7770 cards can be overclocked to 1200MHz and whilst I don't see this happening on the One, I'm not sure why they can't approach 1000MHz.

7770 card uses a single small chip... Xbone a big complex chip... there are a  big difference between the two like when you increase the GPU clock you increase the eSRAM clock too.
