Indeed.

Feature comparison here:

Will post some benchmarks comparing the two (under linux) once
I get a pi2, hopefully by this Wednesday. [How did they miss
calling it 2pi or tau?]

The way I see it, the RPi Foundation knew they had painted
themselves in a corner with the 2835. Any new design would've
been hugely disruptive.  By just replacing the processor core
and leaving rest of the cruft + GPU exactly as before they
managed to get the 2836 out in a relatively short time and all
the hardware addon will continue to work. Now that they've
escaped, I expect to see more designs.
