I think there are three fundamental improvements at play here:
1) Slightly upgraded IGP arch (it's about due).
2) Increased IGP clockspeeds (I think there's a process shrink and there's definitely room for an increased thermal envelope from moving it into the CPU package [that has a much better guaranteed cooler] and out of the NB [that has a dinky passive thing plus all the other stuff on the same die])
3) Increased memory bandwidth due to improved memory controller on the Clarkdale (compared to G43/45's MC).
I could be totally wrong on all three points...I have no actual knowledge of the innerworkings of Clarkdale, if I did, I couldn't talk about it![]()
