For some tasks the memory bandwidth available per core is much more important than the number
of cores. This is why the newer GTX 600 series cards are not as fast as one might expect compared
to the 500 series - a lot more cores, but not the mem bw to feed them. And that's why using several
cheaper cards with fewer cores but more bw per core often results in much better performance than
a single card with loads of cores. Try using four GTX 460s and see how it compares to a 670 or 680
for AE.
Transistor count doesn't mean anything though. A newer design might have more elements purely
because of a more sophisticated power delivery system and power management system, which
doesn't translate to better performance, but reduces cost re power consumption. Transistor count
is as useful as the old pointless MIPS metric for CPUs.
