Here is the first picture of AMD accelerated processing units in the existing FM1 package and future FM2 package on which the next-generation Trinity APU will be based on. Both packages are very similar, follow AMD's favourite yet archaic PGA design. The pins are physically arranged in a mostly similar fashion, though we don't have a pin map at hand. The difference comes with some of the blanked pins in the sub-central portion of the pin array. The FM2 package has 904 pins, compared to 905 on FM1. One pin is blanked, while a pair of blanked pins are arranged further away from the central cutout.
AMD FM1 and FM2 not compatible

TechPowerUp found a side-by-side photo of AMD's FM1 and FM2 packages. The picture reveals these chips will be incompatible, as the pins don't match.
