the iphone 4 has a 800Mhz Cortex A8.

the n9 a 1Ghz A8 which can easily be overclocked to 1.2 Ghz if you want.

The SGX535 does the same amount of triangles/sec (14m) as the SGX530, but has a higher fillrate (500 vs 1000), don't know how relevant the fillrate is in practice, I guess its not a limiting factor for the n9 screen resolution.

The n9 has 1g ram > 512mb

So compared to the iphone4 i would rate the specs of the n9 better. iphone 5 is another story of course.
