Its not even close to Regor vs Kuma. For one in almost anything that is not a throughput test/workload per clock excavator is anywhere upto 15% faster per clock then kaveri.BTW... Looking at DT Excavator, I wouldn't want AMD to project anything based off it!
It's certainly not even 5% better than PD on average. It wins few but loses more with a landslide!
Absolute performance wise, it's ppp. It needs FAR higher clocks but it doesn't scale at all. It's a mobile chip, simply put, low frequency+graphics optimized.
It's no better than the old Regor chips were at the time. Kuma caned them, literally.

An actual fair comparison would be something like an X6 vs llano. L3 vs no L3 , APU focued vs not. Regor vs Kuma was about cost reduction.
The only way trinity wins out vs excavator per clock is because of the extra L2 and thats completely disregarding TDP. As pointed out by Stilt the L2 is very power hungry and clock limited. if looking at integer IPC out side of the L2 difference there is nothing in excavator that sacrifices performance for lower power.
the funny thing about IPC is the C, so the point of your post was........
