The Snapdragon core is entirely custom and not based on A8 but is about 5% faster clock-for-clock than a standard Cortex-A8. Even though Qualcomm have a dual-core Snapdragon it won't beat a Cortex-A9 at the same clock speed since the A9 is at least 20-25% faster clock-for-clock than a standard A8.

No.
That's physically impossible, rpjitendra.
I request others who read this not to post in this thread and bump it up again with useless posts.

For reference, the Samsung Hummingbird is a Cortex-A8 that has been customised to perform certain binary functions using significantly less instructions than normal. Samsung estimates that 20% of the Hummingbird’s functions are affected, and of those, on average 25-50% less instructions are needed to complete each task. Overall, the processor can perform tasks 5-10% more quickly while handling the same 2 instructions per clock cycle as an unmodified ARM Cortex-A8 processor.
