The Snapdragon is NOT based on the Cortex A8.

Qualcomm licenced the ARM v7 instruction set, but not the Cortex-A8 design - the former being a much cheaper licence than the latter, and then Qualcomm went on to design their own core that was mostly compatible with the ARMv7 architecture. But it's certainly not a Cortex A8, as Qualcomm haven't licensed this design from ARM.

The Qualcomm implementation of ARMv7 is generally considered to be less efficient than the ARM Cortex-A8 (which is why Snapdragon has to run at a faster clock to remain competitive) and the TI OMAP3 version of the Cortex-A8 is laid out by hand and not using macros so is generally considered the most efficient implementation of the Cortex-A8 to date.

Add it all up and clock-for-clock an OMAP3 outperforms a Snapdragon, both in terms of raw computational ability and also power consumption.
