The introductory speeds I am being quoted for the A53 are around 1.4 GHz.
While I do expect to see the A57 pushed higher, whether it will make it to (or above) 2.1 is questionable.

The Cortex-A15 is specified for a maximum clock rate of 2.5 GHz (while current chips using that core don't exceed 1.9 GHz). Even if we take the slowest figure of 4.1 DMIPS for the Cortex-A57, it will take a 2.1 GHz Cortex-A57 to beat a 2.5 GHz Cortex-A15. Do you think the Cortex-A57 will be introduced with a clock rate below 2.1 GHz?
