samsung is slow to increase bins and Hynix is yet to even come out with something.
