It appears like AMD's next generation desktop CPU might be closer than anyone expected, as pictures of two different CPU's have shown up online at a Taiwanese website. The two CPUs are labelled ZD160110J4BGA and ZD180110J4BGA.
The site in question has tried to decode what the different model names mean, but they don't follow the old modelling scheme, nor do they seem to folllow the new one that AMD announced earlier this year.
The chips are diffused in Germany, but made in Malaysia, so these are very likely 65nm parts.
Both CPU's are AM2+ models and one could guess that the 160 and 180 numbers refers to clock speeds, 1.60GHz and 1.80GHz, but this is pure speculation for now.
We're just going to have to wait and see what happens, but in the mean time, you can check out the pictures here (note that the site is in Chinese)
