Interconnect capacitance, especially in deep sub-micron processes, has a significant effect on the performance and power. At 1um, you could ignore the interconnect delays. At 0.25um and below, the transistor delay is insignificant compared to interconnect delay.
The 0.6mW/MHz power dissipation figure for ARM7TDMI does not include I/O, any cache memory or anyother peripherals. Basically it is just the core itself - equivalent of about 40K gates.
