double size != double speed.
you can't just throw a bunch of transistors onto a die and expect it to go faster. you can only push a single transistor so fast untill it gets saturated with charge. to get faster with bigger, you've have to get MUCH more complex, perhaps some switching mechanism to let one set of transistors discharge while another set take over, but I doubt that technology exists, or if it does, than the switching mechanism isn't fast enough.
smaller=cooler
semi-organic transistors=much cooler, less saturation.
